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)
This study was designed to assess the safety of transcatheter arterial embolization (TAE) with n-butyl cyanoacrylate-lipiodol (NBCA-Lp) for the large bowel and to investigate the vital response to NBCA-Lp in a swine model. In nine swine, nine arteries nourishing the colon were embolized with NBCA-Lp (1 ml of NBCA mixed with 4 ml of lipiodol): sigmoid-rectal(More)
Pancreatic arteriovenous malformation (PAVM) is rare and is mainly reported from Asian countries. We incidentally encountered an asymptomatic, early-stage PAVM in a patient who presented with portal venous distention, Child B liver cirrhosis, and hepatoma. The PAVM had multiple feeding arteries and drainage into the portal vein and varices. Because surgery(More)
To compare the efficacy of transcatheter arterial chemoembolization (TACE) using multiple anticancer drugs (epirubicin, cisplatin, mitomycin C, and 5-furuorouracil: Multi group) with TACE using epirubicin (EP group) for hepatocellular carcinoma (HCC). The study design was a single-center, prospective, randomized controlled trial. Patients with unrespectable(More)
The aim of this study was to compare the safety and short-term efficacy of transcatheter arterial chemoembolization (TACE) using cisplatin-Lipiodol suspension (CP/Lp) with that using epirubicin-Lipiodol emulsion (EP/Lp) in patients with recurrent hepatocellular carcinoma (HCC). A total of 28 HCC patients were enrolled prospectively and assigned to the CP/Lp(More)
The purpose of this study was to evaluate change in the portal systemic pressure gradient (PSPG) following balloon-occluded retrograde transvenous obliteration (BRTO) and the aggravation of esophageal varices. The PSPG was monitored before and after BRTO in 19 patients. PSPG changes were obtained by subtracting the PSPG before BRTO from that after BRTO. The(More)
Large cell neuroendocrine carcinoma of the gall-bladder is a rare disease in which the prognosis worsens with size. We report a case of large cell neuroendocrine carcinoma of the gallbladder in a 64-year-old woman who presented with a right upper quadrant mass whose longest diameter was 11.5 cm; the mass was initially considered to be unresectable because(More)
Paraaortic lymph nodal (PALN) recurrence is not a rare scenario of abdominal malignancies including pancreas cancer, even after radiotherapy. The role and indication of reirradiation is limited because it is often associated with significant late toxicity in the surrounding normal organs. We developed a new approach and technique of brachytherapy to(More)
PURPOSE To assess the feasibility and efficacy of single photon emission computed tomography-based three-dimensional conformal radiotherapy (SPECT-B 3D-CRT) for large hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT). METHODS AND MATERIALS HCC patients with PVTT in the first branch or main trunk, 8 cm or greater in size, were admitted(More)
