Abstract

PURPOSE
Abdominal aortic aneurysm is a complex disease that has too many clinical manifestations for classifying these patients as the ruptured and nonruptured groups. To evaluate the effect of the patients preoperative status to the surgical outcomes, the authors classified the abdominal aortic aneurysm patient's into four groups according to their preoperative status and we studied their outcomes. METHOD: Between 1992 and 2004, 117 patients underwent abdominal aortic surgery. Among the patients, 47 asymptomatic abdominal aortic aneurysm patients were classified as group I. 34 abdominal aortic aneurysm patients with abdominal pain were classified as group II. 20 ruptured abdominal aortic aneurysm patients without hemodynamic instability were classified as group III. 16 ruptured abdominal aortic aneurysm patients with hemodynamic instability were classified as group IV. We then analysed their clinical outcomes retrospectively. RESULT: Group IV received the highest number of transfusions and they showed the highest incidence of postoperative ARDS and the highest mortality rate. Group III received more transfusions and they showed a higher incidence of ARDS than Group I and II, but they had the lowest mortality rate. There were no significant differences in the transfusion amount, complication and mortality between Group I and II.
CONCLUSION
Massive transfusion causes postoperative ARDS and multiorgan failure and this causes death for patients with ruptured abdominal aortic aneurysm. Preoperative hemodynamic instablity is a definite factor for massive transfusion, whitch causes ARDS and death.
