![]() ![]() Various extra-anatomic techniques to bypass the lesion and at the same time decrease the potential complications of traditional anatomic repair have been described. Anatomic bypass is therefore associated with a high risk of postoperative morbidity and mortality. Conventional repair of aortic interruption by end-to-end anastomosis, as done for coarctation of the aorta, is often a surgical challenge in view of the extensive collateral vessels that develop on the chest wall and inside the chest cavity. It is often diagnosed and repaired during the neonatal period. Interruption of the aortic arch in the adult population is an extremely rare entity. Ventral aortic repair through a midline approach is our preferred technique for surgical repair of this entity, because it avoids the extensive network of collateral vessels on the chest wall, enables simultaneous treatment of associated lesions, and in all likelihood reduces morbidity and mortality. Interruption of the aorta is rare in adults. Graft patency in all the patients was confirmed by computed tomographic angiography. All patients were asymptomatic however, 5 patients had mild residual hypertension. There was no in-hospital or late mortality or need for re-intervention. No neurologic, renal, or gastrointestinal complications were noted in any patient. The mean follow-up was 17.28 ± 7.1 months (range, 9–31 months). All repairs were performed without cardiopulmonary bypass.įollow-up was complete in all patients. A bovine collagen-impregnated polyester fiber graft was used in 6 patients, and a Gore-Tex® graft was interposed in 1 patient. Five patients underwent ventral aortic repair through a mid-sternotomy and an upper midline laparotomy, and 2 patients underwent repair through a left posterolateral thoracotomy. Clinical profiles, surgical management, and results of early and mid-term follow-up are presented.įrom August 2001 through June 2003, 7 adult patients underwent an extra-anatomic bypass procedure to repair interruption of the aortic arch. We reviewed our 3-year experience in treating interruption of the aorta in adult patients. ![]()
