Conus Medullaris Arteriovenous Malformation-Case Report

脊髓馬尾部動靜脈畸形-病例報告

摘要


We report a 37-year-old female patient who had progressive right foot weakness for 5 years and drop foot developed in the recent 2 years. Spinal angiographies revealed a conus medullaris arteriovenous malformation fed by the right L1 and L4 radiculopial arteries and direct arteriovenous fistulae fed by the left T12 and L1 radiculopial arteries. A large distorted right L5 great radicular vein drained along the cauda equina from the L1 to the L5 level. The distended venous varices compressing the right L5 and S1 nerve roots resulted in right foot palsy.

並列摘要


一位37歲的女性患者在過去五年有逐漸嚴重的右腳無力,近兩年更發展成為垂足症狀。脊髓血管造影顯示主要由右側L1和L4軟腦膜動脈供血的馬尾部動靜脈畸形以及左側T12和L1軟腦膜動脈供血的動靜脈瘻管;靜脈回流主要經由一條沿著馬尾從L1到L5分布、擴張彎曲的右側L5神經根靜脈。這條擴張的靜脈壓迫到了右側L5和S1神經根導致右腳麻痺。
