[The possibility of clinical diagnosis of non-massive pulmonary thromboembolism under conditions of limited availability of instrumental diagnostic tools].

The study included 105 patients with local segmental microcirculatory disturbances in the lungs and X-ray detectable pathologic changes of different localization or without them. The control group comprised 71 patients in whom perfusion scintiography revealed normal pulmonary circulation. Data on the patients' history, clinical and physical characteristics, results of laboratory analysis, functional-diagnostic, ultrasound and X-ray studies are presented. Discriminative analysis revealed significant differences between selected parameters that were used together with relevant canonical discrimination function coefficients to calculate "integral indices" characterizing clinical condition of individual patients. Their comparison in the affected and control patients allows to predict the probability of local segmental microcirculatory disturbances in the lungs and to enhance efficiency of diagnosis of non-massive thromboembolism of pulmonary artery.
