ABSTRACT
We present the outcome of surgical management for thoracoabdominal aneurysms in 27 patients during the past 22 years. Ischemia of visceral organs was successfully prevented by axillo-femoral temporary bypass using a 10mm PTFE graft with an 8mm branch for main visceral vessels and partial extracorporeal circulation perfusing visceral organs. No other significant problems were encountered. Paraplegia occurred in 5 patients (18.5%). Three of them had received reconstruction of the intercostal arteries. Patients treated by spinal fluid drainage developed no paraplegia. The Crawford inclusion and Piehler bypass techniques were useful in reconstructing the main visceral vessels. Two patients died of ruptured proximally anastomosed thoracic aorta after a thromboexclusion technique. Early death occurred in three patients and late death in one.
