Background and purpose We report the outcomes of carotid artery stenting for patients with angiographically visible occipital artery–vertebral artery anastomosis. Methods Among 47 consecutive patients who underwent carotid artery stenting from January 2007 to December 2010, seven patients for whom cerebral angiograms clearly showed occipital artery–vertebral artery anastomosis were selected. Four different protection methods were used: distal internal carotid artery protection; carotid flow reversal; seatbelt and airbag technique; and double protection method of protecting both the external and internal carotid artery. Results One patient with distal internal carotid artery protection showed a high-intensity lesion at the border of the upper thalamus, internal capsule and lateral ventricle wall after carotid artery stenting. The other patient with the double protection method did not show any high-intensity lesions on postoperative diffusion-weighted imaging in the vertebrobasilar territory. All seven patients with visible occipital artery–vertebral artery anastomosis showed ipsilateral vertebral artery severe stenosis or occlusion. Conclusion Large occipital artery–vertebral artery anastomosis may be a pathway for embolic materials during carotid artery stenting. External carotid artery protection is recommended for carotid artery stenting in such patients.

A 54-year-old man with symptomatic internal carotid artery stenosis with absence of the common carotid artery (CCA), who had been treated with surgery and postoperative radiotherapy for tonsillar carcinoma, underwent direct percutaneous carotid artery stenting (CAS). To our knowledge, this is the first report of direct percutaneous carotid artery stenting (CAS) for a patient with absent CCA.
