Treatment of Iatrogenic Internal Carotid Artery Laceration and Carotid Cavernous Fistula with Endovascular Stent-Graft Placement

摘要

Summary: The risk of fatal injury of the internal carotid artery (ICA) and surrounding anatomy during transsphenoidal surgery for pituitary adenoma is the most severe potential complication associated with this particular approach. We present a case in which iatrogenic injury to a patient’s ICA and resultant carotid cavernous fistula and massive hemorrhage was successfully managed with the emergency placement of an endovascular stent-graft. Both findings in the relevant literature and practical considerations concerning both stent-grafts and other more commonly used options for the treatment of iatrogenic ICA injury are discussed.
