title: [The role of chronic renal insufficiency in the prognosis of surgical interventions in subrenal abdominal aortic aneurysm].
abstract: Chronic renal insufficiency is one of the most important factors governing the immediate and long-term outcome after aneurysm repair. A total of 484 patients with abdominal aortic aneurysm (A.A.A.) have undergone elective surgical treatment in our Institution during the last 5 years. Of these, we selected 60 patients; 30 with a normal serum creatinine concentration and 30 with preoperative renal insufficiency (serum creatinine concentration greater than 2 mg/dl). In this second group, 23 patients (76.6%) were affected by slight or median renal insufficiency, 5 patients (16.6%) were affected by severe renal insufficiency (creatinine concentration greater than 4.5 mg/dl), and 2 patients (6.6%) had complete renal failure with dialytic treatment from 1.5 and 2 years respectively. We analyzed postoperative renal function in all 60 patients. In the first group, only 6 patients (20%) showed a transient renal insufficiency, without mortality and morbidity. In the second group, postoperative complications and mortality tended to occur more frequently in patients with a severe renal insufficiency than in patients with slight or median insufficiency or complete renal failure. The present data suggest that dialytic treatment might be necessary in patients with severe renal insufficiency before aneurysm repair.
