Experience with circulatory arrest and hypothermia to facilitate thoracic aortic surgery.

摘要

A total of 12 patients underwent surgical repair for thoracic aortic dissections with a technique which included cardiopulmonary bypass, profound hypothermia, high-dose thiopentone and circulatory arrest. Seven of nine early postoperative survivors made a complete recovery on clinical criteria. There were three perioperative deaths and there was one late postoperative death from chronic renal disease. There were no deaths among those operated on electively. Neuropsychological testing may help to define the consequences of circulatory arrest on higher function.
