Surgical treatment of pararenal abdominal aortic aneurysms.
Thirty patients with juxtarenal infrarenal and 16 patients with suprarenal abdominal aortic aneurysms underwent elective (58%) or urgent (42%) repair. Twenty-three patients were hypertensive and 20 had impaired renal function preoperatively. Nineteen patients required combined aortic and renal artery reconstruction, in which reimplantation was the most common technique used. The perioperative mortality rate was 7.4% in the elective group and 36.8% in the urgent group. Rupture of the aneurysm and a preoperative high serum creatinine level were risk factors correlating to early mortality. Among survivors, 61% showed a rise in serum creatinine in the early postoperative period. In all but one the transient renal insufficiency was resolved within one month. Of the hypertensive patients 64% were cured or under control with medication following combined reconstruction. These results demonstrate that surgical repair of pararenal abdominal aortic aneurysms can be performed with an acceptable mortality and morbidity.
