Stent-assisted coiling embolization of middle cerebral artery trifurcation wide-necked aneurysms.

OBJECTIVE

The aim of this study was to examine the effects of stent-assisted coiling embolization of middle cerebral artery (MCA) trifurcation wide-necked aneurysms in clinical practice.

PATIENTS AND METHODS

57 patients with MCA trifurcation wide-necked aneurysms underwent stent-assisted coiling embolization using a solitaire AB stent. All 57 patients completed the surgery successfully. Embolization efficacy was graded according to the modified Raymond scale.

RESULTS

There were 52 cases of complete embolization, 4 cases of residual aneurysm neck, and 1 case of residual aneurysm body. 50 patients participated in a 6-36-month follow-up. There has not been observed any aneurysm rupture and hemorrhage. 50 patients received digital subtraction angiography (DSA) re-examination; 46 patients presenting complete embolization had no aneurysm relapses; 3 patients had residual aneurysm neck demonstrated; 1 patient had no aneurysm neck and others 2 were in stable condition. Finally, the patient with residual aneurysm body showed no sign during follow-up reexamination.

CONCLUSIONS

Stent-assisted coiling embolization of intracranial wide-necked aneurysms using the solitaire AB stent was safe and effective.
