Abstract

Central venous stenosis is a relatively common complication in hemodialysis patients; however, jugular venous reflux (JVR) and increased intracranial pressure are rare, and associated progressive visual disturbance was reported in only a few cases. Here, we report a case of JVR with visual disturbance and increased intracranial pressure. Notably, the MRI was accompanied by a dilatation of the superior ophthalmic vein, which was mistaken for a cavernous sinus dural arteriovenous fistula (CSdAVF). The patient had JVR on time-of-flight MR angiography (TOF-MRA) and severe stenosis of the left brachiocephalic vein on conventional angiography. After balloon angioplasty for central venous stenosis, he was discharged after improvement of his visual disturbance. Although JVR due to central venous stenosis and CSdAVF might show similar symptoms, treatment plans are different. Therefore, it is important to distinguish radiologically based on a thorough review of MRI and TOF-MRA and confirm the central venous stenosis on cerebral angiography for the accurate diagnosis.

투석 환자에서 중심정맥협착은 비교적 흔한 합병증이나, 이로 인한 경정맥역류 및 두개내압 상승은 드물며, 진행성 시력 저하를 보이는 경우는 몇 개의 증례만 보고되고 있다. 저자들은 경정맥역류로 인한 두개내압 상승, 시력 저하 그리고 뇌 MRI에서의 상안정맥 확장에 대해 해면경막 동정맥루로 오인하였던 증례를 보고하고자 한다. 환자는 time-of-flight MR angiography (이하 TOF-MRA)에서 경정맥역류 소견이 있었고, 혈관조영술에서 좌측 완두정맥의 협착이 확인되었다. 중심정맥협착에 대해 풍선혈관성형술을 시행하였고 증상이 호전되어 퇴원하였다. 중심정맥협착에 의한 경정맥역류와 해면경막 동정맥루는 유사한 증상을 보일 수 있으나 치료법이 다르므로, MRI와 TOF-MRA의 면밀한 검토를 토대로 영상의학적으로 감별하는 것이 중요하며, 뇌혈관조영술을 통해 중심정맥협착 유무를 확인하는 것이 필요하다.
