Abstract Purpose There are three anastomoses between the ophthalmic artery (OA) and the middle meningeal artery (MMA): the anastomotic branch with MMA, the recurrent meningeal branch and the anterior falx artery. We aimed to evaluate the anastomotic branches between the OA and the MMA on superselective angiograms of pediatric patients with retinoblastoma. Materials and methods We evaluated 126 angiographies performed on children with retinoblastoma. The mean diameter and angiographic visibility percentage of the anastomotic branches between the OA and the MMA were examined according to age group and sex. Results The mean diameter of anastomotic branch with MMA was measured 0.58 ± 0.13 mm and we found this branch in 15 of 126 angiographic images (11.9%). We detected the recurrent meningeal branch in 47 of total images (37.3%). The recurrent meningeal branch arose 85.1% from the lacrimal artery, 8.5% from the anastomotic branch with MMA and 6.4% directly from the OA. The mean diameter of this artery was measured 0.21 ± 0.06 mm. Anterior falx artery was found in 86 of 126 angiographic peocedures (68.3%) and the mean diameter was measured 0.22 ± 0.06 mm. Conclusion Knowledge of the anastomoses between the OA and the MMA system are all necessary to perform safe and successful endovascular and surgical procedures involving the orbital region.

Introduction The main blood supplying to the orbital structures is the ophthalmic artery (OA) and its branches. The OA is a branch of the internal carotid artery (ICA) and it enters the orbit through the optic canal. The main branches of the OA are the central retinal artery, ciliary arteries, lacrimal artery (LA), muscular branches, supraorbital artery, anterior and posterior ethmoidal arteries, meningeal branch, medial palpebral arteries, supratrochlear artery and dorsal nasal artery [1]. The most crucial collateral blood supply to the orbit is the middle meningeal artery (MMA) [2]. * Hilal Akdemir Aktaş [email protected] 1

The MMA is a branch of the external carotid artery and it enters the cranium through the foramen spinosum and runs in the groove of the squamous part of the temporal bone [1, 3]. On the greater wing of the sphenoid bone, the MMA divides into anterior and posterior branches [4]. Particularly, anterior branch of the MMA contributes t
