Pseudoaneurysm formation following transarterial embolization of traumatic carotid-cavernous fistula with detachable balloon: An institutional cohort long-term study

Figure 3 Classification of traumatic carotid-cavernous fistulas according to the fistula size. A and B: Anteroposterior (AP) and lateral views of a small-sized fistula, which had good antegrade ipsilateral internal carotid artery (ICA) flow, represented by opacification of both the anterior cerebral artery (ACA) and middle cerebral artery (MCA); C and D: AP and lateral views of a medium-sized fistula, which had fair antegrade flow, represented by opacification of either the ACA or MCA; E and F: AP and lateral views of a large-sized fistula, which had poor antegrade flow, represented by opacification of neither the ACA nor MCA.
