The value of radionuclide venography in superior vena caval obstruction. 1985

R S Coltart, and E P Wraight

A prospective study on 27 patients with suspected obstruction of the superior vena cava (SVC) and 10 control patients with no known chest disease was undertaken to determine the value of radionuclide venography in aiding diagnosis and treatment of the condition. The technique proved simple, safe and non-invasive and could rapidly confirm or exclude the diagnosis when in doubt. In addition, the technique had a role in radiotherapy planning, highlighting unsuspected superior mediastinal disease not visible on the chest radiograph. However, follow-up post-treatment scans were of little help due to the good clinical markers of obstruction of the SVC. The normal and abnormal scan appearances are described.

D011446	Prospective Studies	Observation of a population for a sufficient number of persons over a sufficient number of years to generate incidence or mortality rates subsequent to the selection of the study group.	Prospective Study,Studies, Prospective,Study, Prospective
D011877	Radionuclide Imaging	The production of an image obtained by cameras that detect the radioactive emissions of an injected radionuclide as it has distributed differentially throughout tissues in the body. The image obtained from a moving detector is called a scan, while the image obtained from a stationary camera device is called a scintiphotograph.

D013479	Superior Vena Cava Syndrome	A condition that occurs when the obstruction of the thin-walled SUPERIOR VENA CAVA interrupts blood flow from the head, upper extremities, and thorax to the RIGHT ATRIUM. Obstruction can be caused by NEOPLASMS; THROMBOSIS; ANEURYSM; or external compression. The syndrome is characterized by swelling and/or CYANOSIS of the face, neck, and upper arms which is called Pemberton's sign. Classification of SVC obstruction is often based on COLLATERAL CIRCULATION.
