Deployment of stent-grafts and other endovascular devices is a common technique for various vascular repair procedures. Induced, transient, periods of hypotension are essential to the precise deployment of a device as this minimizes displacement that can result from high pressure aortic flow. Partial inflow occlusion of the right atrium is a reliable, precise, and safe method of achieving this. We present a case where intraoperative transesophageal echocardiography (TEE) was used to guide and confirm balloon placement for right atrium inflow occlusion during a thoracic endovascular aneurysm repair (TEVAR) procedure for repair of an aortic dissection in a 67 year old male. This highlights a novel use of TEE in the context of endovascular surgery, and showcases an alternative method of reliably achieving transient hypotension.
部署支架移植物和其他血管内装置是各种血管修复手术的常用技术。诱导性短暂低血压期对于精确部署装置至关重要，因为这可将高压主动脉血流导致的移位降至最低。右心房部分流入道闭塞是实现这一目标的可靠、精确且安全的方法。我们报告一例在一名67岁男性主动脉夹层修复的胸主动脉腔内修复术（TEVAR）中，术中经食管超声心动图（TEE）用于指导和确认右心房流入道闭塞球囊放置的病例。这突出了TEE在血管内手术中的一种新用途，并展示了可靠实现短暂低血压的另一种方法。
