Risk Factors for the Development of Renal Failure Following the Surgical Treatment of Traumatic Aortic Rupture

A retrospective study of 44 patients who were treated surgically for traumatic aortic rupture was undertaken to determine risk factors for the development of postoperative renal failure. Renal failure occurred in 11 of 41 patients (27%) eligible for analysis. The Pearson product-moment correlation showed no significant relationship between the occurrence of renal failure and the patient's age, injury severity score, initial blood pressure, or the interval between accident and thoracotomy. Renal failure was significantly correlated with cross-clamping only (r = .2751, p = .043). There was no relationship between renal failure and total cross-clamp times. The mortality rate was significantly higher for patients with renal failure.
