ResumoSelective pulmonary phlebography before and after infusion of serotonin has graphically demonstrated active in vivo pulmonary venomotion for the first time. The evidence of venous constriction was of two types: (1) decreased retrograde pulmonary venous, capillary, and arterial filling, and (2) distinct changes in the caliber of the veins, with kinking and narrowing. These findings add further weight to the accumulating evidence of other types which indicates that the pulmonary veins are not merely passive channels, but serve an important hemodynamic function.
