[Functional and morphological studies following bilateral combined bi-lobectomy with resection of th bronchus and pulmonary artery in an animal experiment].

The author carried out 91 combined bilobectomies with circular resection of the main bronchus and the pulmonary artery. The reconstruction was carried out by end-to-end anastomosis of the bronchus and autoplasty of the artery wall by means of different autografts. -- A two-phasic bilateral combined bilobectomy with resection of the bronchus and the pulmonary artery was carried out in two cases. These experiments were described. The functional and copensatoric possibilities of the remained lower parts of the lung regenerate in the late phase after the operation. The blood gas values and the acid-base balance are stabilized too. The structure of the operated lungs in the late phase after the operation is not different from the intact lung tissue. The bronchus anastomosis shows an epithelised mucosa with a soft collagen scar. The anastomosis of the pulmonary artery exhibits a little collagen scar with a swelling of the intima. The autograft was received by the vena azygos, it was structured as a vein with a well-preserved tunica muscularis. The Hering-Breuer-reflex was kept in all the time after the operation. A bilateral combined bilobectomy was not described hitherto in the bibliography.
