title: Intra-aneurysmal microcatheter looping technique for stent-assisted embolization of complex intracranial aneurysms.
abstract: The endovascular treatment of wide-necked, large and giant aneurysms remains challenging. This retrospective study investigated the feasibility and safety of an intra-aneurysmal microcatheter looping technique for stent-assisted embolization of complicated intracranial aneurysms.This technique was used for 31 patients with complicated cerebral aneurysms from January 2007 to November 2013. The clinical and angiographic results were retrospectively evaluated.The target aneurysms were successfully treated in all cases (100%). A flow diverter was used in seven procedures. There were no aneurysmal perforations or ischemic complications, except for a microguidewire perforation of the distal vessel in one case. Among the 24 cases with conventional stent-assisted embolization, complete embolization or neck residual was obtained in 21 cases. Partial occlusion occurred in three cases.In conclusion, the intra-aneurysmal microcatheter looping technique is a safe and feasible alternative treatment of complicated intracranial aneurysms. This approach is a reasonable choice for patients and leads to successful outcomes.
