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.
