【摘要】：目的探讨肢体抖动TIA(LS-TIA)的临床和影像学特点。方法采集14例有颈内动脉狭窄的LS-TIA患者(LS-TIA组)及28例有颈内动脉狭窄的无发作性肢体抖动的TIA或轻微症状的缺血性卒中患者(TIA对照组)的临床资料并进行比较。总结LS-TIA患者临床及影像学特点。结果 LS-TIA患者均以发作性肢体抖动症状来就诊,发作时无肢体强直阵挛,无意识丧失和大小便失禁症状,无面肌受累。LS-TIA患者发作持续时间通常5 min,发作的部位以单侧上肢多见,常见发病诱因包括站立后行走、运动及咳嗽。LS-TIA组患者高血压病的比例明显高于TIA对照组(P0.05)。LS-TIA组患者临床表现为其他皮质TIA表现、黑w恰⒔刮毖宰渲械谋壤飨愿哂赥IA对照组(均P0.05)。LS-TIA组患者较TIA对照组有更多的软脑膜侧支。结论 LS-TIA是一种少见表现形式的TIA,特征性表现为反复发作的单侧肢体不自主的抖动,颈内动脉狭窄是其发病基础,且更易进展为缺血性卒中,其更依赖于来自严重病变颈内动脉远端的侧支循环血流供应。
[Abstract]:Objective to investigate the clinical and imaging features of limb jitter TIA-LS-TIA. Methods 14 patients with internal carotid artery stenosis (LS-TIA) and 28 patients with internal carotid artery stenosis (TIA) without paroxysmal limb jitter or ischemic stroke with mild symptoms were collected. The clinical data of patients with LS-TIA were compared. The clinical and imaging features of patients with LS-TIA were summarized. Results all patients with LS-TIA were treated with paroxysmal limb jitter. There were no limb tonic-clonic, unconscious loss and incontinence, no facial muscle involvement. The duration of attack was usually 5 minutes. The site of attack was more common in unilateral upper limb, and the common inducement included walking after standing. The proportion of hypertension in exercise and cough. LS-TIA group was significantly higher than that in TIA control group (P 0.05). LS-TIA group showed other cortical TIA manifestations. Scratch? Avoid? Kill your arms and seek earth? ? There were more lateral branches of pial meninges in the control group (P0.05U. LS-TIA) than in the TIA control group. Conclusion LS-TIA is a rare manifestation of TIA, characterized by recurrent involuntary wobble of one side of limb. The stenosis of internal carotid artery is the basis of its pathogenesis, and it is more likely to develop into ischemic stroke, and it is more dependent on the blood supply of collateral circulation from the distal end of the internal carotid artery.
