Sma And Smv Relationship - Web inversion of the sma/smv relationship so the sma lies on the right and the smv on the left. Citation, doi, disclosures and article data. Web for example, deviation from the normal relationship between the superior mesenteric artery (sma) and superior mesenteric vein (smv) is a useful indicator of malrotation. The superior mesenteric vein (smv) should be positioned to the right of the sma, especially the first 3 cm distal to its origin. Smv (v) is located to left of axis. Note however that this inverted relationship is seen in up to 11%.
