This report describes the radiologic appearance of the intravenous oxygenator (IVOX), an intracorporeal CO2-O2 exchanger for use in patients with severe respiratory deficiency, and the extensive radiographic and sonographic support required for its use. Six patients aged 19-39 years who had severe adult respiratory distress syndrome (ARDS) and who were not expected to survive were selected for IVOX placement; ARDS was caused by trauma (four patients), severe pneumonia (one patient), or a fat embolus from a tibial fracture (one patient). Before insertion of the IVOX, all patients underwent evaluation of their right internal jugular vein, right common femoral vein, and inferior vena cava with real-time ultrasound (US) to ascertain vascular size. The IVOX improved oxygenation in all patients; because of such improvement, one patient survived. Use of the IVOX may become common; hence, radiologists should understand how the IVOX functions and its appropriate placement, be able to identify it on chest and abdominal radiographs, and appreciate the importance of US in placement of this device and follow-up.
本报告描述了静脉内氧合器（IVOX）的放射学表现，这是一种用于严重呼吸功能不全患者的体内二氧化碳-氧气交换器，以及其使用所需的广泛的放射学和超声检查支持。选择了6例年龄在19至39岁之间、患有严重成人呼吸窘迫综合征（ARDS）且预计无法存活的患者进行IVOX植入；ARDS由创伤（4例患者）、严重肺炎（1例患者）或胫骨骨折后的脂肪栓塞（1例患者）引起。在植入IVOX之前，所有患者均接受了实时超声（US）对右颈内静脉、右股总静脉和下腔静脉的评估，以确定血管大小。IVOX改善了所有患者的氧合；由于这种改善，1例患者存活。IVOX的使用可能会变得普遍；因此，放射科医生应了解IVOX的功能及其合适的放置位置，能够在胸部和腹部X线片上识别它，并认识到超声在该装置放置和随访中的重要性。
