For patients with pituitary tumors, undergoing pituitary tumor surgery carries certain risks. The main risks are due to the important blood vessels, nerves, and various crucial structures around the pituitary tumor. Careless maneuvers during the surgery may damage these important organs or affect the surrounding crucial blood vessels, leading to potentially fatal massive bleeding. Additionally, some common surgical risks may also exist, such as anesthesia accidents, postoperative intracranial infections, cerebrospinal fluid rhinorrhea, and other conditions. Therefore, for pituitary tumor patients, it is necessary to prepare thoroughly for the surgery and make a comprehensive assessment of the patient's overall condition before the procedure.
