Clipping of Unruptured Intracranial Aneurysms in Patients on Maintenance Dialysis: Results and Precautions

As the number of patients undergoing maintenance dialysis (MD) increases over time, the number of those with unruptured intracranial aneurysms is also assumed to increase. Treatment results and perioperative measures for unruptured intracranial aneurysmal clipping with MD at our hospital have been reported. Ten patients (11 surgeries) with MD treated by clipping of unruptured intracranial aneurysms in 17 years from January 2002 to December 2018 were examined. Clipping was completed in all cases. Of the 11 procedures, postoperative morbidity was observed in eight cases (73%). Among them, the most common complication was acute symptomatic seizure in seven patients (64%). The onset of acute symptomatic seizures was limited to within two days after surgery, and there were no prolonged cases. We concluded that patients undergoing aneurysmal clipping on MD are more likely to have postoperative acute symptomatic seizures than those without MD. Therefore, perioperative measures and informed consent focusing on the risk of postoperative seizures are required.
