PURPOSE To compare multi-detector row spiral computed tomographic (CT) angiography with digital subtraction angiography (DSA) in evaluation of the infrarenal aorta and lower-extremity arterial system. MATERIALS AND METHODS Fifty patients with peripheral arterial occlusive disease were evaluated with multi-detector row CT angiography and DSA. Arteries(More)
PURPOSE In this retrospective multicenter study, the authors analyzed the clinical efficacy of different metallic stents in the palliative treatment of patients with neoplastic obstructive jaundice. PATIENTS AND METHODS Two hundred forty patients were treated in four European centers. Causes of obstruction were pancreatic carcinoma (n = 84), biliary(More)
Self-expanding metallic stents of a modified Gianturco design were used to treat benign strictures of the biliary tree in 17 patients. Thirteen patients had undergone several unsuccessful surgical repairs, and four had not undergone surgery because of their clinical status. All patients had already undergone multiple percutaneous balloon dilations without(More)
To compare clinical effectiveness of Viabil-covered stents versus uncovered metallic Wallstents, for palliation of malignant jaundice due to extrahepatic cholangiocarcinoma, 60 patients were enrolled in a prospective and randomized study. In half of the patients a bare Wallstent was used, and in the other half a Viabil biliary stent. Patients were followed(More)
Purpose: To evaluate the effectiveness of partially covered metallic Wallstents to prevent tumoral ingrowth in patients with neoplastic obstruction of the biliary tract. Methods: Twenty-one patients with malignant obstructive jaundice have been treated with Wallstents partially covered with a polyurethane polymer. In total, 36 covered stents (8 and 10 mm in(More)
Forty-seven consecutive patients were prospectively evaluated to study the incidence of hepatic encephalopathy as well as modifications in the PSE index after TIPS. Various clinical, laboratory, and angiographic parameters were also recorded to identify risk factors for the development of post-TIPS hepatic encephalopathy (HE). Mean follow-up was 17 +/- 7(More)
PURPOSE To determine the technical efficacy and safety of an expanded polytetrafluoroethylene and fluorinated ethylene propylene (ePTFE/FEP)-covered metallic stent in the management of malignant biliary obstruction and to evaluate its clinical efficacy by estimating stent patency and patient survival rates. MATERIALS AND METHODS Twenty-six patients with(More)
Despite the availability and wide use of modern imaging techniques, the diagnosis of Meckel's diverticulum is difficult. The signs and symptoms vary from none to those of an acute abdomen or gastrointestinal bleeding. Findings on physical examination may be inconsistent because of the variable location of the diverticulum, and bleeding may occur with no(More)
The sensitivity of preoperative imaging was evaluated for the localization of insulinomas in 2 series of 54 and 17 patients, respectively. In the first series, diagnosis was obtained with ultrasonography (US) in 14.8%, with computed tomographic (CT) scan in 60%, and with arteriography and/or angio CT scan in 75% of patients. In the second series, US, CT(More)
BACKGROUND/AIMS Hepatic encephalopathy is a frequent event after transjugular-intrahepatic-portosystemic-shunt (TIPS), especially during the first months. Aim of this study was to compare two different treatments (lactitol 60 g/day, rifaximin 1200 mg/day) with no-treatment in the prevention of post-TIPS hepatic encephalopathy. METHODS Seventy-five(More)
