The key to successful surgical resection of a pheochromocytoma is adequate preparation of the patient. Ideally, at least 2 to 3 weeks of antihypertensive treatment should be given before surgery. Patients first should be given an α-blocker for at least 10 days before the surgery to control high blood pressure. After the α-blocker is started, a ß-blocker can be added for the control of the heart rate and any arrhythmia. Methimazole is given to patients with hyperthyroidism, and steroids are given to patients with Addisons disease.2
