Ductus venosus Doppler is a crucial ultrasound technique in obstetrics and gynecology (OBGYN) used to assess fetal well-being, particularly in high-risk pregnancies. This non-invasive method analyzes blood flow patterns through the ductus venosus, a small vessel connecting the umbilical vein to the fetal inferior vena cava. Abnormal flow, such as absent or reversed flow during…

Retained products of conception (RPOC) refer to any fetal or placental tissue remaining in the uterus after childbirth, abortion, or miscarriage. In OBGYN, this condition can lead to complications such as hemorrhage, infection, and uterine perforation. Ultrasound is a critical tool for diagnosing RPOC by visualizing endometrial thickening, irregular masses, or increased vascularity within the…

Twin gestation refers to the simultaneous development of two fetuses within the uterus, a significant area of focus in OBGYN. This multifetal pregnancy presents unique challenges and considerations for both maternal and fetal health, requiring specialized monitoring and management throughout the pregnancy. Ultrasound plays a pivotal role in early diagnosis, determining chorionicity and amnionicity, and…

Chorionicity is a critical concept in obstetrics and gynecology (OBGYN), particularly in multifetal pregnancies, referring to the number of placentas. This determination, primarily made through early ultrasound imaging, is crucial for assessing pregnancy risks and guiding management. Accurately identifying chorionicity (monochorionic vs. dichorionic) helps differentiate between twin types and predict potential complications like twin-twin transfusion…

Amnionicity refers to the number of amniotic sacs present in a multiple gestation pregnancy, a critical factor in OBGYN ultrasound. This distinction, determined early in gestation, classifies twin pregnancies as monoamniotic (one sac) or diamniotic (two sacs), profoundly impacting management and potential complications. Early and accurate assessment of amnionicity is crucial for guiding prenatal care…

Cervical length, a crucial measurement in OBGYN ultrasound, refers to the distance from the internal to the external cervical os. This assessment is vital for evaluating the risk of preterm birth, particularly in pregnancies with risk factors like a history of previous preterm delivery or certain uterine anomalies. Shorter cervical lengths can indicate an increased…

Cervical funneling, a critical finding in OBGYN ultrasound, refers to the premature widening of the internal cervical os, creating a "funnel" shape. This indicates cervical incompetence, a significant risk factor for preterm birth. Sonographic assessment includes measuring cervical length and the extent of funneling, guiding interventions to prevent adverse pregnancy outcomes. Early detection of cervical…

An ectopic pregnancy occurs when a fertilized egg implants outside the uterus, most commonly in the fallopian tube. This obstetric and gynecology (OBGYN) emergency cannot proceed to term and can lead to life-threatening internal bleeding if left untreated. Early and accurate diagnosis is critical for patient safety. Ultrasound is the primary diagnostic tool for ectopic…

A molar pregnancy, or hydatidiform mole, is an abnormal form of pregnancy resulting from a non-viable fertilization. Instead of a normal embryo, abnormal placental tissue grows, often presenting as grape-like clusters. In obstetrics and gynecology (OBGYN), accurate diagnosis is crucial to prevent complications. Ultrasound is key for identifying molar pregnancies, showing characteristic snowstorm appearance or…
