PURPOSE To assess midterm results and examine factors associated with successful treatment of refractory ascites with creation of a transjugular intrahepatic portosystemic shunt (TIPS). MATERIALS AND METHODS In 50 patients with refractory ascites, TIPS creation was performed. Clinical and ultrasound follow-up were performed. Success was defined as(More)
PURPOSE To prospectively evaluate the angiographic and clinical results of using catheter-directed thrombolytic therapy for the treatment of acute iliofemoral deep venous thrombosis (IFDVT). MATERIALS AND METHODS All consecutive patients with acute IFDVT referred for thrombolytic treatment from July 1990 to December 1995 were included in this clinical(More)
PURPOSE To assess effectiveness of metallic endovascular stents in treatment of venous stenoses and occlusions. MATERIALS AND METHODS Stents were placed intravenously in 56 patients (59 stenoses or occlusions) over a 6-year period. Stent sites included the inferior vena cava (n = 10) and common iliac (n = 31), external iliac (n = 46), common femoral (n =(More)
PURPOSE To evaluate the frequency and significance of stenoses or occlusions developing within transjugular intrahepatic portosystemic shunts (TIPS) and identify predictive factors. MATERIALS AND METHODS Medical records of 52 patients who underwent TIPS placement between September 1991 and October 1993 were reviewed. Various shunt parameters were(More)
A study was conducted to investigate how operator exposure in interventional radiology is affected by various common fluoroscopic imaging conditions. Stray radiation levels surrounding the imaging chain of a C-arm angiographic system were measured with an anthropomorphic abdomen phantom under different imaging conditions, and isodose curves were(More)
OBJECTIVES This study sought to assess clinical and angiographic outcomes in a series of 29 patients who underwent transcatheter closure of coronary artery fistulae (CAF). BACKGROUND Transcatheter closure of CAF has become an alternative to surgical closure, but the reported experience is relatively limited. METHODS Medical records of all patients with(More)
The purpose of this study was to evaluate duplex and color Doppler findings in patients before and within 24 h after transjugular intrahepatic porto-systemic shunts (TIPS). Conventional duplex and color Doppler were used in the assessment of 19 patients who underwent TIPS as part of a prospective protocol. Patients were examined within 24 h before and after(More)
OBJECTIVE To identify the risk of venous thromboembolism recurrence, major bleeding, and mortality in patients with ovarian vein thrombosis so as to better define optimal treatment strategies. METHODS Patients with ovarian vein thrombosis (1990-2015) and age- and gender-matched patients with contemporary leg deep vein thrombosis (DVT) were assessed for(More)
BACKGROUND Endovascular repair (EVR) is emerging as first-line treatment for patients with superior vena cava (SVC) syndrome of benign etiology, but data on its durability remain scarce. The aims of this study were to assess the efficacy and durability of EVR and compare results of EVR with open surgical reconstruction (OSR). METHODS Data from 70(More)
