[A case of treatment on traumatic pseudoaneurysm of internal carotid artery occurred epistaxis].

We reported a case of traumatic pseudoaneurysm of internal carotid artery accompanied by skull base fracture, for which Guglielmi detachable coil(GDC) embolization surgery was very effective for recovery. A 53-year-old man met a traffic accident and was admitted to our hospital with blindness and epistaxis accompanied with shock. Balloon occlusion test showed a positive sign of traumatic pseudoaneurysm of internal carotid artery, and under the diagnosis GDC embolization surgery was performed on six days after the onset. The patient has completely recovered and keeps his wellness untill now after six months from the surgery except for loss of left eye vision. We believe that the endovascular surgery using stents will become the prime modality for treatment of traumatic pseudoaneurysm in the future.
