We report a new approach to preoperative vascular exclusion of a carotid body tumor. Before surgery, covered stents were placed in the external carotid artery, resulting in vascular exclusion of the tumor. Subsequent surgical excision was uneventful, with operative blood loss less than 200 mL and no neurologic complications postoperatively. This technique deserves further consideration as a reasonable alternative to conventional embolization.

A three-year old girl who initially presented at 16 months with epistaxis from an anterior skull base vascular anomaly returned with near-fatal epistaxis despite embolization of the internal maxillary artery at the time of initial presentation. Repeat angiography demonstrated blood supply to the vascular lesion coming from branches of both the external and internal carotid arteries. The patient underwent four sessions of endovascular embolization with polyvinyl alcohol, alcohol, and gelatin microspheres. At the conclusion of treatment, her epistaxis had resolved and the only residual blood supply to the lesions came from bilateral ophthalmic arteries intentionally not sacrificed to prevent loss of vision. Endovascular embolization of both the internal and external carotid arteries is a challenging but important treatment option for life-threatening epistaxis resulting from vascular lesions of the skull base.
