For patients with pituitary tumors, a range of complications, sequelae, or concomitant ailments can easily occur after surgery. For instance, postoperative sellar hematoma may occur, and some patients may even experience the rupture of a pseudoaneurysm. Additionally, some patients may repeatedly suffer from headaches, dizziness, nausea, vomiting, and weakness in the limbs after surgery, along with significant memory decline, reduced cognitive function—including calculating ability, and orientation in time, space, and person—gradually diminishing. These are considered postoperative sequelae of pituitary tumor surgery.
