[Value of superior vena cava angiography in Schwartz-Bartter syndrome (author's transl)]. / Intérêt de l'angiographie cave supérieure dans le syndrome de Schwartz-Bartter.

Schwartz-Bartter syndrome often results from lung cancer. With reference to two observations, attention is drawn to the value of opacifying the superior vena cava for demonstrating the tumor. This investigation also allows guided biopsy sampling as exemplified in the second observation. Vascular investigations seem all the more useful as small-cell carcinoma often develops outside the bronchi and are often inaccessible by endoscopy.
