[Repeated surgical treatment of varicosity: the causes and specific features].

The paper is concerned with repeated surgical treatment for varicosity. The studies were carried out of the efficacy of surgical treatment at the specialized angio-surgical and general surgery hospitals. It has been discovered that after treatment at the specialized hospitals the patients applied for repeated surgical assistance 6 times less frequently. It is shown that the incompetent perforating veins provoke the recurrence of the symptoms of varicosity. An original technique for their obliteration is offered using highly intensive laser radiation (HILR) under permanent ultrasound guidance. The optimal parameters of HILR for venous obliteration were worked out in animal experiments. The experimental data were confirmed by microscopy and electron scanning microscopy. The clinical observations have demonstrated the high efficacy and safety of the treatment method offered.
