Treatment of limb-shaking TIAs with external carotid artery stenting.

Limb-shaking transient ischemic attacks (TIAs) occur when perfusion is reduced to the cortical territory associated with the transient movements. We present a case in which a patient with preexisting left internal carotid artery (ICA) occlusion developed limb-shaking TIAs secondary to severe stenosis of her left external carotid artery (ECA). After angioplasty and stenting of her left ECA, her symptoms resolved.
