Duplication of the superior vena cava: detection by radionuclide angiography.
The authors report three cases of duplication of the superior vena cava which were demonstrated by radionuclide angiography. Nuclear imaging was performed in order to demonstrate a left-to-right intracardiac shunt. Injection into the left external jugular vein demonstrated the presence of a duplication of the superior vena cava in addition to the presence of a shunt.
