In wide-neck intracranial aneurysms located at arterial bifurcation and small parent arteries, the standard remodeling technique of balloon-assisted coil embolization remains challenging. A new, more compliant remodeling balloon microcatheter has been developed for the treatment of these difficult aneurysms. We report coil embolization by the use of the remodeling technique with HyperForm balloon in 19 consecutive patients (with 21 aneurysms) with these difficult aneurysms. Twenty-one aneurysms consisted of 18 unruptured aneurysms, 2 ruptured aneurysms and 1 symptomatic aneurysm. Coil embolization was successfully performed in 18 of 19 patients (in 20 of 21 aneurysms). Angiographic results in 20 aneurysms showed 16 complete occlusions, 2 neck remnants and 2 residual flows. Sixteen patients presented excellent clinical outcomes. The HyperForm balloon microcatheter allows the treatment of difficult wide-neck aneurysms located at arterial bifurcation and small parent arteries.
