Anomalies of the venous system are known to be varied and frequent and, therefore, are often taken for granted. Perhaps for that reason we have been unable to discover in the literature an adequate description of a single midline vein receiving the drainage usually cared for by the azygos and hemiazygos systems. The condition has been observed previously, for in Piersol's Human Anatomy (1936, p...
BACKGROUND Chest X-ray is routinely performed to check the position of the central venous catheter (CVC) inserted through the internal jugular or subclavian vein, while the further evaluation of CVC malfunction is usually performed by contrast venography. In patients with superior vena cava obstruction, the tip of the catheter is often seen in collateral mediastinal venous pathways, rather than...
Background and Aim: Heart failure (H.F) is a burgeoning prevalent problem worldwide, which has involved over 20 million people. Echocardiography is the best standard process in diagnosing H.F. Thus, it is one of the first measures which should be taken for patients referring to the emergency ward. In the present study, the rate of chest X-ray diagnostic accuracy with respect to the occurrence o...
An azygos vein aneurysm is a very rare cause of a posterior mediastinal mass. Once the diagnosis has been confirmed, no treatment is usually required. However, the aneurysm can thrombose, and this may lead pulmonary thromboembolism, or the aneurysm may rupture. In these instances, the excision of the mass is recommended. Video-assisted thoracic surgery techniques have considerably improved. If ...
Inferior vena cava (IVC) hypoplasia is a rare condition. Venous blood flow is usually provided through collaterals in the azygos or hemiazygos venous systems. However, portosystemic shunts with intrahepatic venous collateral are extremely rare. The case is presented here of a large shunt between the right hepatic vein, accessory inferior hepatic vein, and inferior vena cava in a 37-year-old fem...
