Dilatation of the azygos-hemiazygos venous system presenting as paravertebral masses may be seen in intrahepatic and extrahepatic portal vein obstruction, anomalous pulmonary venous return, occlusion of the superior and inferior vena cava, persistence of the left superior vena cava, hepatic vein obstruction, elevation of central venous pressure as in congestive heart failure, pericardial effusi...

Although the most common form of the persistent left superior vena cava anomaly is usually clinically silent and often discovered incidentally, the risk of developing cyanosis, heart failure, and embolic cerebrovascular events is high among cases where the anomaly causes a right to left shunt. A rare case of persistent left superior vena cava draining into the left atrium through the superior l...

Options for cardiac device implantation in patients with central venous obstruction are limited. We describe a novel method of device implantation of an entirely endocardial biventricular defibrillator system using video thoracoscopy in a patient with superior vena cava obstruction. Direct right atrial access wasused for all leads andan endocardial left ventricular lead wasdeliveredvia atrial t...

Superior vena cava obstruction occurring as a complication of leiomyoma of the oesophagus has not been reported before. Such a case is recorded which was associated with striking eosinophilia, a feature previously noted in cases of uterine leiomyomas.

Obstructions of the upper venous system may be due to spontaneous thrombosis or the presence of hemodialysis or chemotherapy catheters, or even the presence of extrinsic compression due to intra-thoracic tumors. The use of endoprosthesis for the treatment of these obstructions has become common practice, and its indications include situations of risk for pulmonary embolism, superior vena cava s...

CONTEXT Venous thrombosis has been described in patients with acute and chronic pancreatitis. This is especially common in portal vein, splenic vein and superior mesenteric vein. To the best of our knowledge, involvement of superior vena cava and subclavian vessel due to pancreatitis has not been reported. CASE REPORT We present here a case of an adult male with alcoholic chronic pancreatitis...

RATIONALE Coronary artery fistula (CAF) is characterized by an abnormal communication of a coronary artery with a cardiac chamber or a great vessel bypassing the capillary bed. Surgical closure of large or symptomatic CAF is the gold standard treatment. However the previously closed CAF still has the possibility to reopen. Superior vena cava syndrome (SVCS) is defined as a condition that occurs...

the budd–chiari syndrome (bcs) is a rare disorder caused by the obstruction of the hepatic veins or the inferior vena cava (ivc) at the suprahepatic level. this syndrome is developed by either hepatic vein thrombosis or mechanical venous obstruction and leads to centrilobular hepatic congestion with the subsequent development of fibrosis and cirrhosis. intracardiac tumors have been rarely repor...

background: â budd-chiari syndrome (bcs) is a rare syndrome caused by hepatic venous outflow obstruction. the etiology of bcs differs between western and eastern countries. this article is a review of all published articles in iranian and international journals regarding different aspects of bcs (prevalence, etiology, and conventional treatments) in iran. materials and methods : â  in this revi...
