Vascular injury is a common complication in firearm injuries; however, intravascular missile embolism is relatively rare. There are only 38 documented cases of intravascular missile embolisation to the heart. Bullet embolisms are difficult to diagnose even with multiple diagnostic modalities and even once identified, the most optimal choice of surgical management is debated. Our patient presented with a gunshot wound to the right posterior shoulder. Cardiac focused assessment with sonography for trauma, chest X-ray, CT and echocardiogram were performed, showing missile location adjacent to the right ventricle with inconclusive evidence of pericardial injury. Exploratory median sternotomy was performed, revealing intact pericardium and injury to the superior vena cava (SVC) with bullet embolisation to the right ventricle. The patient became temporarily asystolic secondary to haemorrhage from the SVC injury. Cardiac massage was performed, dislodging the missile into the inferior vena cava. A venotomy was performed to retrieve the bullet and vascular injuries were primarily repaired.
血管损伤是火器伤的常见并发症;然而,血管内弹丸栓塞相对较少见。仅有 38 例经证实的血管内弹丸栓塞至心脏的病例。即使使用多种诊断方式,也很难诊断出弹丸栓塞;即使确定了诊断,手术管理的最佳选择仍存在争议。我们的患者因右侧后肩部枪伤就诊。进行了心脏创伤超声重点评估、胸部 X 线、CT 和超声心动图检查,显示弹丸位置紧邻右心室,心包损伤的证据不明确。进行了正中胸骨切开术,发现心包完整,上腔静脉(SVC)损伤,弹丸栓塞至右心室。由于 SVC 损伤导致出血,患者暂时出现心动停止。进行了心脏按摩,将弹丸移位至下腔静脉。进行了静脉切开术以取出子弹,并对血管损伤进行了初步修复。
