Pheochromocytoma Crisis Rescued by Veno-Arterial Extracorporeal Membrane Oxygenation and Continuous Renal Replacement Therapy

Pheochromocytoma is a rare catecholamine producing adrenal tumor. Pheochromocytoma crisis is a life-threatening condition inducing multiple organ failure and hemodynamic instability caused by too much catecholamines produced from pheochromocytoma. We report a 59-year-old woman with pheochromocytoma crisis rescued by veno-arterial extracorporeal membrane oxygenation (VA-ECMO), continuous renal replacement therapy (CRRT), and interval tumor resection. In June 2020, the patient was taken to our institution complaining of headache and left lower back pain. The patient developed cardiopulmonary arrest while at the emergency department. After extracorporeal cardiopulmonary resuscitation, the patient required VA-ECMO for hemodynamic support, and subsequently CRRT for catecholamine removal and acute kidney injury. After 1 month of hemodynamic management, the patient underwent left adrenalectomy. The postoperative course was uneventful and she was discharged on postoperative day 23. CRRT would be a safe and feasible option for catecholamine control in patients with acute kidney injury in pheochromocytoma crisis.
