Urgency of diagnostics and treatment of acute purulent abscesses of lungs issue is determined by prevalence and severity of this pathology. Acute purulent abscesses of lungs (APAL) are a part of diseases usually called purulo-destructive diseases of lungs (PDDL). Gangrenous abscess, pulmonary gangrene and pleural empyema are also included into this group.

    In our country number of patients with abscesses, pulmonary gangrene and pleural empyema has upward tendency. It is the result of late diagnostics and hospitalization, inadequate therapy of pneumonia.

    In spite of treatment methods improvement, mortality at PDDL remains rather high and may reach 70%. In more that one third of patients transition from acute process to chronic is registered. Lethality at acute abscesses of lungs ranges from 7.2% to 28.3%; at gangrenous processes – from 23.4% to 74.1%.

    Due to this fact well-timed and accurate diagnostics of disease gains significant practical importance; results of such diagnostics are the basis of patients treatment tactics choosing. NLS-research by metatron 4025 hunter is one kind of the diagnostics for this.
