The diagnosis of transcapillary flow disturbances in the lungs of lung cancer.

We have made the diagnosis of transcapillary flow disturbances in the lungs of lung cancer patients with the available noninvasive method of videobiomicroscopy of eye conjunctiva with further morphometric processing of obtained data using PC. 77 patients with lung cancer have been studied. Using videobiomicroscopy we calculated the size of venous capillary sacculations, the square of capillary glomerules (Sg), the amplitude (A), the 'length' of the twisted part of a microvessel (Lt), the amplitude-length coefficient (Ca), the frequency-length coefficient (Cf), the size of venous capillaries (V), intravascular conglomeration of aggregated erythrocytes (conglomerate), RBC aggregation coefficient (Cs) and the degree of sludge. To evaluate the data obtained, a comparative morphologic investigation of histologic samples taken from the intact areas of the lung parenchyma has been carried out. We diagnosed moderate or determined disturbances in the capillary flow that were confirmed by microscopy.
