| Popis | Learning objectives The objectives were to explain anatomical background of celiac artery compression syndrome, to learn how to assess the imaging modalities used in the diagnosis of this syndrome, and to discuss significance for endovascular interventions and potential clinical manifestation. Background The celiac artery compression is not uncommon entity. With extensive use of CT angiography it could be seen in significant group of patients and it could also be found in up to one-third of autopsy studies, but only few patients manifest typical clinical signs represented usually by postprandial pain and weight loss and definitive pathophysiological mechanism is still unclear. Clinical Findings/Procedure Celiac artery compression is caused by fibers of median arcuate ligament connecting diaphragmatic crura. It could be visualized with conventional or CT (poss. MR) angiography. The lateral (sagittal) view is crucial and the compression has a typical focal hooked appearance narrowing of the proximal celiac artery. This narrowing could be highly influenced by respiratory movements and it typically increases during expiration. In groups of symptomatic patients the surgical therapy could be considered, but the indication criteria remains controversial. Conclusion Although celiac artery compression is not uncommon entity and could be found in significant number of CT angiography studies, majority of patients has no symptoms and findings must be correlated with clinical signs. Besides potential clinical symptoms it could be source of difficulties for endovascular procedures involving catheterization of celiac artery and thus the basic knowledge of this entity could prevent potential complications. |
