Percutaneous closure of patent ductus arteriosus in adults using different devices.

Surgical closure of patent ductus arteriosus in adults involves a number of risks because there are associated anatomic and histologic alterations. Between October 1992 and August 2008, 23 patients were referred to our department with isolated patent ductus arteriosus. Their age ranged from 16-75 years (median 25.5 years) and their weight from 52-80 kg (median 57 kg). The pulmonary diameter ranged from 1.8-5.8 mm (mean 3.5 mm), and pulmonary artery pressure, from 9-72 mmHg (mean 15 mmHg). The rate of ductal occlusion achieved with the Rashkind patent ductus arteriosus occluder was 85.7%, and it was 100% with the Amplatzer duct occluder and the Nit-Occlud coil. The average hospitalization time and follow-up duration were 24 hours and 2 years, respectively. The only immediate complication was an inguinal hematoma, and there were no late complications. In adults, closure of patent ductus arteriosus using a number of different devices, especially the latest generation devices, was safe and effective, regardless of morphologic and histologic characteristics.
