Endovascular management of ruptured choroidal aneurysms associated with moyamoya syndrome: A two-patient case report & review of the literature.

Ruptured choroidal microaneurysms associated with moyamoya syndrome are rare entities. Their small size and deep/distal location make them challenging to treat. Both surgical and endovascular treatment options carry significant risk of stroke. Here we present a two-patient case report of ruptured choroidal microaneurysms treated with Nbutyl cyanoacrylate (nBCA) endovascular embolization utilizing neuromonitoring and provocative testing during one of the cases. We also present a review of the literature evaluating surgical and endovascular treatment of these aneurysms.
