Surgical management of patent ductus arteriosus. A review of 413 cases

Ligation under controlled hypotension is a simple, quick and effective surgical management of patent ductus arteriosus. In this study 413 cases are reviewed: clinical presentations, cardiac catheterization and operative findings are studied in relation to the surgical procedures. Ligation of the ductus was the treatment of choice in 357 cases irrespective of the age and size of the ductus with only four instances of recanalization which needed religation. Other procedures included division and suture, patch aortoplasty, transaortic patch and transpulmonary closure under profound hypothermia and arrest. There were two deaths and only five major types of morbidities described.
