PATHOMORPHOLOGIC CHARACTERISTICS OF THYROID GLAND VASCULAR SYSTEM AT THE DIFFUSE TOXIC GOITER
Abstract
Aim. To study the morphologic change of thyroid gland vessels at the diffuse toxic goiter.
Material and methods. The autopsy material of thyroid gland tissue with an intra-organic blood channel received from 22 operated patients with a diffuse toxic goiter that persisted for 5 - 7 years was an object of the research. Material preparation and the subsequent preparation of paraffinic sections were carried out by standard methods. The morphometric research included measurements of the sizes of intra-organic vessels of the thyroid gland (arterioles and capillaries) with subsequent calculation of the average indicators.
Results. Morphologic study of thyroid gland vascular wall revealed the appreciable prevalence of dystrophic changes and thickening of vessel walls in a stroma of the thyroid gland. The structure of a vascular wall was defected due to dystrophic and necrobiotic processes. That brings to hyperpermeability that results in stagnation of a blood and causes edema in the stroma of the organ.
Conclusion. The change of intra-organic vascular system structure of the thyroid gland at the diffuse toxic goiter leads to various types of circulation breaches and depends on duration and severity of the disease.
