내시경적 요추 감압술 후 큰 가성동맥류와 함께 나타난 요근 혈종에 의해 발생한 요추부 신경얼기병증: 증례 보고

Abstract

We report a case of psoas hematoma with a large pseudoaneurysm causing lumbar plexopathy following endoscopic lumbar decompression. A 34-year-old man had received posterolateral endoscopic lumbar decompression for the treatment of herniated intervertebral disc at L4/5 level. After endoscopic lumbar decompression, his low back pain, groin pain and motor weakness of his left lower extremity were more aggravated. Psoas hematoma with a pseudoaneurysm causing lumbar plexopathy was detected by computed tomography scan and confirmed by electrodiagnostic testing. In order to prevent permanent and catastrophic disability, a proper evaluation for detecting possible complication and immediate management should be needed during the early post-operative phase.
