Background. We investigated the correlation bet-ween perioperative variables such as patients’ age and vital organ function after operation on thoracic aorta using deep hypothermic circulatory arrest (DHCA).
Methods. Ninety-five patients who underwent replacement of thoracic aorta under DHCA for acute or chronic aortic dissection and aortic aneurysm, and survived more than 10 days were divided into group I (age less than 60, n=17), group II (between 60 and 69, n=39), and group III (over 70, n=39). Concomitant procedures such as aortic root replacement and coronary artery bypass grafting were performed in 9, 4, and 1 patients in group I, II, and III, respectively. Postoperative pulmonary, renal, and hepatic function within 10 days were compared. Correlation between other perioperative variables and organ function was also investigated among all 95 patients.
Results. Postoperative pulmonary, renal, and hepatic function in group III was not significantly inferior to those in groups I and II. The operation time, and amount of red blood cells and fresh frozen plasma used during operation, were significantly greater in group I, which showed an intimate correlation to significant elevation of hepatic enzymes.
Conclusions. Although lower functional reserve of vital organs in the elderly patients was predicted, they showed an acceptable functional recovery after operation with DHCA. Other perioperative variables such as operation time and blood transfusion showed a negative impact on postoperative hepatic function.
