Carotid artery stenting in a patient with internal carotid artery stenosis and ipsilateral persistent primitive hypoglossal artery presenting with transient ischemia of the vertebrobasilar system: case report



Carotid artery stenting in a patient with internal carotid artery stenosis and ipsilateral persistent primitive hypoglossal artery presenting with transient ischemia of the vertebrobasilar system: case report



Neurologia Medico-Chirurgica 50(10): 921-924



A 62-year-old man experienced transient episodes of vertigo associated with left upper extremity weakness. Cerebral angiography showed 75% right internal carotid artery (ICA) stenosis and divergence of a persistent primitive hypoglossal artery (PPHA) distal to the stenosis. The area of stenosis was at a high position and he had a past medical history of congestive heart failure, which contraindicated carotid endarterectomy (CEA). Therefore, carotid artery stenting (CAS) was performed with single distal balloon protection. The stenotic area was restored and he was discharged without suffering recurrent attacks. CAS may be an effective alternative treatment to CEA to prevent further ischemic attacks in the posterior circulation in patients with PPHA. CAS using simple embolic protection devices is possible if the distance between the distal end of the ICA stenosis and the origin of the PPHA is sufficiently long.
