The influence of narrow aortic bifurcation on limb graft patency: a two-center retrospective study.

Background: Narrow aortic bifurcation (NAB) has been considered as a potential risk factor for graft limb thrombosis after endovascular aortic repair (EVAR). The aim of this study was to compare mid- and long-term outcome of EVAR in patients with NAB and standard aortic bifurcation (SAB).

Methods: Data from patients receiving EVAR were prospectively collected and retrospectively analyzed.

Treatment of ruptured subclavian steal flow-related vertebrobasilar junction aneurysms: Case report on surgical and endovascular considerations from two cases.

Introduction: Subclavian steal phenomenon causes retrograde flow through the vertebral artery, ipsilateral to the affected subclavian artery, which rarely leads to flow-related vertebrobasilar junction (VBJ) aneurysms.

Case Descriptions: We describe two cases of subarachnoid hemorrhage from such ruptured aneurysms in which the retrograde flow direction in the vertebral artery complicated surgical and endovascular treatment.

Discussion: Reversed flow in the vertebral artery, ipsilateral to the stenotic subclavian artery leads to a lack of proximal control in surgical clipping of these VBJ aneurysms and jeopardizes stability of coil and stent placement in endovascular aneurysm treatments in this setting.

Late hematogenous seeding and infection of a femoropopliteal Omniflow II bypass.

Introduction: Omniflow II is promoted as an infection-resistant vascular graft. It is used to treat vascular graft infection; nevertheless, early graft infection has been reported.Report: A 71-year-old patient was treated with an Omniflow II bypass for a non-healing diabetic foot ulcer.

Predictive Factors of Operative Need in Medically Managed Type B Aortic Dissections.

Background: Aneurysmal degeneration of medically managed type B aortic dissection (TBAD) can be a life-threatening condition. Preventive thoracic endovascular aorta repair (TEVAR) in patients at risk could potentially be beneficial. The aim of this study was to examine the predictors for late aneurysmal dilatation after TBAD.

A Case of Primary Aortoenteric Fistula: Review of Therapeutic Challenges.

Backgrounds: Primary aortoenteric fistula (PAEF) is a lethal cause of gastrointestinal bleeding. They mainly originate from eroding abdominal aortic aneurysms into the intestinal wall. Other known causes involve malignancies, infection, corpora aliena, or radiation therapy.

A ruptured omental aneurysm, a rare cause of intraabdominal bleeding.

Of all splanchnic artery aneurysms, the omental artery aneurysm is the most uncommon. In the published literature, there is no report of an incidental diagnosis, and all were discovered only after rupture. Until now, this is only the sixth case of a ruptured omental aneurysm published, and the first case with a concomitant nonruptured omental aneurysm.

Long-term results after endovascular abdominal aortic aneurysm repair using the Cook Zenith endograft.

Objective: This study assessed the long-term outcome of patients with abdominal aortic and aortoiliac aneurysms treated with the Cook Zenith endovascular graft (Cook Inc, Bloomington, Ind).

Methods: Between September 1998 and October 2003, 143 patients underwent elective endovascular aneurysm repair (EVAR) using the Cook Zenith endograft. Data from these patients were reviewed from a prospective database in October 2008.

Transcatheter embolization of a type II endoleak after hybrid repair for thoracoabdominal aortic aneurysm.

Hybrid stent-graft procedures with visceral revascularization have been reported as an alternative treatment option for thoracoabdominal aortic aneurysms (TAAAs), although the potential advantages of reduced morbidity and mortality compared with open surgical repair have not been definitively demonstrated. Endovascular aneurysm repair is associated with endoleaks in as many as 20% of cases in some series, often requiring repeat intervention. In the present case, during follow-up after a hybrid TAAA repair, a patient developed a type II endoleak originating from a celiac artery that was not ligated at its origin.

Esophageal necrosis after endoprosthesis for ruptured thoracoabdominal aneurysm type I: can long-segment stent grafting of the thoracoabdominal aorta induce transmural necrosis?

Background: To study the pathophysiology of esophageal necrosis after endoprosthesis was performed for a ruptured aneurysm and to define preventive measures and possible treatment options.

Method: A 72-year-old man with thoracoabdominal aneurysm type I and dysphagia underwent an emergent carotico-carotid bypass in combination with thoracic endovascular aortic aneurysm repair starting at a point distal to the brachiocephalic trunk and ending proximal to the superior mesenteric artery. On day 12, a decortication was performed for treating an infection in the remaining hematoma.

