[Long-term evolution of a thoraco-abdominal cryopreserved arterial allograft]

Abstract

We report a case of thoraco-abdominal pseudo-coarctation which developed late after implantation of a cryopreserved arterial allograft. The allograft was placed in a thoraco-abdominal position to treat an aorto-esophageal fistula after colonic esophagoplasty. Follow-up was free of complications for eight Years. The pseudo-coarctation was discovered during the evaluation of hypertension. Surgical treatment involved transdiaphragmatic bypass between the thoracic and infra-renal abdominal aorta. Arterial pressure immediately returned to normal. Twelve Months later, the patient is alive and well with normal blood pressure. A review of the literature revealed rare cases of arterial allograft with a description of the long-term outcome.
