[Roentgeno-bronchological observations in experimental autotransplantation of the lung and its lobe].

Roentgenological studies were conducted after 260 autotransplantations of the lung and its lobe, performed experimentally and observed in dynamics during the period up to 4.5 years. Following autotransplantation of the lung in an uncomplicated postoperative period within the terms up to 15 days an intensified and indistinct pulmonary pattern with the presence of small-foci shadows is observed. Further observations for a period up to 4.5 years revealed neither changes on the part of pulmonary tissues nor anatomical or functional changes in the bronchial tree and vessels. In later terms after ortho- and heterotopic autotransplantation of the lower pulmonary lobe changes due to resection of the upper and cardiac lobe were observed, being manifested in displacement of a portion of the intact lung upper lobe into the upper portion of the left pleural cavity. Following heterotopic autotransplantation of the lower pulmonary lobe in the site of the removed lung no changes in the autotransplanted pulmonary lobe were noted in later periods. The signs of mediastinal hernia were less pronounced than after orthotopic autotransplantation of the pulmonary lobe.
