[Subclavian arteriography in Pancoast syndrome. Case report (author's transl)].

A case of Pancoast's syndrome is reported, where subclavian arteriography was the only useful diagnostic procedure to make a diagnosis possible. Utilization and meaning of such a diagnostic technique is discussed, since the typical radiological picture of the syndrome may be lacking, especially in the early stage of the disease. Subclavian arteriography explores th costal-pleuro-vertebral space selectively, being aimed to one of the anatomical structure, the mechanical engagement of which is responsible of the syndrome. Such a technique is advisable even in cases where the Pancoast's syndrome is sustained by an infrequent aetiology, such as metastases.
