Celiac artery compression: Dunbar syndrome / Síndrome da compressão da artéria celíaca (síndrome de Dunbar)

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

A síndrome da compressão da artéria celíaca, também denominada síndrome do ligamento arqueado mediano, síndrome do eixo celíaco ou síndrome de Dunbar, é uma doença rara causada pela compressão extrínseca do tronco celíaco pelo ligamento arqueado mediano. Ultrassonografia Doppler, angiotomografia computadorizada, angiorressonância magnética ou angiografia seletiva invasiva conseguem identificar a estenose do segmento inicial da artéria celíaca e confirmar o diagnóstico. As opções de tratamento incluem secção videolaparoscópica ou laparotômica (a céu aberto) do ligamento arqueado mediano e das fibras do plexo celíaco, assim como angioplastia transluminal percutânea. Relatamos o interessante caso de uma mulher de 38 anos de idade diagnosticada com essa rara condição e adequadamente tratada pela estratégia cirúrgica

Median Arcuate Ligament Syndrome in a Pediatric Patient: A Rare Case Report.

The median arcuate ligament (MAL) syndrome is an infrequently described condition caused by compression of the celiac artery by the extended fibers of the MAL resulting in the classic triad of postprandial epigastric pain, nausea/vomiting, and weight loss. Mostly seen in young female adults there is no reported estimate in the pediatric age group. We report the case in a 15-year-old girl and discuss the surgical aspects of importance.
