“…Blood contamination was significantly higher when transplacental amniocentesis was performed [17] . Chinn et al [18] also observed higher blood contamination estimated by ultrasound in transplacental amniocentesis. Amniotic fluid contamination with maternal cells is observed in up to 85% of transplacental procedures, and in 10% when the placenta is posterior [19] .…”

The risk of transmission of human immunodeficiency virus (HIV), hepatitis B (HBV) and hepatitis C virus (HCV) during invasive procedures may not be negligible, although it has been poorly assessed. The risk of hepatitis B transmission during amniocentesis seems to be low, but it may be increased in women with a positive HBeAg. HCV transmission risk cannot be established because evidence is lacking. No information exists about other invasive procedures in such infections. An increased risk of vertical transmission following an invasive procedure was suggested in HIV infection, but amniocentesis seems to be safe when performed under highly active antiretroviral treatment, with a low viral load and when avoiding placental passage. International guidelines do not clearly define policies to screen for maternal blood-borne virus infection during invasive procedures. Nevertheless, serological status should be assessed in all cases and parents should be aware of the existing evidence for transmission risk. Transplacental amniocentesis should always be avoided.

“…Intra-amniotic hemorrhages can be the result of an amniocentesis [ 1 ] or bleeding from the placenta [ 2 ], or can occur spontaneously [ 3 ]. The most frequently performed procedure that is a cause of intra-amniotic bleeding is amniocentesis [ 4 ].…”

“…The most frequently performed procedure that is a cause of intra-amniotic bleeding is amniocentesis [ 4 ]. A study reported that If the amniocentesis involves the passage of a needle through the placenta, then the risk of intra-amniotic bleeding was 100% [ 1 ]. An amniocentesis may be useful in helping make the diagnosis of an intra-amniotic hemorrhage when the diagnosis is uncertain.…”

Intra-Amniotic Hemorrhage Imitating Gastroschisis: A Case Report and Review of the Literature

Patient: Female, 33Final Diagnosis: Intramamniotic hemorrhageSymptoms: Abdominal pain • uterine contractions • vaginal bleedingMedication: —Clinical Procedure: Cesarean deliverySpecialty: Obstetrics and GynecologyObjective:Unusual clinical courseBackground:A spontaneous intra-amniotic hemorrhage is rarely encountered during pregnancy. The correct diagnosis and management are problematic because of the infrequency of this condition and the high likelihood of a misdiagnosis.Case Report:A primigravida with an uncomplicated pregnancy and a normal targeted ultrasound presented late in the second trimester of pregnancy with antepartum bleeding of unknown origin. A repeat ultrasound was suggestive of an abdominal wall defect (gastroschisis). The patient continued to have antepartum bleeding and developed uterine contractions and abdominal pain necessitating frequent visits to labor and delivery. An MRI ruled out gastroschisis and diagnosed intra-amniotic hematoma. The patient presented with acute abdominal pain and was clinically considered to be having an abruption, and was delivered by cesarean. Old blood was noted in the abdominal cavity and within the uterine cavity. At the time of the cesarean, an area of intra-amniotic hematoma was identified, as well as a retroplacental blood clot.Conclusions:An intra-amniotic hematoma is unusual and may be misdiagnosed. MRI may be helpful in determining the correct diagnosis and subsequent management.
