“…They show an increase of 30% in renal blood flow and glomerular filtration during pregnancy [1,4]. SOHN and FENDEL have found a decrease in the RI in both main renal and uterine arteries in late pregnancy (35 to 38) weeks [4].…”

The Resistance Index (RI) was studied in the main renal arteries in normal nonpregnant women and its change during normal pregnancy. One hundred and seventy color and pulse Doppler sonographic examinations were performed on 31 nonpregnant and 54 pregnant women. The range of gestation was 5-39 weeks, and patients divided into three groups; 5-12, 13-25 and 26-39 weeks of pregnancy, respectively. The RI was calculated in both main renal arteries. In nonpregnant women the left main renal artery RI mean = 0.587 +/- 0.021, and the right main renal artery RI mean = 0.584 +/- 0.028. In pregnant women the left main renal artery RI mean was 0.681 +/- 0.029, and the right main renal artery RI mean was 0.697 +/- 0.034. There was a significant difference between the main renal artery RI in pregnant and nonpregnant women (P less than 0.01). There was no significant difference between left and right main renal artery in pregnant and nonpregnant women (P less than 0.01). There was no correlation between gestational age and RI in the right main renal artery but a statistically significant correlation with gestational age in the left main renal artery (P less than 0.05).

Clinical studies showed a lower blood flow in renal und uterine vessels in gestotic pregnancies. A comparison was therefore made between three maternal vessels (uterine, renal und thyroideal vessels) in normal and gestotic pregnant and non-pregnant women to show if the higher vessel resistance in gestotic pregnancies is a local or systemic event. There was a significant difference between the collectives in the blood flow of renal and uterine vessels, but no difference between the resistance in thyroideal vessels. The difference in the blood flow of renal vessels was higher than the difference in uterine vessels in the pregnant women. The increasing resistance, therefore, seems to be a local event at the beginning of the gestotic pattern of signs and symptoms. The higher resistance in the renal vessels allows, the conclusion that the kidney might be the important organ in the origin of the gestotic pattern of signs and symptoms.

“…That placental antibodies might be a cause of preeclampsia was first suggested by Seegal and Loeb.' 9 Hypertension was produced in pregnant rats by injection of antiplacental serum. 12 The presence of circulating antibodies to the placental antigens in patients with toxemia was reported."…”
