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 risk, prompting closer monitoring and potential interventions.
In medical ultrasound, precise cervical length measurement helps guide clinical management. Serial evaluations can track changes over time, aiding in the proactive identification of women who may benefit from interventions such as progesterone therapy or cerclage. This non-invasive OBGYN diagnostic tool is fundamental for managing high-risk pregnancies and improving neonatal outcomes.
