摘要:
FIELD: medicine.SUBSTANCE: invention refers to medicine, namely to angiology, and can be used for lifetime assessment of anatomical and physiological features of surface lymphatic vessels of lower extremities in norm and in chronic venous insufficiency. To assess the anatomical and physiological features of the surface lymphatic vessels of the lower extremities, fluorescent lymphography is used with subcutaneous injection of fluorescein into the extremity zone and exposure to the region of introduction with a light source with wavelength of 480 nm. 15 minutes after administration of fluorescein, vessels are visualized to observe yellow-green fluorescence. According to fluorescence, the medial, lateral and posterior groups of the limb vessels of the limb are isolated, the number and direction of which are used to assess the norm or chronic venous insufficiency. Prior to the procedure, fluorescein is dissolved in physiologic saline. Obtained 1 % solution is injected subcutaneously into the area of the first and second interlocked spaces, and the area of the right and left ankle is 2 ml each. Regions of introduction are documented by a digital camera at intervals. In each time interval increase in length of stained vessels is considered to calculate rate of lymphatic drain by formula: V=S/T, where S – length of colored vessel, T – time elapsed after drug administration. Localization, number, rectilinearity and diameter of lymphatic vessels, as well as direction of lymph current are evaluated. Patient's condition is evaluated proceeding from the following conditions. In the healthy individuals with 0-1 class of varicosis by CEAP for first 25 seconds after the fluorescein solution injection, the place of introduction retains the round shape elongated in the direction of injection. In next 60 seconds, the shape is elongated in the proximal direction. Preparation is delivered to the lymph capillary at 30th second. There is a projection in upper part of the spot. In 20 seco
