XXXX following operations on the abdominal aorta.

@entity2759 following operations on the abdominal aorta is considered an unpredictable event attributable to variations in spinal cord blood supply. Our experience with seven cases of @entity2759 contradicts this hypothesis. All @entity1 had a bifurcation graft implanted. Three @entity1 had bilateral interruption of hypogastric circulation. Each had @entity39 and two had left @entity63 . Two @entity1 had unilateral hypogastric ligation. In both of these @entity1 , early @entity551 preceded recognition of @entity2759 . Two @entity1 without known interruption of hypogastric flow had proximal side-to-end anastomoses placed in an @entity1856 aorta. Intraoperative @entity1897 occurred in one and @entity86 occurred in the other @entity1 . In the latter case @entity2759 occurred late concomitantly with embolization. The surmised important details in @entity1 ' courses with @entity2759 are (1) interference with pelvic blood flow (five of seven @entity1 ) severe enough in three cases to cause @entity39 and (2) a high incidence of perioperative complications. Interruption of an anomalous spinal artery was probably not a factor as @entity602 were mostly distal and no case of @entity2759 occurred after a cylinder graft was placed. @entity2759 is potentially preventable. Our experience reemphasizes the importance of hypogastric perfusion, the dangers of handling the @entity1856 aorta, and the necessity for avoiding @entity551 .
