Anxiety and Depression Scores in Patients Subjected to Arterial Revascularization for Critical Limb Ischemia.

Ann Vasc Surg 2021 May 2. Epub 2021 May 2.

Hospital Israelita Albert Einstein, Avenida Albert Einstein, , Morumbi. São Paulo, SP Brazil.

Objectives: This study aims to examine the changes in anxiety and depression scores in 138 patients with critical limb ischemia (rest pain or gangrene) who had no previous psychiatric history, at 30 days and 6 months after surgical revascularization.

Methods: Patients were submitted to a questionnaire-based evaluation using the Beck Anxiety and Depression Inventories before surgery (no more than three days before surgery) ("Pre-Op"), 30 days after surgical revascularization ("Early PO") and at least 6 months after surgical revascularization ("Late PO"). The cut-off scores for depression were (1) < 10, no depression or minimal depression; (2) 10‒18, mild to moderate depression; (3) 19‒29, moderate to severe depression; and (4) 30‒63, severe depression. The cut-off scores for anxiety were (1) < 8, no anxiety or minimal anxiety; (2) 8‒15, mild anxiety; (3) 16‒25, moderate anxiety; and (4) 26‒63, severe anxiety.

Results: No perioperative mortality was observed 30 days after surgical revascularization. Thirty-nine (28.2%) patients underwent major (above-ankle) amputation within 30 days. Mean anxiety and depression scores, respectively, declined from 12.48 ± 9.74 (mean ± SD) and 16.92 ± 12.48 preoperatively to 4.89 ± 7.04 and 6.52 ± 9.36 postoperatively (P<0.001, both). Anxiety and depression scores were not significantly affected by preoperative comorbidities (systemic arterial hypertension, diabetes mellitus, previous stroke, and smoking), affected arterial territory (aortoiliac, femoropopliteal, or infrapopliteal), or surgical technique (open surgery vs endovascular therapy). Only patients undergoing amputation within 30 days showed no improvement in depressive symptoms.

Conclusions: Patients with critical limb ischemia have a high incidence of anxiety and depressive symptoms, which improve considerably after successful surgical revascularization. Major amputation was associated with a lack of improvement in depression scores. A formal psychiatric evaluation may be beneficial in patients who show no improvement in depressive symptoms.

Arm mobilization provokes deformity of long-term indwelling ports implanted via the jugular vein.

J Vasc Surg Venous Lymphat Disord 2021 Jul 31;9(4):998-1006. Epub 2020 Oct 31.

Vascular Surgery Department, Hospital Israelita Albert Einstein, São Paulo, Brazil.

Background: The incidence of totally implantable catheter fracture ranges from 0.48% to 5.00%, and these fractures represent a potentially fatal complication. The fracture mechanism of catheters implanted via the jugular vein is unclear, and whether extreme arm movements represent an additional risk factor for repetitive stress of the material remains unknown. The aim of this study was to demonstrate and classify catheter deformations caused by extreme arm mobilization and associations with changes in catheter function and displacement.

Methods: We analyzed the fluoroscopy images of 60 consecutive patients undergoing long-term indwelling port implantation via the jugular vein. Three images were taken: arm in maximal abduction, maximal frontal elevation, and maximal adduction. The images were compared with an image of the remainder of the arm. We analyzed three catheter regions to classify the deformity: A, connection between catheter and reservoir; B, the catheter's subcutaneous tunnel; and C, the catheter's entrance in the jugular vein. The deformations were classified in comparative manner as follows: 0 (no changes), 1 (minor changes, new slightly curvatures with an angle of >90°), and 2 (major changes, new severe curvatures with angles of ≤90°). In each position, catheter function (injection and aspiration) and displacement of the reservoir and tip were analyzed.

Results: Only 15% of patients did not show a deformity; 33.3% had a deformity in only one position, 47.7% in two positions, and 10% in three positions. Minor deformities were observed in 70% of patients and major deformities in 40%. Moreover, 25% of patients presented both major and minor deformities. Major deformities were observed in 25.0% of patients on maximal frontal elevation, in 23.3% on maximal adduction and in none on maximal abduction. Region B was the most affected, with 57.8% of all minor deformities and 78.1% of all major deformities. No change in function was noted in 91.7% of the catheters. Maximal arm adduction resulted in greater vertical and horizontal displacement of the catheter tip and horizontal displacement of the reservoir. Higher body mass index values were associated with major deformities.

