Extract

The dramatic reduction in surgical mortality associated with repair of congenital heart anomalies in recent decades has been accompanied by a growing recognition of adverse neurologic sequels in some of the survivors. Abnormalities of the central nervous system may be a function of coexisting cerebral abnormalities or acquired events unrelated to surgical management (such as paradoxical embolus, cerebral infection, or effects of chronic cyanosis), but insults to the central nervous system appear to occur most frequently during or immediately after surgery. In particular, techniques of support used during neonatal and infant cardiac surgery—cardiopulmonary bypass, profound hypothermia and circulatory arrest—have been implicated as important causes of cerebral injury. This paper will review the effects of bypass and deep hypothermic circulatory arrest on neurodevelopmental outcome.
