Correct placement of the Avalon Elite Bicaval Dual Lumen catheter (Avalon Laboratories, LLC, CA) for single-site venovenous extracorporeal membrane oxygenation (VV ECMO) is safe using image guidance. Using this technique, 26 of 27 patients (96%) had uneventful placement of the cannula in the right internal jugular vein. One patient had a superior vena cava injury during serial dilation, and another patient required cannula repositioning for improved flows. We recommend using both fluoroscopy and transesophageal echocardiogram (TEE) for training purposes or during initial use of the Avalon Elite. As proficiency improves, TEE at the bedside provides an excellent standard of care. Double-lumen ECMO catheters can be effectively placed under image guidance with minimal need for repositioning.
使用影像引导技术，安全地将 Avalon Elite Bicaval 双腔导管（Avalon Laboratories，LLC，加利福尼亚州）放置在右侧颈内静脉，用于单部位静脉-静脉体外膜肺氧合（VV ECMO）。27 例患者中有 26 例（96%）的导管在右颈内静脉中进行了顺利的放置。1 例患者在连续扩张过程中出现上腔静脉损伤，另 1 例患者需要重新定位导管以改善血流。我们建议在使用 Avalon Elite 时，无论是出于培训目的还是初次使用，均同时使用透视和经食管超声心动图（TEE）。随着熟练程度的提高，床边 TEE 可提供出色的护理标准。双腔 ECMO 导管可在影像引导下有效地放置，无需多次重新定位。
