Popliteal artery entrapment syndrome: a case report with literature review.

Pan Afr Med J 2021 27;39:80. Epub 2021 May 27.

Department of Vascular Surgery, Mohammed VI University Hospital, Mohammed First University of Oujda, Oujda, Morocco.

Popliteal artery entrapment syndrome generally causes calf claudication in young active adult. It is resulting of the anatomical relationship between the popliteal artery and adjacent muscles or fibrous bands in the popliteal fossa. We present the case of a 36-year-old male with left calf claudication limb in whom popliteal artery entrapment syndrome was diagnosed, and successfully treated surgically.

Sacciform aneurysm of the right common iliac artery in Behcet's disease treated with EVAR: Case report.

Int J Surg Case Rep 2021 Aug 7;85:106172. Epub 2021 Jul 7.

Mohammed First University, Faculty of Medicine and Pharmacy, Oujda, Morocco; University Hospital Center Mohamed VI, Oujda, Morocco.

Introduction: Behcet's disease is a systemic vasculitis with vascular tropism usually manifested by phlebitis. Arterial manifestations are rare, most often result in aneurysms than occlusions. The objective of this article, is to relate our experience and pretherapeutic reasoning for the indication of an endovascular treatment of an atypical sacciform iliac aneurysm, in an elderly patient followed for Behcet's disease.

Case Report: This is a 73-year-old patient, followed for Behcet's disease under immunosuppressive treatment and corticosteroids treatment, admitted to our structure, for the surgical management of an aneurysm of the right common iliac artery diagnosed by computed tomographic angiography performed for chronic paroxysmal abdominal pain, treated by EVAR after a multidisciplinary discussion, complicated by a thrombosis of the left leg of the bifurcated aortic stent graft the, managed by performing an extra anatomical bypass, complicated late by the appearance of a Scarpa hematoma, who was evacuated.

Discussion: Behcet's disease is a systemic vasculitis with vascular tropism, usually affecting young. Our case is an elderly subject, whose diagnosis and follow-up of Behcet's disease is recent and whose discovery of this aneurysm was fortuitous, after performing a CT angiogram required for another reason. The objective of this article, is to relate our experience and pre-therapeutic reasoning for theindication of an endovascular treatment, and our management of the complications.

Conclusion: Endovascular treatment of iliac sacciform aneurysm by placing a covered stent is a good alternative to conventional surgery with fewer complications; especially in front of a field of Behcet's disease.

Endovascular treatment of a ruptured post-traumatic false aneurysm of the aortic isthmus: A case report.

Int J Surg Case Rep 2021 Aug 9;85:106190. Epub 2021 Jul 9.

Mohammed First University, Faculty of Medicine and Pharmacy, Oujda, Morocco; University Hospital Center Mohamed VI, Oujda, Morocco.

Introduction: The false aneurysm of the aortic isthmus is, given its severity and case fatality rate, a subject of interest in vascular surgery. The interest of this article is the analysis of the different characteristics of this pathology based on the study of a case report and on a review of the literature.

Case Report: This is a 21-year-old patient admitted for the management of a severe polytrauma following a fall from a cliff, causing him paraplegia following a fracture of the dorsal spine which is objectified on the CT bodyscan, which also shows the presence of a localized dissection with ruptured false aneurysm of the isthmus. After emergency conditioning and initial neurosurgical management by vertebral osteosynthesis, the postoperative effects are aggravated by the occurrence of a bilateral massive pulmonary embolism. Thus, given the high risk of complications or death following classic thoracotomy surgery, we decided to carry out endovascular treatment by placing a covered endoprosthesis.

Discussion: The aortic isthmus false aneurysm is a relatively rare condition that mainly interests the young subject in an often-post-traumatic context. The surgical treatment represented by thoracotomy, which, in addition to being invasive, exposes the patient to multiple complications as disabling as each other. All of these elements explain the advantage of endovascular treatment, which is much less invasive with a better prognosis.

Conclusion: The therapeutic management of a pseudoaneurysm of the isthmus is undergoing constant development; endoprostheses currently occupy the place of choice in the treatment of these lesions.

Multiple paradoxical embolisms revealing a patent foramen ovale in a patient with deep venous thrombosis: A case report.

Ann Med Surg (Lond) 2021 Jun 28;66:102426. Epub 2021 May 28.

Department of Vascular Surgery, Mohammed VI University Hospital of Oujda, Mohammed First University of Oujda, Morocco.

Introduction: Paradoxical embolism is a rare medical phenomenon. Depending on the site of embolisation, it can cause different symptoms. Although rare, mesenteric ischemia can reveal paradoxical embolism, and the embolisation of two different sites is rarely described in the literature.

