What is the pathophysiology of placental abruption?

Pathophysiology. Placental abruption is where a part or all of the placenta separates from the wall of the uterus prematurely. Abruption is thought to occur following a rupture of the maternal vessels within the basal layer of the endometrium. Blood accumulates and splits the placental attachment from the basal layer.

What is the most commonly associated condition for abruption placenta?

Maternal hypertension – Most common cause of abruption, occurring in approximately 44% of all cases. Maternal trauma (eg, motor vehicle collision [MVC], assaults, falls) – Causes 1.5-9.4% of all cases. Cigarette smoking.

What is occult placental abruption?

In such cases, the blood remains “concealed” and is retained between the detached placenta and the uterus. So-called “concealed” or “occult” placental abruptions require prompt and careful diagnosis and the expeditious implementation of medical treatment to reduce both maternal and fetal risks of injury and death.

Does stress cause placental abruption?

Background. Prenatal psychological stress may increase the risk of placental abruption (PA).

Can lifting heavy things cause placental abruption?

Conclusion. The results suggest more frequent lifting of heavy objects by housewives than by employed mothers, leading to increased complications such as reduced amniotic fluid, placental abruption, and low birth weight.

Can heavy lifting cause placental abruption?

Conclusion: The results suggest more frequent lifting of heavy objects by housewives than by employed mothers, leading to increased complications such as reduced amniotic fluid, placental abruption, and low birth weight.

When to give anti-D for placental abruption?

In all cases, give anti-D within 72 hours of the onset of bleeding if the woman is rhesus D negative. Placental abruption is where a part or all of the placenta separates from the wall of the uterus prematurely. It is an important cause of antepartum haemorrhage – vaginal bleeding from week 24 of gestation until delivery.

What are the clinical features of placental abruption?

Marginal placental bleed – small, partial abruption of the placenta which is large enough to cause revealed bleeding, but not large enough to cause maternal or fetal compromise. Vasa praevia – where fetal blood vessels run near the internal cervical os.

What is the incidence of placental abruption in the Netherlands?

Ruiter L, Ravelli AC, de Graaf IM, et al. Incidence and recurrence rate of placental abruption: a longitudinal linked national cohort study in the Netherlands. Am J Obstet Gynecol 2015; 213:573.e1.

Can a placental abruption cause no vaginal bleeding?

The amount of vaginal bleeding can vary greatly, and doesn’t necessarily correspond to how much of the placenta has separated from the uterus. It’s possible for the blood to become trapped inside the uterus, so even with a severe placental abruption, there might be no visible bleeding.
