Varices of inferior epigastric veins caused by chronic inferior vena cava obstruction: mimicking normal venous flow pattern on radionuclide venography.
نویسندگان
چکیده
A 21-year-old patient with long-standing inferior vena cava obstruction secondary to idiopathic thrombosis extending from the external iliac veins underwent a radionuclide venography with Tc-99m pertechnetate labeled erythrocytes. The blood pool phase of the study revealed bilaterally distorted inferior epigastric veins mimicking normal venous flow pattern. The authors present this case to discuss the possible alternative routes and the underlying physiopathologic mechanism of this unusual flow pattern in chronic inferior vena cava obstruction.

Background: The clinical presentation of non-Hodgkin lymphoma (NHL) varies tremendously depending upon the type of lymphoma and the areas of involvement. NHL can rarely present as an abdominal mass compressing the inferior vena cava. The clinical presentation due to obstruction of inferior vena cava has often been called the inferior vena cava syndrome (IVCS). It can present acutely or chronica...

PURPOSE The accurate diagnosis of deep vein thrombosis (DVT) is essential to prevent its complications and to initiate appropriate treatment. Doppler ultrasound (DUS), contrast venography, and intravenous radionuclide venography have been used for many years to detect DVT. However, obtaining venous access in the foot for injection of contrast agent can be difficult. METHODS The authors introd...

Discussion Although anomalies of the inferior vena cava are commonly discovered during imaging for other diseases,'-3 it seems that the anomaly in this patient directly contributed to the pathogenesis of the haemoptysis. The bronchial venous system communicates freely with the pulmonary veins and alveolar capillaries on one side, and with the azygos vein on the other." A direct communication be...

Essential thrombocythemia is a chronic myeloproliferative disorder characterized by a sustained proliferation of megakaryocytes, which leads to increased numbers of circulating platelets. Hemorrhagic and/or thrombotic episodes are frequent, and thrombosis of both veins and arteries may develop. Vessels in unusual sites may be involved, e.g., the hepatic veins, mesenteric veins, and the dig...
متن کاملDynamic Radionuclide Venogram Correlation with Radiographic Contrast Venography
A simple technique of dynamic radionuclide venographyusing a Searle LFOV gamma camera and an associated whole-body scanning couch-was investigated to demonstrate venous flow from the foot to the inferior vena cava on a single image. Results of this method were correlated with radiographic contrast venography in prospective studies in 84 patients. Correlation between radionuclide and contrast ve...
