Key Points

To clarify the long-term outcomes of microsurgical ligation of unruptured intracranial aneurysms and the significance of postoperative follow-up.
Evaluated the incidence of subarachnoid hemorrhage after surgery
Assessed risk factors associated with postoperative complications
Identified specific risk factors that increase the likelihood of subarachnoid hemorrhage
Provided insights into the importance of continuous postoperative monitoring

Implication

Long-term outcomes of microsurgical treatment for unruptured intracranial aneurysms highlight postoperative risks and follow-up importance.

Abstract
