[The potential for endoscopic dissection of the leg perforating veins].

This paper describes the results of endoscopic dissection of the leg perforating veins in patients suffering from different forms of chronic venous insufficiency of the lower limbs. Varicosity was present in 54 (88.4%) and postthrombophlebitis in 7 (11.6%) patients. Before operation the patients were provided ultrasound Doppler and duplex scanning. Microcirculation was examined by laser Doppler flowmetry. The study evidences decreased perfusion of the superficial skin layers during the growth of arteriolo-venular blood shunting that occurs because of phlebohypertension. For endoscopic dissection of the leg perforating veins an original titanium nickelide clips was employed, which allowed ligation of the veins measuring over 5 mm via a standard endoscopic canal. The use of the given technique made it possible to minimize the time of operation, to decrease traumatic injury of intervention due to the exclusion of incisions in the area of trophic disorders. The mean time required for ulcerous defect healing accounted for 32.3+/-1.7 days. Regulation of lower limb microcirculation was restored 3 months after surgical treatment.
