Surgical treatment of aortic arch malformations in infants under cardiopulmonary bypass

MATERIAL AND METHODS: Retrospective study enrolled 62 patients aged 55 ± 14 days who underwent aortic arch surgery under cardiopulmonary bypass. It was compared two methods of aortic archplasty: use of xenopericardial material in group 1 and Rajasinghe's autoplastic method in group 2.

RESULTS: Follow-up was 42 ± 14 months. In the long-term recoarctation occurred in 7 (13.7%) cases including 6 (18.75%) patients in group 1 and one (3.3%) patient in group 2. Residual hypertension was observed in 12 (23.5%) cases including 10 (37%) patients in group 1 and 2 (8.3%) patients in group 2. Six (50%) patients receive antihypertensive therapy, 5 (41.6%) patients who receive antihypertensive drugs have persistent increase of blood pressure without evidence of anatomic aortic obstruction. Hypertensive response to functional tests was observed in one patient.

CONCLUSIONS: Aortic arch reconstruction using autoplasty is associated with lower risk of recoarctationand residual hypertension compared with xenopericardial patch application.

AIM: To evaluate long-term results and the causes of complications in congenital obstructive pathology of the aortic arch.
