    Abstract:
    BACKGROUND: Surgical repair for hypoplastic aortic arch in neonates carries a substantial risk of recurrent obstruction. Simple arch anastomosis is not always a solution in cases of extended arch hypoplasia. We present our modified technique of extended aortic arch anastomosis augmented with subclavian flap aortoplasty. METHOD: We describe two neonates: interrupted aortic arch and transverse arch hypoplasia associated with aortic coarctation, who underwent a modification of extended aortic arch anastomosis augmented with subclavian flap aortoplasty. RESULTS: The patients recovered without any pressure gradient at the anastomotic site. Postoperative aortography showed no arch obstruction and they successfully underwent second stage repair. CONCLUSION: Our technique provides extensive augmentation of the aortic arch with a tension-free, wide and non-circumferential suture line which preserves potential for growth. The technique described may avoid persistent or repeat arch obstruction.
