OBJECTIVE The purpose of this study was to define the pattern, rate, and interval during which stenosis develops in transjugular intrahepatic portosystemic shunts (TIPS) and to assess the effect of revision in prolonging shunt patency. MATERIALS AND METHODS TIPS were created in 100 patients during a 34-month period. Sixty-one shunt venograms were obtained(More)

Budd-Chiari syndrome is a heterogeneous group of disorders characterized by hepatic venous outflow obstruction that involves one or more draining hepatic veins. Its occurrence in populations in the western hemisphere is commonly associated with hypercoagulative states. Clinical manifestations in many cases are nonspecific, and imaging may be critical for(More)
PURPOSE To determine whether polytetrafluoroethylene (PTFE) stent-grafts yield longer patency for creation or revision of transjugular intrahepatic portosystemic shunts (TIPS). MATERIALS AND METHODS Fourteen PTFE-covered Wallstents were placed in 13 patients with TIPS: seven at shunt creation and seven during revision of TIPS with one to five prior(More)
The feasibility and efficacy of transjugular intrahepatic portosystemic shunts (TIPS) were evaluated in 10 patients with preexisting portal vein occlusions. A standard transjugular approach was used in six of the 10 patients for both portal vein recanalization and TIPS placement. The protal veins were successfully recanalized and TIPS were established in(More)
PURPOSE To report estimated radiation doses to the eye lens of the interventionalist from procedures performed with and without use of radiation protection measures. MATERIALS AND METHODS Scattered radiation doses for seven interventional radiology fluoroscopic systems were measured by using phantoms simulating patients 16-28 cm in thickness undergoing(More)