Conclusions: Maximal frontal elevation and maximal adduction were associated with major catheter deformities, and the subcutaneous tunnel region was the most deformed catheter region. An association between major catheter deformity and high body mass index was noted; in contrast, no association between the severity of catheter deformity, tip or reservoir displacement, or worsened functioning was observed.

Comparative Analysis of Artery Anatomy Evaluated by Postmortem Tomography, CT Angiography, and Postmortem and Predeath CT Scans.

Ann Vasc Surg 2021 Apr 17;72:124-137. Epub 2020 Sep 17.

University of São Paulo, Faculty of Medicine, São Paulo, Brazil; Hospital Israelita Albert Einstein, São Paulo, Brazil.

Background: To date, no study has been performed analyzing changes in the vascular system comparing paired examinations of patients alive and after death with the use of cardiopulmonary bypass and computed tomography (CT) angiography.

Materials And Methods: The aim of this study was to analyze in a large series (38 patients) the aorta and its branches by CT (without contrast) and CT angiography of patients still alive and after death comparing their diameters and length variations.

Results: The variation between in vivo tomography and virtopsy methods was greater in the evaluation of distances between vascular segments than in the diameters; less than 30% of the distances evaluated in the entire study had acceptable variation between methods, regardless of the use of contrast scans. We observed better repeatability rates in the comparison between in vivo and postmortem contrast-enhanced examinations. Comparing the examinations of the still alive individuals with the contrast-enhanced tomography after death, we observed a higher concordance rate. The best variations between the methods were observed in the evaluation of the diameters in the contrast-enhanced examination of the ascending aorta, aortic arch, thoracic aorta, and thoracoabdominal transition.

Conclusions: The measurements obtained in postmortem angiography images partially reflect the vascular anatomy of the main branches in the thoracoabdominal region in vivo. However, postmortem CT without contrast was not performed in the same comparison. We believe that adjustments to the contrast injection technique may eventually improve these results.

Lower Limb Revascularization for Peripheral Arterial Disease in 10,951 Procedures over 11 years in a Public Health System: A Descriptive Analysis of the Largest Brazilian City.

Ann Vasc Surg 2021 Jan 8;70:223-229. Epub 2020 Aug 8.

Hospital Israelita Albert Einstein, São Paulo - SP, Brazil; Faculdade Israelita de Ciências da Saúde Albert Einstein (FICSAE), Hospital Israelita Albert Einstein, São Paulo - SP, Brazil.

Background: Worldwide, peripheral arterial disease (PAD) is a disease with high morbidity, affecting more than 200 million people. Our objective was to analyze the surgical treatment for PAD performed in the Unified Health System of the city of São Paulo during the last 11 years based on publicly available data.

Methods: The study was conducted with data analysis available on the TabNet platform, belonging to the DATASUS. Public data (government health system) from procedures performed in São Paulo between 2008 and 2018 were extracted. Sex, age, municipality of residence, operative technique, number of surgeries (total and per hospital), mortality during hospitalization, mean length of stay in the intensive care unit and amount paid by the government system were analyzed.

Results: A total of 10,951 procedures were analyzed (either for claudicants or critical ischemia-proportion unknown); 55.4% of the procedures were performed on males, and in 50.60%, the patient was older than 65 years. Approximately two-thirds of the patients undergoing these procedures had residential addresses in São Paulo. There were 363 in-hospital deaths (mortality of 3.31%). The hospital with the highest number of surgeries (n = 2,777) had lower in-hospital mortality (1.51%) than the other hospitals. A total of $20,655,272.70 was paid for all revascularizations.

Conclusions: Revascularization for PAD treatment has cost the government system more than $20 million over 11 years. Endovascular surgeries were performed more often than open surgeries and resulted in shorter hospital stays and lower perioperative mortality rates.

Combined Angioplasty Technique of the Carotid Territory and Supra-Aortic Trunk by Double Access (Cervical and Limbs) for Tandem Lesions.

Ann Vasc Surg 2020 Oct 25;68:570.e9-570.e15. Epub 2020 Apr 25.

