Vertebral artery dissection, occurring spontaneously or following a traumatic event, is a cause of posterior circulation stroke in young individuals, including pregnant women.
A 20-year-old, primagravid woman acutely developed headache, right-sided hemiparesis and parasthesias, and blurred vision. Within days she complained of cervical neck pain. Magnetic resonance imaging findings were consistent with a posterior circulation cerebrovascular accident (CVA). An arteriogram, performed to exclude vasculitis, revealed bilateral vertebral artery dissection. No inciting event could be recalled.
Vascular dissections occur rarely during pregnancy. Spontaneous extracranial vertebral artery dissection itself is very rare in general. Cerebral ischemia can follow vertebral artery dissection. In young patients with CVA, consideration of the diagnosis of vertebral artery dissection followed-by angiography and anticoagulation is an important component of the workup and care.
椎动脉夹层，可自发出现或继发于外伤事件，是包括孕妇在内的年轻个体后循环卒中的一个病因。
一名20岁初产妇急性出现头痛、右侧偏瘫及感觉异常，以及视力模糊。数天内她主诉颈部疼痛。磁共振成像结果与后循环脑血管意外（CVA）相符。为排除血管炎而进行的血管造影显示双侧椎动脉夹层。未回忆起任何诱发事件。
血管夹层在孕期很少发生。一般来说，自发性颅外椎动脉夹层本身非常罕见。椎动脉夹层可导致脑缺血。对于患有CVA的年轻患者，考虑诊断椎动脉夹层，随后进行血管造影和抗凝治疗，是检查和护理的重要组成部分。