Case Presentation: We report the observation of a patient with a table associating an acute mesenteric ischemia and an acute ischemia of the upper limb; whose the etiological assessment revealed a deep venous thrombosis of the lower limbs complicated by pulmonary embolism.

Clinical Discussion: These paradoxical embolisms occurred through a patent foramen ovale. The diagnosis of the patent foramen ovale in this patient was revealed by transthoracic echocardiography, with bubble test. The patient benefited from an embolectomy of the superior mesenteric artery and an embolectomy using fogarty catheter by approching humeral artery at the elbow crease with good postoperative evolution. The patient was put on long-term anticoagulation with Acenocoumarol (because of low socio-economic level of our patient). We didn't recommended the closure of the PFO because of the small size of the shunt and especially because the patient refuses that procedure.

Conclusion: Paradoxical embolism remains a pathology rarely mentioned by clinicians, although it can engage the functional and vital prognosis of the patient, hence the interest of a good cardiac evaluation in any patient with embolic ischemia.

Concomitant acute limb ischemia and multiple acute ischemic strokes complicating COVID-19: a case report.

Pan Afr Med J 2021 17;38:275. Epub 2021 Mar 17.

Department of Cardiology, Mohammed VI University Hospital, Faculty of Medicine and Pharmacy of Oujda, Oujda, Morocco.

Since the spread of the coronavirus disease 2019 (COVID-19) pandemic, cardiovascular complications are interestingly increasing, particularly thrombotic events, especially in those requiring intensive care. Venous thromboembolism is well known to occur in patients infected by the SARS-CoV-2, but only a few arterial thromboembolism cases have been previously reported. Herein, we report the case of a COVID-19 complicated by a concomitant acute right limb ischemia and multiple acute ischemic strokes. This rare case emphasizes the hypercoagulable state described in COVID-19 patients and the need for anticoagulation therapy to prevent these severe complications.

Acute Abdominal Compartment Syndrome complicating a chronic mesenteric ischemia revascularization.

Int J Surg Case Rep 2021 Apr 20;81:105801. Epub 2021 Mar 20.

Vascular Surgery Department, Mohammed VI University Hospital Center, Oujda, Morocco; Mohammed 1st University, Faculty of Medicine and Pharmacy of Oujda, Morocco. Electronic address:

Background: Abdominal Compartment Syndrome (ACS) is a pathological condition that results from an increase in pressure within the abdomen associated with organ failure. It can be acute or chronic, primary or secondary. ACS poses a serious diagnostic challenge for physicians as the clinical presentation is varied and can mimic other medical pathologies. To prevent a multi-organ failure and ultimately death due to this disease, the World Society of Abdominal Compartment Syndrome (WSACS) suggested clinical criteria and biology tests to facilitate an early diagnosis of acute ACS.

Case Presentation: We report a case of 61 year-old man diagnosed with chronic mesenteric ischemia that has been successfully treated by prosthetic bypass. The postoperative period was eventual, the patient presented complications corresponding essentially to a manifest acute ACS. The treatment consisted on abdominal decompression and resuscitation measures.

Conclusions: An early diagnosis of ACS disease for an appropriate therapeutic initiation is mandatory to prevent its complications and save the patient's life prognosis.

Morocco's First Biobank: Establishment, Ethical Issues, Biomedical Research Opportunities, and Challenges.

Biomed Res Int 2020 8;2020:8812609. Epub 2020 Dec 8.

Department of Psychiatry, Mohammed VI University Hospital, Faculty of Medicine and Pharmacy, University Mohammed Premier, Oujda, Morocco.

Background: Biobanks are highly organized infrastructures that allow the storage of human biological specimens associated with donors' personal and clinical data. These infrastructures play a key role in the development of translational medical research. In this context, we launched, in November 2015, the first biobank in Morocco (BRO Biobank) in order to promote biomedical research and provide opportunities to include Moroccan and North African ethnic groups in international biomedical studies. Here, we present the setup and the sample characteristics of BRO Biobank.

Methods: Patients were recruited at several departments of two major health-care centers in the city of Oujda. Healthy donors were enrolled during blood donation campaigns all over Eastern Morocco. From each participant, personal, clinical, and biomedical data were collected, and several biospecimens were stored. Standard operating procedures have been established in accordance with international guidelines on human biobanks.

