[Surgical correction of vascular malformations of the lower extremity].

On the basis of the Hamburg Classification from 1988 six different therapeutic tactics and surgical techniques have been proved in the treatment of vascular malformations. These are: 1) reconstructive surgery, 2) surgery to reduce the hemodynamic activity of the vascular defect, 3) surgery to extirpate the malformed vessels, 4) combined therapy, 5) unconventional therapy, 6) multidisciplinary treatment. More than 2500 cases had been worked out. In this survey the marginal vein and the embryonal vein respectively are of special interest. These veins are classified by morphologic radiologic criteria. The following types could be worked out: peripheral type, thigh type and pelvic type. Referring to these experiences the indications for vascular surgical treatment have to be distinguished precisely. In a retrospective European study the long follow-up results of all six therapeutic tactics had been registered and proved. 1378 cases were included. In 15% of the patients the results were excellent in 42% good, and in 34% an improvement could be observed. In 5% a relapse was stated and in 1.5% no change was registered.
