PURPOSE To retrospectively and prospectively determine the rate and type of complications and their association with clinical or technical factors after percutaneous laser ablation (LA) for hepatocellular carcinoma (HCC). MATERIALS AND METHODS The institutional research board of each center approved the study and all patients provided informed consent. By(More)
When Budd-Chiari syndrome (BCS) is due to occlusion of all three hepatic veins, the standard transjugular intrahepatic portosystemic shunt (TIPS) technique can be extremely laborious. A feasible alternative is to use the direct transcaval approach, by which a shunt can be created directly between the intrahepatic inferior vena cava and the portal vein. We(More)
PURPOSE The aim of this study was to assess the effectiveness of a combination of percutaneous radiofrequency thermal ablation (RF), stop-flow and transcatheter arterial chemo-embolisation (TACE) in the treatment of hepatic neoplasms. MATERIALS AND METHODS From December 1997 to September 2000, 34 patients with hepatocellular carcinoma (HCC) underwent(More)
AIM To evaluate the efficacy of a new sclerotization technique with pure ethanol in the treatment of symptomatic renal cysts. PATIENTS AND METHODS Fourteen patients having renal cysts with a meant diameter of 10 (range 5-15) cm were treated. Our technique includes: ultrasound-guided percutaneous puncture with an 18-gauge needle, positioning of a 5-Fr(More)
We treated three cases of early portal vein thrombosis (PVT) by minimally invasive percutaneous transhepatic portography. All patients developed PVT within 30 days of major hepatic surgery (one case each of orthotopic liver transplantation, splenectomy in a previous liver transplant recipient, and right extended hepatectomy with resection and reconstruction(More)
BACKGROUND/AIMS Though hepatocellular carcinoma (HCC) is one of the most frequent malignant tumors in the world, the optimal therapeutic strategy is still poorly defined. This is mainly due to geographic differences in HCC which may affect the validity of treatment regimens in differents areas of the world. The aim of the present study was to analyze the(More)

AIMS The aim of the present study was to evaluate peri-procedural and 30-day outcomes in a prospective series of patients treated with the CGuard embolic prevention stent system (EPS). METHODS AND RESULTS From April 2015 to June 2016 a physician-initiated prospective multicenter study was performed in 200 consecutive patients admitted to protected carotid(More)
A hundred patients with different conditions underwent CT and the results were retrospectively reviewed to evaluate the visibility of the celiac trunk, of its branches and of the superior mesenteric artery. Thirty-six patients underwent angiography too, which allowed the anatomical variants suspected on CT to be demonstrated, according to Kuhns' criteria.(More)
PURPOSE Peripheral aneurysms are usually located in the femoro-popliteal district; these lesions may present some complications such as distal embolisation and thrombosis; rupture is quite rare, but may be life-threatening. The aim of this study is to test the accuracy of CT multislice angiography in the assessment of this pathology and to compare it with(More)
