title: [Vascular complications associated with aortic dissection].
abstract: Aortic branch occlusion may constitute the mode of presentation or become an important focus of treatment in patients sustaining acute aortic dissection. The optimal therapeutic approach in patients with acute aortic dissection complicated by cerebral, visceral and peripheral vascular problems, and the implications of such complications, are not well established. We review the outcome in 187 consecutive patients (149 males and 38 females, mean age 58 years) with acute dissection of the thoracic aorta who were admitted and operated on in our department over a 13-year period. We assess the incidence, consequences and specific management of significant stenotic and obstructive lesions of the aorta and its branches. Noncardiac vascular complications occurred in 59 patients (32%); of these complications, 38 were associated with type A dissection (incidence 28%) and 21 with type B dissection (incidence 48%). A trend towards decreasing overall surgical mortality was observed in the second part of the study (1983-1989) compared with the first part (1977-1982) i.e. 28% versus 12%. Although aortic rupture and cardiac tamponade were the strongest correlate of morbidity and mortality, death specifically related to vascular complication was more common when such malperfusion occurred in the carotid, celio-mesenteric and renal circulation. Proximal aortic repair at the site of the intimal tear with obliteration of the false lumen may have restored adequate distal circulation in 27 patients in whom improvement of the visceral or peripheral ischemia was observed after the thoracic aortic repair. Additional procedures (immediately after the thoracic repair or later) were necessary in 15 patients to restore adequate perfusion in the compromised area.(ABSTRACT TRUNCATED AT 250 WORDS)
