title: Tubular hypoplasia of the descending thoracic aorta. Surgical treatment with a PTFE bypass graft under moderate total body hypothermia.
abstract: An 8 1/2-year-old child presenting with hypertension was noted to have tubular hypoplasia of the descending thoracic aorta without collateral circulation on angiography. Surgical management consisted of bypassing the hypoplastic segment (10 cm) using a 10 mm PTFE graft under total body hypothermia to minimize spinal complications. The patient had an uneventful recovery with normalization of blood pressures postoperatively.
