A reevaluation of placental grading and its clinical significance.

Abstract: Pregnancies complicated by preeclampsia or intrauterine growth retardation have an earlier and faster placental maturation than normal. This is demonstrated in a study of 1,096 obstetrical examinations of 473 non-diabetic mothers. It is recommended that a pregnancy demonstrating grade I maturational changes prior to 27 weeks, grade II changes prior to 32 weeks, or especially grade III changes prior to 34 weeks be followed clinically and ultrasonically for possible complications.

“…Birth asphyxia was observed more with grade III placenta in study group 9.3% compared to control group 3.2%. Hooper et al noted that if the placenta appeared to be grade I prior to 27 weeks, grade II prior to 32 weeks and grade III prior to 34 weeks of gestation, the pregnancy would be likely to be complicated with intrauterine growth retardation and pre-eclampsia [20]. This study is similar to our study.…”

“…This will serve as a baseline for normal characteristics in order to compare diseased states, most importantly placental insufficiency and placental invasion. The heterogeneity significantly changes later in pregnancy as already described by ultrasound [6,34] and therefore the MR finding of invasion or insufficiency must be made in this context.…”

“…The placenta becomes significantly more heterogeneous with fetal gestational aging, both through the maturation of the cotyledons and other processes associated with aging, such as fibrin accumulation and calcification [6]. The degree of placental maturity has historically been assessed by an ultrasound placental grading system (Grannum classification) [7].…”
