Management of Dissecting Aneurysm of Cervicocephalic Carotid and Vertebral Artery / 대한뇌혈관학회지

The pathogenesis of spontaneous cervicocephalic arterial dissection is still incompletely understood. The clinical presentation of the arterial dissection depends on the plane where the dissection occurred in the arterial wall. When the outer media or subadventitia is dissected, the intramural hematoma bulges outward to make dissecting aneurysm. When located in the subintima or inner media, the intramural hematoma produces narrowing or occlusion of the vessel lumen. Authors review etiopathogeness, clinical features, diagnosis and management of cerviococephalic arterial dissection.
