頸髄損傷のCT-myelography

CT-Myelography of Cervical Cord Injury

I．はじめに

　近年，脊推・脊髄外傷に対して水溶性造影剤によるCT-myelography（以下CTMと略す）が行われるようになり，脊椎管内へ突出した骨折片や椎間板突出による脊髄の圧排像が横断面から描出され，脊髄自体の形態，特に腫大像も容易に診断可能となってきた．

　今回われわれは，急性期頸髄損傷のCTM所見について，特に脊髄腫大と神経症状および予後との関連を検討したので報告する．

We reported seven cases of acute cervical cord injuries who were examined by CT-Myelography (CTM) within 7 days after trauma. The presence or absence of spinal cord enlargement, the initial neurological status and the neurological prognosis of these patients were studied. The neurological status of each patient was graded by the method of Frankel who defined five grades from A to E according to the severity of neurological deficits. Seven patients were all males. The youngest was 18 and the oldest was 73 years old, with a mean age of 40.7 years. Follows up periods ranged from 7 to 23 months.
