abdominal aortic coarctation is an extremely rare vascular pathology. its etiology can be congenital or acquired. here we present a case of acquired infrarenal abdominal coarctation in a 66-year-old woman who complained of low back and legs pain. she had no signs of resting lower limb ischemia, with diminished distal pulses and normal blood pressure in upper and lower extremities. magnetic reso...

background the transjugular intrahepatic portosystemic stent-shunt (tipss) builds a shortcut between the portal vein and a liver vein, and represents a sophisticated alternative to open surgery in the management of portal hypertension or its complications. objectives to describe clinical experiences with a low-profile nitinol stent system in tipss creation, and to assess primary and long-term s...

OBJECTIVES Several endoscopic techniques have been proposed for the management of post-sphincterotomy bleeding. Lately, self-expandable metal stents deployment has gained popularity especially as a rescue therapy when other endoscopic techniques fail. METHODS-RESULTS We report the case report of a massive post-sphincterotomy bleeding in a patient with a self-expandable metal stent in the bili...

INTRODUCTION Advanced gastric carcinoma often decreases quality of life because of upper gastrointestinal tract stenosis. Self-expandable metal stents have been thought to be an effective, minimally invasive treatment for stenosis. However, the effectiveness of self-expandable metal stent placement for carcinomatous stenosis of the gastric body and antrum has not been clarified, and there have ...

Implanting a self-expandable stent at the ostium of the common iliac artery (CIA) may lead to coverage of the orifice of the contralateral CIA. Here, we describe a novel application of the culotte stent technique using a balloon-expandable stent to bail out an ostial stenotic legion of a jailed CIA due to prior self-expandable stent placement. The bilateral CIAs were revascularized by culotte s...

BACKGROUND Temporary placement of self-expandable stents has been increasingly used for the management of benign esophageal diseases. OBJECTIVE To evaluate the safety of endoscopic removal of esophageal self-expandable stents placed for the treatment of benign esophageal diseases. DESIGN Multicenter retrospective study. SETTING Six tertiary care centers in the United States and Europe. ...

Although there are still some controversies on the choice of ideal stent as well as balloon-expandable versus self-expanding stents for aorto-iliac disease; iliac stenting is widely accepted procedure for focal atherosclerotic iliac artery stenosis. Herein, we present an unusual unilateral iliac stenting complication caused by disintegration struts of balloon-expandable stent which was successf...

OBJECTIVES The study aimed to evaluate the feasibility of off-pump transapical mitral valve-in-ring implantation and to test the performance of a custom-made self-expandable stent valve, in comparison with the standard SAPIEN valve. METHODS Acute experiments were performed in five pigs. Animals (mean weight 58.4 ± 7.3 kg) underwent mitral valve annuloplasties under cardiopulmonary bypass usin...

Transcatheter treatment of aortic coarctation, with balloon angioplasty or stent implantation, is now an acceptable alternative to surgical repair. However these procedures may result in complications, such as vascular wall injury and re-stenosis of the lesion. A nitinol self-expandable stent, when deployed at the coarctation site, produces low constant radial force, which may result in a gradu...
