The article describes a clinical case - the resection of the hormone- active tumor of the carotid glomus. The hormonal activity of the tumor was suspected based on data of the patient's history, (malignant arterial hypertension with sharp rises in arterial tension, episodes of the increased arterial tension during mechanical impact on the tumor) and hemodynamic parameters during surgery (heart rhythm disturbances after induction of anesthesia and pronounced hypertensive reactions when manipulating the tumor tissue). The article reviews publications on anesthetic support during the resection of hormone-active chemodectomas.Detection of typical clinical signs such as hypertension, tachycardia, fever, headaches, etc. in the history of patients with chemodectoma may suggest hormonal activity of the tumor. Biochemical tests that determine the level of catecholamines and their breakdown products can confirm the diagnosis. When planning surgery, the anesthesiologist should be prepared for the development of the relevant complications. Hypertension, as the most frequent complication, should be prevented by preoperative adrenergic blockers and treated intraoperatively with short-acting antihypertensive drugs. After exclusion of the tumor from the bloodstream, it is necessary to prepare for the development of hypotension.
