小脑延髓池穿刺造影CT扫描诊断臂丛神经根性损伤

Radiography by cerebellomedullar cistern puncture and CT scan in the diagnosis of brachial plexus roots injury

目的:介绍用脊髓造影CT扫描(computed tomographic myelography,CTM)诊断臂丛根性损伤。方法:行小脑延髓池穿刺,注入水溶性碘造影剂10ml后,在0.5～2小时内行CT检查。结果:5例臂丛根性损伤,其CTM影象与手术所见相符,1例CTM图象未见异常而手术证实为臂丛上干断裂。结论:分析了CTM诊断臂丛根性损伤的病理基础及相应影象,认为CTM是诊断臂丛根性损伤的一种敏感性高、定位准确的客观方法。

Objective: Computed tomographic myelography (CTM) was introduced to diagnose brachial plexus roots injury. Methods: 10 ml of aqueous soluble iodine was injected through cerebellomedullar cistern puncture and CT scan was followed in 0.5～2 hours. Results: In five cases with brachial plexus roots injury the CTM was consistent with the surgical diagnosis. Surgical operation revealed upper trunk of brachial plexus injury in one case but its CTM picture was normal. Conclusions: The pathological basis of brachial plexus injury by CTM examination and its relevant images were analyzed. CTM was one of the best objective methods in the diagnosis of brachial plexus injury because it was of high sensitivity and accuracy in localization.
