Anatomic results were measured by statistical analysis of variance for such factors as age, sex, presence of subarachnoid hemorrhage, anatomic type (ophthalmic or superior hypophyseal), size of aneurysmal sac, and width of aneurysmal neck. Clinical evaluation and control angiography were performed at 6 and 18 months.RESULTS Overall, complete occlusion was obtained in 14 aneurysms (50%) and small residual necks were left in 11 aneurysms (39%). Three treatment attempts failed (11%). Complete occlusion was obtained in 76% of small-necked aneurysms as opposed to 9% of aneurysms with a large neck. The best predictor of anatomic result was the size of the aneurysmal neck. Complete occlusion was obtained in 85% of superior hypophyseal aneurysms of the paraclinoid variant. One permanent complication was related to treatment.CONCLUSION Endovascular treatment with GDCs appears to be a safe and efficient alternative approach for ophthalmic segment aneurysms, especially for paraclinoid variants of superior hypophyseal aneurysms, which tend to have a small neck.
