The Intra and Extra Cranial Veins in Relationship with Chronic Migraine: Electroencephalogram Modifications Induced by Balloon Venoplasty

Objectives: Chronic Migraine (CM) is characterized by recur-rent head pain often associated with electroencephalogram (EEG) abnormalities and asymmetry of intracranial venous circulation.Migraine is a symptom of the Chronic Cerebrospinal Venous In-sufficiency (CCSVI).1.2. Methods: Seven persons with CCSVI and CM, associated or not with other symptoms, underwent Percutaneous Transluminar Angioplasty (PTA) of Internal Jugular Veins (JVSs), performed an intracranial Magnetic Resonance Imaging venography and/or Echo-Colour Doppler (ECD) of IJVs, seven an EEG before and five after PTA. A Pain Scale Assessment for CM was sampled be-fore and after PTA.1.3. Results: Seven patients show a blood flow improvement of the JVs after PTA.Before PTA, seven persons showed EEG alterations, after PTA five also showed an improvement of the EEG and all seven showed an improvement in the pain score.1.4. Conclusions: these preliminary observations suggest a strong association between CM, intra and extra cranial venous anomalies and EEG alterations
