概述

腕管综合征又称正中神经挤压综合征、腕管狭窄性腱鞘炎、腕部正中神经损伤综合征。正中神经在腕管内受压所致的手指麻木、刺痛,或鱼际麻痹称为腕管综合征。该综合征临床上并非少见,而往往在诊断上容易被忽略。如能明确诊断,针对病因进行手术松解术等治疗,效果良好。病因与病理Hass等1969年报道本综合征可出现于妊娠或绝经期,因此推测与内分泌有关,著者认为家族性的腕管综合征与一般腕管综合征有实质的不同。腕管局部外伤、劳损、骨折、脱位、韧带增厚均可引起腕管狭窄以及深浅屈指肌腱炎症等,以致腕管内的正中神经受压而

We found a reduction in FA of the median but not ulnar nerve in patients with CTS. In addition, median RD increased but AD did not change. The pattern identified here is similar to recent DTI studies at lower field strength in patients with CTS24,36,37 or other peripheral neuropathies.31,38,39 Reduced FA and increased RD are also the predominant findings in experimental nerve injury models, where they correlate with histological markers of axon and myelin degeneration,40–42 or the presence of inflammation-induced edema.43 In humans, correlation of diffusion parameters with electrodiagnostic parameters thought to reflect axonal damage or demyelination reveal conflicting outcomes.24,44,45 This may be attributed to the limited ability of electrodiagnostic tests to differentiate axonal from myelin damage46,47 as well as their inability to determine changes in small fibres (C and Aδ), which are affected early in CTS.10 Importantly, intraneural edema,which is likely present in entrapment neuropathies such as CTS48 and can influence DTI parameters,43 cannot be depicted with electrodiagnostic tests.

我们发现CTS患者的中位数FA减少但不是尺神经。此外,中位RD增加但AD没有变化。这里确定的模式类似于最近在CTS24,36,37或其他外周神经病变患者中较低场强的DTI研究.31,38,39减少FA和增加RD也是实验性神经损伤模型中的主要发现,其中与轴突和髓鞘变性,40-42或炎症引起的水肿的组织学标志物相关.43在人类中,扩散参数与被认为反映轴突损伤或脱髓鞘的电诊断参数的相关性揭示了相互矛盾的结果.24,44,45可能是由于电诊断试验能够有效区分轴索和髓鞘损伤[46,47]以及它们无法确定CTS早期受影响的小纤维(C和Aδ)的变化。重要的是,神经内水肿,可能存在于诱捕神经病如CTS48并且可能影响DTI参数,43不能用电诊断测试来描述。
