Venous Anatomy Chest

Although plain film radiography was once considered the gold standard for chest evaluation both multidetector computed tomography and magnetic resonance imaging are becoming indispensable for delineation of the different drainage patterns of the thoracic venous system. The normal anatomy of the azygos and hemiazygos systems is described in heitzmans excellent text on the mediastinum basically both systems are thoracic continuations of the ascending lumbar veins and provide venous drainage for intercostal and paravertebral veins within the posterior aspect of the thorax.

Venous anatomy chest. The carina is clearly visible on most chest x rays and so is used as a landmark to help determine central venous catheter cvc location correct positioning of a cvc tip depends on the side of entry correct positioning of a cvc tip also depends on the intended use of the catheter. Venous catheters placed caudad to this landmark and cephalad to the right superior cardiac silhouette or no more than 29 cm caudad to the tracheobronchial angle result in catheter tips within the svc. Venous anomalies of the thorax are frequently shown on imaging studies.

In general the veins preferred for placement of central and peripheral venous access catheters are the internal jugular veins in the neck the axillary and subclavian veins in the chest the cephalic and basilic veins in the upper extremities and the superficial femoral and common femoral veins in the lower extremities. As the heart pumps inside the center of the chest. In some cases the diagnosis is based on a chest radiograph when a radiopaque iv catheter takes an unusual but distinctive course such as a catheter in a left svc.

Venous anatomy or variations thereof can also be crucial to surgical colleagues for operative planning and follow up. The chest is the major hub of the circulatory system it houses the heart lungs and other major organs that need large amounts of blood flow. Venous anatomy or variations thereof can also be crucial to surgical colleagues for operative planning and follow up.

Clinical implications this article provides a practical approach to the clinical implications and importance of understanding the collateral venous anatomy of the thorax.
