Abstract
脳動脈瘤に対する顕微鏡手術下のネッククリッピングは脳動脈瘤破裂の危険を著しく低下させる治療としてその有効性が確立されており,脳神経外科手術の基本である.ネッククリッピングとは正常の血管の形状,走行を保ちながら脳動脈瘤を血流から分離することであり,脳動脈瘤のネックに単にクリップをかけることではない.その目的を安全に達成するためには,適切な体位取り,必要十分な術野の確保,適切なクリップの選択などが重要となる.本稿では脳動脈瘤手術における基本について概説する.
Microsurgical clipping for cerebral aneurysms should be performed under adequate preparations and proper clipping techniques. The patient's head position and surgeon's posture should be determined to minimize brain retraction and ensure the smooth and safe use of surgical tools. The operative field should be wide enough to perform safe and stable clipping, which mainly depends on the surgeon's skills. Proper clips should be applied to proper positions to maintain normal blood flow of parent arteries and preserve perforators. Surgeons must have precise knowledge about materials and mechanical characteristics of clips to avoid incomplete clipping, unnecessary artifacts and side effects.
