Perinatal outcome and near miss morbidity between placenta previa versus abruptio placentae.
Compared with women without EDS, those with the inherited connective tissue disorder had adjusted odds ratios (AORs) of 3.2 for cervical incompetence (95% confidence interval, 2.0-5.1) and 2.2 for placenta previa (95% CI, 1.3-3.9; P less than .01 for both).
However, Hershkowitz and colleagues found no association between many cesarean deliveries and placenta previa. [6] We cannot comment on the relative effects of parity, a known risk factor for placenta previa, because our cohort included only cesarean deliveries, as opposed to all deliveries.
In examining current surgical practice and literature, we found that the most common complications of repeat CSs are placenta previa, uterine dehiscence or rupture, and vascular and adjacent organ injuries.
More simply, elective CS, compared with emergent CS, 'scars the uterus much more.' Pregnant women with prior labor (−) CS, compared with those with prior labor (+) CS, were more likely to have placenta previa [3] and also thinner lower uterine segment [4] in the subsequent pregnancy.
Placenta previa in the setting of prior CD carries the highest risk of PAS--as high as 61% in women with both placenta previa and a history of 3 CDs.
In fact, the frequency of EPH after vaginal delivery ranges from 0.1 to 0.3 per 1000 deliveries, but in previous CS patients, the frequency of EPH icreases to 1.1 to 8.9 per 1000.6,7 A higher the number of previous CS means a higher abnormal placentation.2 In addition, our study showed that the most common indication of EPH was abnormal placentation with placenta previa (70.9%).
Previous CS (one or more) had been performed in 69 women (87%), 71 (93%) had placenta previa associated or not with placenta accreta.
A more informative comparison would be to compare PAS specimens and those taken from placenta previa with no evidence of adherence taken from women with a scarred uterus.
Several risk factors have been identified for the development of placenta accreta, including previous cesarean delivery, advanced maternal age, high gravidity, multiparity, previous uterine curettage, and placenta previa [3].
She gave a history of having undergone a caesarean section in June 2016 for placenta previa. Her postoperative period was uneventful and she passed lochia normally.
Battledore insertion of the umbilical cord is though reported to have little clinical significance by some studies (6, 7), others have reported increased incidence of placenta previa, abruptio placentae, preeclampsia, preterm delivery, increased incidence of emergency LSCS and poor neonatal outcome (8, 9).
Speaking in the Sunday Independent's Life magazine, Miriam said: "My consultant said they would write an obstretrics book about me because I'd it all - pre-eclampsia, placenta previa, twins, forceps, suction.
Regarding obstetrical complications 3(6%) patients had placenta previa, 3(6%) had placental abruption, 7(14%) had mal presentation, 3(6%) had obstructed labor and 34(68%) didn't had complications.
These might include maternal age <20 or >35 years old, ([4]) parity >3, ([5]) employed, ([6]) antenatal care <4 visits, ([7]) birth spacing >2 years, ([5]) and maternal morbidity (anemia, preeclampsia, and placenta previa).
