Purpose : The purpose of this study is to describe the angiographic findings of collateral vessels incervicofacial vascular lesions with previously ligated carotid arteries and to evaluate the extent of angiographicassessmant needed before embolization. Materials and Methods : We retrospectively reviewed 10 cervicofacialvascular lesions with previously ligated carotid artery, which were 6 cases of arteriovenous malformation, 2 casesof carotid cavernous fistula, 1 case of hemangioma and 1 case of arteriovenous malformation with carotid cavernousfistula. The previously ligated arteries are proximal external carotid artery (n=5), branches of external carotidartery (n=2) and common carotid artery (n=3), Common carotid artery or internal carotid artery (n=9), vertebralartery (n=5), ipsilateral external carotid artery (n=4), contralateral external carotid artery (n=5), costocervical trunk (n=2), thyrocervical trunk (n=2) were assessed by conventional angiography, Angiography ofboth carotid and vertebral arteries was performed in 5 cases. Results : The collateral vascular channels wereinferolateral trunk of internal carotid artery (n=8), vertebral artery (n=5), contralateral external carotidartery (n=5), ipsilateral external carotid artery (n=4), deep cervical artery (n=2), and ascending cervical artery(n=1), Embolizations were performed in 9 cases with operative cannulation (n=4), embolization via collateralbranches of ipsilateral external carotid artery (n=1), embolization via collateral branches of contralateralexternal carotid artery (n=3) and balloon occulusion via direct puncture (n=1). Conclusion : The collateralchannels in cervicofacial vascular lesions with previouly ligated carotid artery were inferolateral trunk ofinternal carotid artery, contralateral or ipsilateral external carotid artery, vertebral artery, deep cervicalartery and ascending cervical artery on angiography. Complete angiographic assessment of possible collateralchannels is mandatory for the effective and safe embolization.
