Stenting of patent ductus arteriosus in low birth weight newborns less than 2 kg- procedural safety, feasibility and results in a retrospective study

摘要

Objective: Retrospective analysis of the feasibility, safety and results of patent ductus arteriosus (PDA) stenting in low birth weight babies weighing < 2 kg. Background: Stenting of patent ductus arteriosus is a well known palliative technique for several years as an alternative to shunt surgery in babies weighing > 2.5-3 kg. Ductal stenting in babies weighing less than 2 kg is not done routinely all around the world due to limited experience and concerns regarding its feasibility and safety in such small subset. Methods: Records of patients who underwent PDA stenting at our institution from June 2014 to December 2016 were reviewed. In this period, we attempted to do PDA stenting using femoral artery approach in babies weighing < 2 kg. Echocardiography and colour Doppler were used for patient selection and assessment of procedural outcome.
