For patients with pituitary tumors, it is common to see certain complications, especially post-surgery, such as hematoma in the sellar region, life-threatening nasal hemorrhage, pseudoaneurysm rupture bleeding, cerebrospinal fluid rhinorrhea, meningitis, reduced pituitary function, diabetes insipidus, as well as associated issues with fluid, electrolyte imbalance, and acid-base imbalance. Some patients may also experience rare complications like eye muscle paralysis and nasal septum perforation. Therefore, for patients with pituitary tumors, it is crucial to closely monitor any changes in their condition after surgery. If any abnormalities are found, a prompt re-examination with a head CT should be conducted to observe changes and provide appropriate treatment.
