A Novel Endovascular Treatment of a Wide-Necked Basilar Apex Aneurysm by Using a Y- Configuration, Double-Stent Technique

Summary: Wide-necked bifurcation aneurysms remain a formidable challenge to the neuroendovascular surgeon. A 36-year-old woman with a wide-necked basilar bifurcation aneurysm was unsuccessfully treated by endovascular methods, despite the use of the balloon-remodeling tech-nique. Successful coiling was ultimately achieved by use of a Y-configuration double stent-assisted technique. This novel method of using self-expanding stents may represent a significant advance in the management of basilar apex and other bifurcation aneurysms. Recent advances in endovascular techniques have greatly expanded the scope of intracranial aneurysms amenable to endovascular obliteration. The tech-nique of balloon remodeling and the development of a self-expanding stent for intracranial use allow fo
