XXXX after aortic surgery. The role of laparotomy to rule out @entity292 .

@entity1 @entity548 @entity344 @entity292 @entity360
The frequency and causes of @entity360 occurring after aortic surgery were evaluated retrospectively to determine the incidence of @entity292 ( @entity292 ) in relation to other causes and to place in perspective the role of laparotomy for the diagnosis of @entity292 . Two hundred fifty-three @entity1 in whom aortic prostheses have been inserted were observed for a mean of 46 months. Seventy-four @entity548 episodes occurred in 21% of @entity1 between 1 and 108 months after surgery (mean 29 months). Only one @entity292 appeared that was associated with @entity360 , for an incidence of 1.4% of @entity548 episodes and 0.4% of grafts inserted. No diagnostic workup for @entity360 was performed for 20 of the 74 episodes and no AEFs were noted in this group during a mean follow-up of 28 months. Diagnostic evaluation was done for the remaining 54 episodes. No cause for @entity548 was identified in 16 @entity1 and no @entity292 developed in this group during a mean follow-up of 26 months. A potential @entity548 site was identified in 38 @entity1 , of whom 30 had @entity344 and no subsequent evidence of @entity292 during a mean follow-up of 28 months. Laparotomy for a suspected @entity292 was recommended for the remaining eight episodes in eight @entity1 and was performed in six @entity1 . An @entity292 was seen in one @entity1 with abnormality found on preoperative CT scanning; an @entity344 was identified in three @entity1 ; and no pathologic condition was found in the remaining two (negative laparotomy rate, 33%).(ABSTRACT TRUNCATED AT 250 WORDS)
