Escalation of Antithrombotic Therapy Should Be Considered in the Presence of Intraluminal Prosthetic Graft Thrombus Following Endovascular Aneurysm Repair.

Objectives: Intraluminal prosthetic graft thrombus (IPT) following Endovascular Aneurysm Repair (EVAR) can have serious consequences. The aim of this study was to assess the prevalence of IPT and to identify the risk factors for its formation and progression.

Methods: This was a retrospective study of 258 patients who had EVAR between 2015 and 2018.

Endovascular repair of aortic arch false aneurysm with branched endograft.

This case report describes the use of a customized branched device for the treatment of a distal anastomotic false aneurysm in an ascending to descending interposition graft in a 34-year-old Jehovah's Witness with congenital aortic arch interruption. A single branched customized stent graft device was used to successfully exclude the false aneurysm. The procedure was challenging due to the abnormal congenital anatomy.

Contralateral occlusion of the internal carotid artery increases the risk of patients undergoing carotid endarterectomy.

Background: Controversy exists about whether occlusion of the contralateral internal carotid artery in patients undergoing carotid endarterectomy (CEA) is associated with a worse perioperative prognosis and outcome.

Methods: A systematic review of electronic information sources was undertaken to identify studies comparing perioperative and early outcomes of CEA in patients with occluded and patent contralateral carotid arteries. The methodologic quality of selected studies was independently appraised by two reviewers.

A "Christmas tree" band for the treatment of arteriovenous dialysis access-related steal syndrome.

Background: Dialysis access steal syndrome (DASS) is an uncommon but often debilitating complication of dialysis access formation. We present a technical description of a novel arteriovenous fistula (AVF) banding technique for the treatment of DASS and the results of a short case series.

Methods: A polyethylene terephthalate carotid patch is shaped with a slit at 1 end and saw tooth edges (resulting in a "Christmas tree" shape) so as to provide a ratchet mechanism to progressively constrict the draining vein of the AVF.

Endovascular aneurysm repair of tuberculous mycotic abdominal aortic aneurysm on a patient with renal transplant.

The case report describes a gentleman with renal transplant who presented with pulmonary tuberculosis (TB) and mycotic aneurysm of abdominal aorta. The aneurysm was successfully treated with endovascular aneurysm repair. A multidisciplinary approach with renal physicians and infectious diseases unit was necessary to treat TB and maintain immunosuppression.

A meta-analysis of outcomes of endovascular abdominal aortic aneurysm repair in patients with hostile and friendly neck anatomy.

Background: An increasing number of abdominal aortic aneurysms with unfavorable proximal neck anatomy are treated with standard endograft devices. Skepticism exists with regard to the safety and efficacy of this practice.

Methods: A systematic review of the literature was undertaken to identify all studies comparing the outcomes of endovascular aneurysm repair (EVAR) in patients with hostile and friendly infrarenal neck anatomy.

Antiphospholipid syndrome presenting with acute digital ischaemia, avascular necrosis of the femoral head and superior mesenteric artery thrombus.

This case illustrates a rare and unique case of a 73-year-old woman who presents with a rapidly developing digital ischaemia, superior mesenteric artery thrombus with positive-lupus anticoagulant. She then developed avascular necrosis of the femoral head. Discussion of the process of diagnosis and management of antiphospholipid syndrome and catastrophic antiphospholipid syndrome are reported.

Hypoplastic internal carotid artery stenosis with a low-lying carotid bifurcation causing cerebral ischemia.

Congenital abnormalities of the internal carotid artery (ICA) are infrequent and can be associated with aberrations of the Circle of Willis. A 47-year-old gentleman presented with transient neurological symptoms and cerebral infarction and carotid Doppler showed a stenotic right ICA. Subsequent computed tomographic angiography showed a hypoplastic ICA with a low-lying bifurcation at the C6 level and aplasia of the anterior communicating artery.

Early results with the use of heparin-bonded stent graft to rescue failed angioplasty of chronic femoropopliteal occlusive lesions: TASC D lesions have a poor outcome.

Purpose: To evaluate early patency rate of the heparin-bonded stent grafts in atherosclerotic long femoropopliteal occlusive disease, and to identify factors that affect outcome.

Methods: Heparin-bonded Viabahn stent grafts were placed in 33 limbs in 33 patients during 2009-2010. The stents were deployed to rescue failed conventional balloon angioplasty.

Superior mesenteric artery pseudoaneurysm associated with celiac axis occlusion treated using endovascular techniques.

The case of a 30-year-old woman with a post-traumatic pseudoaneurysm of the superior mesenteric artery and associated celiac axis occlusion is presented. The patient was successfully treated with celiac artery recanalization and placement of a covered stent within the superior mesenteric artery. Follow-up at 3, 6, and 12 months and 3 years demonstrated patency of the covered stent and continued exclusion of the aneurysm.
