BACKGROUND/AIM: Compression of celiac artery by median arcuate ligament (MAL) may cause abdominal symptoms. This study looked at the prevalence of this finding in asymptomatic persons.
Abdominal angiograms of 155 healthy asymptomatic voluntary kidney donors aged 18-65 years, done as part of the standard pretransplant work up, were reviewed retrospectively.
Celiac axis compression, defined as greater than 50% luminal narrowing of the celiac artery by the MAL was found in eight (5.1%) of 155 angiograms.
The high frequency of this finding re-emphasizes the need for caution in attributing abdominal symptoms to such compression based on imaging findings alone.
背景/目的：正中弓状韧带（MAL）对腹腔干的压迫可能导致腹部症状。本研究观察了无症状人群中这一发现的发生率。
回顾性分析了155例年龄在18 - 65岁的健康无症状自愿肾脏捐献者的腹部血管造影图像，这些图像是标准移植前检查的一部分。
在155例血管造影图像中，有8例（5.1%）发现腹腔干轴受压，定义为MAL导致腹腔干管腔狭窄超过50%。
这一发现的高频率再次强调了仅基于影像学发现将腹部症状归因于此类压迫时需谨慎的必要性。
