Objectives: This study was designed to evaluate the surgical treatment of recurrent coarctation by a new technique.
Background: Recurrent coarctation either from aneurysm or recurrent constriction is a difficult problem in the adult because of the possible interruption of important collateral circulation.
Methods: We reviewed four patients who underwent recurrent coarctation surgery with the use of deep hypothermic circulatory arrest (HCA).
Results: All four patients survived. Deep HCA facilitated precise surgical resection and there was no postoperative paraplegia, stroke, or myocardial infarction.
Conclusions: Deep HCA and resection and grafting of the coarctation is indicated for complicated adult coarctations, particularly when the collateral circulation is in doubt.
