壁硬化性脳動脈瘤に対する改良型有窓クリップ(スリットクリップ)の有用性(手術手技)  [in Japanese] Usefulness of Modified Fenestration Clip (Slit-Clip) for Thick-Wall Aneurysms(Technical Note)  [in Japanese]

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 slitlike 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.
