Various surgical strategies have been reported for the treatment of aortic coarctation with hypoplastic aortic arch, including simple resection and end-to-end anastomosis as well as various forms of patch augmentation. These techniques are limited by inadequate relief of arch obstruction and use of patch material predisposed to recurrent obstruction or aneurysm formation. We report our experience with autologous aortic arch reconstruction in isolated and combined lesions, a technique that relieves even complex forms of arch reconstruction without patch material.
We retrospectively analyzed our institutional experience with autologous aortic arch reconstruction in isolated and combined cardiac lesions from November 2009 to December 2016. Study endpoints were procedural success, incidence of procedure-related complications, need for re-interventions, and survival.
In total, 54 patients underwent total autologous aortic arch reconstruction during the study period. Thereof, 13 (24%) had isolated arch obstruction and 41 (76%) had combined cardiac lesions. The majority of procedures were performed in the neonatal period (72%), median age was 8 days (range: 1 day to 4.3 years). Body weight ranged from 2.2 to 16.5 kg (median: 3.7 kg). There was one (1.9%) procedure-related early reoperation for bronchial obstruction. No repeat interventions (dilatation or re-operation) were observed. One patient with syndromic disease died on postoperative day 20 due to sepsis (1.9% in-hospital mortality rate). No late deaths were observed. Median follow-up was 23 months.
Autologous aortic arch reconstruction is a safe and effective surgical technique for the treatment of aortic arch obstruction in isolated and complex cardiac lesions. It is associated with an extremely low re-intervention rate and a low overall complication rate.
