Abstract
Radiographic studies of bronchial contractions were performed after left lung autotransplantation in mongrel dogs. Methacholine chloride administered intravenously was used as a smooth muscle stimulus. The studies clearly showed the ability of the bronchi to contract. The nature of the bronchial blood supply was studied by means of in vivo arteriography and postmortem injection techniques. It was shown that blood from the aorta perfuses the bronchial wall via a bronchial arterial network in spite of the facts that this network was completely interrupted at the time of autotransplantation; and that no surgical attempt to anastomose the bronchial arteries was made. The authors conclude that, following left lung autotransplantation in the dog, there was a viable myoelastic bronchial network and that at some time within a year after the surgery, there was a spontaneous reconstitution of the bronchial arterial pathways supplying that network.
