・前方循環急性期脳梗塞に対する血栓回収療法では,バルーン付きガイディングカテーテル(BGC)使用は標準的手技である一方で,エビデンスは不明確である.
・BGC使用の主目的は遠位塞栓症の予防であるが,誘導時や遠位血管にデバイスを送達する際のアンカーとしてバルーンを拡張させるテクニックがある.
・後方循環閉塞例や橈骨動脈アプローチの際には従来型ガイディングカテーテルが用いられることが多い.
A balloon guide catheter (BGC) is commonly used for thrombectomy in acute ischemic stroke (AIS) of the anterior circulation. However, the findings supporting BGC usage remain unclear. The primary purpose of BGC use is preventing embolization in a new area; the BCG is also used as a balloon expansion technique to anchor devices during navigation and delivery to distal vessels. Conventional guide catheters are often used in cases of posterior circulation occlusion or with a transradial approach. Balloon and conventional guide catheters are reviewed, providing evidence supporting their use in treating AIS, describing the characteristics of each, and outlining guidelines for selecting the most appropriate guide catheter.
