We report a case of visual deterioration after Onyx HD 500 embolization of a left
7 mm superior hypophyseal artery (SHA) aneurysm. After the procedure, the patient
experienced a right incongruous homonymous hemianopia, and MRI showed an infarct
of the ipsilateral optic chiasm/tract but no evidence of aneurysm mass effect or
embolic cortical infarcts. The optic pathway ischemia is believed to be secondary
to Onyx penetration and occlusion of an SHA branch near the aneurysm neck.
Caution is advised when using liquid embolic agents to treat SHA aneurysms as SHA
occlusion may lead to visual deficits.
