In traumatic dislocation of the hip with or without a fracture of the acetabular rim, complete anatomical reduction might be prevented by a bone fragment or infrequently by a soft tissue block, such as a torn acetabular labrum, ruptured capsule, or round ligament. We report a rare case of a tear in the acetabular labrum that prevented complete reduction of(More)
Abdominal aortic aneurysm (AAA) is histologically characterized by medial degeneration and various degrees of chronic adventitial inflammation, although the mechanisms for progression of aneurysm are poorly understood. In the present study, we carried out histological study of AAA tissues of patients, and interventional animal and cell culture experiments(More)
The aim of this study was to investigate the change of hepatic metabolic activity presented by the ketone body ratio (AKBR) during and after cardiopulmonary bypass (CPB) and to evaluate the prognostic value. AKBR were measured in 20 cases of coronary aortic bypass grafting using moderate hypothermic CPB (group M), ten cases of aortic arch surgery using deep(More)
The research focuses on approach for robot' s vision system. We propose the selective visual attention system which realiz es high-speed processing flexible to environmental change. In order to obtain visual attention point, proposed system extracts three kinds of visual features: still image feature, blinking feature and motion feature. Proposed system(More)
BACKGROUND Type A intramural hematoma (IMH) has two different etiologies, which are rupture of vasa vasorum and penetrating atherosclerotic ulcer (PAU); however, it is difficult to know which is the initiating event. METHODS Between January 1993 and August 2004, 28 patients of acute type A IMH were treated in our department and were divided into two(More)
OBJECTIVES Less invasive stent graft (SG) repair was compared with open surgery for patients with descending thoracic aortic diseases. DESIGN Thirty six patients undergoing SG repair (SG group) were matched for age, sex, location and pathology of aortic disease with a 36-patient surgical cohort (OS group), and retrospective matched case-control study was(More)
An asymptomatic cardiac neurilemoma was found in a 33-year-old woman. The tumor was on the anterior surface of the right atrium extending to the right upper pulmonary vein across the interatrial groove. The tumor was resected completely and right atrium, interatrial septum, left atrium and right superior pulmonary vein were reconstructed with(More)
