PMAVFs are rare entities that are formed by a direct communication between an artery that feeds the spinal cord and a vein. The goal of treatment is to occlude the shunt; this is done endovascularly either from an arterial or a venous approach. When these approaches are not possible, direct percutaneous puncture of the draining veins may be attempted to embolize the arteriovenous shunt directly.
脊髓动静脉瘘(PMAVFs)是一种罕见的病变,由供应脊髓的动脉和静脉之间的直接沟通而形成。治疗的目标是闭塞分流;这可以通过动脉或静脉途径进行血管内治疗。当这些方法不可行时,也可以尝试直接经皮穿刺引流静脉,以直接栓塞动静脉分流。
