Aortic coarctation in older children most frequently represents cases of re-coarctation following previous transcatheter or surgical therapy or missed cases of native coarctation.
We describe three cases of adolescents – two girls and one boy – with aortic coarctation, operated between January, 2012 and December, 2013. Computed tomography angiography was performed as an essential diagnostic procedure.
Hypertension was detected, and weaker arterial pulses in the lower limbs were noted in all cases. All operations were performed via left posterolateral thoracotomy. Aortic coarctation was treated surgically, with left subclavian-lower descending thoracic aorta bypass grafting. Postoperative course was uneventful in all cases. No residual brachial-ankle pressure gradient was observed, and all patients have remained in good condition after the operation.
Surgical treatment of aortic coarctation in adolescent patients can be achieved by resection with end-to-end anastomosis, interposition of a graft or bypass graft across the area of coarctation when the distance to be bridged is too long for end-to-end repair.
The extra-anatomic subclavian-descending aortic bypass grafting provides good results in adolescent patients, particularly in those with complex coarctation.
