The results of 59 embolizations of the bronchial and intercostal-bronchial arteries in 33 patients with pulmonary hemorrhage and hemoptysis allow hydrogel emboli to be considered the optimal material for occluding vessels to achieve stable hemostasis. Successive introduction of spherical and then larger cylindrical emboli is the most rational method. Embolization of the bronchial arteries by hydrogel emboli also promotes regression of the inflammatory process in the lung and reduces the time needed for treatment.