Department of Vascular and Endovascular Surgery, Hospital das Clinicas HCFMUSP, Faculdade de Medicina, Universidade de Sao Paulo, Sao Paulo, SP, Brazil.

Background: The carotid stent angioplasty (CAS) has been the main option for patients with high cardiovascular risk and carotid stenosis. The common femoral artery is still the most used access site; however, the aortic arch manipulation is a critical moment for cerebral embolization. Carotid transcervical access should be considered as a good alternative access route for CAS. Tandem lesions combining supra-aortic trunks and ipsilateral carotid bulb critical stenosis pose a great challenge for the vascular surgeon.

Methods: This is a retrospective descriptive study based on medical records of our institution. We report 2 cases of complex cerebral vascular insufficiency and discuss therapeutic options and strategies to protect the cerebrovascular territory avoiding microembolization, as well as demonstrate an alternative and safe total endovascular approach for those cases.

Results: We describe the approach of 2 complex cerebral vascular insufficiency cases: case 1, a 63-year-old male with previous ischemic stroke, right internal carotid artery (ICA) occlusion, left ICA stenosis >70%, and critical stenosis of the origin of common carotid artery (CCA); case 2, a 68-year-old female with previous ischemic stroke, left ICA occlusion, brachiocephalic trunk critical stenosis, hypoplastic right vertebral artery, and aortobi-iliac chronic occlusion. In both cases reported here a challenging solution was chosen, little described in the literature, with cerebral filter protection as the first step. In addition, a literature review was performed to discuss the different approach options for tandem injuries of the supra-aortic trunk and carotid bulb.

Conclusions: Our initial experience with total endovascular treatment of complex tandem lesions of the carotid territory and supra-aortic trunks show that transcervical access, coupled with distal protection filter device on the first step, is a safe and effective technique for preventing neurological events.

Epidemiological Analysis of Carotid Artery Stenosis Intervention during 10 years in the Public Health System in the Largest City in Brazil: Stenting Has Been More Common than Endarterectomy.

Ann Vasc Surg 2020 Jul 10;66:378-384. Epub 2020 Jan 10.

Faculdade Israelita de Ciências da Saúde Albert Einstein (FICSAE), Hospital Israelita -Albert Einstein, São Paulo, Brazil; Albert Einstein Israelite Hospital, São Paulo, Brazil.

Background: Stroke is the second leading cause of death worldwide with approximately 5.7 million cases/year, and carotid atherosclerosis accounts for 10 to 20% of cases.

Methods: In Brazil, the Unified Health System (Sistema Único de Saúde [SUS]) is a tax-funded public health care system that provides care for roughly half the population. São Paulo is the eighth largest city in the world with an estimated population of over 12 million people, of whom more than 5 million rely solely on SUS. This study aimed to describe rates of carotid artery stenting (CAS) and carotid endarterectomy (CEA) performed between 2008 and 2017 in the city of São Paulo through web scraping of publicly available databases.

Results: Three thousand seven hundred and four carotid revascularization procedures were performed between 2008 and 2017, of which 2,432 were CAS (65.7%). Rates of CAS ranged from 59.9% in 2016 to 86% in 2011. There were 57 in-hospital deaths (1.54%), 34 after CAS (1.4%; 34/2,432) and 23 after CEA (1.81%; 23/1,272) (P = 0.562). SUS reimbursements were US $7,862,017.09 (81.44% of all reimbursements) for 2,432 CAS procedures and US $1,792,324.06 (18.56%) for 1,272 CEA procedures. Average SUS reimbursement for CAS (US $3,232.73) was more than double than that for CEA (US $1,409.05).

Conclusions: In a city whose population exceeds that of some European countries, costs of CAS and CEA to the public health care system totaled more than US$ 9 million over 10 years. Epidemiologically, CAS was performed more commonly than CEA with no difference in in-hospital mortality between CAS and CEA, but reimbursements were 2.29 times higher for CAS. The low adoption of CEA in São Paulo is in contrast to countries where utilization rates are higher for CEA than for CAS.

Einstein (Sao Paulo) 2019 Jul 10;17(4):eGS4282. Epub 2019 Jul 10.

Hospital Israelita Albert Einstein, São Paulo, SP, Brazil.

Objective: To compare medication errors in two emergency departments with electronic medical record, to two departments that had conventional handwritten records at the same organization.

