Surgery for the persistent ductus arteriosus (PDA) is almost 50-years-old. It started with Robert Gross in 1938 who successfully ligated the PDA in a seven-year-old girl.! Incomplete obliteration, ligatures cutting through the ductus and recanalisation of the ductus remained troublesome possibilities with this method of dealing with the PDA. Dividing the ductus and suturing each divided end separately would eliminate these possibilities. Gross was quick to recognise this and advocated division in all cases to remove any doubt of incomplete obliteration. 2 Jones supported this concept but also stressed that division and suture of the PDA was not to be taken lightly for the fatal consequence that could arise from inexperience.f There were those who continued to have satisfactory results with ligation of the PDA and persisted with this method (Blalock." Clagett, Kirklin, Ellis and Coolev.' Panagopoulos, Tatooles, Aberdeen, Waterston and Bonham Carter"}, The debate continues between ligation on one hand, and division and suture on the other and it appears currently to favour the latter. This paper reviews our experience with surgery for the PDA over the past five years.
