PURPOSE
To evaluate the changes occurring in spinal aneurysm (SA) size related to modification of endovascularly treated AVMs.
METHODS
Fourteen patients with an intramedullary AVM and associated SA underwent endovascular treatment of their AVM with particles. Embolization sessions numbered from one to 14 (mean five) in each patient.
RESULTS
Four patients had SAs with size changes mirroring those of the AVM with embolization: these decreased in size or disappeared after AVM reduction or cure and increased or recurred after AVM recanalization. A second group of patients had SAs that remained unchanged despite AVM changes (six of seven of these were in patients with metameric angiomatosis).
CONCLUSIONS
Results in the first group lend support to the hemodynamic theory of associated aneurysm formation. On the other hand, aneurysms that remained unchanged probably are not AVM flow-related and could be an expression of an extensive vascular disorder such as metameric angiomatosis; however, hemodynamic and developmental factors could be concurrent.
目的
评估与经血管内治疗的动静脉畸形（AVM）改变相关的脊髓动脉瘤（SA）大小的变化。
方法
14例患有髓内AVM及相关SA的患者接受了用颗粒进行的AVM血管内治疗。每位患者的栓塞疗程为1至14次（平均5次）。
结果
4例患者的SA大小变化与AVM栓塞后的变化一致：AVM缩小或治愈后SA尺寸减小或消失，AVM再通后SA增大或复发。第二组患者的SA尽管AVM发生了变化但仍保持不变（其中七分之六的患者患有节段性血管瘤病）。
结论
第一组的结果支持相关动脉瘤形成的血流动力学理论。另一方面，大小不变的动脉瘤可能与AVM血流无关，可能是广泛血管疾病如节段性血管瘤病的一种表现；然而，血流动力学和发育因素可能同时存在。
