Abstract

Diploic arteriovenous fistulas (AVFs) or intraosseous dural AVFs are rare arteriovenous shunts. A diploic AVF is formed between a meningeal artery and an intraosseous diploic vein or the transosseous emissary vein, and the nidus is located exclusively within the bone. Currently, endovascular embolization with a transvenous approach is considered the treatment of choice for most dural AVFs. However, in the absence of an accessible venous channel, an alternate treatment approach should be considered. Herein, we report a case of a diploic AVF that was treated using embolization with transosseous direct cannulation.

판사이 동정맥루(diploic arteriovenous fistula) 혹은 골내 동정맥루(intraosseous arteriovenous fistulas)는 동정맥 단락의 한 형태로 드물게 발생한다. 판사이 동정맥루에서 누공은 뇌막동맥(meningeal artery)과 골내 판사이 정맥(intraosseous diploic vein) 혹은 이끌정맥(emissary vein) 사이에 형성되고, 누공의 핵은 골내에만 위치한다. 현재, 경막 동정맥루에 대한 대표적 치료 방법은 혈관내 색전술로 대부분이 대퇴동맥/대퇴정맥을 통하여 접근한다. 하지만 혈관내 색전술 시 접근 가능한 통로가 없는 경우에는 대체할 수 있는 다른 접근법을 고려해야 한다. 우리는 이번 증례에서 두개골내 판사이정맥을 직접 천자하여 혈관내 색전술로 치료된 판사이 동정맥루 증례를 보고하고자 한다.
