The literature data which demonstrate the possibilities of using computed tomography (CT) with contrast agents for the analysis of the deceased patients' bodies are presented. It is shown that postmortem CT angiography significantly expands the possibility of so-called noninvasive autopsy. The information on the features of the use of different types of con-trast agents as well as the main methods of postmortem CT angiography are presented. The use of targeted postmortem CT angiography allows to study the features of blood supply and to identify pathological changes in blood vessels of certain organs, in particular, coronary heart disease and cerebrovascular lesions. CT angiography of the whole body, especially multiphase postmortem CT angiography, allows to visualization of the cardiovascular system as a whole. The use of CT angiography is most effective for determining the source and volume of internal bleeding, the severity of thrombosis and the degree of stenosis of blood vessels, the type and prevalence of vascular malformations. We noted the complexity of the application and possible artifacts of postmortem CT angiography. It was concluded that postmortem CT angiography can be used to analyze of the bodies and clarify the tanatogenesis of deceased patients. We accented that postmortem CT angiography cannot fully replace the traditional autopsy despite its high specificity and sensitivity with regard to visualization of fatal bleeding.

The paper describes the procedure to prepare endothelial cell monolayer samples from the vascular intima, which is suitable for studying various morphological processes. To obtain high-quality multicellular specimens, it is recommended to preliminarily remove excess tissue from the outside of the vessel and to free the intima; ways to dry the surface and to separate endothelial cells are examined. The paper gives the figures of specimens stained by the Romanowsky-Giemsa method and identifies factor VIII, an endothelial marker, and Chlamydia pneumoniae inclusions in the cytoplasm of endothelial cells.

This article presents an overview of the literature publications concerning pathological changes in the cerebral blood vessels and the factors underlying the development of hemorrhagic complications leading to sudden death of young people. The special emphasis is placed on the most important causes behind the changes in the vascular wall (including the congenital ones) responsible for the high risk of rupture of the intracerebral vessels associated with the development of hemorrhagic complications.
