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 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)
Nitrous oxide (N2O) production and expression of genes capable of its reduction were investigated in two full-scale parallel plug-flow activated sludge systems. These two systems continuously received wastewater with the same constituents, but operated under distinct nitrification efficiencies due to mixed liquor suspended solid (MLSS) concentration and the(More)
OBJECTIVE The present study was designed to assess whether pretreatment with nicorandil enhanced myocardial protection provided by cold (15 degrees C) high-potassium (25 mmol/l) blood cardioplegia during open heart surgery. METHODS Subjects were 40 patients with a variety of acquired heart diseases undergoing cardiac surgery involved cardiopulmonary(More)
OBJECTIVE This paper describes the long-term results of endoluminal grafting (EG) for the treatment of descending thoracic aortic aneurysms (dTAA). METHODS Until July 2004, EG for dTAA has been applied in 45 cases (male/female, 29/16, 49-86 years old, mean age 67 years old). Locations included the proximal dTAA in 24 cases, and middle or distal dTAA in 21(More)
The purpose of this study was to evaluate the effect of inflow phenomenon on TrueFISP. We created a phantom using a vinyl tube and distilled water, and applied a pump-oxygenator to the phantom to obtain stationary flow. First, to evaluate the effect of inflow and the dephase phenomenon on signal intensity, the phantom was measured for the signal intensity(More)
Emergency conventional surgical repair of the descending thoracic aorta remains a therapeutic challenge and is associated with a high risk of mortality. We describe a case of ruptured descending thoracic aortic aneurysm in an 87-year-old man who presented with chest and back pain. The patient underwent successful endovascular repair of the lesion with the(More)
Since the year 2000, our hospital has been equipped with an intensity modulated radiation therapy (IMRT) facility. Before IMRT is administered, the absorbed dose is measured by the ionization chamber to provide verification for the IMRT procedure. In utilizing the current point dose evaluation, large discrepancies have been experienced when the measured(More)
MR imaging (MRI) has been reported to be a useful modality to characterize breast tumors and to evaluate disease extent. Contrast-enhanced dynamic MRI, in particular, allows breast lesions to be characterized with high sensitivity and specificity. Our study was designed to develop three-dimensional volumetric interpolated breath-hold examination (3D-VIBE)(More)
