Carotid artery dissection caused by an amusement activity called Typhoon [Tayfun adli{dotless} eǧlence aktivitesinin sebep olduǧu karotis arter disseksiyonu]

Carotid artery dissection(cad) and cardiac embolism are the frequent causes of stroke in young and middle aged adults. it has an incidence of 2.6-2.9/100.000 per year. the pathogenesis of dissections is unknown. cad is thought to arise from an intimal tear that makes a penetration of circulating blood into the vessel wall,than this hematoma causes longitudinal and/or circular extension. it may develop spontaneously or after trauma. in %85 of cases,central neurological signs such as stroke,transient ischemic attack and amarozis fugax are seen,while headache and cranial nerve paralysis can be the presenting symptom in the rest of the cases. we reported a patient with cad 30 minutes after a typhoon(an amusement activity) ride.
