Doppler ultrasonography, magnetic resonance angiography, or invasive arteriography can confirm the presence of stenosis and identify the affected artery. If patients with carotid TIAs have a documented obstruction of > 70 per cent in the carotid artery, endarterectomy significantly reduces the chance of a stroke compared with medical...
