Technical and pharmacologic management of @entity551 during repair of XXXX .

@entity16 can occur in the postoperative period of @entity1498 repair, @entity63 being the pathogenic factor most likely to be involved. This study was designed to evaluate the extent of the hemodynamic changes proximal and distal to the @entity1498 at the time of cross-clamping, as well as the effects of @entity30049 and @entity3044 upon the hemodynamic changes. Included in the study were 17 @entity1 with adult type coarctations who had dual hemodynamic monitoring. During cross-clamping, there was an increase in the gradient between proximal and distal pressures, with severe @entity551 (< 50 mm Hg) occurring in six @entity1 . @entity3044 corrected the @entity551 in five @entity1 , but the sixth required a surgical shunt. @entity30049 was effective for the treatment of proximal @entity101 ; however, it also decreased distal pressure. The ligation of collateral vessels was associated with a decrease in distal pressures as well. During cross-clamping, pentolinium was useful for the management of proximal @entity101 and @entity3044 increased the distal pressures in some of the @entity1 who presented @entity551 . However, because of the difficulties in predicting the individual response, their administration would be best guided by dual pressure monitoring. It is postulated that the recognition and proper treatment of @entity551 may be an important factor in the prophylaxis of @entity260 .
