All patients with abdominal or thoraco-abdominal aneurysms treated at the Vascular Service of the University of Natal were reviewed. Aneurysms extended above the renal arteries in 15 % of patients (140 patients), of these 71 originated in the thoracic aorta. The aneurysms were resected or excluded and the diseased aorta and major branches reconstituted with prosthetic grafts, through bilateral subcostal or eighth interspace thoraco-abdominal incisions. Local 4�C hypothermic Ringer's lactate infusions into the renal, coeliac and superior mesenteric arteries were used for visceral organ protection. In addition, intravascular mannitol, calcium channel blockers, steroids, anti-endotoxin serum and intrathecal papaverine with cerebrospinal fluid drainage were introduced during the period of review.
