肢体抖动型短暂性脑缺血发作的临床特点

The clinical characteristics of limb-shaking transient ischemic attack

肢体抖动型短暂性脑缺血发作（LS-TIA）可以通过发作症状来识别,主要表现为不自主的肢体抖动,一般持续数秒或数分钟,常在运动或站立后发作;可伴有局部肢体麻木,是大脑半球脑血流动力学受损的表现.在临床中容易被医生忽视,误诊为症状性癫痫.该病具有较高的卒中风险及不良预后,因此快速识别LS-TIA对于制定预防缺血性卒中的方案至关重要.LS-TIA患者可以从改善脑灌注的治疗中获益,但是血管重建术及药物保守治疗的获益程度仍有待确定,应依据患者具体的临床特点制定特异性诊疗方案.

Limb shaking transient ischemic attack （LS-TIA） can be recognized by paroxysmal cerebral hemisphere hemodynamic damage performance that lasts for several seconds or minutes, often occurring after exercise or standing and may be accompanied by numbness of the local limb. Clinically LS-TIA is ignored by doctors and misdiagnosed as epilepsy and the disease has a high risk of stroke and poor prognosis. The prompt recognition of the limb-shaking transcient ischemic attack is crucial to implement options aiming at preventing future stroke. Patients with LS-TIA can benefit from therapies aiming at improving cerebral perfusion.However, the benefit of revascularization and drug conservative treatment remains to be determined and specific diagnosis and treatment should be formulated according to the specific clinical characteristics of patients.
