Coronary bypass surgery in the presence of metastatic pheochromocytoma.

The hemodynamic management of a patient with a pheochromocytoma presents special challenges due to the episodic release of catecholamines from the tumor, which threatens to provoke a hypertensive crisis. We present a patient with metastatic pheochromocytoma (bone, lung, lymph nodes) who underwent successful coronary artery bypass graft (CABG) surgery following premedication with phenoxybenzamine and metyrosine as well as the use of intraoperative phentolamine for the management of a hypertensive crisis in the operating room.
