To describe the utility of transesophageal echocardiography (TEE) in a patient undergoing thoracoabdominal aneurysm (TAA) surgery using left atrio-femoral bypass (LAFB).
A 57-yr-old female patient underwent repair of type II TAA. As per institutional routine, LAFB technique was used. Initial difficulty with the pump flow was encountered. TEE images showed that the left atrial cannula was positioned against the left atrial wall. The cannula position was adjusted and the pump flow was established. During different stages of the surgery, TEE was used to monitor the left ventricular cavity size and its function. This allowed the adjustment of LAFB pump flow relative to left ventricular filling and optimal fluid resuscitation in order to maintain both upper and lower body perfusion.
In this patient, TEE was useful to confirm the correct position of the left atrial cannula and for hemodynamic management during LAFB.
描述经食管超声心动图（TEE）在一名接受胸腹主动脉瘤（TAA）手术并使用左心房-股动脉旁路（LAFB）的患者中的应用。
一名57岁女性患者接受了II型TAA修复术。按照机构常规，采用了LAFB技术。最初遇到了泵流量方面的困难。TEE图像显示左心房插管贴靠在左心房壁上。调整了插管位置并建立了泵流量。在手术的不同阶段，使用TEE监测左心室腔大小及其功能。这使得能够根据左心室充盈情况调整LAFB泵流量，并进行最佳液体复苏，以维持上半身和下半身的灌注。
在该患者中，TEE有助于确认左心房插管的正确位置，并在LAFB期间进行血流动力学管理。
