The effect of lipiodol injected into the pulmonary artery on blood pressure in pulmonary artery and thoracic aorta in dogs.

The effect of lipiodol injected into the pulmonary artery on blood pressure in pulmonary artery and thoracic aorta in dogs. Acta Physiol. Pol. 1977, 28 (2): 143--151. The purpose of the experiments, carried out on 10 anaesthetized dogs, was to trace changes in pressure in aorta and pulmonary artery within 2 hours after injection of lipiodol Ultra-Fluide into the pulmonary artery of dogs. In individual experiments a gradual fall, rise or maintenance of normal pressure was found in the aorta. Pressure changes in the pulmonary artery were similar. Statistical analysis failed to demonstrate any significant correlation between the pressure in the aorta or in the pulmonary artery and the time of measurements of these pressures during the two-hour experiment.
