title: Transcatheter closure of patent ductus arteriosus.
abstract: OBJECTIVE
  To present short and intermediate results of catheter closure of patent ductus artereiosus using spring coils and Amplatzer duct occluder.
  
  
  METHODS
  Tertiary care referral hospital in New Delhi.
  
  
  METHODS
  121 patients were diagnosed to be having patency of the arterial duct between October 1996 and December 1999. Their ages ranged between 4 mo and 480 mo (mean 80.5 mo). Before August 1998 only spring coils were used as an alternative to surgical closure of the duct, whereas between August 1998 and December 1999 both coils and device were used.
  
  
  RESULTS
  Spring coils were attempted in 48, Amplatzer duct occluder in 44 and 29 patients were referred for surgery. Coils were successfully deployed in 42/48 (87.5%) and device in 42/44 (95.5%) patients. Complete closure of the arterial duct was seen in 96% patients in the coil closure group at the end of one year and 100% closure was achieved in the device closure group at the end of 3 months in all the patients followed. Coil embolised in 11 patients, significant stenosis of left pulmonary occurred in one patient and severe hemolysis requiring blood transfusion occurred in one patient after coil closure. Six patients required a second procedure to close the residual shunt within 6 months of the initial coil deployment. One patient had loss of femoral artery pulses in right leg after device closure and required heparin infusion for 48 hours. There were 8 failed attempts. All these patients have been operated successfully.
  
  
  CONCLUSIONS
  Percutaneous closure of the patent ductus arteriosus using Coils or the Amplatzer device is an acceptable method. Small residual shunts are common after the initial procedure especially after coil deployment but most close spontaneously.