Results: Between November 2015 and July 2020, 2446 participants were recruited into the BRO Biobank, of whom 2013 were healthy donors, and 433 were patients. For healthy donors, the median age was 35 years with a range between 18 and 65 years and the consanguinity rate was 28.96%. For patients, the median age was 11 years with a range between 1 day and 83 years. Among these patients, 55% had rare diseases (hemoglobinopathies, intellectual disabilities, disorders of sex differentiation, myopathies, etc.), 13% had lung cancer, 4% suffered from hematological neoplasms, 3% were from the kidney transplantation project, and 25% had unknown diagnoses. The BRO Biobank has collected 5092 biospecimens, including blood, white blood cells, plasma, serum, urine, frozen tissue, FFPE tissue, and nucleic acids. A sample quality control has been implemented and suggested that samples of the BRO Biobank are of high quality and therefore suitable for high-throughput nucleic acid analysis.

Conclusions: The BRO Biobank is the largest sample collection in Morocco, and it is ready to provide samples to national and international research projects. Therefore, the BRO Biobank is a valuable resource for advancing translational medical research.

Cutaneous necrosis of the arteriovenous fistula puncture site in chronic hemodialysis: A historical complication or an ever-present threat? A series of 26 cases.

Hemodial Int 2021 01 1;25(1):29-34. Epub 2020 Oct 1.

Vascular Surgery Unit, University Hospital Mohammed VI, Oujda, University Mohammed First, Oujda, Morocco.

Introduction: Cutaneous necrosis (CN) at the puncture site of the arteriovenous fistula (AVF) in chronic hemodialysis (CHD) is a rare but potentially fatal complication. The objective of our work was to establish the associated complications, vascular prognosis, and patient survival of CHD patients presenting cutaneous necrosis.

Methods: This retrospective study (January 2016 to March 2020) was conducted in the Department of Vascular Surgery and the Department of Nephrology at the University Hospital Center Mohammed VI of Oujda, Morocco. Included were all CHD patients admitted for treatment of cutaneous necrosis at the puncture site of a native AVF.

Results: Data from 26 cases were collected. The mean age was 58.7 ± 16 years, 70.8% were female, and 25% had diabetic nephropathy; 42.3% of the AVFs were radiocephalic and 46.1% were brachiocephalic; 42.2% of patients presented active bleeding, of whom 91% required a blood transfusion; 80.8% of the AVFs were complicated by aneurysms. Fistulography showed stenosis in 42.3% of cases. Urgent surgical intervention was performed on all the patients. Fifty percent of patients required placement of a short-term hemodialysis catheter. Two patients had presented a recurrence. Death occurred in one case following a massive hemorrhagic shock.

Conclusion: Cutaneous necrosis is a relatively common complication and requires early screening and immediate surgical intervention.

Tuberculosis of the renal artery: a rare cause of renovascular arterial hypertension.

Ann Vasc Surg 2009 Nov-Dec;23(6):786.e7-9

Service de Chirurgie Vasculaire, Hôpital Ibn Sina, CHU de Rabat, Rabat, Morocco.

Tuberculosis is an endemic disease in Morocco. Main blood vessels are rarely affected; the few mentioned cases are aneurysmal. We report a 17-year-old patient presenting with renovascular arterial hypertension, revealed thanks to the discovery of an occlusion of the right renal artery in Duplex scan. During the intervention, the observation of pararenal and mesenteric tuberculous polyadenopathy let us suggest the same kind of lesion at the level of the occluded renal artery. Once antituberculosis treatment had been carried out, the right renal artery was revascularized with a right iliorenal bypass using reversed internal saphenous vein. The postoperative course was uneventful, with an 18-month follow-up. Arterial pressure was normal without antihypertensive treatment, and the bypass was patent. As far as we know, this is the first case of renovascular arterial hypertension resulting from tuberculosis treated with an iliorenal bypass.

[Hepatic artery aneurysm].

Presse Med 2008 May 4;37(5 Pt 1):793-6. Epub 2008 Mar 4.

Service de chirurgie vasculaire, Hôpital Ibn Sina, Rabat, Maroc.

Introduction: Aneurysms of the hepatic artery are relatively rare. Diagnosis often occurs only after rupture, and mortality is substantial. We report two new cases.

Cases: The first patient was a 70-year-old woman whose asymptomatic aneurysm of the common hepatic artery was identified during ultrasound for vomiting and abdominal pain. Open aneurysm repair and a hepatosplenic bypass led to a favorable outcome. The second patient was a 54-year-old man; his right hepatic artery aneurysm was diagnosed after it ruptured in the gall bladder.

Discussion: We review the literature about hepatic artery aneurysms and discuss the clinical features and methods for diagnosis and treatment of these uncommon lesions.