Paraparesis after thoracic stent-graft relining for an unrecognized type III endoleak.

Background: We examined the reasons for missing a type III endoleak on conventional imaging and the pathophysiology of paraparesis after relining this stent graft.

Methods And Results: A 46-year-old man was treated with a thoracic stent graft for thoracic rupture of a chronic type B thoracoabdominal dissection with aneurysm formation. In a second intervention, retrograde revascularization of the visceral and renal arteries was performed in combination with insertion of an abdominal stent graft.

Endovascular treatment of an iliocaval arteriovenous fistula presenting with multiple organ failure.

Iliocaval arteriovenous fistula is an uncommon, but challenging condition. The most common cause is spontaneous rupture of the iliac artery into the venous system due to aneurismal dilatation. We report a case of iliocaval fistula after previous aortic surgery presenting as acute liver failure as most prominent part of multiple organ failure and successful endovascular repair.

Nitinol stent implantation in long superficial femoral artery lesions: 12-month results of the DURABILITY I study.

Purpose: To evaluate the long-term efficacy and integrity of the PROTEGE EverFlex stent in superficial femoral artery (SFA) lesions in symptomatic patients with peripheral artery disease (PAD).

Methods: A prospective, multicenter, nonrandomized study enrolled 151 subjects (111 men; mean age 67.8 years, range 42-93) undergoing percutaneous treatment of de novo, restenotic, or reoccluded SFA lesions between August 11, 2006, and June 26, 2007.

Heparin-bonded ePTFE grafts compared with vein grafts in femoropopliteal and femorocrural bypasses: 1- and 2-year results.

Objective: Many patients with peripheral arterial occlusive disease who require a lower-limb bypass have no available autologous saphenous vein (ASV) for the procedure and thus require a prosthetic graft. Expanded polytetrafluoroethylene (ePTFE) grafts are commonly used, but results with these prostheses have varied, especially when the distal anastomosis is below the knee. However, there is increasing evidence that ePTFE grafts to which heparin has been bound with use of covalent endpoint linkage provide better results.

The role of thrombolysis in acute infrainguinal bypass occlusion: a prospective nonrandomized controlled study.

Current treatment of acute infrainguinal bypass occlusion consists of either surgical revascularization or catheter-guided intra-arterial thrombolysis with adjunctive correction of the underlying flow-limiting lesion. In maintaining long-term patency, improving the number of outflow vessels could be of utmost importance. To compare the efficiency of both thrombolysis and primary surgical revascularization and to study the effect of thrombolysis on the number of patent outflow vessels, a prospective nonrandomized study was performed.

Stent-graft repair of a mycotic ascending aortic pseudoaneurysm.

A 75-year-old woman with a history of coronary artery bypass surgery complicated by mediastinitis presented with hemoptysis and fever. An enlarging pseudoaneurysm of the ascending aorta was found on computed tomography (CT) and magnetic resonance imaging. After a bypass graft procedure for cerebral and cardiac protection, two endoprosthetic cuffs, which are normally used for proximal abdominal aortic stent-graft extension, were positioned over the pseudoaneurysm neck via right carotid artery access.

Thrombospondin-1 controls vascular platelet recruitment and thrombus adherence in mice by protecting (sub)endothelial VWF from cleavage by ADAMTS13.

The function of thrombospondin-1 (TSP-1) in hemostasis was investigated in wild-type (WT) and Tsp1-/- mice, via dynamic platelet interaction studies with A23187-stimulated mesenteric endothelium and with photochemically injured cecum subendothelium. Injected calcein-labeled WT platelets tethered or firmly adhered to almost all A23187-stimulated blood vessels of WT mice, but Tsp1-/- platelets tethered to 45% and adhered to 25.8% of stimulated Tsp1-/- vessels only.

Gallic acid antagonizes P-selectin-mediated platelet-leukocyte interactions: implications for the French paradox.

Background: Current paradigm attributes the low incidence of cardiovascular disorders in Mediterranean countries despite a high saturated fat intake, the "French paradox," to the antioxidant capacity of red wine polyphenols. Conceivably, other antiinflammatory pathways may contribute to at least a similar extent to the atheroprotective activity of these polyphenols. We have investigated whether gallic acid (GA), an abundant red wine polyphenol, modulates the activity of P-selectin, an adhesion molecule that is critically involved in the recruitment of inflammatory cells to the vessel wall and thus in atherosclerosis.
