Abstract: Objective To investigate the clinical characteristics and imaging features of limb-shaking TIA (LS-TIA).Methods The clinical data of 14 patients with internal carotid artery stenosis and LS-TIA (LS-TIA group) and 28 patients with TIA or minor disabling ischemic stroke associated with internal internal carotid artery stenosis,but without paroxysmal limb-shaking (TIA control group) were collected and compared.The clinical and imaging features of patients with LS-TIA were analyzed and summarized.Results The patients of LS-TIA group all came to the hospital for paroxysmal limb-shaking symptoms.But the attack didn't express body entasia,loss of consciousness,gatism and facial involvement.Limb-shaking usually lasted <5 min and was often involved unilateral upper limb.Common pathogenesis inducement included standing after walking,sports and cough.The incidence of hypertension in LS-TIA group was significantly higher than that in TIA control group (P<0.05).The rates of other recurrent types of transient ischemic attack in other cortical areas,amaurosis and ischemic stroke in LS-TIA group were significantly higher than those in TIA control group (all P<0.05).Patients in LS-TIA group more often had leptomeningeal collaterals than TIA control group.Conclusions LS-TIA is a rare manifestation of TIA that has been characteristic for recurrent unilateral limb-shaking of involuntary.And the pathogenetic basis of LS-TIA is internal carotid artery occlusion.Patients with LS-TIA more frequently tend to occur ischemic attacks and more depend on the collateral circulation of severe lesions on the far side of internal carotid artery stenosis.
