Where the placenta covers part of the cervix, or in the worst case a ‘total’ placenta previa, where the entire cervical os is covered by placenta 8 whilst the definitive cause of placenta. Placenta previa is the development of placenta in the lower uterine segment, partially or completely covering the internal cervical os the cause is unknown, but a possible theory states that the embryo will implant in the lower uterine segment if the deciduas in the uterine fundus is not favorable. Placenta previa is a condition in which the placenta attaches to the uterine wall in the lower portion of the uterus and covers all or part of the cervix classification of placenta previa 1 total previa- the placenta completely covers the internal cervical os. Purpose the purpose of this case study is to discuss the obstetric condition involved with placenta praevia with the occurrence of a placental abruption in a woman who uses amphetamines during pregnancy and the midwifery and obstetric care involved.

Placenta previa is the abnormal implantation of the placenta in the lower uterine segment, where it encroaches on the internal cervical osone of the most common causes of bleeding during the second half of the pregnancy,this disorder occurs in about 1 in 200 pregnancies more commonly in multi gravidas than in primigravidas if the patient has heavy maternal bleeding and then is diagnosed with.

Placenta percreta is one of the most serious complications of placenta previa and is frequently associated with severe obstetric hemorrhage usually necessitating hysterectomy we present a case of placenta previa percreta diagnosed by ultrasound and magnetic resonance imaging techniques, in which we accomplished conservative management of postpartum hemorrhage. A case-cohort study was performed to clarify and compare the risk factors for placental abruption and placenta previa this study reviewed 242,715 births at 125 centers of the perinatal network in.
Background: the risk factors of placenta previa differ around the worldthis study evaluated risk factors of pregnancies complicated with placenta previa during a 5-year period in a referral center in hamadan, iran.

Introduction placenta previa is an implantation of the placenta in the lower uterine segment, near or over the internal cervical os, and is usually seen in the third trimester this tends to occur in 1 out of every 200 pregnancies, can be caused by many different reasons and there several different types.
Objective concurrent placenta previa and placenta accreta increase the risk of massive obstetric hemorrhagedespite extensive research on the management of placenta previa (including placenta accreta, increta, and percreta), the number and quality of previous studies are limited. In this study 064% of the deliveries were complicated with placenta previa among them 236% women were above 30 years of age and 802% were multigravidas 604% had major degree placenta previa, 368% had prior. In placenta previa, the placenta is attached low in the uterus over or near the internal cervical osthe degree of severity depends on placental placement the least severe degree is low implantation or low‑lying placenta, in which the placenta is implanted in the lower uterine segment close to the os. Introductionplacenta previa is a condition in which the placenta is located low in the uterine cavity, partially or completely covering theopening of the cervix this can cause bleeding and interfere with a normal vaginal delivery. Placenta previa in the second trimester puts the client at risk for developing vasa previa and thought to be a result of inflammatory atrophic changes to the placenta in the third trimester, placenta previa is the leading cause of painless bleeding leading to hemorrhage.
In cases of placenta previa, the percentage of placenta accreta was 33%, 11%, 40%, 61%, and 67% at the first, second, third, fourth, and fifth previous caesareans, respectively 2 therefore, as in the present case, it is fundamental to highlight a diagnostic suspicion in the case that a placenta previa coexists with the antecedent of caesarean. Placenta previa defined as a condition that occurs in pregnancy when the placenta abnormally implanted in the lower uterine segment, partially or totally covering the internal cervical os1 complete placenta previa is when it covers the internal os, partial is when the placenta partially covers the os, and marginal is when the placenta.

Relationship among placenta previa, fetal growth restriction, and preterm delivery: a population-based study obstet gynecol 2001 98:299 räisänen s, kancherla v, kramer mr, et al placenta previa and the risk of delivering a small-for-gestational-age newborn. The authors present a case of 38 years old woman whit complete placenta previa who comes to the er of their ho pital complex with plenty of vaginal blee diagnosis of placenta previa is mainly ultrasound. Placenta previa is important and useful in clinical obstetrical practice (8) numerous studies have demonstrated that transvaginal ultrasonography is a sensitive and specific tool for accurate depiction of the placental location when placenta previa is suspected. Study shows that most common type of placenta previa seen in the study group was type i with 13 cases, 1 patient had type iii placenta previa and 5 patients each of type ii and iv while in control group there.
In placenta previa, the placenta does not embed correctly and results in what is known as a low-lying placenta it can be marginal, partial, or complete in how it covers the cervical os, and it increases the patient’s risk for painless vaginal bleeding during the pregnancy and/or delivery process. Study design: we reviewed studies on placenta previa published between 1950 and 1996 on the basis of a comprehensive literature search with use of medline and by identifying studies cited in the references of published reports studies were chosen for inclusion in the metaanalysis if the incidence of placenta previa and its cross-classification.
