title: Patent ductus arteriosus: transcatheter closure with a transvenous technique.
abstract: Transvenous closure is described of the patent ductus arteriosus with a conical device that consists of polyurethane foam mounted on a stainless steel frame. Since 1981, the procedure has been performed in 273 patients in Russia. Permanent complete ductus closure was achieved in 258 (95%) patients. In eight cases (3%), the occlusion was incomplete. Complications occurred in 10 patients (4%), seven of whom required emergency surgery. The new technique combines certain advantages of both alternative methods. The conical shape of the occlusion device is well suited for the anatomic structure of the ductus. The possibility of selecting the size of the device permits reduction in the rate of incomplete closure while still taking advantage of transvenous delivery to avoid entry-site problems. In the initial 10 years of experience, the described technique proved effective, safe, and applicable in the vast majority of patients older than 2 years.
