METHOD FOR ENDOVASCULAR LASER COAGULATION OF VARICOSE GREAT SAPHENOUS VEIN Russian patent published in 2015 - IPC A61B17/00 A61N5/67 

FIELD: medicine.

SUBSTANCE: first stage involves the antegrade palpation-assisted insertion of a heavy-ended phlebextractor through an incision at the medial malleolus to straighten varicose segments. The phlebextractor is removed thereafter from the incision at the medial malleolus. Tumescence anaesthesia is applied along the vein trunk. That is followed by the coagulation of an inconsistent tibial segment of the great saphenous vein with the use of a laser light guide. The laser light guide is removed from the incision at the medial malleolus. A cosmetic stitch is applied on the wound. At the second stage: the heavy-ended phlebextractor is inserted palpation-assisted in the retrograde direction through a cross-ectomy incision to straighten varicose segments. The heavy-ended phlebextractor is used to remove any inconsistent valves, and an aiming beam controlled laser light guide is delivered along the phlebextractor. Thereafter, the phlebextractor is taken out of the cross-ectomy incision. Tumescence anaesthesia is applied. That is followed by the laser coagulation of an inconsistent femoral segment of the vein. The laser light guide is taken out of the cross-ectomy incision. The great saphenous vein stump is ligatured. The wound is closed. The whole surgical procedure is continuously ultrasound-controlled.

EFFECT: method enables the laser light guide coagulation of the inconsistent segments of the vein causing no paravasal inflammatory reaction, delivering the laser light guide precisely by using the heavy-ended phlebextractor.
