[Cerebrovascular Disorders Complicating Pregnancy].

Pregnancy is a risk factor for cerebrovascular disease owing to pregnancy-related hormonal changes, a hypercoagulable state, maternal hemodynamic changes, and changes in the vascular wall. Cerebral hemorrhage and other cerebrovascular disorders account for 14% of all maternal deaths and represent the second most common cause of death after obstetric hemorrhage (38%). The timing of pregnancy-related cerebrovascular disorders. The 2008 Health and Labor Sciences Study on Pregnancy-Related Cerebrovascular Disorders (principal investigator Tomoaki Ikeda) was performed across 115 facilities between January and December 2006. The study included 184 cases of pregnancy-related cerebrovascular disorders; 39 cases of cerebral hemorrhage, 18 of subarachnoid hemorrhage, 25 of cerebral infarction, 5 of cerebral venous sinus thrombosis, and 2 cases of eclampsia and hypertensive encephalopathy. vascular disease, resulting in venous stasis, focal cerebral edema, and eventually hemorrhagic venous infarction. Ruptured cerebral aneurysms that lead to subarachnoid hemorrhage during pregnancy should be treated surgically on an emergency basis.
