    Abstract:
    BACKGROUND: In lymphedema, tissue fluid steadily accumulates in the subcutaneous space containing loose connective tissue. We documented previously that deformation of the structure of subcutaneous collagen bundles and fat by excess fluid leads to formation of "lakes" and interconnected channels with irregular shape. Since there is no force that could mobilize and propel stagnant fluid to the regions where lymphatics absorb and contract, this task should be taken over by external massage. The most effective in this respect seems to be the sequential intermittent pneumatic compression (IPC). AIM: The aim of the study was to observe whether IPC would enhance and accelerate formation of tissue fluid channels. METHODS: Together with the Biocompression Systems (Moonachie, NJ), we designed a high pressure intermittent compression device and used in it our therapy protocol for patients with obstructive lymphedema of lower limbs. The study was carried out on 18 patients with lymphedema stages II-IV. The IPC was applied daily for 1-2 hours. The follow up time was 24-36 months. Lymphoscintigraphy and immunohistopathology of tissue biopsies were used for evaluation of channel formation process. RESULTS: The forced fluid flow brought about increase of the area of fluid channels in the thigh and groin, with a decrease in the calf. Concomitantly, with decrease of channel area in the calf, there was a decrease of calf circumference. No new lymphatic collectors were observed. CONCLUSIONS: Compression of limb lymphedema tissues leads to formation of tissue channels as pathways for evacuation of edema fluid.
