Percutaneous transcatheter closure of patent ductus arteriosus: Initial experience of Sohag University

Objectives: Initial experience with transcatheter closure of patent ductus arteriosus (PDA) using different types of devices is reported in Sohag University Hospital. We evaluated the outcome, complications, and also assessed the need of surgical backup for such interventional procedures. Methods: From March 2011 to September 2012, 51 patients who underwent transcatheter closure of PDA, were retrospectively identified and studied. Aortic angiogram was performed to evaluate the size, position, and shape of the duct for appropriately choosing the occluder device type and size. A second aortic angiogram was performed 10 min after device deployment. Echocardiography was repeated at intervals of 24 h, then at 1, 3, and 6 months after the procedure to assess complications. The PDA was closed by Amplatzer Duct Occluder (ADO) in 40 patients, Nit occlude PFM coil in five patients, Amplatzer muscular VSD in two patients and Detachable Cook coil in four patients. Results: Of 51 cases, one patient had left pulmonary artery embolization of ADO that required surgical intervention. The PDA was successfully closed in 98.04% of the study population without any residual PDA shunting. All the patients were alive. Infants made up 29% of the total patients. 45 patients were children and six patients were adults. Conclusion: Our initial results show that transcatheter occlusion of PDA using different types of devices is safe and effective with good midterm outcome alternative to surgery. Complications occurred in those with unfavorable duct anatomy and presence of pulmonary hypertension. Surgical backup was not important for such interventional procedures.
