ASPEE A, Camila et al. Surgical management of Persistent Ductus Arteriosus in the Xllth region of Chile. Rev Chil Cardiol [online]. 2009, vol.28, n.4, pp.369-374. ISSN 0718-8560.

Patent ductus arteriosus (PDA) accounts is a very important problem for extreme premature newborns < 1500 g due to a high associated morbi-mortality in this group of patients. After the arrival of a pediatric cardiac surgeon and training in appropriate echocardiography diagnosis, surgical treatment of this condition began at the Regional Hospital in Punta Arenas, Chile. Aim. to repon local results of PDA surgical treatment in neonates and children during a 9 year period. Method. All patients operated on for closure of PDA from September 1997 to August 2006 were included. A retrospective recollection of data, age weight at time of surgery (preterm neonates), means used to diagnose PDA, co-morbidity, surgical technique, complications and survival, was performed. A sepárate analysis of preterm neonates (PTN) and pediatric age patients (PA) was carried out. Results. 16 PTN and 10 PA patients were operated on. Overall, age at operation ranged from 9 days to 6 years. Weight of PTN ranged from 572 to 2062 g. Diagnosis was confirmed by echocardiography in all but one patient. Echocardiographic findings were discussed via tele-medicine with experienced specialists in many cases. The local surgical team was supported by an experienced surgeon in 20 % of PTN and 60% of PA patients. A transpleural approach was used in 4 and an extrapleural approach in 22 patients; no pleural drainage was used. There were no significant complications. Only 1 patients has died in follow-up ranging from 2 months to 9 years. Conclusions. Local resolution of PDA in neonates and small children has been made possible in Punta Arenas, avoiding dangerous transfer of these patients. Assistance by trained specialists was essential to accomplish this goal. Use of tele-medicine proved to be an important factor to increase safety in the management of PDA.
