ABSTRACT
<p><b>OBJECTIVE</b>To investigate the dangerous anastomasis between the external carotid artery and the intracranial arteries.</p><p><b>METHODS</b>Angiograms of the external carotid artery in 250 cases were analyzed, including 35 cases of moyamoya and 215 cases of head and neck lesions.</p><p><b>RESULTS</b>The 35 cases of moyamoya, 14 middle meningeal arteries (MMA) were found to participate in the blood supply of the brain. In addition, 11 superficial temporal arteries and 7 occipital arteries supplied the brain. All the cases with ligated external carotid artery (ECA) had the pharyngo-occipital anastomasis. Moreover, the ophthalmic arteries in three cases were found to originate from the MMA.</p><p><b>CONCLUSIONS</b>The external carotid artery has a variety of anastomasis with the internal carotid artery (ICA) and the vertebral artery. Under such circumstances, special measures must be taken to circumvent inadvertent intracranial embolization.</p>
