Objective To study the therapeutic effect of Onyx combined with stent-assisted coiling in embolizing complex intracranial ruptured aneurysms. Methods Onyx combined with stent-assisted coiling embolization was conducted in two patients with complex intracranial ruptured aneurysms. The clinical data were retrospectively analyzed. The related literature concerning intracranial complex aneurysm treated with Onyx was reviewed. Results Two intracranial complex aneurysms were embolized with Onyx together with coils. The lesions were located at internal carotid arterial bifurcation (n = 1) and at the anterior wall of intemal carotid artery (n = l). Complete embolization of the aneurysms was achieved immediately after the procedure while the parent arteries remained patent. Conclusion For the treatment of complex intracranial ruptured aneurysms Onyx combined with coiling embolization is safe, effective and feasible. This technique can improve the degree of' embolization. To make the evaluation of the long-term efficacy further study is needed.
