The rate of placental abruption is thought to have dramatically increased in the past few years. Patients typically present with painful vaginal bleeding with “board like” abdominal tone. Bleeding can occasionally be ‘concealed’ as in a retroplacental hemorrhage.

The exact etiology is notmoinserta, but the final pathophysiology is likely to rupture of a spiral artery with hemorrhage into the decidua basalis leading to separation of the placenta.

The small vessel disease seen in abruptio placentae may also result in placental infarction. Ultrasound is almost always the first and usually the only imaging modality used to evaluate placental abruption, but an index of suspicion should be maintained for the diagnosis since ultrasound is relatively insensitive for the diagnosis 9.

The echogenicity of desprendimieno depends upon their age. Acute hematomas imaged at the time of symptoms tend to be hyperechoic or isoechoic compared to the adjacent placenta. As the hematoma is commonly isoechoic to the placenta, it may be mistaken for focal thickening of the placenta.

A ‘normal’ ultrasound does not exclude a placental abruption-particularly as the blood may have escaped through the vagina in the case of external hemorrhage.

Since placental abruption is a concern in a pregnant patient who has undergone traumatic injury, CT is occasionally the first imaging modality used to evaluate the placenta. The appearance of the placenta in the trauma patient is reviewed at ” traumatic abruption placenta scale TAPS “. MR imaging can accurately detect placental abruption and should be considered after negative US findings in the presence of late pregnancy bleeding if the diagnosis of abruption would change management.

[Immediate response team. 59 cases with obstetric hemorrhage].

Hemorrhage due to abruption appears as an area of medium to high signal intensity on T1 and high signal intensity on a T2 weighted image, located between the placenta and uterine wall.

Given the low sensitivity for detecting placental abruption on ultrasound, if there is a high clinical suspicion, then it is likely prudent to treat based on the clinical suspicion 9. If an abruption is detected, then the larger the size of the abruption, the greater the fetal morbidity. The presence of associated concurrent fetal bradycardia carries a poorer prognosis.
