Abstract

Aim: To assess the changes in the elastic properties of the aorta during different follow-up period in patients underwent coarctation repair using a modified reverse left subclavian artery flap plasty and extended end-to-end anastomosis. Materials and methods: This was a prospective randomized study of the 54 patients underwent repair of coarctation of the aorta. Patients were divided in 2 groups depending on the correction type: reconstruction using the modified reverse left subclavian artery flap plasty (I group, 27 pts) or extended end-to-end anastomosis (II group, 27 pts). The 2 parameters were assessed in all patients – extensibility of the aortic wall and index of the aortic wall rigidity. Results: The statistically significant differences were found between two groups during the follow-up period (6, 12, 24 months). In the I group elastic properties were higher and index of the aortic wall rigidity was lower than in the II group. Conclusion: The method of modified reverse left subclavian artery flap plasty has shown higher aortic arch elastic properties than in the group with extended anastomosis technique, that allows reducing an arterial hypertension rate in late post-op period.
