OBJECTIVE: To study the surgical principles and treatment options of intracranial aneurysms. METHODS: One hundred and thirty nine patients with intracranial aneurysms were retrospectively studied, including 80 open-surgery cases and 59 endovascular-treated cases from January to December in 2009. Open surgical methods included clipping, trapping or wrapping and interventional methods included simple coiling or stent-assisted coiling. Intra-operative electroencephalogram and somatosensory evoked potentials monitoring were regularly used. Microvascular doppler ultrasonography and indocyanine green videoangiography were used to assess blood flow in parent and branch vessels. RESULTS: Seventy-three aneurysms were directly clipped, 6 were trapped and 1 was wrapped. Thirty-three aneurysms were coiled and 26 were coiled assisted with stents. At discharge, 71 of the 80(88.8%) surgical treated patients had Glasgow Outcome Scale score of 4 or 5 points, 3 points in 6 patients (7.5%), 2 points in 1 patient (1.2%), and 1 point in 2 patients (2.5%). Fifty-four out of 59 cases underwent endovascular treatment scored 4 or 5 points (91.5%) and 3 points in 5 patients (8.5%). CONCLUSIONS: Surgical clipping and endovascular coiling are two major treatment choices for intracranial aneurysms. The treatment option should be individualized based on the patients' specific conditions, which could have a safe, effective and durable outcome.
