Objective: To investigate clinical experience of treatment for complex intracranial aneurysms of stent implantation combined with coil embolization about the efficacy. Methods: Twenty-six patients (totally 30 aneurysms) with complex intracranial aneurysms were treated with stent implantation combined with coil embolization. Patients were followed-up for 6-24 months. Results: After endovascular treatment, instant angiography demonstrated total occlusion in 24 aneurysms, more than 95% occlusion in 4 aneurysms and partly occlusion in 2 aneurysms. No re-bleeding or symptoms related to thrombosis occurred during instant angiography. Recurrent aneurysm was detected in 2 patients during following-up, while no migration, collapse nor narrowing of stent occurred. The parent arteries were open and smooth. Conclusion: For the treatment of complex intracranial aneurysms, the stent-assisted techniques are safe and effective. The selection of proper technique should base on individual condition of the patient.
