Journal Title: Indian Journal of Clinical Anatomy and Physiology - Year 2018, Vol 5, Issue 4
Abstract
Introduction Azygos system of veins comprising unpaired azygos vein and its main tributary the hemiazygos veins Variations have been observed in formation course of azygos vein also in its tributaries and anastomosesObjectives To observe azygos venous system patternMaterials 50 embalmed human cadavers irrespective of their sex and ageMethods Following Ansons classification system in which azygos venous system having vertical and horizontal connections which include three basic types primitive or embryological types transient type and single type as and their eleven subgroupsResults The basic type pattern in all the specimens 100 was transitional type In subgroups atypical type observed in 12 specimens 24 group 5 group 6B was observed in 11 specimens 22 group 2 was observed in five specimens 10 group 4 was observed in five specimens 10 group 7 was observed in 3 specimens 06 group 10 was observed in 03 specimens 06Conclusion The importances of variations in the pattern of azygos venous system which has to be identified during computed tomography and magnetic resonance imaging of mediastinum may be confused with aneurysm lymphadenopathy and other abnormalities like tumor During surgery of large vessel and the mediastinal operations these kinds of azygos venous system pattern variations have to keep in the mindKeywords Azygos vein Morphology Azygos venous system types
