Early hyperbaric oxygen therapy for cerebral air embolism during atrial fibrillation ablation

Abstract: Cerebral air embolism is a potentially life-threatening complication of left-sided ablation procedures. We present a 51-year-old woman with cerebral air embolism during atrial fibrillation cryoballoon ablation. Taking a deep breath while removing the dilatator was the most likely mechanism in our case. The patient was successfully treated with hyperbaric oxygen therapy at early stage and was discharged without any neurological sequelae.

“…2 Embolization of air may be treated by several methods, such as 100 % oxygen therapy to maximize end organ damage and reducing the size of air embolus, aspiration of the air or hyperbaric oxygen therapy. 3,5,8 A different and exraordinary treatment approach is using pigtail catheter to disperse too large air bubble as our case. Numerous manipulations to prevent air embolism are removal of catheters and dilators slowly, continuous flushing with heparinized saline, avoiding deep sedation, decreasing number of catheter exchanges, reevaluate hemostatic valves, and sheath flushing at slow speeds.…”

“…Embolism of air to the vessel tree may be due to inserting catheters into the circulatory system or may be occurring of atrial-esophageal fistula during and/or after AF ablation. [3][4][5] This is a disastrous complication which can lead to death. The catheters are major reason of air embolism in acute settings.…”

“…脳空気塞栓症を疑う患者には,迅速な診断と治療が求められる。診断には画像検査が有用であるが,空気塞栓症の空気陰影は0.5~30時間で消失するため,速やかに撮像することが診断の一助となる 19)。治療では本症例同様に頭低位および左側臥位への体位変換を行うことが塞栓の進行を抑えることに有用とされている 4)。また,高濃度酸素投与や高気圧酸素療法(hyperbaric oxygenation therapy: HBO)も効果があるとされているが,同治療の有効性を確認した無作為化比較試験は実施されておらず 17),脳空気塞栓症に対する治療効果については一定の見解が得られていない。HBOが適応となる場合には,神経症状出現より4~6時間以内に開始すべきであり 20),転院搬送も含めた迅速な対応が必要となる 4)。最後に萩原らは,血行動態が破綻し,心停止に至った最重症の空気塞栓症に対し,空気の除去および心肺蘇生を目的としてveno–arterial extracorporeal membrane oxygenation(ECMO)を導入し,一定の治療効果を得たと報告している 5)が,同時に彼らは同蘇生法自体がシャントとして動脈性空気塞栓症を助長させる可能性も指摘している。心停止に至るほどの最重症空気塞栓症に対するECMO導入については,今後,さらに議論を深める必要がある。…”
