Key result
VA-ECMO successfully supports cardiogenic shock from pheochromocytoma crisis, enabling rapid LVEF improvement and weaning.
Why the study?
Pheochromocytoma during pregnancy presents clinical challenges including cardiogenic shock requiring advanced support such as VA-ECMO.
Case Report (n=1)
VA-ECMO can be successfully used as a bridge to recovery in peripartum cardiogenic shock induced by pheochromocytoma crisis.
Consider pheochromocytoma in refractory postpartum cardiogenic shock; this case extends the differential but leaves management questions open.
We describe a 37-year-old multiparous woman with cardiogenic shock resulting from pheochromocytoma crisis. She had term labor induction after developing hypertension attributed to preeclampsia. Severe hemodynamic instability followed on postpartum day 2 requiring venoarterial extracorporeal membrane oxygenation (VA-ECMO). Suspicion for pheochromocytoma arose after a computed tomography scan showed a large adrenal mass, and the diagnosis was confirmed with plasma and 24-hour urine metanephrine levels. She initially had cardiomyopathy with left ventricular ejection fraction less then 10%, which rapidly improved, and she was successfully weaned off VA-ECMO. This patient case illustrates the clinical challenges concerning pheochromocytoma during pregnancy.

Saiki et al. (2022) conducted a case report in Cardiogenic shock resulting from pheochromocytoma crisis (n=1). Venoarterial extracorporeal membrane oxygenation (VA-ECMO) was evaluated on Clinical recovery and weaning from VA-ECMO. Venoarterial extracorporeal membrane oxygenation successfully supported a 37-year-old woman with cardiogenic shock from a pheochromocytoma crisis, leading to rapid LVEF improvement and weaning.
