BACKGROUND AND OBJECTIVES The renin-angiotensin-aldosterone system has been implicated in the pathogenesis of neointimal hyperplasia, and a role for angiotensin II in the migration and proliferation of vascular smooth muscle cells in restenotic lesions has been proposed. The aim of this study was to determine the anti-proliferative and anti-inflammatory effects of ramiprilat-coated stents in a ...

An 86-year-old man with a 75-mm TAA that terminated just above the celiac artery was treated with a customized Zenith stent graft that had a distal fenestration for the superior mesenteric artery (SMA). Because angiography demonstrated a type IB endoleak, an additional extension stent graft was deployed, and coil embolization of the aneurysmal sac was performed. Three months later, there was no...

The patient was a 64-year-old man. He developed fever and lumbago 6 months after the EVAR. Because CT showed an abscess in the aortic aneurysm surrounding the stent graft, stent-graft infection was diagnosed, and treatment with intravenous antibiotics was initiated. However, the fever and inflammatory markers persisted; therefore, CT-guided drainage catheter placement was performed. After all t...

BACKGROUND Although the left subclavian artery (LSA) is simply covered to exclude distal aortic arch aneurysm during endovascular stent-grafting, this technique is potentially harmful. METHODS AND RESULTS Between January 2001 and April 2005, 40 cases of stent-grafting were performed for distal aortic arch diseases. For all 31 elective cases, the LSA occlusion test using a balloon catheter was...

BACKGROUND Fast post-implantation stent endothelialization is desirable for theoretically reducing the possibility of stent thrombosis. OBJECTIVE To evaluate the extent of sirolimus-eluting stent strut endothelialization (delivered from the luminal and abluminal aspects or abluminal aspect only) in the iliac arteries of rabbits. METHODS The iliac arteries of 10 rabbits were implanted with f...

a 43-year-old man with liver cirrhosis received transjugular intrahepatic portosystemic shunt (tips) for the treatment of recurrent variceal bleeding and f3 esophageal varices. during routine follow up liver ultrasound examination, six months after the implantation, tips occlusion was suspected and tips revision was performed. during the revision, moderate to severe stenosis at the hepatic veno...

Endovascular stent grafting with different commercially available stent graft systems is widely applied for the treatment of abdominal aortic aneurysms with high success rates in the current era. Various types of endoleaks are potential complications of the procedure. They usually occur in the early period. In this report, we present type 3b endoleak occurring 14 months after a successful endov...

OBJECTIVE We modified the conventional aortic arch replacement procedure to avoid circulation arrest and a prolonged extracorporeal circulation time, especially in cases of acute aortic dissection. We herein present our experience with a modified branch-first approach to acute aortic dissection, with anastomosis of the supra aortic vessels prior to commencing cardiopulmonary bypass. METHODS S...

We present a case of a 14 year old Caucasian male who underwent initially successful endovascular repair of a traumatic injury to the descending thoracic aorta. The patient had undiagnosed Factor V Leiden at the time of the endovascular repair. He later presented with thrombosis of the endovascular stent graft, necessitating open removal of the stent graft and replacement of the involved aorta ...
