A 47-year-old man sustained multisystem injuries after being struck by a vehicle travelling at high speeds. Shortly after admission to the emergency department he suffered a ventricular tachycardia/ventricular fibrillation cardiac arrest lasting 30 min. Investigations following return of spontaneous circulation raised suspicion for an anterolateral ST-elevation myocardial infarction. Despite his major traumatic injuries the patient was transferred for percutaneous coronary intervention uncovering a complete thrombosis of the ostium of the left anterior descending artery. Immediately following coronary revascularisation, the patient developed cardiogenic shock resulting in a multidisciplinary decision to place the patient on veno-arterial extracorporeal membrane oxygenation (VA-ECMO). The management of cardiogenic shock due to acute myocardial infarction with VA-ECMO and multiple traumatic injuries were often at odds with each other, resulting in a series of challenging decisions on timing of surgery and anticoagulation. The patient was liberated from VA-ECMO after 72 hours and continues rehabilitation in hospital.
一名47岁男性被高速行驶的车辆撞击后受到多系统损伤。在急诊入院后不久,他发生了持续30分钟的室性心动过速/心室颤动心脏骤停。自主循环恢复后的检查引起了对前侧壁ST段抬高型心肌梗死的怀疑。尽管患者有严重的创伤性损伤,但仍被转至进行经皮冠状动脉介入治疗,结果发现左前降支动脉开口完全血栓形成。冠状动脉血运重建后,患者立即出现心源性休克,导致多学科团队决定为患者进行静脉-动脉体外膜肺氧合(VA-ECMO)治疗。VA-ECMO治疗急性心肌梗死所致心源性休克与多处创伤性损伤的处理常常相互矛盾,导致在手术时机和抗凝方面做出一系列具有挑战性的决策。患者在72小时后脱离VA-ECMO,目前仍在医院接受康复治疗。
