A Case of Left Carotid Artery Injury

Invasive pituitary adenomas can infiltrate the dura mater, sphenoid sinus, or cranial bone. Endoscopic transsphenoidal sinus surgery is considered the standard of care; however, several potential complications must be noted. These complications can include cerebrospinal fluid leaks, infection, bleeding, optic nerve damage, and endocrinological complications such as diabetes insipidus. We present a case of a 69-year-old female with multiple recurrent invasive pituitary adenomas who has previously undergone 5 transsphenoidal procedures. Intraoperatively, the patient suffered from a left-sided carotid artery injury that was repaired with a muscle graft. Management of carotid artery injury during transsphenoidal surgery is optimized in a step-by-step approach which includes early recognition of the injury, briefing the surgical team, immediate control using compression, use of additional tissue graft for wound repair, and postoperative care. Through the use of the approach mentioned above, we were able to control the complication successfully.
