Factors That Affect the Survival Rate of Ruptured Abdominal Aortic Aneurysm

ABSTRACT

PURPOSE: Ruptured abdominal aortic aneurysm (RAAA) continue to be a significant causes of death. We review 14 patients who underwent repair of RAAA to analyze the factors affecting the mortality rate. METHOD: Fourteen patients who underwent repair of a RAAA at Samsung Medical Center from March 1995 to July 2001 were reviewed retrospectively. The patients were divided two groups as survival and fatal group. Data was analyzed by both univariate and multivariate analysis. RESULT: There were nine patients (64%) in survival group and five patients (36%) in fatal group. The mean age of survival group was 64.67+/-19.59 years and 67.0+/-5.15 years in fatal group. All patients in fatal group were died within 2 days postoperatively. By univariate analysis of various factors associated with the mortality rate, creatinine level, hemoglobin level were statistically significant. Other factors associated with the mortality rate, albumin, initial systolic blood pressure, initial diastolic blood pressure, operation time, prothrombin time and perioperative platelet count were not statistically significant. CONCLUSION: These findings suggest that creatinine level is predictive of death in repair of RAAA. But patients who have RAAA should not be denied therapy on the basis of any specific criteria of preoperative factors.
