RESUMO
: As interventional techniques developed, more and more neurovascular diseases achieve good results by endovascular treatment. Meanwhile, cerebral angiography is also the gold standard for the diagnosis of most cerebrovascular diseases. Transient cortical blindness (TCB) is a rare complication of cerebral angiography with unclear mechanism. We report a case of dissecting aneurysm in the left vertebral artery treated by stent-assisted coiling,and patient experienced postoperative binocular complete vision loss fora short period TCB was diagnosed after relevant examinations performed. Patient's vision recovered completely after symptomatic treatment. Literatures were reviewed and the pathogenesis, imaging characteristics and treatment of TCB were summarized.
