• To determine the impact of intraoperative autotransfusion on vascular surgical care, data related to 304 major vascular surgical operations performed over a 42-month period were retrospectively analyzed. Procedures included abdominal aortic aneurysmectomy (N 152), aortobilateral femoral bypass (N = 64), thoracoabdominal aortic aneurysmectomy (N = 20), and other vascular procedures (N = 68). Fifty percent of the transfusion requirement was met by autotransfusion for the average patient. The per patient average volumes (liters) autotransfused were as follows: elective abdominal aortic aneurysmectomy, 0.87 L and nonelective, 1.45 L; elective aortobilateral femoral bypass, 0.63 L; elective thoracoabdominal aortic aneurysmectomy, 2.47 L, and nonelective, 2.15 L; and elective other, 0.53 L and nonelective, 1.30 L. Results of immediate postoperative and hospital discharge hemoglobin, hematocrit, and coagulation studies (prothrombin time, partial thromboplastin time, and platelets) did not differ from results of preoperative studies in any group. Neither mortality nor morbidity was related to intraoperative autotransfusion. These data suggest that intraoperative autotransfusion is a safe blood replacement method during major vascular surgical operations.
