難治性不整脈に対し星状神経節ブロックが奏功した1症例

Refractory Arrhythmia Successfully Treated with Stellate Ganglion Block

要旨

　80歳，男性，低心機能・心不全・心筋虚血で心室頻拍，心室細動を繰り返しelectrical storm（ES）の状態となった。経皮的冠動脈形成術（percutaneous coronary intervention：PCI），補助循環の併用，アミオダロンやニフェカラント投与後も改善せず，星状神経節ブロック（stellate ganglion block：SGB）施行で難治性不整脈が軽減した。

　An 80-year-old Japanese man with low cardiac function, heart failure, and myocardial ischemia exhibited repeated ventricular tachycardia and ventricular fibrillation, resulting in an electrical storm. His condition did not improve even after percutaneous coronary intervention, assisted circulation, and the administration of amiodarone and nifekalant. A stellate ganglion block resolved the patient’s refractory arrhythmia.
