Background The aortic arch is wide, compliant, and mobile. Its flow rate is high and its branches supply an organ, the brain, with no tolerance for ischemia. In this location, an endovascular stent graft is difficult to deliver, difficult to secure, and prone to fatigue fracture, graft erosion, or migration. The only advantage is the opportunity for downstream access to vital arterial branches,...

OBJECTIVE To evaluate the effect of temporary stent graft placement in the treatment of benign anastomotic biliary strictures. MATERIALS AND METHODS Nine patients, five women and four men, 22-64 years old (mean, 47.5 years), with chronic benign biliary anastomotic strictures, refractory to repeated balloon dilations, were treated by prolonged, temporary placement of stent-grafts. Four patient...

INTRODUCTION Bilateral common iliac artery (CIA) aneurysm (CIAA) is a rare entity. In the past decade, different endovascular approaches have been adopted for patients with several comorbidities or unfit for open repair (OR). Recently, the use of iliac branch stent graft has been proposed, resulting in satisfactory patency rates and decrease in morbidity. Currently, according to instruction for...

Objective: Two cases in which emergency retrograde stenting were performed for occlusion of the left common carotid artery orifice that occurred during thoracic endovascular aortic repair are reported. Case Presentations: In males in their 70s with thoracic aortic aneurysm, oxygen saturation dropped in the left cerebrum immediately after deployment of the thoracic aortic stent graft under gener...

Open surgery for a type Ib endoleak after thoracic endovascular aortic repair is associated with some knacks and pitfalls, particularly in cases wherein the distal edge of a stent graft is located at just supraceliac aorta and the renovisceral segment and infrarenal aorta do not require surgical intervention. Here we describe the invaginated graft insertion technique to provide an easy and secu...

BACKGROUND Gold is a highly biocompatible material. Experimental evidence suggests that coating the stent with a gold layer may have a beneficial influence. In this randomized trial, we assessed whether gold-coated stents were associated with a better clinical and angiographic outcome after coronary placement. METHODS AND RESULTS Patients with symptomatic coronary artery disease were randomly...

We described a modified technique for implanting a bridging stent-graft into an iliac branched device. A 79-year-old male who had received aortobiiliac synthetic graft surgery for a ruptured abdominal aortic aneurysm six months earlier was admitted to our unit for treatment of a left common iliac aneurysm involving the origin of the hypogastric artery. A standard technique was unsuccessful at i...

background: there have been reports on stent-related vascular erosions about patients with benign or malignant stenosis of the esophagus who received endoscopic stent insertion for palliative intention for oral intake. case presentation: a 61-year-old woman with esophageal cancer located in the middle part of esophagus was treated with esophagectomy. two years following the surgery, malignant s...

The aim of this study was to examine the anti-inflammatory effect of abciximab-coated stent in a porcine coronary overstretch restenosis model. Ten abciximab-coated stents, ten sirolimus-eluting stents (SES), and ten paclitaxel-eluting stents (PES) were deployed with oversizing (stent/artery ratio 1.3:1) in porcine coronary arteries, and histopathologic analysis was done at 28 days after stenti...

To determine the relation of intimal hyperplasia thickness to stent size in nonpolymeric paclitaxel-coated stents, intravascular ultrasound was performed after stent implantation and at 6 months. Similar to bare metal stents, this study demonstrated that intimal hyperplasia thickness is independent of stent size. There was no deleterious effect of the increased concentration associated with usi...
