OBJECTIVESTo analyse the characteristics of interventional treatment for anterior communicating artery aneurysm (AcoAA) and improve curative effects.

METHODSIn 126 patients, detachable microcoils were used to embolize the AcoAA via endovascular approach. Those patients failed to be embolized were treated by surgical clipping.

RESULTSOf the 109 patients who were embolized successfully, 97 were achieved 100% occlusion, 12 95% - 98% occlusion. In the other 17 patients who failed to interventional treatment 15 were treated surgically and 2 no treatment because of cerebral vascular spasm. 123 patients were cured, one died, and 2 had aneurysms disappeared without any operations, as proved by follow-up for 5 months to 1 years. Of 32 patients checked by cerebral angiography 3 weeks to 30 months after operation, 30 showed disappeared of aneurysms and 2 had recurrence. The recurred aneurysms were successfully reembolized.

CONCLUSIONSMost of AcoAAs can be cured by endovascular interventional treatment. Those who failed to be treated by embolization can be cured surgically. Few patients may be healed spontaneously. The long term effects of treatment should be followed-up for a long time.
