The Influence of Preexistent Renal Failure on the Prognosis Following Ruptured Abdominal Aortic Aneurysms

Abstract

Purpose : The aim was to verify the relation between renal failure (RF) and prognosis following surgery for ruptured abdominal aortic aneurysm (RAAA).
Methods : Among thirty-nine patients were diagnosed as having an RAAA and 33 patients received graft replacement. Perioperative factors were compared between non-survivors and survivors in patients receiving graft replacement.
Results : The mortality rate was 38% (15/39) in all patients and 27% (9/33) in patients receiving graft replacement. The preoperative serum creatinine (Cr) level was significantly (p<0.05) higher (2.3±0.5 vs 1.3±0.1 mg/dl) and systolic BP on arrival was significantly lower (71.7±5.3 vs 93.4±6.6 mmHg) in non-survivors than in survivors, respectively. There were significantly more patients with past cardiopulmonary resuscitation in non-survivors (4/9) than in survivors (1/24). The amount of intraoperative urine volume were significantly smaller in non-survivors (98±28 ml/hr) than in survivors (156±23). Postoperative renal failure which required hemodialysis was significantly more frequent in non-survivors (4/9) than in survivors (0/24).
Conclusions : RF was associated with the prognosis following surgery for RAAA. The level of preoperative Cr would be a predictive marker.
