Abstract:
Objective To evaluate the preliminary experience of the combined application of a self expanding neurovascular stent system (Neuroform stent) and detachable coils in the management of wide necked intracranial aneurysms. Methods Self expanding neurovascular stents and coils were used in the treatment of 32 patients. There were total 34 intracranial wide necked aneurysms in 32 cases including cavernous segment ICA aneurysms in 3, ophthalmic artery aneurysms in 3, PComA in 8, AcomA in 3, MCA bifurcation in 5, vertebral artery in 6, basilar tip in 1, basilar trunk in 2 and distal anterior cerebral artery aneurysm in 1. The Neuroform stents were deployed across the neck of aneurysm. Another microcatheter was introduced into the aneurysm sac in advance or through stent mesh and then detachable coils were released to embolize the aneurysms. Results Thirty four Neuroform stents were successfully deployed in 31 patients .Balloon inflation stent was used for 1 patient with basilar tip aneurysm after failure of getting the Neuroform stent through the stenotic PC. Total occlusion was achieved in 24 patients, residual neck in 6 patients and partial occlusion in 2 patients. In stent thrombosis occurred in 1 patient. Thirty one patients recovered well but with one death. Thirty patients were under clinical followed up from 1 to 6 months with an average of 4.7 months.There was no bleeding or thromboembolic events. Eleven patients were angiographically followed up for 3 months after the procedure, Among them, no filling was shown for the 7 aneurysms which were densely packed. Other 4 aneurysms with neck remnant including 2 stable and another 2 with disppeared neck. Conclusions The Neuroform stent with high flexibility is technically feasible and can be safely navigated into even distal small neurovasculature.The long term effect still need to be further investigated.
