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)
PURPOSE To analyze in detail the location and types of stenosis and occlusion that occur after transjugular intrahepatic portosystemic shunt (TIPS) creation and to determine the relative contribution of these various types of TIPS malfunction to recurrent symptoms of variceal bleeding or ascites. MATERIALS AND METHODS In 116 of 217 patients who underwent(More)
PURPOSE To describe the use of intravascular ultrasound (US) guidance for creation of transjugular intrahepatic portosystemic shunts (TIPSs) in humans. MATERIALS AND METHODS The initial 25 cases of intravascular US-guided TIPS were retrospectively compared versus the last 75 conventional TIPS cases during the same time period at the same institution in(More)
BACKGROUND Intrahepatic abscess (IA) is an uncommon complication after liver transplantation (OLTx) usually found in the setting of hepatic arterial thrombosis (HAT) often with associated biliary tree necrosis and/or stricture. Conventional treatment of IA in this setting has required retransplantation. METHODS A retrospective review of 274 patients (287(More)
BACKGROUND Patients with hepatic metastases often develop obstruction of the intrahepatic inferior vena cava (IVC), known as IVC syndrome. This obstruction is debilitating due to the development of ascites and anasarca. OBJECTIVES To update our experience in the diagnosis and treatment of IVC syndrome and to evaluate the efficacy of expandable stents in(More)
We evaluated the clinical outcome of malignant inferior vena cava (IVC) syndrome after intrahepatic IVC stent placement by retrospective analysis of 50 consecutive patients (25 men, 25 women, age 32-83 years) with malignant IVC syndrome who were treated with intrahepatic stent placement. Gianturco-Rosch-Z (GRZ) stents (n = 45), and Wallstents (n = 5) were(More)
PURPOSE To prospectively evaluate the clinical efficacy of silicone-covered Gianturco-Rösch self-expandable Z (GRZ) stents in the treatment of malignant esophageal obstruction. PATIENTS AND METHODS GRZ stents were placed in 52 patients (39 men, 13 women) with severe dysphagia due to high-grade malignant esophageal obstruction. RESULTS Stent placement(More)
PURPOSE To evaluate a new 19-gauge blunt-tipped, side-cutting, single throw transjugular biopsy needle for transvenous kidney biopsies. MATERIALS AND METHODS Transjugular transvenous kidney biopsies were performed with a modified 70-cm biopsy needle utilizing fluoroscopic guidance in nine swine. Three tissue specimens were obtained with four biopsy device(More)
PURPOSE To prospectively evaluate the clinical efficacy of covered metallic Z stents in the treatment of esophagorespiratory fistulas (ERFs). PATIENTS AND METHODS Twelve patients with severe aspiration symptoms from malignant ERFs were treated with silicone-covered, metallic, self-expanding Gianturco-Rösch Z (GRZ) stents. RESULTS Fluoroscopically guided(More)
