Abstract:

Objective    To analyze the characteristic of ruptured intracranial micro-aneurysm and evaluate outcomes of clipping and endovascular treatment. Methods    45 patients with ruptured intracranial micro-aneurysm received clipping (n=28) or endovascular treatment (n=17).Their complications，recurrence rates and Glasgow outcome scale（GOS） scores at discharge were evaluated. Results    There were 45 aneurysms, 84.44％ of which were wide-necked aneurysms. There was a statistical difference in the occurrence rate of complications（P<0.05）， while there was no statistical difference in the recurrence rate，Hunt-Hess grade and GOS score（P>0.05） between the clipping group and the endovascular treatment group. Conclusion    Most ruptured intracranial micro-aneurysms are wide-necked aneurysms. Clipping and endovascular treatment are feasible methods to treat ruptured intracranial micro-aneuryam.
