Complete neck closure of aneurysms having thick-walled necks is difficult. To make clipping safer and surer, we have developed a modified fenestration clip, which has a 1-mm wide slit-like fenestration with 5 mm long closing tip of blades. We used this clip in cases having a thick-wall aneurysm. Complete clipping was achieved in all patients without technical complications. Slit-shaped fenestration was useful for controlling the neck and dome and also for securing of the surgical field.
Aneurysm formation and tip closure technique are safely and precisely achieved with the modified clip in a thick-wall aneurysm.
