Celiac artery compression: Dunbar syndrome

Abstract Celiac artery compression syndrome, also referred to as median arcuate ligament syndrome, celiac axis syndrome or Dunbar syndrome is a rare disorder consequent to extrinsic compression of the celiac trunk by the median arcuate ligament. Doppler ultrasound, multi-slice computed tomography angiography, magnetic resonance angiography, or invasive selective angiography can identify stenosis of the initial segment of the celiac artery and confirm diagnosis. Treatment options include open surgical or videolaparoscopic section of the median arcuate ligament and the fibers of the celiac plexus, or percutaneous transluminal angioplasty via an endovascular approach. We report herein an interesting case of a 38-year-old woman diagnosed with this rare condition and successfully treated with the surgical strategy.

摘要 腹腔动脉压迫综合征（Celiac artery compression syndrome），又称正中弓状韧带综合征（median arcuate ligament syndrome）、腹腔干综合征（celiac axis syndrome）或邓巴综合征（Dunbar syndrome），是一类由正中弓状韧带外源性压迫腹腔干所引发的罕见疾病。多普勒超声（Doppler ultrasound）、多层计算机断层血管造影（multi-slice computed tomography angiography）、磁共振血管造影（magnetic resonance angiography）或有创选择性血管造影可检出腹腔动脉起始段狭窄，进而明确该病症的诊断。治疗方案包括开放手术或腹腔镜下正中弓状韧带及腹腔神经丛纤维切断术，亦或经血管内入路行经皮腔内血管成形术。本文报告1例38岁女性患者确诊该罕见病症，并经手术方案成功治愈的典型病例。
