椎-基底动脉延长扩张症(vertebrobasilar dolichoectasia.VBD)是一种较为少见的脑血管疾病,是由于椎-基底动脉异常增粗、延长扭曲导致相邻脑干受压引起的一种临床综合征[1]。1990年Jamjoom[2]报道了VBD可引起多发神经病学损害,其原因是VBD可从椎动脉开始到基底动脉全程增粗、延长,对临近颅神经的刺激引起刺激症状,直接压迫脑干引起神经缺损症状,已报道的有引起耳鸣、前庭功能受损、面肌痉挛、三 Vertebrobasilar dolichoectasia (VBD) is a rare type of cerebrovascular disease that is a clinical syndrome caused by the abnormal thickening of the vertebrobasilar artery and the prolonged distortions that result from the compression of adjacent brainstem [ 1]. In 1990 Jamjoom [2] reported that VBD can cause multiple neurological damage, the reason is that VBD can start from the vertebral artery to the basilar artery throughout the thickening, prolonged stimulation of the adjacent cranial nerves cause irritation, direct compression of the brain stem to cause nerve Defect symptoms have been reported to cause tinnitus, impaired vestibular function, hemifacial spasm, three
