Treatment of Hereditary Pheochromocytoma with Small Tumors After Contralateral Complete Adrenalectomy
Clinical Scenario
This protocol addresses selected patients with hereditary pheochromocytoma who present with small tumors and have already undergone a contralateral complete adrenalectomy. In this context, preserving adrenal cortical tissue is a central surgical consideration to prevent permanent adrenal insufficiency.
Treatment Approach (Partial Overview)
For patients with a hormonally functional tumor, management includes structured preoperative adrenergic blockade, with a specific class of receptor-blocking agents used as the first-line choice. This preparation also incorporates targeted dietary and fluid measures aimed at reversing catecholamine-related volume changes ahead of surgery.
The complete regimen — including sequencing, agent selection, duration, and perioperative management — is available in the full protocol.
Treatment Targets
Successful preoperative preparation aims for a blood pressure below 130/80 mmHg while seated and above 90 mmHg systolic when standing, with a heart rate of 60–70 bpm seated and 70–80 bpm standing.

We suggest partial adrenalectomy for selected patients, such as those with hereditary pheochromocytoma, with small tumors who have already undergone a contralateral complete adrenalectomy to spare adrenal cortex to prevent permanent hypocortisolism.
We recommend that all patients with a hormonally functional PPGL should undergo preoperative blockade to prevent perioperative cardiovascular complications.
We suggest α-adrenergic receptor blockers as the first choice.
Treatment should also include a high-sodium diet and fluid intake to reverse catecholamine-induced blood volume contraction preoperatively to prevent severe hypotension after tumor removal.
Based on retrospective studies and institutional experience, a target blood pressure of less than 130/80 mm Hg while seated and greater than 90 mm Hg systolic while standing seems reasonable, with a target heart rate of 60–70 bpm seated and 70–80 bpm standing.
