Abstract:
From 1978 through 1992, 103 patients (mean age: 69 years) underwent elective repair of abdominal aortic aneurysm (eAAA) at our institute. One or more postoperative complications occurred in 30 patients (29%), with mortality rate of 1.9%. Factors significantly associated with postoperative complications by univariate analysis included male sex (p=0.0082), operation time (p=0.0006), size of aneurysm (p=0.0045), blood loss during operation (p=0.0037), decreased pulmonary function (p=0.0155), and the number of platelet counts (p=0.0468). Simple linear regression analysis showed that there was a significant correlation among AAA size, operation time and blood loss. Age at operation, however, did not have any influence on morbidity and mortality. Complete survival information was obtained in 96 (follow up rate of 95%) patients, and the influence of preoperative risk factors on late survival was also examined by the Kaplan-Meier method. Factors influencing long-term survival were renal dysfunction and age at time of operation.
