Surgical Treatment of Aortic Stenosis Combined with Bilateral Pheochromocytomas in a Dialysis Patient

: We report a case of a dialysis patient with severe aortic stenosis(AS) along with bilateral pheochromocytomas. A 52-year-old man presented with syncope and was diagnosed with severe AS. Although aortic valve replacement(AVR) was scheduled, bilateral pheochromocytomas were found during preoperative examination. There was a high possibility of developing hemodynamical crisis during AVR, and we planned to perform adrenalectomy prior to AVR. To avoid circulatory collapse just after adrenalectomy, balloon aortic valvuloplasty (BAV) was performed beforehand. Two weeks after the adrenalectomy, AVR was performed in a stable condition.
