PURPOSE: Embolization of middle meningeal artery (MMA) has been proposed for postoperative recurrences and primary treatment of chronic subdural hematoma (CSDH). This endovascular intervention is safe only when MMA originates from the internal maxillary artery. The aim of this study was to report an unusual high frequency of MMA originating from the ophthalmic artery, which prohibits this treatment.
METHODS: In this retrospective study, we reviewed the anatomical origin of the MMA in patients with CSDH who were referred to our center for endovascular treatment between January 2017 and May 2019 (42 patients with 58 CSDH). We compared the prevalence of this variant in a control group of 66 patients who underwent embolization for epistaxis during the same period.
RESULTS: In CSDH group, MMA originated from the ophthalmic artery in 8 out of 58 internal carotid arteries (13.8%). In the control group, this variant was observed in only 1 case out of 131 internal carotid arteries (0.7%) (OR = 20; 95% CI 2.6 to 925.2, p = 0.0003).
CONCLUSION: In this study, we report an extremely high prevalence of MMA originating from the ophthalmic artery in CSDH. In the hypothesis of prospective studies, a priori recognition of this variant will be necessary in order to exclude patients in whom endovascular treatment will not be feasible.
