PURPOSE We report on the optimal stent-graft (SG) size for Japanese patients with abdominal aortic aneurysm (AAA). MATERIALS AND METHODS Ninety three Japanese patients undergoing elective AAA repair were selected for this study. The parameters measured were the proximal neck (PN) diameter (D1), the diameter of the right and left common iliac arteries (D2(More)
OBJECTIVE Our purpose was to examine the use of fully supported open stent grafting (OSG) with a Matsui-Kitamura (MK) stent for treatment of distal arch aneurysm (DAA). METHODS Surgery was performed using a newly developed device in seven DAA patients (six men and one woman) from 58 to 86 years of age (mean, 73 years old) from August 2005 to June 2007.(More)
OBJECTIVES Functional tricuspid regurgitation (FTR) is generally caused by the dilation of the tricuspid annulus (TA) and the tethering of tricuspid leaflets; however, it also occurs in patients without dilatation of the TA. The aim of this study was to develop and to use a four-dimensional tracking system, utilizing cardiac magnetic resonance imaging(More)
Percutaneous transluminal laser-assisted angioplasty of a renal artery stenosis was performed in a 16-year-old woman with renovascular hypertension. The stenotic portion of the renal artery was predilated by delivering Nd-YAG laser energy to the terminal tip of a laser catheter. Although the luminal diameter did not increase sufficiently with laser(More)
OBJECTIVE To evaluate the efficacy of a temporary balloon occlusion test for the prevention of paraplegia following transluminally placed endoluminal prosthetic grafts for descending thoracic aortic aneurysms. SUBJECTS AND METHODS Two occlusion balloons were inserted via the brachial and femoral arteries and positioned in the proximal and distal neck of(More)
Fifteen patients with advanced hepatocellular carcinoma were treated by hepatic arterial infusion (HAI). Treatment consisted of a 24-hour continuous HAI of etoposide (60 mg/day, day 1-5), CDDP (30 mg/day, day 1-5) and 5-fluorouracil (250 mg/day, day 1-26). Three patients had two series of infusions. Five patients were treated by transcatheter arterial(More)
OBJECTIVE Catheter-directed thrombolysis (CDT) is a promising treatment of acute proximal deep vein thrombosis (DVT) to prevent the postthrombotic syndrome by early removal of thrombus. During CDT for DVT patients, the calf muscle pump is compromised because of immobility. Intermittent pneumatic compression (IPC) can be used to increase venous flow during(More)
BACKGROUND The purpose of the present study is to clarify the influence of acute and chronic interruption of blood flow from lumbar arteries as well as the influence of vascular reconstruction on low back pain, back muscles, and lumbar discs. METHODS Subjects were 34 patients with AAA in whom vascular reconstruction was performed. A second group was(More)
PURPOSE To describe a case of graft-wall endoleak 18 months after successful endoluminal repair of an abdominal aortic aneurysm (AAA). METHODS AND RESULTS A 71-year-old man with infrarenal AAA was successfully treated with an endoluminal aortomonoiliac graft and femorofemoral crossover bypass with surgical ligation of the right external iliac artery. The(More)
