[A methodologic variant in transarterial closure of a persistent ductus arteriosus].

The most severe complications in transarterial closure of the ductus arteriosus persistens are problems with placing the plug into the ductus (misfit plug size/ductus size) and the flow of closure materials into the aorta after instable fixation of the plug. In such cases surgical intervention by arteriotomy or aortotomy for the removal of the plug becomes necessary. Transvenous dilatation of the ductus arteriosus persistens after recognizing unstable plus positions or difficulties in fixing the plug prevents the mentioned complications.

Transluminal closure of patent ductus arteriosus: long-term results of 208 cases treated without thoracotomy.

Patent ductus arteriosus was the first inborn cardiac defect ever eliminated by percutaneous transvascular therapy. The method, results, and complications of Ivalon plugging of the ductus in 208 patients between 5 and 62 years old and treated between 1967 and 1985 are described. Permanent closure was accomplished in 197 patients (94.7%). The following particular benefits are obtainable from the method: no need for thoracotomy; local anesthesia applicable to 65% of all cases; 30 mm average time of intervention; only moderate invasiveness to the patients; only 7 days of hospitalization; good cost-benefit ratio.

[Transluminal angioplasty in combination with surgical procedures in arteriosclerotic occlusive disease of the lower extremity (author's transl)].

In 16 patients suffering from occlusions of the pelvic and/or femoral arteries a combined treatment was performed: percutaneous transluminal angioplasty (PTA) and surgical reconstructive measures. Indications for this procedure are: 1. Stenoses of the pelvic arteries and occlusion of the ipsilateral superficial femoral artery with PTA for the iliac artery and endarterectomy for the femoral artery. 2. Occlusion of the iliac and the femoral arteries with a decreased run-off: PTA and lumbar sympathectomy. 3. Endarterectomy on one side and PTA contralaterally.
