Renovascular Hypertension Associated with Pheochromocytoma: A case report / 대한마취과학회지

ABSTRACT

The coexistence of pheochromocytoma and renal artery stenosis has been recognized since 1958, but it is rare. We have experienced an anesthetic management of 43-year-old female patient of renovascular hypertension associated with right adrenal pheochromocytoma. Proper preoperative preparation, sufficient sedation, smooth induction, complete analgesia and good muscle relaxation were very important. Relative cardiovascular stability was achieved with sodium nitroglycerine, sodium nitroprusside and verapamil during tumor manipulation. After the tumor was removed, we could control the hypotension with dopamine, dobutamine, crystalloid and colloid. On the operative field there was no definite anatomic stenosis of renal artery and it was suggested that leakage of catecholamines from pheochromocytoma causes functional, reversible spasm of renal artery and thus renovascular hypertension.
