Blood pressure regulation in pheochromocytoma.
Two sets of studies were performed in 13 patients with proved adrenal pheochromocytoma to test the hypothesis that the sympathetic nervous system (SNS) is active and might contribute to the hypertensive state. Similar studies were performed in 15 additional patients considered to have essential hypertension. In the first set, 13 patients with pheochromocytoma were subjected to head-up tilt to a...
متن کاملPheochromocytoma Crisis With Severe Cyclic Blood Pressure Fluctuations in a Cardiac Pheochromocytoma Patient Successfully Resuscitated by Extracorporeal Membrane Oxygenation
Cardiac pheochromocytoma is relatively rare. Few reports describe the intraoperative and postoperative progression of patients experiencing a life-threatening pheochromocytoma crisis treated with extracorporeal membrane oxygenation (ECMO).A 35-year-old man was referred to our facility for paroxysmal hypertension with a 10-year history of sweating, headaches, cardiac palpitations, and postexerci...
متن کاملUndiagnosed pheochromocytoma: the anesthesiologist nightmare.
A male, 62 years of age, presented to the operating room for the removal of a right adrenal mass. Induction of anesthesia triggered a severe hypertensive crisis resistant to high doses of nitroprusside, nitroglycerin and labetalol. The crisis was ultimately resolved with the administration of 5 mg bolus of phentolamine. Surgery was canceled, the patient was transported to the intensive care uni...
متن کاملRapid cyclic fluctuations of blood pressure associated with treatment of pheochromocytoma by labetalol.
Rapid cyclic fluctuations of blood pressure in patients with a pheochromocytoma have rarely been reported. The suitable conditions to induce this phenomenon are not adequately known. We report here a patient with an adrenal pheochromocytoma who showed this phenomenon after oral administration of labetalol.
متن کاملRapid cyclic fluctuations of blood pressure associated with an adrenal pheochromocytoma.
We present a patient with an adrenal pheochromocytoma with an unusual pattern of periodic alternating hypertension and hypotension. Alpha-adrenergic blockade alone failed to affect this pattern, which was abolished only after fluid repletion. The efficacy of volume expansion in ultimately correcting the wide fluctuations of blood pressure implicates a possible reflex neurogenic mechanism for th...
