UNLABELLED Portal vein thrombosis is a poor prognostic factor in patients with hepatocellular carcinoma (HCC) and a contraindication for chemoembolization. Intra-arterial injection of 131I-iodized oil which does not modify arterial flow, is feasible in this condition. The aim of this prospective randomized controlled trial was to compare the efficacy of treatment with radiolabeled oil (treated ...

BACKGROUND AND PURPOSE The purpose of this study was to evaluate the correlation between appearance of angiographic early venous filling during intra-arterial reperfusion therapy and posttherapeutic hemorrhagic complications. METHODS For the past 7 years, 104 patients prospectively underwent superselective local angiography via a microcatheter before and during intra-arterial reperfusion ther...

PURPOSE To investigate the risk factors leading to blood transfusion among Chinese patients undergoing total knee replacement. METHODS From July 2001 to June 2002, a total of 128 primary total knee replacements were performed in 83 Chinese patients (38 unilateral and 45 one-stage sequential bilateral). No pharmaceutical prophylaxis against deep vein thrombosis was used. The risk factors leadi...

BACKGROUND Atrial fibrillation (AF) commonly associates with atrial dilatation by poorly understood mechanisms. We hypothesized that elevation of intra-atrial pressure elicits high-frequency and spatio-temporally organized left atrial (LA) sources emanating from the superior pulmonary veins. METHODS AND RESULTS We used a stretch-related AF model in the sheep heart to induce stable episodes of...

BACKGROUND AND PURPOSE Cerebral venous thrombosis is a rare entity that can be difficult to manage. Intrasinus thrombolysis is an increasingly applied intervention, but this modality carries an increased risk of hemorrhage. We describe for the first time an option with a potentially lower incidence of intracranial bleeding, the combination of the AngioJet rheolytic thrombectomy catheter with in...

AIM Left ventricular (LV) lead placement in the latest activated region is an important determinant of response to cardiac resynchronization therapy (CRT). We investigated the feasibility of coronary venous electroanatomic mapping (EAM) to guide LV lead placement to the latest activated region. METHODS AND RESULTS Twenty-five consecutive CRT candidates with left bundle-branch block underwent ...
