Hypopituitarism following coronary artery bypass surgery.

Coronary artery bypass surgery (CABS) is a common operation, which is often complicated by neurological sequelae. Disturbances of cerebral blood flow have been reported up to eight days after surgery and pituitary apoplexy has previously been reported. We report a case of hypopituitarism without pituitary apoplexy, which developed after a period of sustained arterial hypotension, during coronary artery bypass surgery.
