	#~~redirect~~ [[~~Placenta~~#~~Placental~~ abruption]]		'''Placental abruption''' is premature separation of the [[placenta]] from the [[uterus]].

			==General==
			Classic clinical manifestations:<ref name=pmid16752262>{{cite journal \|author=Tikkanen M, Nuutila M, Hiilesmaa V, Paavonen J, Ylikorkala O \|title=Clinical presentation and risk factors of placental abruption \|journal=Acta Obstet Gynecol Scand \|volume=85 \|issue=6 \|pages=700–5 \|year=2006 \|pmid=16752262 \|doi=10.1080/00016340500449915 \|url=}}</ref>
			*Vaginal bleeding (~70%).
			*Abdominal pain (~50%).
			*Fetal heart rate abnormalities (~70%).

			Sign-out:
			*Pathologists should sign-out this as "focal adherent retroplacental hematoma".
			**The pathologic findings may be due to abruption or manual removal of the placenta.

			==Gross==
			Features:<ref>CS. 7 February 2011.</ref>
			*Large adherent blood clot.
			*Disc depression on maternal side.

			Notes:
			*Loosely attached clot less convincing.
			*Central haemorrhage is the most worrisome.

			==Microscopic==
			Features:
			#Decidual hemorrhage.
			#*Blood in the decidua.
			#Intravillous hemorrhage, [[AKA]] villous stromal hemorrhage.
			#*"Bags of blood" - blood outside of vessels in the villi.
			#**Should not be confused with congested villi.

			Notes:
			*There are '''no''' definitive microscopic findings for placental abruption.
			*Intravillous hemorrhage is non-specific - may arise in the following: early placental infarct, cord compression, abdominal trauma.
			==Sign out==
			===Usual nonspecific findings===
			<pre>
			PLACENTA, UMBILICAL CORD AND FETAL MEMBRANES, BIRTH:
			- THREE VESSEL UMBILICAL CORD WITHIN NORMAL LIMITS.
			- FETAL MEMBRANES WITHIN NORMAL LIMITS.
			- PLACENTAL DISC WITH THIRD TRIMESTER VILLI, TWO SMALL PLACENTAL INFARCTS
			(0.8 CM AND 0.5 CM IN MAXIMAL DIMENSION) AND FOCAL PROMINENCE OF SYNCYTIAL KNOTS.

			COMMENT:
			There is no decidual hemorrhage or intravillous hemorrhage. The prominent syncytial knots
			are a nonspecific finding suggestive of (focal) ischemia.
			</pre>
			Note:
			*The above is not diagnostic nor does it exclude the diagnosis of abruption.
