PARTIAL OCCLUSION OF THE PULMONARY AORTA AND INFERIOR VENA CAVA WITH THE METALLIC BAND. OBSERVATIONS ON CHANGES IN THE VESSEL WALL AND IN THE HEART.
In dogs a constricting metallic band does not affect the integrity of the wall of the vena cava, whereas it leads to a rapid death of the wall of the aorta, and, as evidenced by a single instance studied, to a much slower death of the pulmonary artery. In the instance, just mentioned, constriction of the common pulmonary artery by an aluminum band for a period of 2(1/2) years led to a right ventricular hypertrophy.
