The following have been identified as risk factors for placenta previa: Previous placenta previa (recurrence rate 4–8%), [13] caesarean delivery, [14] myomectomy [10] or endometrium damage caused by D&C. [13] Women who are younger than 20 are at higher risk and women older than 35 are at increasing risk as they get older.
VBAC, compared to vaginal birth without a history of Caesarean section, confers an increased risks for placenta previa, placenta accreta, prolonged labor, antepartum hemorrhage, uterine rupture, preterm birth, low birth weight, and stillbirth. However, some risks may be due to confounding factors related to the indication for the first ...
An important risk factor for placenta accreta is placenta previa in the presence of a uterine scar. Placenta previa is an independent risk factor for placenta accreta. Additional reported risk factors for placenta accreta include maternal age and multiparity, other prior uterine surgery, prior uterine curettage, uterine irradiation, endometrial ablation, Asherman syndrome, uterine leiomyomata ...
Placenta praevia refers to when the placenta of a growing foetus is attached abnormally low within the uterus. Intermittent antepartum haemorrhaging occurs in 72% of women living with placenta praevia. [6] The severity of a patient's placenta praevia depends on the location of placental attachment;
Green Armytage forceps are specifically designed for this purpose. [3] Although the incision is made using a sharp scalpel, care must be taken not to injure the foetus, especially if the membranes are ruptured, or in emergencies like abruption. The incision can be extended to either sides using scissors or by blunt dissection using hands.
Reasons for the operation include obstructed labor, twin pregnancy, high blood pressure in the mother, breech birth, shoulder presentation, and problems with the placenta or umbilical cord. [ 2 ] [ 3 ] A caesarean delivery may be performed based upon the shape of the mother's pelvis or history of a previous C-section.
Along with placenta previa and uterine rupture it is one of the most common causes of vaginal bleeding in the later part of pregnancy. [6] Placental abruption is the reason for about 15% of infant deaths around the time of birth. [2] The condition was described at least as early as 1664. [7]
If placenta previa is present at the time of delivery, vaginal delivery is contraindicated because the placenta is blocking the fetus's passageway to the vaginal canal. Herpes simplex virus with active genital lesions or prodromal symptoms is a contraindication for vaginal delivery so as to avoid mother-fetal transfer of HSV lesions.
