Surgical Treatment of Multiple Aortic Aneurysm / 日本心臓血管外科学会雑誌

ABSTRACT

Eight patients with multiple aortic aneurysms of both the thoracic and abdominal aortae treated surgically from 1991 to 1995 were evaluated clinically. The patients consisted of six men and two women, with an average age of 65.6 years ranging from 50 to 73. The incidence of multiple aortic aneurysms was about 10% of all cases of aortic aneurysms. The entire aorta should be examined in all patients with aortic aneurysms. Among the five patients who underwent a two-staged operation, the thoracic operation preceded the abdominal one in one case, and the abdominal operation preceded the other in four cases. No aneurysm rupture occurred in the two-staged cases. In conclusion we should first replace the aneurysm with the higher risk of rupture. However, when such a judgement is difficult, it is improtant to consider the possibility of a rupture of the second aneurysm or a brain infarction caused by a thrombosis moving from the abdominal aneurysm. The order of operation should be decided according to the location and the size of the thoracic aneurysm.
