Internal jugular vein valve insufficiency is not increased in migraine: an ultrasound study in migraine patients and control participants

摘要

BackgroundMigraine is a common neurological disorder of unclear pathogenesis. Recently incompetence of internal jugular vein valve (IJVVI) was found to be associated with some neurological conditions of unknown etiology such as benign cough headache, primary exertional headache or transient global amnesia. Common vascular mechanism linking transiently increased cerebral venous pressure with the above mentioned conditions was then postulated. Therefore we decided to investigate whether IJVVI may be associated with migraine.
