{Abstract}: <B>BACKGROUND: </B>Iatrogenic pseudoaneurysms arising from the internal carotid artery subsequent to carotid endarterectomy are exceptionally infrequent. Herein, we present a case detailing an internal carotid artery pseudoaneurysm that manifested subsequent to a hybrid carotid endarterectomy and endovascular therapy intervention. Our approach to managing this condition involved a novel technique wherein thrombin was directly injected into the luminal cavity of the pseudoaneurysm under the guidance of a C-arm.<BR><B>METHODS: </B>A 66-year-old male patient of Chinese ethnicity exhibited a 4-month history of headache and a 20-day history of gait disturbance. Digital subtraction angiography revealed occlusion in the cervical region of the left carotid artery. Following a hybrid surgical procedure, the patient reported mild pain and bruising surrounding the incision site of the left internal carotid artery endarterectomy. Subsequent angiography identified the presence of a carotid artery pseudoaneurysm. Utilizing C-arm guidance, thrombin was then directly injected into the luminal cavity of the pseudoaneurysm, resulting in complete healing during follow-up.<BR><B>CONCLUSIONS: </B>For the management of pseudoaneurysms arising post carotid endarterectomy, the direct injection of thrombin into the aneurysm cavity under the guidance of a C-arm is deemed both safe and efficacious.
