ACRETA INCRETA PERCRETA PDF

Placenta accreta is an abnormal adherence of the placenta to the uterine wall that can lead to significant maternal morbidity and mortality. The incidence of placenta accreta has increased fold since the early s and directly correlates with the increasing cesarean delivery rate. The prenatal diagnosis of placenta accreta by ultrasound along with risk factors including placenta previa and prior cesarean delivery can aid in delivery planning and improved outcomes. Referral to a tertiary care center and the use of a multidisciplinary care team is recommended.

Placenta Accreta

Placenta accreta occurs when the placenta—the organ that provides nutrients and other support to a developing fetus—attaches too deeply to the uterine wall. This is a serious condition that can cause complications for the baby and mother, especially during the delivery. With supervision by experienced clinicians, however, these complications and risks can be managed effectively. Obstetricians seek to make a specific diagnosis of accreta, increta or percreta before delivery using ultrasound and MRI imaging, but this is not always possible. Women who have experienced one or more of the following factors are at a higher risk for this condition:. Placenta accreta generally has no symptoms. However, placenta previa , which often develops along with accreta, often presents with vaginal bleeding.

Placenta Accreta, Increta, and Percreta

Three variants of abnormally invasive placentation are recognised: placenta accreta, in which placental villi invade the surface of the myometrium; placenta increta, in which placental villi extend into the myometrium; and placenta percreta, where the villi penetrate through the myometrium to the uterine serosa and may invade adjacent organs, such as the bladder. Placenta accreta, increta, or percreta is associated with major pregnancy complications, including life-threatening maternal haemorrhage, large-volume blood transfusion, and peripartum hysterectomy. The existing literature consists predominately of case reports, and studies undertaken using retrospective review of medical records, over a number of years in a single or small number of tertiary-care institutions. The aims of this study were to prospectively identify a national population-based cohort of women with placenta accreta, increta, or percreta to describe the current management of this condition in the UK, and the associated outcomes for women and their infants, in order to inform future practice guidelines. Cases included all women identified as having placenta accreta, increta or percreta, defined as either placenta accreta, increta, and percreta diagnosed histologically following hysterectomy, or post-mortem, or an abnormally adherent placenta, requiring active management, including conservative approaches where the placenta is left in situ. Data collection forms were then sent to the clinicians who reported a case to confirm the diagnosis and request further information concerning potential risk factors, management, and outcomes.
