Pregnancy is an extraordinary journey, especially when one is carrying more than one fetus, this may be twins or triplets. Handling multiple pregnancies demands personalized attention and strict observation. Ultrasound is an important diagnostic tool for monitoring and managing twin pregnancies; it does not involve invading the body and generates images through sound waves The Importance of Ultrasound Assessment in Twins and Triplets’ Context.
The Importance of Early Ultrasound Assessment:
Early ultrasound assessment in a multiple gestation pregnancy is crucial for several reasons:
1. Confirming the Number of Fetuses:
An ultrasound done in the first tri-semester always gives the total number of fetuses. They are necessary to exclude potential missed multiples and create a baseline for future surveillance.
2. Determining Gestational Age:
Dating of this pregnancy will be appropriate specifically in multiple gestations because growth patterns might differ with different fetuses. This allows tracking the development of each fetus.
3. Identifying Chorionicity and Amnionicity:
It is important to determine the chronicity in twin pregnancies-whether it is one or two placentas and one or two amnionic sacs. Twins can be classified into three main categories:
Monochorionic-Monoamniotic (MCMA): The highest risk category with identical twins sharing both a placenta and an amniotic sac.
Monochorionic-Diamniotic (MCDA): Identically formed by two eggs in one womb, yet in separate compartments.
Dichorionic-Diamniotic (DCDA): Non-identical twins, both having individual placentas and amnion sacks.
The degree of risk and monitoring needed during the pregnancy depends on chorionicity and amnionicity.
Monitoring Fetal Growth and Development:
The ultrasound helps monitor fetal growth during the entire pregnancy. Key factors include:
1. Fetal Growth: Ultrasound checks whether each fetus is increasing in size and weight according to the term of pregnancy.
2. Vital Organs: On the other hand, detailed ultrasound scans are used for the structure and function of important organs like the heart, the brain, and the kidneys to pinpoint any abnormalities that may occur.
3. Amniotic Fluid Levels: An integral aspect of monitoring involves checking amniotic fluid levels to detect any anomalies such as oligohydramnios and polyhydramnios which could be indicative of poor fetal well-being.
4. Placental Health: Regular scans are checking on both your baby’s growth and your placenta (s) as placental problems may affect how your baby is developing.
5. Umbilical Cord Blood Flow: Similarly, doppler ultrasound can determine the rate of blood flow in the umbilical cords, which is important as it offers information about the delivery of oxygen and nourishment to the unborn
Identifying and Managing Complications:
Ultrasonography is instrumental in identifying potential complications in multiple gestations, including:
1. Twin-to-Twin Transfusion Syndrome (TTTS):
Twin-to-twin transfusion syndrome occurs in MCDA twins where the unequal distribution of blood among the two fetuses happens via the placenta. It is used to diagnose TTTS and guide interventions like amnioreduction or laser therapy to achieve normalization of blood circulation.
2. Growth Discordance:
Growth discordance is when one of the twins is significantly larger than the other. Ultrasound allows the discovery of growth problems early so that the smaller twin can grow better by taking certain interventions.
3. Preterm Labor and Delivery Risk:
Preterm births were more frequent in multiple pregnancies. Ultrasound enables doctors to monitor cervical length evaluate the chances of preterm labor and institute preventive measures.
4. Breech Presentation:
In this case, ultrasound is helpful, as it reveals the precise placement of each fetus, important for decision-making about the delivery method; especially if one or more fetuses are present in a breach.
5. Placental Abnormalities:
Ultrasound allows early identification and management of maternal complications associated with placentation, for example, placenta previa or abruption.
Timing and Frequency of Ultrasound Scans:
Ultrasound scanning may be carried out at different timings or frequencies for multiple gestations, depending on some variables such as chorionicity, maternal health conditions, or the existence of complications. Nevertheless, schedules often are made of two routine scans: the earliest one can be made in approximately 18-20 weeks of the first trimester and the other within the 3rd trimester. Further scans, if desired/required, will be monitored or for special purposes.
Ultrasound Evaluation of Multiple Gestation Pregnancies. This empowers physicians to track an unborn baby’s growth while detecting possible problems in time, thus ensuring good health for both a mother and her children. Health-care teams may offer specialized care, provide interventions as needed, and enhance the likelihood of good outcomes in multiple gestations. Multipreterus birth-weight outcomes can be improved by the use of early and frequent prenatal scans making safer
