Learning objectives Recognize the key structures of the abdominal vasculature and its anatomical relations.Understand the causes of Abdominal Vascular Compression Syndromes (AVCS) and related clinical features.Comprehend computed tomography angiography (CTA) imaging patterns of AVCS. Recognize the complications associated to AVCS and its imaging patterns.
Read more Background We selected patients who were symptomatic, and had typical imaging findings of AVCS, including Median Arcuate Ligament Syndrome (MALS), Superior Mesenteric Artery Syndrome (SMAS), Anterior/Posterior Nutcracker Syndrome (A/PNCS), and May-Thurner Syndrome (MTS), were selected on our institution records. Literature search (English, and Portuguese) was also performed for discussion.
Read more Findings and procedure details Abdominal vascular compression syndromes designate the entrapment of blood vessels between surfaces in a restricted space, a phenomenon that may cause clinical manifestations, and be identified on imaging methods. Cross-sectional imaging with computed tomography (CT) is the imaging modality of choice to evaluate and diagnose these conditions. Their clinical manifestations are usually underestimated, mainly by their low prevalence, clinicians' low level of knowledge and symptoms unspecificity. When these entrapments become symptomatic, they result in a spectrum of syndromes, such as Median Arcuate...
Read more Conclusion Multiplanar and 3D volume-rendered reconstructions may be useful for eventual surgical planning. It is crucial to know the complications associated to the AVCS in order to early diagnose them.