Methods: A cross-sectional, retrospective, descriptive, comparative study of medication errors and their classification, according to the National Coordinating Council for Medication Error Reporting and Prevention, associated with the use of electronic and conventional medical records, in emergency departments of the same organization, during one year.

Results: There were 88 events per million opportunities in the departments with electronic medical record and 164 events per million opportunities in the units with conventional medical records. There were more medication errors when using conventional medical record - in 9 of 14 categories of the National Coordinating Council for Medication Error Reporting and Prevention.

Conclusion: The emergency departments using electronic medical records presented lower levels of medication errors, and contributed to a continuous improvement in patients´ safety.

The Need for a Vena Cava Filter in Oncological Patients with Acute Venous Thrombosis: A Marker of a Worse Prognosis.

Ann Vasc Surg 2019 Oct 23;60:35-44. Epub 2019 Feb 23.

Full Professor of the Discipline of Vascular Surgery, Hospital das Clínicas da Faculdade de Medicina, University of São Paulo, São Paulo, Brazil.

Background: Active cancer is found in approximately 20% of patients diagnosed with venous thromboembolism. This condition is more prevalent in patients with advanced and metastatic cancer and is the second largest cause of death among patients with active neoplasm. Many of them have contraindication for anticoagulation and needs an inferior vena cava filter to be implanted, but a large proportion of these patients have very low survival after filter implantation. Our aim was to verify whether the need for filter implantation represents an independent indicator of poor prognosis in oncological patients and to identify subgroups with a greater survival.

Methods: This study included a retrospective analysis of 247 oncologic patients with acute proximal venous thrombosis. We compared survival between 100 consecutive patients who needed vena cava filter (FILTER group) versus a control group of 147 patients in whom anticoagulation was possible (ANTICOAGULATION group). We verified survival, cause of death, filter's indications (clinical and surgical), and factors that might lead to worse prognosis.

Results: Risk of death was 8.83-fold higher in the FILTER group than that in the ANTICOAGULATION group, a greater risk than the presence of metastasis (OR: 2.47). Death was significantly more frequent in patients subjected to filter implantation because of clinical indications (93.2%) such as high risk of or recent bleeding and an adjusted risk of death of 2.24-fold higher in a multivariate analysis.

Conclusions: The need to implant a vena cava filter in a patient with cancer is a marker that indicates patient's disease severity and worse prognosis. Survival was longer in the subgroup of patients who underwent filter implantation before oncologic surgery, probably because of a better status performance and less clinical complications.

Leadership potential of physicians in a public teaching hospital in the city of São Paulo.

Einstein (Sao Paulo) 2019 Jan 21;17(1):eGS4191. Epub 2019 Jan 21.

Faculdade de Ciências Médicas , Santa Casa de São Paulo , São Paulo , SP , Brazil .

Objective: To analyze the leadership potential of physicians in a public hospital in the city of São Paulo.

Methods: A descriptive pilot study, in which 40 assistant physicians and medical residents were randomly selected to receive an electronic invitation of the company Caliper Estratégias Humanas do Brasil . To those who accepted it, a link was sent to fill out a personality evaluation focused on the work, comprising 112 alternatives related to 21 domains of 4 performance areas. According to the Caliper Profile Questionnaire, the ipsative measures expressed as a percentage are distributed on a Likert scale, and three categories are established based on behavioral tendencies at work: need for improvement, moderate and high potential.

Results: A total of 47.5% of physicians invited accepeted taking part in the study. Regarding to leadership, the need for improvement was over 30% among the evaluated physicians. In the interpersonal relationship analysis, only 18.4% of assistant physicians and 37% of medical residents required improvement. The percentage of physicians who needed improvement in problem-solving and decision-making was similar among the assistant and resident physicians (12.6% versus 14%). In the evaluation of personal organization and time management, we obtained similar percentages in assistant physicians and residents who needed improvement (14% in both groups). High potential leadership was observed in these domains (18.4% and 20% for assistant physicians and residents, respectively).

Conclusion: The physicians assessed presented high leadership potential in 25% of the cases, requiring improvement in the performance domains, such as interpersonal relationship, problem solving, decision-making, personal organization and time management.

Clinical, ultrasonographic and histological findings in varicose vein surgery.

