OBJECTIVE: The objective of this study was to report current transfusion requirements and outcomes in @entity1 undergoing elective aortic surgery with autologous transfusion. METHODS: This was a retrospective review of transfusion practice in infrarenal aortic surgery in a tertiary vascular unit with a longstanding interest in autologous transfusion. One hundred and ten consecutive @entity1 underwent infrarenal aortic surgery with a combination of acute normovolemic hemodilution (ANH) and @entity1358 ( @entity1358 ). All @entity1 underwent hemodilution to a target hemoglobin concentration of 11 g/dL and underwent @entity1358 with a centrifugal device. RESULTS: Median @entity190 was 1140 mL (interquartile range [IQR], 683 to 1609 mL) in 78 @entity439 repairs and 775 mL (IQR, 400 to 1225 mL) in 32 aortobifemoral bypasses for occlusive disease (P =.02), resulting in a median salvaged red cell volume of 403 mL (IQR, 256 to 563 mL) for @entity439 repairs and 250 mL (IQR, 200 to 290 mL) in bypass surgery (P =.001). Thirty-six @entity1 (33%) needed transfusion of stored blood, for a total of 115 units, with just four @entity1 needing more than five units. The mortality rate was 8% (9/110). With multivariate analysis, low hemoglobin level (P =.006) and low platelet count (P =.023) were associated with stored blood transfusion. CONCLUSION: @entity190 is too small to justify @entity1358 in surgery for occlusive disease; ANH alone may be a suitable strategy. With appropriate experience, the combination of ANH and @entity1358 may render crossmatching unnecessary, even in aortic @entity439 surgery.
