[Pulsed Doppler in the diagnosis of obstruction of the superior vena cava. Apropos of a case]. / Doppler pulsado en el diagnóstico de obstrucción de vena cava superior. A propósito de un caso.

We report the case of a patient diagnosed as superior vena cava syndrome 8 years after surgical resection of a breast malignancy and treatment with radiotherapy. The study with pulsed Eco-Doppler detected the presence of obstruction to the systemic venous return, allowing us to establish the diagnosis. Confirmation was achieved by means of venography and venous pressure manometry. Usefulness of the Doppler technique in the assessment of systemic venous return is confirmed.
