[Hemocoagulation disorder and its impact on cerebral hemodynamics in patients with type I diabetes mellitus]

Indices were studied for the blood coagulation system in 132 patients with insulin-dependent diabetes mellitus (IDDM). The above indices tended to change toward hypercoagulation. The degree of changes was found to be related to duration and severity of illness. Patients presenting with a grave form DM more than 10 years in duration demobnstrated changes in their coagulograms suggesting the development of the chronic disseminated intravascular coagulation syndrome. Correlation has been established between fibrinogen and indices of reoencephalogram reflecting the state of the cerebral vascular system. The conclusion reached was to the effect that hyperfibrinogenemia makes for reduction in the brain pulse blood, is related to the development of venous discirculation, increase in the rigidity of cerebral vessels and heterogenuity of the blood filling in the brain.
