Acute XXXX of the aortic isthmus: repair with cardiopulmonary bypass.

@entity1 @entity602 @entity1504 @entity397 @entity358 @entity451
In an attempt to prevent @entity451 , a devastating complication common after the repair of @entity397 of the aorta, we have used partial cardiopulmonary bypass. Most of the @entity1 in our series (79.5%) underwent other major surgical procedures immediately before or after the aortic repair. Eight of the 110 @entity1 died before aortic repair could be performed. The aorta was not repaired in 3, because of other injuries. In 9, the repair was done without a shunt or bypass; 4 @entity1 died and 2 (22.2%) survived without @entity451 . One of the 2 who underwent repair with a Gott shunt died; the survivor suffered no @entity602 . Of the 88 @entity1 whose repair was carried out under cardiopulmonary bypass, 6 died and 80 (90.9%) survived without @entity451 . None of the last 39 @entity1 has become paraplegic, as vasodilator treatment is now discontinued during the cross-clamp period. Serious @entity1504 was present in 19 @entity1 ; in 3 (15.8%) the injury became worse after repair. There was no evidence of new or increased intraabdominal bleeding during heparinization. Except in the event of @entity358 , systemic heparin therapy was not associated with major problems.
