    Abstract:
    AIM OF THE STUDY: About 30% of the patients with acute aortic dissection suffer from organ or limb ischemia. We analyzed the influence of ischemic localization and method of operative treatment (aortic fenestration or extraanatomic bypass revascularization) on morbidity and mortality. PATIENTS AND METHODS: From 1 May 1987 to 31 December 1998 21 patients with 24 vascular complications such as renal or intestinal ischemia, lower extremity ischemia and paraplegia following acute aortic dissection were treated at our institution. Recruitment was retrospective in 16 and prospective in 5 patients. In 5 patients (24%) the complication was associated with Stanford A, in 16 (76%) with Stanford B dissection. Ten patients (48%) complained of malperfusion of only one region, whereas 11 patients (52%) suffered from ischemia of two or three different regions. Aortic fenestration and resection of the dissected membrane was performed in nine cases (37%). Fifteen patients (63%) were treated with extraanatomic bypass techniques. RESULTS: One third of the patients died, four of them due to aortic penetration or perforation and two due to visceral ischemia. During follow-up of 32 (1-110) months two patients developed aortic complications. One died of aortic perforation, while the other developed a thoracoabdominal aneurysm and had to be treated by a tube graft replacement. CONCLUSIONS: Outcome depended more on the spontaneous course of aortic dissection and on prompt diagnosis and therapy of the complications than on the different operative techniques.
