Abstract
We report an uncommon case of posterior circulation stroke in a young patient due to occlusion of posterior cerebral artery with reducible atlantoaxial dislocation (AAD). Plain dynamic radiography showed reducible AAD and intra-arterial digital subtraction angiography demonstrated occlusion of left posterior cerebral artery. Patient underwent stabilization of craniovertebral junction by occipito cervical fixation using occipit-C2/C3 lateral mass screws and rod fixation and has since experienced no recurrent symptoms. Vertebrobasilar insufficiency is a known entity in a patient with reducible AAD; however, isolated involvement of posterior cerebral artery is very rare. So this condition should be kept in mind, and necessary interventions must be undertaken at the earliest to avoid further irreversible brain damage.Keywords
