Abstract:
Objective: To review the surgical modality with pterional keyhole approach in treatment of anterior circulation aneurysm.Methods: Three hundred and thirteen patients with ruptured anterior circulation intracranial aneurysm treated surgically with pterional keyhole approach between January 2009 and June 2014 in Department of Neurosurgery, the Second Affiliated Hospital of Zhejiang University School of Medicine, were included in the analysis. Complete occlusion rate of aneurysms and incidence of major complications including delayed cerebral ischemia and chronic hydrocephalus were documented.Surgical outcomes at 6-month follow up were assessed by modified Rankin Scale.Results: Totally 348 aneurysms were treated with pterional keyhole approach, 326 aneurysms were completely clipped, 16 aneurysms were partly clipped, and 6 aneurysms were wrapped with gauze material. Among 313 patients, 15 patients (4.79%) suffered from delayed cerebral ischemia, and 10 patients (3.19%) suffered from hydrocephalus.At the 6-month follow up, the rate of good outcome was 66.77% (209/313).Conclusions: The pterional keyhole approach can be used to clip most of anterior circulation aneurysms, and it seems to have advantages over the traditional approaches with lower incidence of complications and similar outcomes.
