作者报告了4例椎动脉(终末端)动脉瘤的血管内栓塞治疗。术前用安定、止痛剂。术中开辟两条血管进路:①股动脉进路,目的在于做脑血管造影以便观察动脉瘤栓塞的效果和脑血流改变后脑血管的代偿情况;②腋动脉进路,插入显微球囊导管行栓塞治疗。置管方法比较复杂,先插入一个血管鞘,将一同轴导管(2F导管和-0.3～0.5mm聚四氟乙烯显微球囊导管)的球囊用碘水造影剂充胀,借助-(1)5F导管将同轴导管经血管鞘引入椎动脉
The authors report the endovascular embolization of 4 patients with vertebral artery (terminal) aneurysms. Preoperative stability, analgesics. Surgery to open up two vascular access: ① femoral artery approach, the purpose is to do cerebral angiography in order to observe the effect of aneurysm embolization and cerebral blood flow changes after compensation for cerebral blood vessels; ② axillary artery access, microspheres Cystic catheter embolization. The catheterization method is more complex. First, insert a blood vessel sheath, inflate the balloon of a coaxial catheter (2F catheter and -0.3 ~ 0.5mm Teflon microcatheter catheter) with iodine-water contrast agent, 1) 5F catheter The coaxial catheter through the vascular sheath into the vertebral artery
