BACKGROUND Sustained benefits of drug-eluting stents in femoropopliteal arteries have not been demonstrated. This prospective, multinational, randomized study was designed to compare the 12-month safety and effectiveness of a polymer-free, paclitaxel-coated nitinol drug-eluting stent (DES) with percutaneous transluminal angioplasty (PTA) and provisional(More)
Esophagogastric malignancies often are manifested with progressive dysphagia or esophagorespiratory fistulas. Palliative modalities currently available have significant limitations. A modified Gianturco-Rösch silicone-covered self-expanding metallic Z stent was used in 32 consecutive patients with malignant esophageal obstruction (n = 24) or(More)
PURPOSE To evaluate the ability of stent-grafts made with polytetrafluoroethylene (PTFE) graft material to improve transjugular intrahepatic portosystemic shunt (TIPS) patency. MATERIALS AND METHODS TIPS were created in 13 swine by using PTFE-covered stent-grafts. Uncovered TIPS were placed in 13 other swine. Twenty-one of 26 animals were followed up with(More)
PURPOSE To assess the clinical and technical results of stent-graft placement for revision of transjugular intrahepatic portosystemic shunt (TIPS) stenoses and occlusions. MATERIALS AND METHODS Six patients who developed recurrent TIPS stenosis or occlusion of the parenchymal tract underwent shunt revision with use of polytetrafluoroethylene (PTFE)(More)
PURPOSE To prospectively evaluate the clinical efficacy of polyethylene-covered metallic Z-stents in treatment of dysphagia secondary to malignant esophageal obstruction and esophagorespiratory fistula. MATERIALS AND METHODS Thirty-five patients with dysphagia due to malignant esophageal obstruction (n = 32) and esophagorespiratory fistula (n = 3) were(More)
OBJECTIVES A prospective, multinational randomized controlled trial (RCT) and a complementary single-arm study evaluated the 2-year safety and effectiveness of a paclitaxel-coated drug-eluting stent (DES) in patients with superficial femoral artery lesions. The RCT compared the DES with percutaneous transluminal angioplasty (PTA) and provisional bare-metal(More)
IN the last 5 years, the transjugular intrahepatic portosystemic shunt (TIPS) procedure has become widely disseminated. The number of interventional radiologists who are creating shunts has steadily increased as the procedure has become an accepted method of reducing portal vein pressure (1–28). Although the optimal technique for shunt creation continues to(More)
PURPOSE To evaluate the performance of a heparin-bonded, expanded polytetrafluoroethylene (ePTFE)-lined nitinol endoprosthesis in the treatment of long-segment occlusive disease of the femoropopliteal artery (FPA) and to identify factors associated with loss of patency. MATERIALS AND METHODS In a single-arm, prospective, 11-center study (VIPER [Gore(More)
BACKGROUND Self-expanding metallic stents (SEMS) are effective in relieving the symptoms of obstructing esophagogastric malignancy. While complications with SEMS have been described, factors influencing such occurrence have not been defined. METHODS Self-expanding Gianturco-Rosch Z-stents were placed successfully in 59 patients with obstructing(More)
PURPOSE A comparative histologic analysis of human and swine transjugular intrahepatic portosystemic shunts (TIPS) was performed to investigate factors limiting TIPS patency and to further develop an animal model for TIPS. MATERIALS AND METHODS Twenty-one human and 13 porcine shunts were evaluated by means of gross inspection, histologic evaluation, and(More)
