Retinal arterial macroaneurysms [PDF]

Acta Ophthalmologica, 2013
Abstract.Retinal arterial macroaneurysms are acquired saccular or fusiform dilatations of the large arterioles of the retina, usually within the first three orders of bifurcation. They are associated with systemic vascular conditions such as hypertension and arteriosclerotic disease occurring most commonly in elderly women. The primary reported symptom

Cilioretinal Artery Occlusion after Endovascular Coil Embolization for Anterior Communicating Artery

Brain Sciences, 2021
Unruptured intracranial aneurysms have a risk of rupture, so coil embolization is widely practiced as it preserves a patent artery. There are complications of coil procedures, such as patent artery occlusion and thromboembolism, which can result in ...
