ABSTRACT: <\/strong><\/p>\n

Background<\/strong>: The azygos venous system represents an accessory venous pathway supplying an important collateral circulation between the superior and inferior vena cava. The azygos vein is a collateral venous pathway, becoming a vital shunt if major pathways of venous return are obstructed.<\/p>\n

Material and Methods<\/strong>: A total of 36 cadavers and dissected specimens were studied. A thorough dissection of the mediastinum was done after the removal of heart and the lungs. The shape, level of termination, dimensions and course & relations of arch of azygos vein was noted on the right side. The diameter of the inferior vena cava was also measured.<\/p>\n

Observations and Results: <\/strong>most commonly the arch forms an inverted U shaped course. 89% of the case the azygos vein was opening into extra-pericardial part of superior vena cava at a mean distance of 42.5mm from the formation In 19 (53%) cases out of 36 it was opening into superior vena cava at the level of T4. Next commonest level of opening (14%) was at the junction of T3-T4. length varied from 28 to 48 mm. The mean width of IVC was 18 mm +\/- 3.5mm. It was observed that the diameter of IVC is inversely proportional to width of azyos vein.<\/p>\n

Conclusion: <\/strong>In the present study the normal variations of the morphometry of azygos vein is noted. It is clear that the diameter of SVC is inversely proportional to that of Azygos vein.<\/p>\n

Key wods: <\/strong>Arch, Azyos vein, Inferior Vena Cava, Superior Vena Cava.<\/p>\n
