Hemorrhagic complications occured in 4 patients, due either to aneurysmal perforation during coiling (n=2) or to perforation of a distal branch with a microguidewire (n=2). Further thrombus extension was seen in 5 patients requiring a treatment with Reopro to restore a normal flow. Postcoiling stenting was achieved in 5 patients, due to coil instability in 3 patients or thrombus extension in 2. Failure to place both balloons occured in 2 procedures. Results: Placement of both balloons was possible in 98 cases, allowing total or sub-total occlusion of the aneurysm. Different remodelling balloons were used (Hyperform, Eclipse, Hyperglide, Copernic).
The aneurysms were located at the MCA bifurcation (n=64), anterior communicating artery (n=15), posterior communicating artery (n=7), basilar artery (n=12) and carotid bifurcation (n=2). The aneurysms were unruptured (n=59), recanalized (n=30) or ruptured (n=11). Materials and Methods: A treatment by kissing balloon technique was attempted in 100 aneurysms harbouring a very broad neck. The purpose of this study is to determine the efficacy of this technique. An alternative may be the kissing balloon technique with the combined used of two remodelling ballons.
If none of these techniques are applicable, surgical clipping is usually achieved. Purpose: Broad neck aneurysms may be treated by various techniques including 3D coils, balloon remodelling, trispan or stent.
