Persistent Left Superior Vena Cava Detected with Radionuclide Angiocardiography

Abstract

A 28-yr-old man presented with paresthesias, fatigue, central cyanosis and erythrocytosis. A first pass flow study with 99mTc as free pertechnetate was done, among other tests, to exclude a central shunt when a persistent left superior vena cava was incidentally detected. The value of radionuclide angiocardiography to examine the central circulation noninvasively was again illustrated in this case.
