A Survived Case of Acute Bilateral Internal Carotid Artery Occlusion Treated by Mechanical Thrombectomy

OBJECTIVE: We report a survived case of acute bilateral internal carotid artery occlusion successfully treated by mechanical thrombectomy. CASE PRESENTATION: The patient was an 82-year-old right-handed man. Sudden consciousness disturbance and aphasia appeared, and cranial magnetic resonance angiography (MRA) revealed bilateral internal carotid artery occlusion. Cerebral angiography demonstrated occlusion between the cervical and cavernous portions of the bilateral internal carotid artery, and the growth of collateral circulation to the areas where the bilateral internal carotid artery perfused. We performed mechanical thrombectomy first on the left side, which was the main cause of his symptoms and relatively wide ischemic penumbra, and achieved recanalization of the bilateral internal carotid artery and suppressed extensive enlargement of the infarction. CONCLUSION: Acute bilateral internal carotid artery occlusion requires an optimal treatment strategy based on the clinical symptoms and preoperative imaging.
