Abstract
Objective: to evaluate the function of baroreceptors in patients after different types of surgical correction of hypoplastic aortic arch.
Materials and methods: In this prospective cohort study evaluated the results of surgical treatment of 54 patients who underwent surgical treatment for aortic coarctation. The patients were divided into two groups according to the method of correction of the defect: reconstruction with the use of a modified reverse plasty of LPA (group I, n=27) and reconstruction using the "extended" anastomosis (group II, n=27 patients).
Results: the Postoperative period of observation was 25 (21-30) months. Spontaneous sensitivity of the baroreceptors differed between groups and was significantly higher in group II is 11.6 (10,5; 12,6) vs 9,1 (8,2;10,1) in group I, p -0,04. The velocity of pulse blood flow was also higher in group II 7,7 (5,8;9) (m/s) -1 compared to 6.5 (5,4;7,1) (m/s) -1 in group I and differed between groups P – 0,04.
Conclusions: Reduced sensitivity of baroreceptors in patients after a modified reverse plastic of the left subclavian artery may be regarded as the method of choice in patients with coarctation and hypoplasia of the arch as a method of reducing the frequency of arterial hypertension in the late postoperative period
