PURPOSE To review the published outcomes of aortic endograft infection treated with preservation of the stent-graft. METHODS An extensive electronic health database search was undertaken to identify all articles published up to May 2013 that reported endograft infection after endovascular aneurysm repair (EVAR) in which treatment included preservation of(More)
OBJECTIVE Patients with juxtarenal, pararenal, or thoracoabdominal aneurysms require complex surgical open repair, which is associated with increased mortality and morbidity. The "chimney graft" or "snorkel" technique has evolved as a potential alternative to fenestrated and side-branched endografts. The purpose of this study is to review all published(More)
BACKGROUND Infected femoral artery pseudoaneurysm (IFAP) is a severe complication in parenteral drug abusers, with difficult and controversial management. Ligation alone without revascularization is frequently associated with later intermittent claudication and limb amputation. Furthermore, arterial reconstruction with a synthetic or venous conduit is(More)
We report a case of postarthroscopic popliteal artery pseudoaneurysm (PSA) with arteriovenous fistula (AVF; PSA-AVF) in a 53-year-old woman who presented with limb edema, pain, and bruit 1 year after arthroscopic meniscectomy. She was treated percutaneously by covered stent deployment. After 6 months of follow-up, the patient was asymptomatic, with patency(More)
BACKGROUND/AIMS Limb-threatening ischemia in patients with end-stage renal disease (ESRD) represents a challenging therapeutic problem. Furthermore, diabetes mellitus is frequently associated with ischemic gangrene, persistent infection and impaired wound healing. The present study was undertaken to examine graft patency, limb salvage and survival in(More)
The most dramatic shift in the management of abdominal aortic aneurysms (AAAs) occurred in 1991, when the first endovascular AAA repair was reported. Endovascular aneurysm repair has revolutionized the treatment of infrarenal AAAs. In the last few years, the companies have developed renewed models of grafts and have modified delivery systems tending to make(More)
OBJECTIVE Most arteriovenous hemodialysis grafts fail ≤18 months after implantation, most commonly due to intimal hyperplasia at the venous anastomosis. This open prospective study compared balloon angioplasty vs nitinol stent placement in the treatment of venous anastomotic stenosis after thrombectomy of prosthetic brachial-axillary accesses. METHODS(More)
AIM The ipsilateral external carotid artery (ECA) can potentially provide an important collateral pathway for cerebral blood flow in the presence of occlusion or severe stenosis of the internal carotid artery (ICA), recovering up to 15% of the middle cerebral arterial flow. The aim of the study is to elucidate the role of ECA in cerebral flow of patients(More)
According to the current international guidelines, patients with infrarenal or juxtarenal abdominal aortic aneurysms (AAAs) measuring > or = 5.5 cm should undergo repair to reduce the risk of rupture. The 5.5-cm-diameter threshold is the size when the AAA rupture rate balances the mortality rates of elective open surgical AAA repair (3%). Endovascular AAA(More)
Mural thrombus formation within aortic endoprostheses has been described to occur in up to one-third of aortic endografts depending on the device type. Data regarding the clinical significance of such a phenomenon are scarce, but in most cases it is considered to be clinically innocent. The authors describe a rare case of late renal artery occlusion due to(More)
