ABSTRACT
Surgery for abdominal aortic aneurysms (AAA, <i>n</i>=240) was reviewed in subgroups of ruptured AAA (RAAA, <i>n</i>=31), non-ruptured AAA with arteriosclerosis obliterans (AAA w/ASO, <i>n</i>=48), and non-ruptured AAA without ASO (AAA w/o ASO, <i>n</i>=161). The average follow-up period was 4.2 years (maximum 15.8 years) and the follow-up rate was 97%. Overall operative mortality rates were 41.9% in RAAA and 2.9% in non-ruptured AAA. Those were 6.3% in AAA w/ASO and 1.9% in AAA w/o ASO. The main causes of death in the long-term follow-up period were heart disease in 32%, malignant neoplasm in 22%, cerebrovascular accidents in 10% and renal failure in 10%, and miscellaneous. Only renal failure was related to operative risk factors. Relative survival rates excluding hospital death following surgery were 79% at 5 years and 0% at 10 years in RAAA; 74% at 5 years and 52% at 10 years in AAA w/o ASO; 95% at 5 years and 78% at 10 years in AAA w/ASO; 90% at 5 years and 70% at 10 years in non-ruptured AAA. These survival rates were lower than those found in the normal population, especially in AAA w/ASO. AAA w/ASO had more surgical risk factors of ischemic heart diseases and diabetes mellitus. Main causes of deaths were heart diseases, and renal failure during the long-term follow-up period was more predominant in AAA. It is important to follow all patients after surgery for AAA with special attention to heart disease and renal failure.
