Pituitary apoplexy following coronary artery bypass grafting

Abstract

Pituitary apoplexy usually results from ischemic or hemorrhagic changes due to preexisting adenomas of the pituitary gland. Rarely, it can occur after surgical procedures, mainly because of severe hemorrhage or hypotension. It is a serious condition and may lead to disastrous complications and even to death. We present a 60-year-old male patient in whom pituitary apoplexy developed due to protamine anaphylaxis during coronary artery bypass surgery.
