[Scintigraphy in tuberculosis patients with concomitant nonspecific infection].

The data of clinical, X-ray, and radioisotopic pulmonary scintigraphic studies were analyzed in 119 patients with tuberculosis. In patients with pulmonary tuberculosis concurrent with nonspecific infection, impaired pulmonary capillary blood flow may occur in the area of lesion in 60.8% of cases. Concomitant chronic bronchitis observed in half of the patients of this group is an important pathogenetic point of this unfavorable tendency resulting in increased fibrosis in the lung. Less effective treatment of the underlying diseases is another factor contributing to a reduction in pulmonary capillaries during therapy.
