已有文献证实,常规脑血管造影中,头部旋转可引起环枢椎部位的椎动脉暂时性闭塞或机械性压迫。这种闭塞因有对侧椎动脉充分供血或椎基底动脉双侧供血而常无症状。“弓型狩猎者卒中”这一名词常指因自动或被动转头所导致的环枢椎处的椎动脉间断性受压而产生供血不足的一个综合征。 It has been documented in conventional cerebrovascular angiography, head rotation can cause temporary occlusion of vertebral artery or mechanical compression of the central axis of the vertebral axis. This occlusion due to contralateral vertebral artery full supply of blood or vertebrobasilar bilateral blood supply and often asymptomatic. The term “bow hunter stroke” usually refers to a syndrome that produces insufficient blood supply due to intermittent compression of the vertebral artery at the axis of rotation of the spine caused by automatic or passive head rotation.
