Adventitial stripping for carotid sinus syndrome

Abstract

Patients with a carotid sinus syndrome (CSS) suffer from spells of dizziness and loss of conscience due to an exaggerated carotid baroreflex response. Three types of the syndrome are described: cardioinhibitory, vasodepressor and a mixed form. The gold standard for treatment is insertion of a pacemaker, but this therapy may be effective only in a pure cardioinhibitory type. In contrast, surgically interrupting afferent nerves at the origin may offer relief of symptoms in all three types. The present review analyzes the results of a surgical technique termed "adventitial stripping" of the carotid sinus. Data from 130 procedures demonstrate that carotid denervation is effective in 85% of CSS cases with low complication rates. Postoperative monitoring is mandatory as transient alterations in blood pressure and heart rate may occur.
