Der Verschluß des Ductus arteriosus persistens ohne Thorakotomie***

The reported frequency of residual leaks after surgical ligation of patent ductus arteriosus (PDA) varies from 6% to 23%. Reports on percutaneous closure of PDA also involve patients with residual PDA after ligation, but specific data regarding this type of PDA are rare. Our objective was to assess retrospectively the characteristics of residual PDA relevant to transcatheter closure and occlusion results using three types of occluders. Twelve consecutive patients underwent transcatheter occlusion of residual PDA after surgical ligation at a median age of 4.6 years (range 3. 2-44.6 years) and median weight 16.5 kg (range 13-62 kg). Three types of occluder were used: Gianturco coils, detachable Cook PDA coils, and the new Amplatzer duct occluder. The median diameter of residual PDA after ligation was 1.5 mm (range 0.9-4.2 mm). All PDAs were of type A morphology. Thirteen devices were successfully placed in the 12 patients, without embolization. There were no complications. At 1 month and 1 year follow-up all residual shunts were completely closed. Coils are particularly suitable for complete closure of residual leaks after surgical ligation of PDA. A 100% closure rate was achieved with a low number of implanted coils.

“…Coil occlusions were performed transarterially and heparin was administered to all patients after placement of the arterial sheath. In the patient with the narrowest PDA (patient 7) the rail technique was used to cross PDA with a 4.0 Fr delivery catheter [3,9,10].…”

“…In 1967, Porstmann et al described the use of Ivalon plugs to close PDAs through very large sheaths [31]. In 1979, Rashkind and Cuaso [33] reported successful use of a small, hooked, single umbrella device to close a PDA in an infant.…”

Transcatheter embolization of superfluous vascular structures has assumed an important role in pediatric interventional cardiology. A variety of devices and materials are being used to treat an increasing number of unwanted arterial, venous, and surgically created vascular connections. In general, the occlusion techniques are simple, the results are good, and the complication rates are low. The current indications, devices, materials, methods, applications, and results of pediatric cardiovascular embolization therapy are described.

“…There was a wide gap in time between the first reported successful ductal ligation by Gross and Hubbard in 1939 [9] and the first reported transcatheter ductal occlusion device by Porstmann in 1967 [17]. Reports of other devices soon followed, most notably the Rashkind PDA occluder [19] and the Sideris ''buttoned'' device [18].…”
