title: Presentation of undiagnosed pheochromocytoma during coronary artery bypass surgery.
abstract: Hypertension and tachyarrhythmias arising during an operative procedure are rarely caused by an unsuspected pheochromocytoma. However, when this tumor becomes clinically manifest under general anesthesia during a procedure for an unrelated condition, the mortality is high. An unusual case of a patient who developed episodes of catastrophic hypertension and tachyarrhythmias while undergoing a coronary artery bypass procedure is described. The subject of undiagnosed pheochromocytoma becoming clinically manifest under general anesthesia is discussed with a pertinent review of the literature.
