Why the study?
Pheochromocytomas secrete catecholamines leading to diverse symptoms, making accurate diagnosis and appropriate treatment selection crucial for favorable outcomes.
The combination of ECMO and IABP can effectively stabilize hemodynamics in patients with pheochromocytoma-induced cardiogenic shock, enabling definitive surgical treatment.
May temporize refractory PHEO shock for diagnosis and resection; leaves open whether combined ECMO-IABP is preferable to ECMO alone.
BACKGROUND: Pheochromocytoma (PHEO) is a type of tumor that originates from chromaffin cells in the adrenal medulla and is classified as an adrenal paraganglioma. PHEOs can secrete catecholamines, leading to a variety of symptoms. Accurate diagnosis and appropriate treatment selection are crucial for favorable outcomes in these cases. CASE SUMMARY: The patient presented with unexplained chest tightness, palpitations, and pink sputum. Upon examination and analysis of laboratory results, a diagnosis of adrenal PHEO was established. The PHEO secreted high levels of catecholamines, causing sudden fluctuations in blood pressure and heart rate, leading to extremely unstable hemodynamics. Treatment with extracorporeal membrane oxygenation and intra-aortic balloon counterpulsation helped stabilize the patient's vital signs, allowing for timely surgical intervention. CONCLUSION: The combination of extracorporeal membrane oxygenation and intra-aortic balloon counterpulsation can enhance tissue perfusion, thus providing a solid foundation for the accurate diagnosis and effective surgical treatment of PHEO.
