Limb-Shaking Transient Ischemic Attacks: Diagnosis, Prognosis, and Management

Abstract

Limb-shaking transient ischemic attacks (LSTIAs) are a rare manifestation of carotid occlusive disease. We report the case of an 81 year old woman who presented with recurrent LSTIAs and received conservative treatment with cessation of her antihypertensive medications. Multi-Slice Detector CT Angiography (MSCTA) demonstrated a right internal carotid artery occlusion with evidence of cerebral autoregulatory compensation via leptomeningeal vessels. This case characterizes LSTIAs and demonstrates the use of MSCTA in diagnosis, prognosis, and management.
