What is the most common cause of early pregnancy bleeding?
Miscarriage (abortion), ectopic pregnancy, molar pregnancy, and pregnancy implantation.
What percentage of pregnancies experience early pregnancy bleeding?
20-40% of pregnancies.
What are the different types of miscarriage?
Threatened, inevitable, incomplete, complete, missed, and septic.
What is the definition of a ‘missed miscarriage’?
A miscarriage where the fetus is no longer viable, but the fetus has not been expelled.
What is a septic miscarriage?
A miscarriage that is complicated by infection, leading to symptoms like fever, foul-smelling discharge, and possibly shock.
What is the first-line treatment for a threatened miscarriage?
Reassurance, rest, and monitoring via repeated ultrasound.
What is the treatment for an incomplete miscarriage?
Dilation and curettage (D&C) or suction evacuation, depending on the situation.
How is a missed miscarriage typically managed?
It can be managed expectantly, with the patient being asked to wait for spontaneous expulsion, or it may require surgical intervention if expulsion does not occur within 4 weeks.
What are some common fetal causes of miscarriage?
Chromosomal abnormalities (e.g., trisomy, monosomy, triploidy).
What are some maternal causes of miscarriage?
Uterine abnormalities (e.g., fibroids, septate uterus), cervical incompetence, endocrine disorders, infections, and trauma.
What is the difference between a complete miscarriage and an incomplete miscarriage?
In a complete miscarriage, all products of conception are expelled, while in an incomplete miscarriage, some products remain in the uterus.
What is an ectopic pregnancy?
A pregnancy that occurs outside the uterus, commonly in the fallopian tubes.
What are the risk factors for ectopic pregnancy?
Previous tubal surgery, IUD use, in vitro fertilization, smoking, and history of pelvic inflammatory disease (PID).
What is the gold standard for diagnosing an ectopic pregnancy?
Laparoscopy.
What is the treatment for a stable ectopic pregnancy?
Methotrexate is used to treat ectopic pregnancy in stable patients with a small mass (less than 3.5 cm) and no fetal heart activity, helping to dissolve the pregnancy tissue.
What is the difference between salpingostomy and salpingectomy in treating ectopic pregnancy?
Salpingostomy is the removal of the ectopic pregnancy while preserving the fallopian tube, whereas salpingectomy involves the removal of the entire tube.
What is the role of methotrexate in the management of ectopic pregnancy?
Methotrexate is a folic acid antagonist used in non-ruptured ectopic pregnancies to stop cell division and allow reabsorption of the pregnancy.
What is the role of β-HCG in diagnosing early pregnancy complications?
β-HCG levels help monitor pregnancy progression. A slow rise or failure to double every 48 hours can suggest an abnormal pregnancy, such as an ectopic pregnancy or miscarriage.
What does an ultrasound show in cases of a missed miscarriage?
The ultrasound will show an empty gestational sac or a sac with no fetal heart activity, indicating the pregnancy is non-viable.
What does the ‘double sign’ on ultrasound indicate?
The ‘double sign’ refers to the presence of both the gestational sac and a surrounding echogenic ring, which is characteristic of an ectopic pregnancy.
What is the ‘snowstorm appearance’ seen on ultrasound in a molar pregnancy?
The ‘snowstorm appearance’ is characterized by an absence of a fetus and the presence of grape-like clusters of trophoblastic tissue, indicative of a molar pregnancy.
What is the initial treatment for a molar pregnancy?
The treatment involves evacuation of the molar tissue through dilation and curettage (D&C) to prevent complications like severe bleeding.
What is the follow-up protocol after evacuation of a molar pregnancy?
Weekly β-HCG monitoring is done until the levels become negative for three consecutive weeks, after which monthly monitoring is performed for a year to detect recurrence or malignancy.
