[Surgical treatment thoracoabdominal aortic aneurysms with blocking of aorta at short intervals].
Visceral ischemia and deterioration in renal function is common cause of morbidity in patients with thoracoabdominal aortic aneurysm surgically treated. Two patients with huge thoracoabdominal aortic aneurysm were surgically treated by a new technique of shunting. The operation was performed by using a synthetic artificial graft, which was sutured to the iliac artery by end to side anastomosis, and the upper end of the graft was anastomosed to the cut end of the thoracic aorta by end-to-end method. Compared with the traditional temporary shunting, there are several advantages in using the improved shunting technique. First, by so doing the ischemic time of various viscera could be fractionated and shortened, just about 17 minutes. visceral ischemic complication can be avoided. Second the pseudoaneurysm produced by the traditional method of temporal shunting could be prevented by the improved method. Third, on account of the ischemic time of the viscera is decreased, operation could be done under normal temperature without need for hypothermia. In treating a case of huge thoracoabdominal aortic aneurysm, successful result could hardly be obtained without good prepostopoerative care. We should also emphasize that the improvement of some surgical technique is also important.
