A Case of Abdominal Apoplexy / 日本心臓血管外科学会雑誌

This is a rare case of abdominal apoplexy encountered in a 50-year-old man who had aortic and mitral valve replacement due to dominant regurgitation resulting from infective eneocarditis. On the 4th day after the operation, retroperitoneal bleeding, probably due to rupture of the splenic artery aneurysm, occurred and he developed shock. On the 28th day, there was bleeding in the digestive tract and blood pressure was low, probably due to rupture of the microaneurysm of the small artery distributing to the ileum. Rupture of an abdominal vessel without a recognizable external cause is called abdominal apoplexy, and our case was caused by mycotic aneurysm caused by infective endocarditis. Angiography facilitated the accurate diagnosis.

Results of the Extra-anatomic Bypass Operation on Arterio Sclerosis Obliterans in Aorta and Iliac Artery / 日本心臓血管外科学会雑誌

Fifty-one cases which underwent surgery for arteriosclerosis obliterans in the aorta and iliac artery at the First Department of Surgery, Hiroshima University School of Medicine were divided into two groups. The EAB group (18 cases) underwent extra-anatomic bypass operation, and the AB group (33 cases) underwent anatomic bypass operation. A comparative study showed the mean age of the EAB group to be 10 years higher than that of the AB group, and the former group exhibited severer symptoms. Renal and pulmonary function declined in the EAB group, and the occurrence rate of complications such as cerebral infarction was also higher At operation, the following approaches were employed; long-term administration of PGE-1 before and after operation, operation with a better visual field under light general anesthesia, simultaneous reconstructive operation in peripheral lesions, artificial vessels of externally supported velour knitted Dacron. There was no case of obstruction in the past 5 years. Extra-anatomic bypass operation therefore provides as good postoperative patency as anatomic operation.

Result of Bypass Surgery for Arteriosclerosis Obliterans of Lower Extremities. Comparative Study on the Aorto-Iliac and Femoro-Popliteal Occlusion / 日本心臓血管外科学会雑誌

Patients who underwent the bypass operation during 5 years from 1987 to 1992 in the 1st Department of Surgery, Hiroshima University School of Medicine, were divided into 2 groups; AIOD group (51 cases) had lesions in the aorta and iliac artery, and FPOD group (46 cases) had lesions in the femoral artery and popliteal artery. A comparative study of these two groups was made. There was no significant difference in age, sex, symptom severity, smoking history, serum cholesterol level, serum triglyceride level. The complication rate of peripheral lesions of the AIOD group was 24% and of the FPOD group was 57%. The cumulative patency rate for 5 years of the AIDO group was 100% and of the FPOD group was 61%. The AIOD group exhibited better patency. In addition to the lower complication rate of peripheral lesions, all the AIOD group had underwent reconstruction operation for peripheral lesions simultaneously. The run-off state of the peripheral region may thus possibly be related to patency.
