Abstract

Purpose. To describe the ocular manifestations of maxi llofacial AVMs and to determine whether an arterial steal phenomenon from the ophthalmic artery is the cause. Methods. Maxillofacial AVMs of seven patients, previously treated unsuccessfully with proximal ligation of supplying arteries were evaluated. No cases had intraorbital arteriovenous (AV) shunting or abnormal venous drainage to the orbit. Results- Four of the 7 patients had signs of ocular ischemia. This was correlated with a significant ophthalmic artery steal phenomenon demonstrated by superselective angiography. In contrast, the 3 patients without ocular signs had minimal or no ophthalmic artery supply to the AV shunts. Conclusions. Ophthalmic artery steal phenomenon occurs in patients with maxillofacial AVMs that do not directly involve the orbit. It is not known if this steal phenomenon is precipitated or worsened by previous surgery.
