Real-time virtual sonography (RVS) is a diagnostic imaging support system, which provides the same cross-sectional multiplanar reconstruction images as ultrasound images on the same monitor screen in real time. The purpose of this study was to evaluate radiofrequency ablation (RFA) assisted by RVS and CT for hepatocellular carcinoma (HCC) undetectable with(More)
AIM To evaluate safety and feasibility of microcoil embolization of the common hepatic artery under proper or distal balloon inflation in preoperative preparation for en bloc celiac axis resection for pancreatic body cancer. METHODS Fifteen patients (11 males, 4 females; median age, 67 years) with pancreatic body cancer involving the nerve plexus(More)
Gelatin sponge (GS) is one of the most widely used embolic agents in interventional procedures. There are four commercially available GS products in Japan; however, the endovascular use of Gelfoam and Spongel is off-label, and Gelpart can only be used for hepatic artery embolization and Serescue can only be used for hemostasis of arterial bleeding. GS has(More)
It has been confirmed gradually that transcatheter arterial embolization is the most effective, conservative therapy for the treatment of unresectable hepatic cell carcinoma (hepatoma). Embolization or one shot therapy was carried out in a clinical trial involving 41 patients with unresectable hepatoma visiting our department. Embolization group (emboli G):(More)
To assess the efficacy of Doppler ultrasonography (US) as a noninvasive method for monitoring patency of the transjugular intrahepatic portosystemic shunt (TIPS). Twenty-nine patients who had received TIPS for bleeding esophagogastric varices and/or refractory ascites with portal hypertension underwent Doppler US studies within 2 weeks after TIPS.

Percutaneous osteoplasty has been used for pathologic fractures of long bones as an adjunct to orthopedic surgery. The present report describes a case of percutaneous osteoplasty with a cement-filled catheter and cement augmentation as the principal therapy to unite a painful pathologic fracture of the humerus. After the procedure, the patient experienced(More)
In order to evaluate the effects of hepatic artery embolization (HAE) with Lipiodol (Lp) and gelatin sponge particles (GSP) on swine liver tissue, we embolized the hepatic arteries of 3 pigs with GSP, 9 with Lp, and 9 with Lp+GSP. None of the pigs embolized with GSP died spontaneously during the 4-week experimental period. One pig embolized with 1 ml/kg Lp(More)
PURPOSE To evaluate the effectiveness of transcatheter arterial embolization (TAE) on radiofrequency (RF) ablation volume and compare portal vein (PV) flow and liver parenchymal pressure before and after treatment. MATERIALS AND METHODS Eight healthy female swine were divided into four groups to be treated with RF ablation alone (RF-only group), RF(More)
