subchorionic hemorrhage / large retroplacental bleed
Retroplacental hemorrhage occurs when there is perigestational hemorrhage that is confined to the retroplacental space, Pathology This type of hemorrhage occurs behind the placenta, The hematoma, therefore, separates the placenta from the uteri
Intra- versus retroplacental hematomas: a retrospective
The subchorionic hematoma was defined as being located between the chorion and the uterine wall whereas the retroplacental hematoma was located behind the placenta The location of the hematoma was marked as anterior posterior fundal or cervical The sonographic evaluation also included the size of the hematoma relative to the gestational sac size and was characterized as small less than
Clinical Significance of Subchorionic and Retroplacental
· subchorionic hemorrhage / large retroplacental bleed 27 Posts Add message , Report, Frazzlerock Tue 28-Apr-20 10:05:44, I’ve been diagnosed with this and wondered if anyone has any personal experience? After several huge bleeds with clots I’ve had two scans and both times baby has been fine, I’m now 9+2 weeks and I saw a lovely wriggly baby yesterday, but the bleed is much bigger than 10
Clinical Significance of Subchorionic and Retroplacental
· Shallow trophoblast invasion and impaired angiogenesis with resultant friable blood vessels may predispose one to subchorionic hemorrhage as well as adverse outcomes The presence of a hematoma especially in a retroplacental location may create an area of weakness where further separation of the placenta from the uterine wall may occur resulting in placental abruption 15 ,

Hypoechoic subchorionic area at the margin of the placenta that may be difficult to distinguish from the normal retroplacental venous plexus Color doppler is useful as hematoma shows little or no blood flow whereas the retroplacental plexus is extremely vascular, Acute hemorrhage = hyperechoic to isoechoic in the first week similar to the surrounding placental tissue and therefore may be
The effects of subchorionic hematoma on pregnancy outcome
A subchorionic hemorrhage places the gestation at increased risk of: placental abruption 4,6; preterm labor 6; If the collection extends up to the internal os and/or there is dilatation of the internal cervical os, this is an indication of extremely poor prognosis, almost always leads to impending miscarriage, Differential diagnosis, General imaging differential considerations include
subchorionic hemorrhage and retroplacental hemorrhage in the evaluation of adverse pregnancy outcome a separate analysis was performed on studies that limited their analysis to subchorionic hemorrhage Statistical Analysis For dichotomous factors, both fixed-effects and random-effects models were utilized to obtain pooled RR and 95% CIs,11,12 Fixed-effects models assume that risk is

retroplacental vs subchorionic hemorrhage
· Prominent retroplacental and myometrial vessels should be distinguished from heterogeneous bleeding The vessels appear as serpentine, anechoic structures and demonstrate flow on color Doppler
Retroplacental hemorrhage
· Retroplacental hematomas seemed to have developed significantly earlier which is suggested by the lower gestational age at initial diagnosis median 13 vs 24 weeks In these earlier weeks of gestation significant impairment of fetal perfusion more likely leads to IUFD One might also argue that smaller and, thus, more irrelevant retroplacental hematomas that developed early did not cause
