[Thrombosis and anatomic variants of intracranial dural venous sinuses].

A rather large number of different anatomic variants of intracranial dural venous sinuses are known, and they are found so often that interpreting them only as anomalies is unlikely, except for variations such as sinus aplasia or doubling, which can be attributed to anomalies of the venous system. Diameter reduction (hypoplasia) of the transverse and sigmoid sinuses is observed relatively often. In cases of dural sinuses anomalies, sinuses on the contralateral side are necessarily evaluated as the main source of compensation.

[Clinical presentations, diagnosis and treatment of cerebral vein and sinus thrombosis].

The problem of thrombosis of cerebral veins and venous sinuses is insufficiently studied. The real incidence of cerebral venous thrombosis remains incompletely defined. The article presents results of clinical research on cerebral vein and sinus thrombosis, which served as a ground for an analysis of causes and development of the disease.
