[Morphological, microscopic changes in the thyroid gland in the cases of hanging in vertical position with open and closed noose].

The aim of the morphological study was to search for traumatic changes in the thyroid in the cases of hanging in a vertical position with an open and closed noose. These changes would constitute an additional proof of intravital hanging and they would be useful in postmortem diagnosis of the hangings in which other commonly acknowledged features of intravitality are not discovered. In 33% of all cases, petechiae were observed in the thyroid gland. They appeared in 20% of the hangings with the closed noose, and in 13% of the hangings with the use of the open noose. The study showed that there was no difference between the open or closed, hard noose in terms of changes in the thyroid gland. There was also no correlation between the body position and the injury of the thyroid gland. In all the cases, hyperemia of the thyroid was observed and segmental expansion of blood vessels. The histopathological analysis showed that in one third of all the cases with negative macroscopic examination, it was discovered that microscopic changes indicated hanging alive.
