Pituitary apoplexy following cardiopulmonary bypass: considerations for a staged cardiac and neurosurgical procedure

Pituitary apoplexy in a pre-existing pituitary tumor can result in serious and permanent neurologic deficits following cardiac surgical procedures. Several factors related to the altered physiology of cardiopulmonary bypass (CPB) contribute separately or in combination to the development of this syndrome. Over the last year we have encountered two such cases in whom emergency and prompt decompression of the adenoma resulted in an improvement of the initial clinical presentation but nevertheless persistence of residual and devastating ocular manifestations. In the literature six similar cases have been reported following cardiac surgical procedures, with similar outcomes. In this report we describe our experience and management of these two patients, and that published in the literature. We propose a possible role for a staged cardiac and neurosurgical procedure as a prophylactic measure in patients with known pituitary tumor. The role of cerebral monitoring is also discussed.
