  • Title: Polytetrafluoroethylene shunts in congenital heart disease.
    Author: Nanton MA, Roy DL, Murphy DM, Finley JP, Lau H, Gillis DA, Murphy DA.
    Journal: Can J Surg; 1982 Mar; 25(2):134-8. PubMed ID: 7066772.
    Abstract:
    Over a 2-year period the authors inserted 22 systemic to pulmonary artery shunts using a polytetrafluoroethylene (PTFE) graft in 19 children. A modified Blalock-Taussig shunt was established in 18 instances and an aorta to pulmonary artery shunt in 3: one patient had an aorta to right ventricle infundibulum shunt. Three children had obstructed grafts and in two others the grafts became stenosed; on of the latter group had successful removal of thrombus. The remaining grafts functioned well. Three other patients are presented. In two an interrupted aortic arch was repaired using a PTFE graft; one of these patients died at later closure of an aortopulmonary window, the other did well following repair of a ventricular septal defect and aortic valvotomy. The third child had a right ventricle to pulmonary artery shunt established for tetralogy of Fallot with pulmonary atresia; this resulted in some growth of the pulmonary arteries. The modified Blalock-Taussig shunt, using a PTFE graft, can be inserted without opening the pericardium, normal flow through the subclavian artery is not interrupted, the PTFE is easy to handle and the shunt can be inserted and taken down more easily than traditional shunts. For these reasons, the authors believe that this procedure, using PTFE, has an important role to play in the surgical management of children with congenital heart disease.
