Ultrasound has also proved extremely helpful in further qualifying the risk for placenta accreta based on the presence or absence of certain characteristics, such as the presence of placental lacunae, abnormal placental vascularity as seen on color Doppler, loss of the retro placental clear zone, and myometrial thinning.

However, in cases of more deeply or widely invasive placentation these techniques are not feasible.

Houston, we have a problem! Effect of predelivery diagnosis in 99 consecutive cases of placenta accreta.

A combination of recurrent imaging with ultrasound MRI as well as the trending of beta-hCG levels has been employed in the past to help guide the timing of interval hysterectomy aiming for a balance of placental reabsorption and resolution of pelvic hyper-vascularity but this is not a widely employed strategy and does not obviate the risk of ongoing complications in the intervening time.

Pregnancy management There has been little agreement or standardization of the management of antenatally diagnosed morbidly adherent placenta. The incidence of morbidly adherent placentation has increased in the current era of obstetrics paralleling the cesarean rate.

Reviews are published on an open access basis, while original articles are made plcaentacion free online 1 year after publication. Regardless of pathophysiology which remains unclear and risk factors leading to the development of the morbidly adherent placenta, the marked increase in maternal morbidity and mortality demands careful consideration in diagnosis, pregnancy management, and ultimate delivery planning in an attempts to mitigate the many increased maternal and fetal risks associated with this condition.

In cases of conservative management due to unsuspected diagnosis of accreta or percreta deemed unresectable at the time of initial surgery, there are many adjuvant therapies that have been employed. The conservative management of placenta accreta can be viewed in two separate lights: Copy code to clipboard.
