During the period from January 1972 to September 1984, 285 patients were admitted and treated operatively for abdominal aortic aneurysm (AAA). At operation a non-ruptured AAA was found in 177 patients and a ruptured AAA in 108 patients. Advanced age and reduced renal function were found by employment of Cox's regression analysis to influence the peroperative and postoperative mortalities. The commonest cause of postoperative death was renal failure both in cases of non-ruptured and ruptured AAA. The commonest causes of late deaths were coronary occlusion, malignant disease, cerebral haemorrhage and haemorrhage from the anastomosis.

Between January 1991 and June 1993, coronary artery bypass grafting was performed without either cardiopulmonary bypass or cardiac arrest in 23 patients. Most patients had several surgical risk factors, including age > or = 70 years, poor left ventricular function, left main coronary artery stenosis, chronic renal failure, and aortic aneurysm. Distal anastomoses were made under temporary interruption of coronary flow. A total of 37 distal anastomoses to the left anterior descending coronary artery and/or right coronary artery (mean 1.6 per patient) were made, 24 of which were internal thoracic arteries. The coronary occlusion time ranged from 7-14 min (mean 9.8 min). Combined cardiac or vascular operations were carried out in six patients (abdominal aortic aneurysm repair, thoracic aortic aneurysm repair, carotid endarterectomy, and coronary endarterectomy). There was one hospital death. Postoperative angiography was performed in 22 patients and showed a patency rate of 89%. In summary, coronary artery bypass grafting without cardiopulmonary bypass may improve the postoperative outcome of high-risk patients.

We present a patient with a descending aortic dissection and contained rupture of a large abdominal aortic aneurysm with a history of inferior myocardial infarction and right coronary occlusion. The technique of combined repair of the descending thoracic aortic dissection with replacement of the ruptured infrarenal abdominal aorta and coronary artery bypass grafting is described.

The clinical experiences of 29 consecutive MIDCAB procedures performed at our institution between October, 1996, and October, 1997, were analyzed. Preoperative patient's characteristics were as follows; LAD single vessel disease: 25, double vessel disease: 1, triple vessel disease: 1, RC single vessel disease: 1, LMT lesion: 1, concomitant procedures: 2 (ASO: 1, AAA: 1). LITA harvesting was performed using the video-assisted thoracoscopy in initial 4 patients, and in last 10 patients we used the specially designed retractor THORALIFT (Autosuture Co., Ltd.) for harvesting LITA by direct vision. LAD was stabilized mechanically using the stabilizer when we performed the anastomosis in last 10 patients to enhance the quality of the anastomosis. The patency rate was 96%, but there were two patients (6%) who had the stenosis of the anastomosis site. Coronary artery occlusion time was 13.2 minutes in the mean. We also studied the hemodynamics of blood flow in LITA grafts with the aid of 7.5 MHz transthoracic duplex imaging in these MIDCAB patients and compared with the LITA grafts in conventional CABG performed in same periods. There were no statistical differences between the two groups about the graft flow and velocity. We conclude that MIDCAB would be an alternative procedure that can be performed with low risk and acceptable early results in selected patients.
