頸動脈ステント留置術におけるガイディングカテーテルの保持を目的としたgoose neck snareの使用

Usefulness of the Goose Neck Snare for Holding the Guiding Catheter for Carotid Artery Stenting

Ⅰ．はじめに

　頸動脈ステント留置術（carotid artery stenting :CAS）では，親カテーテルを病変の近位部で保持する必要がある．安定した親カテーテルの保持が困難な症例では，上腕動脈経由のgoose neck snareにて良好な位置に親カテーテルを保持する方法が有用である．

　A goose neck snare is a useful device not only for the retrieval of intravascular foreign bodies, such as detachable coils and catheter fragments, but also for holding a guiding catheter. In carotid artery stenting, the guiding catheter should be kept stable in the proximal of the stenotic lesion, but it is sometimes difficult because of the tortuousity of the proximal common carotid artery. We present a case of carotid artery stenting for proximal part common carotid artery stenosis and discuss the usefulness of the goose neck snare from the brachial artery for holding the guiding catheter.
