Hepatic changes have been studied in 25 pupies with modeled stenosis with compensation and 8 animals with decompensated stenosis of pulmonary trunk. For controlling we have used liver of 10 dogs of the same age. Material has been tested by hystological, morfometric and stereometric mesurements. We have figured that after pulmanory trunk stenosis and the decrease in circulation of hepatic venous blood tonus of arteries increases, reflectory and resistance to circulation grows. Except venous-arterial reactions in incoming vessels small boundles of oblique intimal muscular system, muscular-elastic sfincters, polipsimillar pillows have been formed and in outcoming vessels muscular structures hypertrophy.has been indicated In case decompensated stenosis with hypoxia relaxation of outcoming and outgoing vessels happens, the quantity of arteries with adapting structures decreases, and muscular formations of hepatic veins atrophy.
