Is eyebrow approach suitable for ruptured anterior circulation aneurysms on early stage: a prospective study at a single institute.
OBJECTIVE
A prospective study was underway to evaluate the outcome of eyebrow keyhole approach for ruptured anterior circulation aneurysms on early stage.


METHODS
In the past 4 years, 88 patients with ruptured anterior circulation aneurysms, were operated on early stage by an experienced neurosurgical team through eyebrow craniotomy. The clinical data were analyzed.


RESULTS
Patients with Hunt and Hess Grade I-II (85.2%) or III (14.8%) were selected for eyebrow approach on early stage. All aneurysms were small (20.5%) or middle (79.5%) in size. All but seven (92.0%) aneurysms were clipped successfully. The opening of frontal sinus occurred in 11(12.5%) cases through eyebrow approach. Of all, 78 (88.6%) patients achieved favorable outcomes.


CONCLUSIONS
Eyebrow keyhole approach for ruptured anterior circulation aneurysms on early stage might be in particular selected according to the Hunt and Hess Scale, the projection of aneurysm, the length of M1 segment, the location of cerebral hematoma, the size and complexity of aneurysm, as well as the preference and experience of the neurosurgical team.
