Abstract

The aim of the study was to determine the clinical significance of radioisotope and contrast lymphography when choosing the type of surgical intervention or correction of conservative treatment.

Radioisotopic lymphography (112 patients) was performed using a radiopharmaceutical (TSC-17, labeled Tc99), which was injected intradermally into the region of the first interdigital gap of the foot. Contrast lymphography (58 patients) was performed after catheterization of the lymphatic vessel on the back of the foot or in the lower third of the shin using an operating microscope. Immediately, the lymphography was performed using water-soluble contrast in 51 patients and only in 7 patients with fat-soluble majodil in the conditions of an angiographic study with computer and vidioscopic recording of the results. This allowed us to investigate not only the static, anatomical, structural structure of the lymphatic system of the part of the body being examined, but also visually determine their functional parameters.

When analyzing the results of lymphography, it was found that there is a direct correlation between them. Direct contrast lymphography mainly reflects the structure and structure of the lymph system, clearly defines traumatic, congenital and iatrogenic pathological conditions. Radioisotope lymphography characterizes functional and dynamic parameters in a digital mode. The latter, due to its low invasiveness and the possibility of repeated use, has significant advantages over direct lymphography.

The results of radioisotope lymphography were confirmed by contrast lymphography data with iatrogenic damage to lymphatic collectors, nalia lymphocele, distal hypoplasia, and proximal block of congenital or acquired genesis. Digital indicators of resorption, accumulation in regional lymph nodes and the distribution of RFP in tissues allows for a clinical analysis in each specific case.

Thus, due to the least traumatism and the possibility of repeated conducting a radioisotope type of research is preferable in conservative treatment, when dynamic control is necessary.
