“…The ventral OphA anastomoses with the ICA near the anterior clinoid process and its proximal segment regresses too [23]. In rare circumstance, the persistent ventral OphA can be preserved, which connects the OphA and ACA [24]. In our study, type III TDC through the PEA was similar with the persistent ventral OphA.…”

Unlike its parietal, temporal, and occipital counterparts, the frontal lobe has a broad basal surface directly facing the anterior cranial fossa dura mater which could permit establishment of transdural collaterals (TDCs) with the frontal lobe. Studies on the TDCs from the anterior cranial fossa in moyamoya disease (MMD) are scarce and inadequately investigated. A retrospective study of 100 hemispheres in 50 patients who were diagnosed with MMD by catheter angiography between January 2015 and June 2019 was performed in our institution. TDCs through the anterior ethmoid artery (AEA) or posterior ethmoid artery (PEA) were divided into 3 types respectively based on their respective angioarchitecture. Furthermore, we also studied TDCs to the temporal, parietal, and occipital lobes and collaterals from the posterior circulation to the territory of the anterior cerebral artery. TDCs through the AEA and PEA were identified in 89 (89/100, 89%) and 73 (73/100, 73%) of the hemispheres. The vascularization state of the frontal lobe was good in 89 (89/100, 89%) hemispheres. Rete mirabile and TDCs through the PEA were statistically different among patients with different Suzuki stages. No statistical difference was noted in TDCs through the AEA, frontal TDCs from other sources, and the vascularization state of the frontal lobe with regard to different Suzuki stages. TDCs through the AEA and PEA at the anterior cranial fossa play a very important role in compensating the ischemic frontal lobe. The frontal lobe could be well compensated in most of the patients with TDCs at the anterior cranial fossa.

“…The aberrant stemming from the anterior cerebral artery is another rare variant of the OA origin [3, 4, 18, 20, 21, 26, 28, 37, 63]. This variation has been frequently explained with the persistence of the PVOA [3, 4, 26, 28, 37, 63], though it more probably involves a persistent recurrent POlfA (Fig.…”

An update on the variations of the orbital blood supply and hemodynamic

PurposeSeveral variations of the arterial blood supply of the orbit have been reported over the years. This review is aimed to provide an update focusing on three important issues: (a) variations of the ophthalmic artery origin; (b) contribution of the external carotid artery to the orbital blood supply; (c) orbital hemodynamic.MethodsA PubMed and Google search was carried out with the following keywords: ophthalmic artery origin, ophthalmic artery anastomoses and ophthalmic artery anatomy.ResultsThe site of origin of the ophthalmic artery displays a limited number of variations. However they are important as they are also associated with course variations. Anastomoses between the ophthalmic artery and the external carotid artery are numerous and many of them can acquire clinical relevance. Records on their anatomic frequency are limited. Orbital hemodynamic variations are a poorly studied subject. Recent investigations in children have unveiled unexpected variability and instability in the way the blood flows through the orbit.ConclusionsThe orbit shows several possible arterial variations. Some of them have a profound influence on its hemodynamic at least in children. More studies are required to ascertain if the hemodynamic variability observed in children can be pinpointed also in adults.

Objective: The ophthalmic artery and its branches have one of the most complex anatomy and embryology of all arteries. Although many studies have been done on its branches, different references have given different conclusions about the first branch of it. Therefore, it was aimed to investigate the first branch of the ophthalmic artery in this study.Materials and Method: Forty-one orbits of the cadavers, which belonged to the Department of Anatomy of Istanbul Faculty of Medicine, were examined.Results: It was observed that the first branch was the central retinal artery in 23 orbits (56%), the posterior ciliary arteries in 14 orbits (34%), the lacrimal artery in three orbits (7%) and the supraorbital artery in one orbit (3%). Conclusion:It was observed that the first branch of the ophthalmic artery was the central retinal artery or posterior ciliary arteries substantially. Both arteries are essential for vision and are very important to be protected in surgeries involving this area.
