Thoracoabdominal aortic reconstruction distal to the left subclavian artery was carried out on 19 patients between 1974 and 1990. Screening procedures to detect cardiac, respiratory or renal impairment were undertaken in all patients. Reconstruction was in the upper third of the descending aorta in 6 patients, middle third in 6 patients, and lower third in 7 patients. The Crawford inclusion technique was used in all cases. There were six deaths, four of which were from the high reconstruction group, and one each from the middle and lower group. Paraparesis occurred in 4 patients, 2 of whom survived with some impairment. Temporary renal failure was seen in 2 patients, liver failure in 2, respiratory failure in 2, sepsis in 1, myocardial infarction in 1, and severe coagulopathy in 3. The perioperative mortality rate was 32% for the group as a whole and 15% for reconstructions which started at the middle or lower thoracic level. We conclude that the mortality rate for the middle and lower reconstructions is acceptable but that alternative techniques for the high aneurysms should be sought.
