[Operative strategy for thoracoabdominal aortic aneurysm with concomitant reconstruction of four main abdominal branches].
A thoracoabdominal aortic aneurysm (TAAA) involving major abdominal branches remains still difficult to be managed. From 1983 to 1990, we successfully operated five such cases. Our operative strategy for TAAA which necessitates concomitant reconstruction of four major abdominal branches is i) to utilize temporary bypass to maintain distal perfusion during aortic cross-clamping, ii) to reconstruct bilateral renal arteries prior to aortic clamping in order to shorten renal ischemic time as much as possible, iii) to reconstruct celiac and superior mesenteric arteries by Crawford's method, iv) to reconstruct two pairs of intercostal arteries by using diagonal anastomosis in the proximal site, and v) to divide the left renal vein temporarily for easy manipulation of renal arteries. All five cases were recovered uneventfully. This procedure, in which the renal ischemic time is saved as short as possible, is considered a safe and reasonable one for thoracoabdominal aortic aneurysms.
