[Surgery of aortic arch aneurysm combined with other cardiovascular lesion]

From 1995 to 1996, we performed aortic arch replacement using antegrade cerebral perfusion under deep hypothermia in 7 patients, in whom 4 cases accompanied with cardiac lesion which treated simultaneously and 3 cases had abdominal aortic aneurysm. We compared the surgical results between cases with (group II, n = 4) and without (group I, n = 3) combined cardiovascular lesion. There is no difference between two groups in the cerebral perfusion time and the amount of bleeding and blood transfusion. The cardiac ischemic time and bypass time were insignificantly longer in group II than in group I. We experienced no early death and no cardiac and brain complication in both groups. Three cases with abdominal aortic aneurysm had two-staged operation successfully after arch surgery within a half year. In conclusion, we successfully treated aortic arch aneurysm even in patients combined with other cardiovascular lesion as well as in patients without that.
