Open full text 5 citations

Abstract

The azygos vein (AV) system is considered a venous system which displays great variability in its formation and course. Especially, regarding the origin of the AV system, the international literature describes mostly the union of the ascending lumbar with the subcostal veins, though other origins are documented as well. The current study displays an abnormal origin of the azygos system, which to the best of our knowledge has never been described before.