Rev Assoc Med Bras (1992) 2018 Aug;64(8):729-735

. Medical Science Faculty of the Santa Casa of São Paulo, São Paulo/SP, Brasil.

Objective: This study aims to correlate the demographic data, different clinical degrees of chronic venous insufficiency (CEAP), ultrasound findings of saphenofemoral junction (SFJ) reflux, and anatomopathological findings of the proximal segment of the great saphenous vein (GSV) extracted from patients with primary chronic venous insufficiency (CVI) submitted to stripping of the great saphenous vein for the treatment of lower limb varicose.

Method: This is a prospective study of 84 patients (110 limbs) who were submitted to the stripping of the great saphenous vein for the treatment of varicose veins of the lower limbs, who were evaluated for CEAP clinical classification, the presence of reflux at the SFJ with Doppler ultrasonography, and histopathological changes. We study the relationship between the histopathological findings of the proximal GSV withdrawal of patients with CVI with a normal GSV control group from cadavers.

Results: The mean age of the patients was higher in the advanced CEAPS categories when comparing C2 (46,1 years) with C4 (55,7 years) and C5-6(66 years), as well as C3 patients (50,6 years) with C5-6 patients. The normal GSV wall thickness (mean 839,7 micrometers) was significantly lower than in the saphenous varicose vein (mean 1609,7 micrometers). The correlational analysis of reflux in SFJ with clinical classification or histopathological finding did not show statistically significant findings.

Conclusions: The greater the age, the greater the clinical severity of the patients. The GSV wall is thicker in patients with lower limb varicose veins, but those histopathological changes are not correlated with the disease's clinical severity or reflux in the SFJ on a Doppler ultrasound.

Number of Preoperative Hyperhidrosis Sites Does Not Affect the Sympathectomy Postoperative Results and Compensatory Hyperhidrosis Occurrence.

Thorac Cardiovasc Surg 2019 Aug 2;67(5):407-414. Epub 2018 Aug 2.

Division of Vascular and Endovascular, Department of Surgery, Hospital das Clínicas da Faculdade de Medicina, Pinheiros, University of São Paulo School of Medicine, University of São Paulo, São Paulo, Brazil.

Background:  Patients with primary hyperhidrosis present with sweating in two or more sites in nearly 85% of cases. In this study, we examined whether the number of hyperhidrosis sites is related to the surgery outcomes.

Methods:  One hundred ninety-three hyperhidrosis patients who underwent bilateral videothoracoscopic sympathectomy after failure or dissatisfaction with clinical treatment were distributed into three groups based on the number of hyperhidrosis sites (one site, two sites, and three or more sites of hyperhidrosis). The primary endpoints in the study were as follows: quality of life prior to surgery, improvement of quality of life after surgery, clinical improvement of sweating, presence or absence of compensatory hyperhidrosis, and general satisfaction after 1 month of surgery.

Results:  Patients with two or more hyperhidrosis sites had worse quality of life before surgery than patients with a single hyperhidrosis site. There was an improvement in the quality of life in more than 95% of the patients, clinical improvement in more than 95% of patients, severe compensatory hyperhidrosis in less than 10%, and low general satisfaction after 1 month of surgery in only 2.60% of the patients, with no differences among the three groups.

Conclusions:  Patients with more than one preoperative hyperhidrosis site present worse quality of life prior to surgery than those with a single hyperhidrosis site, but the number of hyperhidrosis sites before surgery does not affect surgery outcomes.

The relation between age and outcomes of thoracic sympathectomy for hyperhidrosis: The older the better.

J Thorac Cardiovasc Surg 2018 10 7;156(4):1748-1756. Epub 2018 Jun 7.

Department of Vascular and Endovascular Surgery, Hospital Israelita Albert Einstein, São Paulo, São Paulo, Brazil; Vascular and Endovascular Division, Department of Surgery, University of São Paulo School of Medicine, São Paulo, São Paulo, Brazil.

Objective: Several factors may potentially influence the efficacy and patient satisfaction after bilateral thoracic sympathectomy as the treatment for hyperhidrosis, but few studies have specifically analyzed the impact of age on the efficacy of this treatment, the occurrence of compensatory hyperhidrosis (CH), and variations in the quality of life.

