Surgical treatment of patent ductus arteriosus (PDA). Analysis of 145 cases operated on in Abidjan (Cote D'Ivoire).

This retrospective study aims to analyse our surgical procedures and our results after surgery of patent ductus arteriosus (P.D.A.) in children. Since 1978 to 1992 we have reported Abidjan Cardiology Institute 145 children operated cases. The average age was 4.7 years, the average weight 16 kg. There was female predominance with a sex ratio of 2.3/1. All patent ductus arteriosus had been confirmed by two dimensional echocardiography (2D echocardiography) and cardiac catheterization. Type 11a of NADAS' Classification was the most frequent (50%). Double or triple ligation supported on teflon felt was the most frequent technique used (86 times ie 59.3%). This technique gave good results in view of the absence of hospital mortality, only 4 cases of ductus "recanalization" supervened, a low rate of ductus arteriosus recurrence patency at long follow up of all patients from one to 10 years (mean 5 years). Double or triple ligation on teflon felt according to Wright procedure seems to be a securising technique alternative in our countries.
