Abstract
In 39 pregnant and six nonpregnant dogs the abdominal aorta was exposed extraperitoneally
through a left paralumbar incision, and a vascular occluder and a flow transducer
were placed around it. The tubing of the occluder and the wiring of the flow transducer
were slipped under the skin and advanced to the back of the neck of the animal. Thus,
the aortic blood flow could be progressively reduced and continuously monitored. After
4 to 20 days of blood flow reduction of 35% to 75%, the picture of a moderately severe
toxemia appeared in 10 dogs and that of a mild toxemia was seen in the 11 others.
Nine animals were eliminated because of premature labor and three were eliminated
for surgical complications. The control group (six pregnant animals with a sham operation
and six nonpregnant animals with a severe aortic constriction) presented no abnormalities.
