Ultrasound showing a subchorionic hemorrhage [1] Chorionic hematoma is the pooling of blood ( hematoma ) between the chorion , a membrane surrounding the embryo , and the uterine wall . [ 2 ] It occurs in about 3.1% of all pregnancies , [ 2 ] it is the most common sonographic abnormality and the most common cause of first trimester bleeding .
Breus' mole is diagnosed antenatally by ultrasound, where a thick multilobulated hematoma can be seen beneath the chorion. Occasionally, subchorionic thrombohematoma may later become intraplacental, making its diagnosis difficult. The mole may be echogenic or hypoechoic depending upon the amount of fresh blood present in it. [3]
It is the most common cause of early pregnancy bleeding and is associated only with heavy (versus light) bleeding. [8] However, patients typically remain hemodynamically stable. Threatened early pregnancy loss, often considered a type of early pregnancy loss, refers vaginal bleeding in the presence of an intrauterine pregnancy and a closed cervix.
Bleeding in excess of this norm in a nonpregnant woman constitutes gynecologic hemorrhage. In addition, early pregnancy bleeding has sometimes been included as gynecologic hemorrhage, namely bleeding from a miscarriage or an ectopic pregnancy, while it actually represents obstetrical bleeding. However, from a practical view, early pregnancy ...
It takes place in normal pregnancies as well as when there are obstetric or trauma related complications to pregnancy. Normally the maternal circulation and the fetal circulation are kept from direct contact with each other, with gas and nutrient exchange taking place across a membrane in the placenta made of two layers, the syncytiotrophoblast ...
Hormone levels, bleeding, a positive pregnancy test and an ultrasound of an empty uterus all indicate an ectopic pregnancy. “You can't be 100% — that's the tricky part," said Kate Arnold, an ...
Antepartum bleeding (APH), also prepartum hemorrhage, is bleeding during pregnancy from the 24th week [7] (sometimes defined as from the 20th week [8] [7]) gestational age up to the birth of the baby. [5] The primary consideration is the presence of a placenta previa which is a low lying placenta at or very near to the internal cervical os.
The presence of severe vaginal infections at the time of pregnancy may cause minor antepartum haemorrhaging. For example, the presence of chlamydia, thrush, cervicitis or other infections are all irritants to the vaginal and cervical lining, causing bleeding from those surfaces where the infection is severe. [23] Cervical canal and distal ...
