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.
