Castor分支型支架预开窗治疗异常起源左椎动脉合并Stanford B型主动脉夹层1例

Stanford type B aortic dissection with abnormal originated left vertebral artery treated by pre-fenestrated Castor branched stent-graft:a case report

56岁女性患者,突发胸背部撕裂样疼痛8 h。主动脉CTA示夹层破口位于主动脉弓大弯侧,距左锁骨下动脉约8 mm。左侧椎动脉异位起源于左锁骨下动脉和左颈总动脉间之主动脉弓。利用Castor分支型支架通过预开窗成功隔绝主动脉夹层破口,重建左锁骨下动脉和左侧椎动脉。
