摘要
对妊高征合并胎儿宫内发育迟缓（ＩＵＧＲ）１１例、ＩＵＧＲ１３例、正常妊娠分娩１５例患者的胎盘组织进行了形态测定及观察。结果表明：ＩＵＧＲ患者胎盘中代表胎儿循环的三级绒毛干动脉总数、正常动脉比例数及百分比明显低于对照组（Ｐ＜０．０１）。代表母儿交换能力的血管合体膜（ＶＳＭ）百分比及绒毛间隙容积百分比也明显低于对照组（Ｐ＜０．０５）。而标志着胎盘缺氧的合体结节绒毛百分比则显著增高。提示：有ＩＵＧＲ时胎儿循环阻力升高，灌流血量减少是影响胎儿发育的重要原因。
Objective:To study the histomorphometric changes in
patients who suffered from IUGR.Design:39 patients including 11 who
suffered from PIH with IUGR.Design:39 patients including 11 who
suffered from PIH with IUGR,13 with IUGR only and 15 normal pregnant
women were included in this study.Results:The results showed that the
total number of the stem arteries of the third degree villus and the
percentage of the normal arteries in IUGR were significantly lower
than that in normal pregnancy(P<0 01).The percentage of villus space
volume and vascular syncytial membranes(VSM)which represent the
ability of nutrient exchanging between mother and fetus in IUGR were
also lower than that in normal pregnancy(P<0.05).While the percentage
of syncytiotropholbast nodes was increased in IUGR,which resulted
from the anoxia of placenta.Conclusion:Our conclusion is that the
important causes that affect the fetal development in IUGR are the
higher resistance of blood circulation and the lower exchanging
ability. \ \
