The purpose of this study is to clarify the appropriateness of axillofemoral bypass for high-risk patients with aortoiliac occlusive disease. From February 1986 through November 1997, 50 axillofemoral bypasses were performed at our institution. The mean age of patients was 70.3± 9.6 years (range 28 to 86 years) and 90% of them had severe associated disease. Twenty-nine grafts had axillounifemoral configuration and 21 grafts had axillobifemoral configuration. The primary and secondary patency rate, during this 11-year period (mean follow-up 47.0±30.1months), were 66.4 % and 78.3% at 5 years, with no change thereafter. The mortality rate within 30days was 2%. During the follow-up period 22 died mainly due to heart disease, cerebrovascular disease or malignant tumor, and the survival rate at 5 years was 56.3%. Fontaine classification evaluation revealed that ischemic symptoms improved in 78% of 28 survivors. According to QOL study 75% of survivors were satisfied with daily life, and their performance status improved after operation. These findings indicate that axillofemoral bypass may be an appropriate procedure for high risk patients with aortoiliac occlusive disease.

Ninety patients with abdominal aortic aneurysm underwent endovascular stent grafting in our hospital between 2001 and 2006 and two patients required graft replacement of abdominal aortic aneurysms during the late postoperative phase. Case 1 was a 77-year-old man for whom endovascular stent grafting for an abdominal aortic aneurysm and thoracic aortic aneurysm had been performed concomitantly. Six months later, because the abdominal aortic aneurysm had expanded from 68mm to 75mm in diameter, due to a type I endoleak which was detected postoperatively, he underwent open surgery. An occlusion balloon was inflated at the proximal site of the celiac artery until the stent graft was extracted. After positioning the aortic clamp below the origin of the renal arteries, a bifurcated graft was implanted. The postoperative course was uneventful. Case 2 was an 86-year-old woman who had undergone endovascular stent grafting for an abdominal aortic aneurysm. The endovascular procedure was successful and no endoleak was detected postoperatively. However, 13 months later, a community hospital admitted her in a state of shock due to ruptured abdominal aortic aneurysm. She was transferred to our hospital and underwent an emergency operation. Because insertion of an occlusion balloon into the brachial artery failed, we primarily performed supravisceral aortic cross clamping. After opening the aneurysm sac, the stent graft was removed and a bifurcated graft was implanted. After declamping, we found that the right common iliac artery was occluded, and therefore aorto-right external iliac bypass grafting was then also performed. The postoperative course was uneventful.

A 76-year-old man with a history of total esophagectomy and retrosternal gastric tube reconstruction for esophageal cancer was transferred to our hospital because of consciousness disorder. It became an emergency operation on diagnosis of Stanford type A acute aortic dissection on enhanced CT. Because CT showed the retrosternal gastric tube ran along the right side of the body of the sternum through the back side of the manubrium, we opted for skin and the suprasternal incision on the left side from center. We could perform total aortic arch replacement without the damage of the gastric tube except that the right side of the operative view was slightly poor. We did not recognize digestive organ symptoms such as postoperative passage disorders nor mediastinitis. The patient was discharged from our hospital on postoperative day 24.
