[Surgical treatment for tetralogy of Fallot with pulmonary atresia right ventricular outflow tract reconstruction with autologous pulmonary tissue and concomitant extensive pulmonary angioplasty].
Eight consecutive patients with tetralogy of Fallot associated with pulmonary atresia successfully underwent corrective surgery without using an extracardiac conduit at a mean age of 2 years 4 months. Each of these patients had undergone a classical or modified Blalock-Taussig shunt at a mean age of 55 days. In 6 cases, central PA was fully mobilized and pulled forward. An autologous flap was made from the rudimentary PA trunk or right PA, then it was anastomosed to the endocardium of RV infundibulum as a posterior wall of the outflow tract. In 7 cases, concomitant extensive pulmonary angioplasty was performed on stenotic and under-developed lesions which were caused by tissue contraction of the PDA. During follow up period from 11 to 25 months, all patients have remained in good condition without restenosis of the RVOT. The mean pressure ratio of RV over LV measured 0.42 in 5 patients who underwent catheterization after operation. We conclude that these procedures are useful for early corrective surgery of tetralogy of Fallot with pulmonary atresia.
