OBJECTIVE Stent grafts are increasingly recognized as useful devices for endovascular repair of aortic aneurysms and other vascular diseases. Stent graft-mediated gene delivery into the vascular wall is expected to improve their therapeutic effects. This study evaluated the efficacy of genetically engineered cationized gelatin (CG) hydrogel-coated(More)
PURPOSE To present a new endovascular technique for placing handmade partially covered stent-grafts in rabbit aortas that is promising for experimental study of direct gene delivery to the aortic wall. METHODS A 7-mm-diameter Z-stent made from the inner core of a guidewire was covered with a 7-mm-diameter, 10-mm-long polyester fabric tube (2268 mL(More)
A rare case of severe intestinal bleeding caused by sinistral portal hypertension after pylorus-preserving pancreatoduodenectomy is reported. Examinations revealed that the developed collateral vessels adjacent to the pancreas and elevated jejunum in the right upper abdomen were the source of the intestinal bleeding, and typical gastric varices were not(More)
Three middle-aged male patients were admitted to our hospital complaining of dry cough, dyspnoea, and fever. All three of them had cleaned a refrigerator at a Chinese noodle mill using paint remover containing dichloromethane (90%) the previous day. Chest X-rays revealed bilateral diffuse infiltrative shadows on the lungs. We performed transbronchial lung(More)
The mortality rate of patients with ruptured pancreaticoduodenal artery aneurysms is high; therefore, it is recommended to treat pancreaticoduodenal artery aneurysms regardless of their size. In small pancreaticoduodenal artery aneurysms, however, identification of the access route on two-dimensional arteriography is sometimes difficult because of the(More)
PURPOSE To evaluate the feasibility and effectiveness of transcatheter embolization by forcible intraarterial injection of a mixture of ethylene vinyl alcohol copolymer (EVAL) and ethanol under microballoon occlusion compared with conventional transcatheter arterial embolization methods in nontumoral swine liver. MATERIALS AND METHODS Nine swine were(More)
PURPOSE To evaluate the local reaction of the aortic wall induced by basic fibroblast growth factor (bFGF) released from a gelatin hydrogel coated on the outer surface of a stent-graft for the purpose of biological fixation. METHODS A total of 18 nitinol-based, polyester-covered stent-grafts were implanted in 6 porcine aortas for 1 month. The implanted(More)
