Placenta praevia or placenta previa is when the placenta attaches inside the uterus but in a position near or over the cervical opening. [1] Symptoms include vaginal bleeding in the second half of pregnancy. [1] The bleeding is bright red and tends not to be associated with pain. [1]
This can lead to fetal malformations [2] [24] and low birth weight. [ 2 ] [ 6 ] [ 10 ] The umbilical vessels may also be longer compared to normal, [ 2 ] particularly when the site of velamentous cord insertion is in the lower uterine section as the extension of the uterine isthmus as pregnancy advances causes vessel elongation.

Placenta previa is a condition that occurs when the placenta fully or partially covers the cervix. [13] Placenta previa can be further categorized into complete previa, partial previa, marginal previa, and low-lying placenta, depending on the degree to which the placenta covers the internal cervical os.
Vasa praevia or vasa previa is a complication of obstetrics in which fetal blood vessels cross or run near the internal opening of the uterus.Since these vessels are not protected by the umbilical cord or placental tissue, the rupture of the fetal membranes during birth causes them also to rupture, leading rapidly to death of the fetus.
Histopathology of placenta with increased syncytial knotting of chorionic villi, with two knots pointed out. The following characteristics of placentas have been said to be associated with placental insufficiency, however all of them occur in normal healthy placentas and full term healthy births, so none of them can be used to accurately diagnose placental insufficiency: [citation needed]
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 ...
The one position where men would help with the birth of a child would be in the sitting position, usually when performed on the side of a bed to support the mother. [77]: 130 Men entered the field of obstetrics in the nineteenth century, resulting in a change of focus within the profession. [109]
Ischemic placental disease leads to the attachment of the placenta to the uterine wall to become under-perfused, causing uteroplacental ischemia. Where the term overarches the pathology associated with preeclampsia , placental abruptions and intrauterine growth restriction (IUGR). [ 3 ]
