Abstract

يعتبر نقص التروية المشيمية من الأسباب المهمة لنقص النمو داخل الرحم, ممّا يؤدي لولادة أجنة ناقصة النمو ولموت الأجنة.

يمكن تقييم التروية المشيمية عن طريق دراسة مشعر مقاومة الجريان الدموي في الشريان السري.

شملت الدراسة 187سيدة حاملاً بأجنة دون علامات لنقص نمو داخل الرحم, بإجراء قياس مشعر المقاومة في الشريان السري وتسجيل النتائج لتحديد القيم الطبيعية.

تراوح عمر الحمل في الحالات المدروسة من 20إلى 40 أسبوعاً.

ساعدت القياسات على وضع مخطط بياني يظهر متوسط قيم مشعر المقاومة وتغيراته في كل أسبوع حملي

أظهرت الدراسة مشعر مقاومة مع قيمة وسطية 0,76 في الأسبوع العشرين للحمل و0,56 في الأسبوع الأربعين مع هبوط متدرج بتقدم عمر الحمل .

Placental circulation deficiency is considered one of the main reasons of growth of deficiency inside the uterus, leading to the birth of an underweight or dead fetus. Placental blood flow maybe evaluated through the study of the resistance index of the flow in umbilical artery.

The study has covered (187) pregnant women with embryos, having no signs of growth of deficiency inside the uterus by measuring the resistance index of umbilical artery and listing the results to confirm the natural values.                                      The period of pregnancy in the studied cases has covered the time from 20 to 40 weeks. These values have helped to present a graph that shows the average values of resistance index and its changes through every week of pregnancy.

The study has shown an average resistance index value of (0,76) in the (20th) week of pregnancy and of (0,56) in the (40th) week with down-word values as the pregnancy period increases.
