N-butyl cyanoacrylate proved beneficial to avoid a nontarget embolization of the ophthalmic artery in endovascular management of epistaxis. A neurointerventional report and literature review.

Epistaxis is a common disorder affecting equally both genders. Posterior origin of epistaxis in some instances requires endovascular treatment. Anastomoses between external carotid artery and internal carotid or ophthalmic arteries heighten the risk of stroke or blindness, if particles of polyvinyl alcohol are used for embolization. We report a case of 90-year-old man for whom successful embolization with N-Butyl Cyanoacrylate glue was performed as an alternative treatment for recurrent epistaxis.

Endovascular treatment of a lenticulostriate artery aneurysm with N-butyl cyanoacrylate.

BACKGROUND: Aneurysms arising from lenticulostriate artery branches in moyamoya-type disease are challenging lesions to treat, due to their fragility and deep location. Surgery is difficult and endovascular options may be limited. METHODS: A 57-year-old woman presented with a right ganglionic parenchymal hemorrhage due to a ruptured lenticulostriate artery aneurysm associated with ipsilateral middle cerebral artery occlusion. The aneurysm and parent feeding artery were occluded using endovascular injection of N-butyl cyanoacrylate. RESULTS: The aneurysm was successfully obliterated and although some glue did enter the more distal middle cerebral artery, there was no change in the patient's neurologic status. CONCLUSIONS: In highly selected cases where lenticulostriate aneurysms cannot be directly accessed for surgery or endovascular coiling, obliteration with liquid acrylic glue may be considered as a therapeutic option.
