Elective Treatment of Saccular and Broad-necked Intracranial Aneurysms using a Closed-cell Nitinol Stent (Leo)Neurosurgery, 58
BACKGROUND AND PURPOSE: Stent systems for intracranial use are continuously improved. We report our initial experience using a new self-expanding easy-to-place nitinol stent (Enterprise) in the treatment of wide-neck intracranial aneurysms. MATERIALS AND METHODS: Between January and October 2007, 16 aneurysms in 15 patients were treated with stent assistance. Aneurysm size was a mean of 13.2 mm (median, 12 mm; range, 7–30 mm). Eight aneurysms had reopened after prior coiling, and 8 aneurysms were primarily treated, 1 after acute subarachnoid hemorrhage. Response to antiplatelet premedication was tested with a P2Y12 assay before stent placement. On a 3D angiographic workstation, stent placement was simulated to assess vessel caliber and appropriate stent length. RESULTS: In all aneurysms, the stent could be placed at the exact location as predicted from the computer simulation. Stent placement proved to be technically easy without the need for recapture in all patients. Although placement of the microcatheter through the stent struts and subsequent coil placement was challenging in some patients, coiling after stent placement resulted in complete or near-complete occlusion in all aneurysms. There were no technical or clinical complications. At 6 months, angiographic follow-up in 14 aneurysms revealed 4 aneurysms recanalized to 80% occlusion, 3 of which were additionally coiled. CONCLUSION: In this small series, delivery and deployment of the Enterprise stent was technically easy. There were no technical or clinical complications. The device was valuable in the treatment of wide-neck aneurysms. The need for antiplatelet medication in patients treated with this and other stents remains a significant disadvantage.
