Orbital Infarction Syndrome after Surgery for Ruptured Anterior Communicating Artery Aneurysm: Case Reports / 대한뇌혈관외과학회지

ABSTRACT

Orbital infarction syndrome is a rare complication of neurosurgical procedures. The authors recently experienced two patients suffered from acute proptosis, ophthalmoplegia, and blindness developed immediately after surgery for ruptured anterior communicating artery aneurysms. Both patients underwent standard frontotemporal craniotomies to clip their aneurysms. Retinal and choroidal nonperfusion, and ophthalmoplegia, which suggested hypoperfusion of the ophthalmic artery and its branches, consistent with the orbital infarction. We report two cases of orbital infarction syndrome and discuss possible mechanism with literature review.
