TRAUMATIC CAROTID-ARTERY DISSECTION AND PSEUDOANEURYSM TREATED WITH ENDOVASCULAR COILS AND STENT

Purpose: To report a case of post-traumatic internal carotid artery di ssection and pseudoaneurysm formation at the C-l level successfully tr eated by a percutaneous endovascular technique. Methods and Results: A 20-year-old female presented 72 hours after a motor vehicle accident with incomplete occulosympathetic paresis (Horner's syndrome), carotid ynia, and left-sided weakness. Arteriography confirmed the diagnosis o f carotid dissection and an associated 1.5-cm x 2.5-cm pseudoaneurysm at the C-l level. Neuroradiologists embolized the pseudoaneurysm with Guglielmi detachable coils and controlled the dissection with placemen t of a Wallstent. Conclusions: This report illustrates successful perc utaneous endovascular treatment of a carotid dissection and pseudoaneu rysm near the base of the skull.
