초록

척수 경막외 동정맥루는 매우 드문 질환으로 진단과 치료가 어렵다. 무증상 환자도 있으나 동정맥단락으로 척수주위정맥으로 역류되고 늘어난 정맥이 인접한 신경근을 압박하면서 증상이 생길 수 있다. 본 증례는 31세 남자 환자로 2년 동안 지속되는 요통, 방사성 허벅지통증, 하지 감각변화로 내원하였다. 컴퓨터단층촬영, 자가공명장치 및 척수혈관조영술에서 요추의 경막외 공간에서 동정맥단락에 의해 늘어난 정맥이 신경근을 압박하고 있는 척수 경막외 동정맥루로 진단하였다. 코일색전술을 시행하여 동정맥단락을 차단하였고 수일 내에 신경근 압박증상이 호전되었다. 이번 증례에서는 척수 경막외 동정맥루에서 외과적 수술의 대안으로 코일 색전술이 효과적인 치료가 될 수 있다는 것을 보여주었다.

Spinal epidural arteriovenous fistulas (SEDAVFs) are rare spinal vascular malformations that are difficult to diagnose and treat. SEDAVFs can be asymptomatic; however, symptoms can arise from the compression of adjacent nerve roots by dilated vein and perimedullary venous reflux, caused by shunting into the epidural venous plexus. A 31-year-old male presented to our institution with a 2-year history of progressively worsening low-back pain, radiating thigh pain, and sensory changes in his lower extremities. MRI and CT angiography demonstrated dilated epidural vascular lesion compressing the nerve root. The SEDAVF was embolized with multiple coils, which alleviated the nerve root compression from the engorged venous varix and improved the patient's radiculopathy. Our experience from this case shows that endovascular coil embolization using the transarterial approach can be an effective treatment for SEDAVF and an alternative to surgical ligations.
