What is a frequent consequence of an extra-long umbilical cord?

An extra-long umbilical cord can lead to transient decelerations in the fetal heart rate. This occurs because the length of the cord can contribute to increased mobility of the fetus, which may result in cord compression during various movements or contractions. When the cord is compressed, it can temporarily reduce blood flow and oxygen delivery to the fetus, causing decelerations in the heart rate that are usually transient and resolve quickly once the pressure is relieved.

The phenomenon can be monitored during labor, and while it may raise concerns, transient decelerations are often benign and not a direct indication of fetal distress. Therefore, recognizing this association helps healthcare professionals understand fetal monitoring patterns and respond appropriately.

In contrast, other options may suggest more serious complications; however, they are less frequently associated with an extra-long umbilical cord specifically. For example, fetal death and maternal hemorrhage involve significantly different risk factors and mechanisms that are not primarily linked to cord length.
