ガイディングカテーテルの保持にgoose neck snareを使用し非破裂血栓化巨大椎骨動脈瘤に対する塞栓術を施行した1例

A Case of Parental Artery Occlusion for a Non-ruptured Giant Thrombosed Aneurysm at the Right Vertebral Artery Using a Goose Neck Snare to Hold a Guiding Catheter

Ⅰ．はじめに

　血管内治療の際に，アクセスルートの蛇行が強い症例では，ガイディングカテーテルを目的の位置に上手く留置できずに，その後の手技が難しくなることをしばしば経験する．今回，われわれは非破裂血栓化巨大紡錘状椎骨動脈瘤に対して母動脈閉塞術を行う際に，goose neck snareを用いてガイディングカテーテルの安定を図り，良好な結果を得た1例を経験したので報告する．

　The stabilization of a guiding catheter is one of the important factors for achieving successful endovascular treatments. However,obtaining sufficient stabilization is sometimes difficult due to the tortuousity of the approach route. A goose neck snare is useful not only for the retrieval of intravascular foreign bodies but also for holding a guiding catheter. This report presents a case of parental artery occlusion for a non-ruptured giant thrombosed aneurysm occurring in the right vertebral artery using a goose neck snare to hold a guiding catheter.