Methods: We retrospectively analyzed the effect of age, body mass index, surgical techniques, quality of life before surgery, betterment in the quality of life after surgery, clinical improvement in sweating at the main site, and the occurrence and intensity of CH in patients with hyperhidrosis (n = 1633) who underwent bilateral sympathectomy.

Results: Quality of life improved in more than 90% of patients, and severe CH occurred in 5.4%. Age did not affect these outcomes. The older, the greater reduction in sweating, and CH was linked to other variables (body mass index, craniofacial hyperhidrosis, and level of resection).

Conclusions: We observed that patients with old age reported an improvement in sweating in the main site of hyperhidrosis. Sympathectomy outcomes in older patients are similar to those observed in younger patients in terms of quality of life improvement and occurrence of CH.

Paraplegia of Lower Limbs Caused by a Segmental Thrombosis of the Descending Thoracic Aorta Reversed with Endovascular Treatment-A Case Report and Literature Review.

Ann Vasc Surg 2018 Jul 5;50:300.e5-300.e10. Epub 2018 Mar 5.

Full Professor of the Discipline of Vascular Surgery, Hospital das Clínicas da Faculdade de Medicina, University of São Paulo, São Paulo, Brazil.

Background: Transient paraplegia of the lower limbs is a rare condition and, when has a vascular etiology, is usually associated with thromboembolic events, aortic dissection, aortic aneurysms, or as a complication of the surgical correction of those diseases. There is no case reported of acute paraplegia caused by a segmental thrombotic subocclusion of the descending thoracic aorta.

Case Report: We report a not yet described clinical situation of a young patient (51 years) admitted to the emergency care department for treatment of systemic arterial hypertension of difficult control with 4 antihypertensive medication classes. At the intensive care unit for treatment with intravenous antihypertensive medication, the patient evolved with acute paraplegia and a segmental thrombotic subocclusion of the descending thoracic aorta was diagnosed. He was submitted to endovascular treatment with total recovery of the deficits.

Conclusions: The previously normal descending thoracic aorta may be a site of segmental thrombosis and may lead to paraplegia. Early endovascular treatment can reverse this type of situation.

Endovascular Treatment of Penetrating Injury to the Vertebral Artery by a Stab Wound: Case Report and Literature Review.

Ann Vasc Surg 2017 Nov 6;45:267.e1-267.e5. Epub 2017 Jul 6.

Department of Vascular Surgery, Clinics Hospital, School of Medicine, University of São Paulo, São Paulo, Brazil.

Background: We describe a unique case of a patient with penetration of the cervical region by a stab wound, who required emergency care for the controlled removal of the knife and for vertebral artery trauma (VAT) treatment. Although rare, VAT causes high morbidity and mortality.

Methods: A patient admitted for emergency care was diagnosed with traumatic complete section of the vertebral artery by a knife and underwent removal of the knife under radioscopic supervision and vertebral artery embolization with coils.

Results: The knife was removed successfully, the bleeding was controlled, and the patient did not present any sequelae.

Conclusions: In the authors' experience, a patient in an emergent state due to VAT can be treated effectively and quickly with proximal embolization.

Endovascular Treatment of Late Aortic Erosive Lesion by Pedicle Screw without Screw Removal: Case Report and Literature Review.

Ann Vasc Surg 2017 Feb 22;39:285.e17-285.e21. Epub 2016 Sep 22.

Spine Surgery Division, Laboratory of Medical Investigation, Instituto de Ortopedia e Traumatologia, Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, São Paulo, Brazil.

Background: Aortic lesions are uncommon complications in spine surgery, but potentially fatal, because they can cause massive bleeding and hemodynamic instability. We report the endovascular treatment of late aortic erosive lesion by pedicle screw without screw removal.

Methods: A breast cancer patient had a pathological fracture on T10, with spinal cord compression, and a pseudoaneurysm of the aorta in contact with an anterolateral pedicle screw. Endovascular surgery corrected the aortic lesion and allowed decompression, a week later, by posterior arthrodesis (T7-L1), with screw maintenance.

Results: There was no contrast leakage at thorax angiotomography in 2 years, and she died of meningeal carcinomatosis.

Conclusion: Screw maintenance was safe in the endovascular treatment of aortic lesion by erosion.
