Anatomical variations of the azygos venous system
The azygos vein (gr. azygos – 'unpaired') typically starts from the posterior aspect of the inferior vena cava (IVC), at or below the level of the renal veins. The origin is not constant. If present, the lumbar azygos ascends anterior to the upper lumbar vertebrae. It may pass behind the right crus of the diaphragm or pierce it, or it may traverse the aortic hiatus to the right of the cisterna ...
متن کاملAnatomical Variations of the Azygos Venous System: Classification and Clinical Relevance
The azygos venous system is highly variable in terms of its origin, course, communications, tributaries and termination of the associated veins: this study aimed to classify these anatomical variations. Thirty Thiel-embalmed cadavers aged 48– 98 years (18 female, 12 male) were examined. The vertebral level of termination and diameter of the azygos, hemiazygos, accessory hemiazygos and the left ...
متن کاملAnatomical variations of coronary venous system and its tributaries: A cadaveric study
Method Total of fifty-five formalin-fixed adult human cadaveric hearts studied. Following measurements were noted: a.) length of coronary sinus, b). its relation to left coronary artery, mitral valve annulus and left atrium, c.) number of atrial and ventricular tributaries, d.) distance and the opening angles of major tributaries from the coronary ostium, e.) length and width of coronary ostium...
متن کاملPrenatal diagnosis of a variant of the azygos venous system
BACKGROUND The azygos venous system consists of the azygos vein on the right side and the hemiazygos and accessory hemiazygos on the left side. The azygos vein runs through the abdominal cavity along the right side of the vertebral bodies, in a cranial direction, passes through the diaphragm and reaches the mediastinum, where it forms the arch of the azygos which flows into the superior vena ca...
متن کاملLong saphenous vein and its anatomical variations
Vascular ultrasonography has an important role in the diagnosis and management of venous disease. The venous system, however, is more complex and variable compared to the arterial system due to its frequent anatomical variations. This often becomes quite challenging for sonographers. This paper discusses the anatomy of the long saphenous vein and its anatomical variations accompanied by sonogra...
