BACKGROUND
The median arcuate ligament passes superior to the origin of the celiac artery and is a continuation of the posterior diaphragm that wraps over the aorta. If it lies too low on the aorta, the ligament may cause symptoms of abdominal pain related to compression of the celiac artery.
CASE REPORT
An abdominal ultrasound in a 22-year-old woman with longstanding abdominal pain after eating showed elevated celiac artery velocities of >300 cm/s upon inspiration. Computed tomography angiography of the abdomen showed stenosis of the origin of the celiac artery and confirmed the diagnosis of median arcuate ligament syndrome. Laparoscopic release of the median arcuate ligament resulted in relief of the patient's symptoms.
CONCLUSION
The diagnosis of median arcuate ligament syndrome should be considered in patients with postprandial abdominal pain that does not have a clearly established etiology.
背景
正中弓状韧带位于腹腔干动脉起始部的上方，是后纵隔的延续，包绕在主动脉上方。如果该韧带在主动脉上位置过低，可能会导致与腹腔干动脉受压相关的腹痛症状。
病例报告
一名22岁女性，进食后长期腹痛，腹部超声显示吸气时腹腔干动脉流速升高>300 cm/s。腹部计算机断层血管造影显示腹腔干动脉起始部狭窄，确诊为正中弓状韧带综合征。腹腔镜下松解正中弓状韧带后患者症状缓解。
结论
对于餐后腹痛且病因不明的患者，应考虑正中弓状韧带综合征的诊断。
