Signs and symptoms of pregnancy are common, benign conditions that result from the changes to the body that occur during pregnancy. Signs and symptoms of pregnancy typically change as pregnancy progresses, although several symptoms may be present throughout. Depending on severity, common symptoms in pregnancy can develop into complications ...
As there is no treatment for triploidy, palliative care is given if a baby survives to birth. If triploidy is diagnosed during the pregnancy, termination is often offered as an option due to the additional health risks for the mother (pre-eclampsia, a life-threatening condition, or choriocarcinoma, a type of cancer). Should a mother decide to ...
The twin reversed arterial perfusion, or T.R.A.P. sequence, results in an 'acardiac twin', a parasitic twin that fails to develop a head, arms and a heart.The parasitic twin, little more than a torso with or without legs, receives its blood supply from the host twin by means of an umbilical cord-like structure, much like a fetus in fetu, except the acardiac twin is outside the autosite's body.
Antenatal twin anemia-polycythemia sequence classification. [6] Antenatal stage Results of a Doppler ultrasound scan Stage 1 MCA-PSV donor >1.5 MoM and MCA-PSV recipient <1.0 MoM, without other signs of fetal compromise Stage 2 MCA-PSV donor >1.7 MoM and MCA-PSV recipient <0.8 MoM, without other signs of fetal compromise Stage 3
Early deliveries are often used to advance the start of treatment. Surgery is generally safe, but pelvic surgeries during the first trimester may cause miscarriage. Some treatments, especially certain chemotherapy drugs given during the first trimester, increase the risk of birth defects and pregnancy loss (spontaneous abortions and stillbirths ...
The acardiac twin is a parasitic twin that fails to properly develop a heart, and therefore generally does not develop the upper structures of the body. The parasitic twin, little more than a torso with or without legs, receives its blood supply from the host twin by means of an umbilical cord-like structure (which often only has two blood vessels, instead of three), much like a fetus in fetu ...
[5] Vanishing twin syndrome has been characterized as the loss of a twin before 12 weeks of gestation, or early during the first trimester where it is uncommon for twin pregnancy to have been identified. [6] According to Boklage, most twin pregnancies are ultimately born as singles, and vanished twins are a possible source of abnormal cells. [7]
The presence of subchorionic bleeding around the gestational sac does not have a significant association with miscarriage overall. [8] [9] However, the case of intrauterine hematoma observed before 9 weeks of gestational age has been associated with an increased risk of miscarriage. [10]
