Anglographic Findings of Collateral Vessels in Cervicofacial Vascular Lesions with Previously Ligated Carotid Artery
Abstract
- PURPOSE
The purpose of this study is to describe the anglographic findings of collateral vessels in
cervicofacial vascular lesions with previously ligated carotid arteries and to evaluate the extent of anglographic
assessmant needed before embolization.
MATERIALS AND METHODS
We retrospectively reviewed 10 cervicofacial vascular lesions with previously
ligated carotid artery, which were 6 cases of arteriovenous malformation, 2 cases of carotid cavernous fistula, 1
case of hemangioma and 1 case of arteriovenous realformation with carotid cavernous fistula. The previously
ligated arteries are proximal external carotid artery (n=5), branches of external carotid artery (n=2) and
common carotid artery (n=3). Common carotid artery or internal carotid artery (n=9), vertebral artery (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 of both carotid and
vertebral arteries was performed in 5 cases.
RESULTS
The collateral vascular channels were inferolateral trunk of internal carotid artery (n=8), vertebral
artery (n=5), contralateral external carotid artery (n=5), ipsilateral external carotid artery (n=4), deep cervical
artery (n=2) and ascending cervical artery (n=l). Embolizations were performed in 9 cases with operative
cannulation(n=4), embolization via collateral branches of ipsilateral external carotid artery (n=l), embolization
via collateral branches of contralateral external carotid artery (n=3) and balloon occulusion via direct puncture
(n=l).
CONCLUSION
The collateral channels in cervicofacial vascular lesions with previouly ligated carotid artery
were inferolateral trunk of internal carotid artery, contralateral or ipsilateral external carotid artery, vertebral
artery, deep cervical artery and ascending cervical artery on angiography. Complete anglographic assessment
of possible collateral channels is mandatory for the effective and safe embolization.
