title: [Effects of Endovascular Treatment on Cranial Nerve Palsy due to Unruptured Intracranial Aneurysms].
abstract: This study aimed to assess the effects of endovascular treatment on cranial nerve palsy due to unruptured intracranial aneurysms. Endovascular coiling was performed in 203 patients with intracranial aneurysms between April 2002 and March 2012 in our hospital. Of these patients, 8(3.9%)presented with cranial nerve palsy due to unruptured intracranial aneurysms. Cranial nerve palsy involved the oculomotor nerve in 8 patients and the optic nerve in 2 patients. Two patients had both optic nerve and oculomotor nerve dysfunction. Patients with incomplete oculomotor nerve palsy at admission were more likely to have full recovery after coiling. Optic nerve dysfunction did not improve after coiling. Incomplete oculomotor nerve palsy, early treatment(≤15 days), and small aneurysms(≤10 mm)were likely to be associated with complete recovery after coiling. This study indicates that endovascular coiling may resolve cranial nerve palsy due to unruptured intracranial aneurysms in patients who have incomplete oculomotor nerve palsy due to small aneurysms and are treated as early as possible after symptom onset.
