Influence of carotid body tumor resection on the blood pressure in essential hypertensive patients

Objective To study the effect of CBT resection on blood pressure in essential hypertensive subjects. Methods Clinical data of 24 essential hypertensive patients (BP >140/90 mmHg or was using anti-hypertensive drugs) with CBT resection from May 2005 to March 2016 was analyzed , retrospectively. The heart rate, blood pressure were recorded continuously during the peri-operative and follow-up period. All of the patients were followed-up for at least 1 year. Results The systolic blood pressure(SBP) and pulse pressure (PP) decreased 1-3 months after the operation, and the difference was significant (P 0.05). Postoperative patients used less amount of antihypertensive drugs, but the difference was statistically not significant (P>0.05). Conclusions Unilateral CBT resection is associated with short-term to intermediate-term lowering of BP in hypertensive patients (P>0.05).
