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 anastomoses.
Objectives: To observe azygos venous system pattern.
Materials: 50 embalmed human cadavers irrespective of their sex and age.
Methods: Following Anson’s 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 subgroups.
Results: 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 (06%).
Conclusion: The importance’s 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 mind.

Keywords: Azygos vein, Morphology, Azygos venous system types.
