In February 2011, the American Heart Association has released an official report, which is dedicated to the diagnosis and treatment of rare and often overlooked form of stroke.
This cerebral venous thrombosis, in which are involved in the pathological process is not an artery, which most often occurs in stroke and cerebral veins.It turns out that this form of stroke is not so rare.
this stroke affects mainly children, young people, pregnant women and new mothers who have just given birth.If we talk about the development of the mechanisms of cerebral venous thrombosis, when a blood clot that occurs in the venous sinuses of the dura mater - the veins that carry blood from the brain to the heart flows away.
The most common symptom of this condition - a headache, which gradually intensified over several days or even weeks.Also recorded seizures.Some
diagnosis of cerebral thrombosis is based on clinical examination and imaging of cerebral vessels.Clinical studies show that magnetic resonance imaging is more sensitive to the detection of vascular changes in the brain than a CT scan.
addition, researchers recommend patients to carry out a survey to detect the conditions that allow the development of venous thrombosis, such as concomitant inflammatory and infectious diseases.
«In 2/3 patients with cerebral thrombosis identifies any conditions that predispose to the formation of blood clots," - says Gustavo Saposnik, one of the authors of the report, an associate professor of medicine at St. Michael's Hospital at the University of Toronto.For women, it may be pregnant, postpartum, or oral contraceptives;dehydration or infection in children.Some of these precipitating factors are transient and reversible.
Experts also argue that all patients with bleeding in the brain tissue of unknown nature necessarily requires a scan of brain veins and sinuses.
