Contribution of angiopneumography to some problems of pulmonary physiopathology.

At the Eighth Panamerican Meeting of Tuberculosis (Mexico, 1949), it was said: “The comparative analysis of results obtained with both techniques, angiopneumography and bronchospirometry, is worthy of interest.” In a similar way, at the Third Interamerican Meeting of Radiology (Santiago, Chile, 1949) it was established, as proposed by one of us, that angiocardiography may well serve to study pulmonary and circulatory physiology and phisiopathology.2 Recently it has been said3 that “angiocardiography allows to appraise lung functional value through the study of intrapulmonary vascularization.” The present paper deals with 41 angiopneumographic studies made on 37 patients with different pathological lung conditions which, with some exceptions, were of tuberculosis origin. A comparative study between angiopneumography and broncospirometry has been made on 24 patients; in all of them appearance of the pulmonary circulation has been studied.
