Median arcuate ligament syndrome (MALS) can be a debilitating condition resulting in epigastric pain, nausea, difficulty eating due to postprandial pain, weight loss, and malnutrition in otherwise healthy individuals. The pain is caused by the compression of the celiac artery and neural ganglia by the median arcuate ligament as it attaches from the spine to the diaphragm. Diagnostic imaging, either duplex or angiography, can show the abnormality however, vague symptoms can lead to a missed diagnosis. While MALS is a known anatomical variation in the population, to our knowledge, has not been identified to be caused by trauma. Here, we present 4 patients who developed MALS following abdominal or spinal trauma whom all required surgery to alleviate lifestyle-limiting pain.
中位弓状韧带综合征（MALS）可能导致严重的疾病，使健康个体出现上腹痛、恶心、餐后疼痛导致进食困难、体重减轻和营养不良。疼痛是由中位弓状韧带从脊柱附着到横膈膜时压迫腹腔动脉和神经节引起的。诊断成像（无论是双功能超声还是血管造影）都可以显示异常，但是模糊的症状可能导致误诊。虽然 MALS 是人群中已知的解剖变异，但据我们所知，它不是由创伤引起的。在这里，我们介绍了 4 例在腹部或脊柱创伤后发生 MALS 的患者，他们都需要手术来缓解限制生活的疼痛。
