Vertebral artery dissection

A reconstruction of the vertebral arteries from a CT scan, seen from the front. From the bottom, V1 is from the subclavian artery to the foramina, V2 is from the foramina to the second vertebra, V3 is between the foramina until entry into the skull, and V4 is inside the skull embedded in the dura mater. They merge into the basilar artery, which then divides into the posterior cerebral artery.

Magnetic resonance angiogram of the neck vessels in a person with Ehlers-Danlos syndrome type IV; it shows a dissection of the left internal carotid artery, dissection of both vertebral arteries in their V1 and V2 segments and a dissection of the middle and distal third of the right subclavian artery.

Vertebral artery dissection (abbreviated VAD, often vertebral dissection) is a dissection (a flap-like tear) of the inner lining of the vertebral artery, which is located in the neck and supplies blood to the brain. After the tear, blood enters the arterial wall and forms a blood clot, thickening the artery wall and often impeding blood flow. The symptoms of vertebral artery dissection include head and neck pain and intermittent or permanent stroke symptoms such as difficulty speaking, impaired coordination and visual loss. It is usually diagnosed with a contrast-enhanced CT or MRI scan.
