Endovascular Treatment of Popliteal Artery Aneurysms Has Comparable Long-Term Outcomes to Open Repair with Shorter Length of Stay.

J Vasc Surg 2021 May 3. Epub 2021 May 3.

Division of Vascular and Endovascular Surgery, Department of Surgery, NYU Langone Health, New York, NY. Electronic address:

Objective: Over the past two decades, the treatment of popliteal artery aneurysms (PAAs) has undergone a transformation. While open surgical repair (OR) remains the gold standard for treatment, endovascular repair (ER) has become an attractive alternative in select patient populations. The objective of this study was to compare the outcomes of open versus endovascular repair of PAAs at a single institution. Read More

Anatomic Eligibility for Endovascular Aneurysm Repair Preserved Over Two Years of Surveillance.

J Vasc Surg 2021 May 3. Epub 2021 May 3.

School of Medicine and Public Health, Division of Vascular Surgery, University of Wisconsin.

Objective: Endovascular aneurysm repair (EVAR) is a widely used option for patients with suitable vascular anatomy who have a large infrarenal abdominal aortic aneurysm (AAA). Patients with small AAAs are managed with careful surveillance and it is a common concern that their anatomy may change with AAA growth, and their option for EVAR may become limited. Device innovation has resulted in expanded ranges of anatomy that may be eligible for EVAR. Read More

Proc (Bayl Univ Med Cent) 2021 Jan 11;34(3):391-393. Epub 2021 Jan 11.

Baylor Scott & White, The Heart Hospital - Plano, Plano, Texas.

Renal artery aneurysms (RAAs) are rare and are frequently discovered incidentally during the workup for other renal issues. Open surgery has been a popular approach to managing RAAs; however, endovascular techniques have recently emerged as a less invasive option. Endovascular therapy involves stent angiography and coil embolization of the aneurysm. Read More

Aortic neck IFU violations during EVAR for ruptured infrarenal aortic aneurysms are associated with increased in-hospital mortality.

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

Division of Vascular Surgery and Endovascular Therapy, The Johns Hopkins Medical Institutions, Baltimore, MD, USA.

Objective: Vascular surgeons treating patients with ruptured abdominal aortic aneurysm (rAAA) must make rapid treatment decisions and sometimes lack immediate access to endovascular devices meeting the anatomic specifications of the patient at hand. We hypothesized that endovascular treatment of rAAA (rEVAR) outside manufacturer instructions-for-use (IFU) guidelines would have similar in-hospital mortality compared to patients treated on-IFU or with an infrarenal clamp during open repair (rOAR).

Methods: Vascular Quality Initiative (VQI) datasets for endovascular and open aortic repair were queried for patients presenting with ruptured infrarenal AAA between 2013-2018. Read More

Dual-energy Computed Tomography Delayed Myocardial Enhancement in the Diagnostic Dilemma of True versus False Left Ventricular Aneurysm - A Case Report.

J Clin Imaging Sci 2021 16;11:20. Epub 2021 Apr 16.

Department of Cardiology and Angiology, National Institute for Cardiovascular Diseases, Bratislava, Slovakia, Europe.

The aim of this case report is to show the capability of cardiac computed tomography (CT) in combination with dual-energy CT (DECT) delayed myocardial enhancement to support diagnostic decision making in the complicated differential diagnosis of true versus false left ventricle (LV) aneurysm, as well as provide additional information that can influence overall patient outcome. We present a 71-year-old obese patient with metabolic syndrome, stable chronic coronary syndrome with three-vessel disease, and recent chest discomfort. His coronary angiogram showed no significant coronary artery stenosis, but suspicion of LV apical pseudoaneurysm was expressed. Read More

Commentary on Post, . Ultra-early tranexamic acid after subarachnoid hemorrhage: A randomized controlled trial. Lancet 2021.

Surg Neurol Int 2021 14;12:156. Epub 2021 Apr 14.

Department of Surgery, Division of Neurosurgery, Queen Mary Hospital, University of Hong Kong, Hong Kong.

Background: Tranexamic acid (TA) administration in aneurysmal subarachnoid hemorrhage (SAH) within the first 24 hours may reduce the incidence of early aneurysmal rebleeding. However, this is also the potential for an increased risk of delayed cerebral ischemia if TA is administered for more than 72 hours following the initial aneurysmal rupture.

Development of experimental ground truth and quantification of intracranial aneurysm pulsation in a patient.

Sci Rep 2021 May 3;11(1):9441. Epub 2021 May 3.

Laboratory of Experimental Medecine (ULB 222 Unit), Medicine Faculty, Université Libre de Bruxelles, CHU de Charleroi, 6110, Montigny-le-Tilleul, Belgium.

Aneurysm wall motion has been reported to be associated with rupture. However, its quantification with medical imaging is challenging and should be based on experimental ground-truth to avoid misinterpretation of results. In this work a time-resolved CT angiography (4D-CTA) acquisition protocol is proposed to detect the pulsation of intracranial aneurysms with a low radiation dose. Read More

Impact of frailty on acute outcomes of endovascular thoracic and abdominal aneurysm repair.

Surgery 2021 Apr 30. Epub 2021 Apr 30.

Cardiovascular Outcomes Research Laboratories (CORELAB), Division of Cardiac Surgery, Department of Surgery, University of California, Los Angeles, CA. Electronic address:

Background: While coding-based frailty tools may readily identify at-risk patients, they have not been adopted into screening guidelines for endovascular abdominal aortic aneurysm repair or thoracic endovascular aortic repair at the national level. We aimed to characterize the impact of frailty on clinical outcomes and resource use after endovascular aneurysm repair and thoracic endovascular aortic repair using a nationally representative cohort.

Methods: The 2005 to 2018 National Inpatient Sample was queried to identify all adults undergoing elective endovascular abdominal aortic aneurysm repair or thoracic endovascular aortic repair. Read More

Transcavernous Resection of an Upper Clival Chondrosarcoma: "Cavernous Sinus as a Route": 2-Dimensional Operative Video.

Oper Neurosurg (Hagerstown) 2021 May 3. Epub 2021 May 3.

Department of Neurosurgery, Brigham and Women's Hospital, Harvard Medical School, Boston, Massachusetts, USA.

Complete resection of skull base chondrosarcomas offers the potential for a durable, or even lifelong, cure and is best achieved at the first surgery.1,2 When a skull base chondrosarcoma is located at the upper clivus and in the interpeduncular cistern and invading laterally toward the petrous apex and cavernous sinus, the traditional approaches, ie, endonasal endoscopic or middle fossa approaches, are not adequate for the exposure and resection. The transcavernous sinus approach has been utilized to remove tumor from the cavernous sinus and as a corridor to the interpeduncular cistern and upper clivus, originally described for the clipping of basilar apex aneurysms.
