Placental examination Wikipedia

In biology, placentation refers to the formation, type and structure, or arrangement of the placenta.The function of placentation is to transfer nutrients, respiratory gases, and water from maternal tissue to a growing embryo, and in some instances to remove waste from the embryo.Placentation is best known in live-bearing mammals (), but also occurs in some fish, reptiles, amphibians, a. A placental disease is any disease, disorder, or pathology of the placenta. 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. Placenta praevia is when the placenta attaches inside the uterus but in an abnormal position near or over the cervical opening. Symptoms include vaginal bleeding in the second half of pregnancy. The bleeding is bright red and tends not to be associated with pain. Complications may include placenta accreta, dangerously low blood pressure, or bleeding after delivery Placental abruption physical examination On the Web Most recent articles. Most cited articles.

Chorioangioma. Other names. Placental hemangioma. Chorioangioma is a benign tumor of placenta. It is seen in approximately 0.5 to 1% pregnancies. It is mostly diagnosed ultrasonically in the second trimester of pregnancy. Large chorioangiomas are known to cause complications in pregnancy, while the smaller ones are asymptomatic Pathological examination of the placenta is performed for fetal, maternal, and placental indications (Table 1).The purposes are to identify fetal or maternal disease, to provide prognosis for the current and future pregnancies, to evaluate the effect of maternal disease on the pregnancy, and for legal considerations [].Many placental lesions are diagnosed solely by gross examination, and the. A placenta (fetal aspect) with attached umbilical cord. (WC/Asturnut) The placenta feeds the developing baby, breathes for it and disposes of its waste. The organ is one that seems to be left behind; at least one review suggests it isn't done so well by general pathologists. Placental pathology redirects to this article Single umbilical artery. Occasionally, there is only the one single umbilical artery (SUA) present in the umbilical cord. This is sometimes also called a two-vessel umbilical cord, or two-vessel cord. Approximately, this affects between 1 in 100 and 1 in 500 pregnancies, making it the most common umbilical abnormality. Its cause is not known

Two characteristics are particularly divergent and form bases for classification of placental types The third stage of labour is the time between when you have your baby and when the placenta (or afterbirth) comes out. (Begley et al, 2011; NICE, 2017) . Once your baby's born, the release of the hormone oxytocin will make the uterus contract and become smaller. This'll make the placenta start to separate Placental lakes can be seen within the placenta or on the fetal surface of the placenta bulging into the amniotic cavity. Slow swirling blood flow (larger arrow) may be seen within the spaces, and the shape of the spaces tends to change with uterine contractions. These features may help to distinguish a placental lakes from a thrombus Placental function is assessed using Doppler flow velocimetry of the maternal uterine and fetal umbilical arteries.

This can lead to fetal growth retardation, fetal distress, or fetal death. At times, examination of the placenta may yield causal information about. History may reveal antepartum hemorrhage. Abdominal examination usually finds the uterus non-tender, soft and relaxed. Leopold's Maneuvers may find the fetus in an oblique or breech position or lying transverse as a result of the abnormal position of the placenta. Malpresentation is found in about 35% cases.

Placental abruption. The placenta is an organ that develops in the uterus during pregnancy. Placental abruption occurs when the placenta separates from the inner wall of the uterus before birth. Placental abruption can deprive the baby of oxygen and nutrients and cause heavy bleeding in the mother. In some cases, early delivery is needed In around 20% of cases, the cause of death could be identified from careful clinical review, fetal external examination/imaging and placental examination. Traditional invasive autopsy examination itself determined the cause in a minority of cases, most remaining unexplained if the placental findings and clinical history were non-contributory

Placenta praevia ( placenta previa AE) is an obstetric complication in which the placenta is inserted partially or wholly in lower uterine segment.
