[Cerebral thrombotic complications, arterial and venous, disclosing inflammatory bowel disease].

A 40 year old woman presented successively an arterial and a venous cerebral thrombosis, revealing an inflammatory bowel disease. Digestive manifestations were very poor until then. Stroke is a rare complication of inflammatory bowel disease, and is usually correlated with and active phase of the disease. The mechanism by which the thrombogenic process occurs is unclear. The possible prothrombotic role of hemostasis disorders and the role of an angiitic process are discussed.
