Basilar artery occlusion due to vertebral artery injury treated with thrombectomy and distal vertebral artery embolization through the unaffected side.

In the case of vertebral artery injury, preparation for early occlusion of the basilar artery is necessary. If a thrombus and collateral blood flow are present distal to the vertebral artery injury, distal vertebral artery embolization may be necessary to prevent embolism.
