Dunbar syndrome is caused by the compression of the celiac artery by the median arcuate ligament (MAL) and the diaphragmatic crura, presenting with abdominal pain. The treatment is surgical, with the aim of dissecting and separating the diaphragmatic crura from the celiac axis, restoring blood flow in the celiac trunk. We propose the use of transesophageal echocardiography to measure the peak systolic velocity in the celiac trunk and to evaluate, in real time, the efficacy of the surgery during MAL resection. Two clinical cases with practical implications are reported. In one of these, the ultrasound exam was useful in providing an intraoperative confirmation of the outcome of the resection.
