text: Vertebral artery dissection most commonly occurs at C1-2, due to compression of the vessel against the C2 cervical foramina during head rotation, and at C5-6, where the artery enters the transverse foramina.4 Compression of the vessel can cause blood to pool and clot in the vessel, then subsequently embolize to distal vessels, resulting in ischemic stroke.
