The patient presented amaurosis, high tension figures and extrahospitalary fetal death with maceration grade 1. Sonography of obstetric and gynecologic emergencies: To identify and to evaluate degenerative changes in the placental parenchyma in relationship with hypertensive disorders associated to severe abruption placentae is the aim of this work. Desrpendimiento I, Obstetric emergencies. Lesions were collected from chorionic plate, villi, vessels and intervillous space near to the surface of placental separation with llacenta microscopy to determine if such hystopathological changes are under the influence of maternal blood pressure status.
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. Chorionic degenerative chances; Hipertension; Abruptio placentae. The echogenicity of hematomas depends upon their age. Log in Sign up. The patient was unstable so she was received in cubicle of severes by a placena uterus.
Acute hematomas imaged at the time of symptoms tend to be hyperechoic or isoechoic compared to the adjacent placenta. Unable to process the form. Her mother placeta the patient had seizures but she doesn’t know the data.
Cases and figures Imaging differential diagnosis. As the hematoma is commonly isoechoic to the placenta, it may be mistaken for focal thickening of the placenta. Check for errors and try again.

Synonyms or Desprendimienyo Spellings: 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. The small vessel disease seen in abruptio placentae may also result in placental infarction. The findings exhibit increased presence of edema, necrosis, desprendimlento, fibrinoid, infarcts, syncytial knots, placfnta fibrosis, changes and inflammation of the vessel wall which were increased in placentae of hypertense pacients.
These lesions are associated to an increased area of placental separation in placentas of such pacients. Placental abruption Roland Warner and Radswiki et al. Bleeding can occasionally be ‘concealed’ as in a retroplacental hemorrhage.
The rate of placental abruption is thought to have dramatically increased in the past few years.
A ‘normal’ ultrasound does not exclude a placental abruption-particularly as the blood may previoo escaped through the vagina in the case of external hemorrhage. Patients typically present with painful vaginal bleeding with “board like” abdominal tone. Couvelaire uterus is one of the most severe complications in placental detachment occurring in 0. The exact etiology is unknown, but the final pathophysiology is likely to rupture of a spiral artery with hemorrhage into the decidua basalis leading to separation of the placenta.
Bolsa San Francisco-Caracas Venezuela http: Academia Nacional de Medicina, Palacio de las Academias. The presence of associated pervio fetal bradycardia carries a poorer prognosis.

The findings of Couvelaire Uterus are infrequent, so we must take into account this pathology because it can lead to maternal and fetal mortality. However, users may print, download, or email articles for individual use. Couvelaire uterus or uteroplacental apoplexy is a blood infiltration of the uterine myometrium due to the formation of a massive retroplacental hematoma.
If an abruption is detected, then the larger the size of the abruption, the greater the fetal morbidity.
Ten placentas were taken norminserta seven patients with hypertensive disorders and three normpinserta hypertension. 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. 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.
However, remote access to EBSCO’s databases from non-subscribing institutions is not allowed if the purpose of the use is for commercial gain through cost reduction or avoidance for a non-subscribing institution.
