[II-JCKO5-02] Stent of PDA as an alternative to Blalock -Taussig Shunt: single center experience
BACKGROUND: assess the characteristics, indications,technique, safety, efficacy, short-term outcome, and complications of patent ductus arteriosus (PDA) stenting in duct-dependent congenital heart diseases as an alternative to surgical shunt.
METHODS: Between May 2012 and Aril 2013, 24 patients with duct-dependent congenital heart diseases underwent PDA stenting as first palliative procedure.
RESULTS: Characteristics: mean age (days) is 56.8+ 76.4 (2 to 225). Mean weight (Kg) is 3.6+1.3 (2.1 to 7.7). Indications: pulmonary atresia with intact ventricular septum (5; 20.8%), pulmonary atresia with ventricular septum defect (13; 54.2%), pulmonary stenosis (4, 16.7%), D-TGA (1;4.2%) and Tetralogy of Fallot (1; 4.2%). Technique: in 20 patients (83.3%) stents were implanted by retrograde arterial approach and 4 patients (26.7%) by antegrade femoral venous approach. In 14 patients (54.2%) stent were implanted with coronary stent, 10 patients with renal stent. Results: PDA stenting was successful in 18 patients (91.6%) and failed in 2 patients (8.4%). Saturation increased from 59.3 (45-75) (before stenting) to 87.2 (56-99) (after stenting). For those with successful procedure, 15 patients (62.5%) with wide patent stent, 6 patients (25%) died due to decreased saturation. Short-term complications:three patients (12.6%) stent dislodged and migrated. There was no procedure-related mortality.
CONCLUSION: PDA stenting is an attractive alternative to surgical shunt in a majority of patients with duct-dependent circulation on account of post operative morbidity and complications of surgical shunt.
