Procedure-induced acute common carotid artery perforation presenting with airway obstruction and successful treatment by endovascular stent graft.

A 63-year-old female was admitted to our hospital for catheter ablation during atrial fibrillation. After catheter ablation, the patient was transferred to the cardiac care unit and mechanically ventilated due to dyspnea and hypotension. Imaging showed active bleeding from the right common carotid artery (CCA) with extensive hematoma into the mediastinum. She was successfully treated with a stent graft at the CCA. Further bleeding or neurologic sequel did not occur after treatment.
