The authors describe 4 cases of syringomyelia-associated spinal cord arteriovenous malformation (AVM). All cases were managed with embolization of the AVM. Treatments were aimed to stabilize the AVM itself and not directed toward the syrinx. In 3 of the 4 cases the syringomyelia resolved after treatment. Reports concerning AVM as a cause of syringomyelia is very scarce and lacks posttreatment clinical information. In light of the clinical course and imaging findings, the authors propose a theory that venous hypertension in the spinal cord is the trigger for the development of syringomyelia, which may reverse after AVM treatment.
作者描述了4例与脊髓空洞症相关的脊髓动静脉畸形（AVM）病例。所有病例均采用AVM栓塞治疗。治疗旨在稳定AVM本身，而非针对脊髓空洞。4例中有3例在治疗后脊髓空洞症消失。关于AVM作为脊髓空洞症病因的报道非常稀少，且缺乏治疗后的临床信息。根据临床病程和影像学表现，作者提出一种理论，即脊髓静脉高压是脊髓空洞症发生发展的触发因素，在AVM治疗后可能逆转。
