BACKGROUND AND PURPOSE Cerebral bypass grafts may develop generalized graft narrowing or focal stenosis during the perioperative period or later. Endovascular techniques such as PTA and stent placement of graft vessels are potential treatment options. Our objective was to review the safety, indications, technique, and results of endovascular management of graft problems. MATERIALS AND METHODS...

A 51-yr-old man presented exertional dyspnea as a consequence of iliocaval fistula combined with paradoxical pulmonary embolism and high-output heart failure. Endovascular stent-graft repair was performed to cover iliocaval fistula and restore the heart function. After the procedure, dyspnea was improved and procedure related complication was not seen. A 6-month follow-up computed tomography sh...

OBJECTIVE To assess the therapeutic outcome after endovascular repair of iliac arterial lesions (IALs) using a self-expandable Nitinol stent graft system. METHODS Between July 2006 and March 2013, 16 patients (13 males, mean age: 68 years) with a self-expandable Nitinol stent graft. A total of 19 lesions were treated: nine true aneurysms, two anastomotic aneurysms, two dissections, one arteri...

We report a case of 74-year-old man presenting with a rupture of a thoracic aortic false aneurysm after undergoing conventional total arch replacement for aortic arch aneurysm (62 mm) and endovascular stent placement for descending aortic aneurysm (70 mm). His chief complaints at the present admission were fever and sensation of dyspnea and we put him on a course of antibiotics for stent graft ...

A zone 0 landing thoracic endovascular aortic repair was performed on a 69-year-old man with saccular arch aneurysm. Seven days after the surgery, patient experienced diminished consciousness and lower limb paralysis. Stent graft collapse seen computed tomography scan. Thereafter, underwent total replacement emergency stent removal.

A retrospective single-center review was performed from 2015 to 2020. Six patients were treated for accidental supra-aortic arterial cannulation during central venous catheter insertion. Three punctures due 12F vein catheters. Four had undergone diagnostic duplex ultrasound (DUS) and two computed tomography angiography (CTA). Surgical intervention with direct repair in four common carotid arter...

Dynamic aortic evaluation in planning thoracic endovascular aortic repair (TEVAR) is important to provide optimal stent graft sizing. Static imaging protocols do not consider normal aortic dynamics and may lead to stent graft to aorta mismatch, causing stent graft related complications, such as type I endoleak and stent graft migration. Dynamic imaging can assist in accurate stent graft selecti...

PURPOSE To review the author's early experience with stent grafts to repair hemodialysis graft-related pseudoaneurysms. MATERIALS AND METHODS Eleven patients had undergone insertion of a stent graft to repair a pseudoaneurysm arising from a PTFE hemodialysis graft. The study group consists of seven women and four men with a mean age of 50.7 years. The primary indications for stent graft place...

PURPOSE To describe the initial use of an off-the-shelf fenestrated stent-graft system for endovascular repair of juxtarenal abdominal aortic aneurysms. TECHNIQUE The off-the-shelf Ventana fenestrated stent-graft system consists of a 25-mm IntuiTrak self-expanding bifurcated stent-graft implanted at the aortic bifurcation. A Ventana self-expanding fenestrated proximal extension stent-graft is...

Thoracic aortic aneurysms and dissections can lead to devastating complications and eventually to premature death. A diseased segment of the aorta has traditionally been replaced with a surgical prosthesis. Open surgery is, unfortunately, associated with relatively high mortality and morbidity. Stent graft treatment was introduced on the side of open surgery 20 years ago, and there have been hi...
