Veins in the thoracic cavity are highly variable in terms of their communications. Thirty Thiel-embalmed cadavers were dissected (18 females and 12 males), ranging in age from 48 to 98 years old (mean 81.3±12.40). The lungs, heart, thoracic aorta, oesophagus and parietal pleura were removed carefully to expose the azygos, hemiazygos, accessory hemiazygos veins and thoracic duct. In most specimens (21) intervertebral veins were connected directly to the azygos venous systems rather than the proximal end of the posterior intercostal veins. This presentation was observed to be more common on the right side, but not at all vertebral levels. These communications could play a role in regulating blood volume between the azygos and vertebral venous systems; they may also act as metastatic pathways between the thoracic and abdominal regions. As they mimic posterior intercostal vessels, it is important for surgeons to be aware of this variation to avoid injuries leading to postoperative hematomas.
