Introduction

Single umbilical artery refers to a condition in which the fetal umbilical cord contains only one artery and one vein, whereas normally there should be two arteries and one vein. Single umbilical artery is an abnormality that may restrict the fetus's ability to receive nutrients and oxygen, thereby affecting its growth and development. This can lead to problems such as fetal malnutrition and developmental delay, and is generally considered a high-risk pregnancy.

Single umbilical artery is generally considered a high-risk pregnancy and requires prompt management. The specific analysis is as follows:

A single umbilical artery refers to a fetal umbilical cord containing only one artery and one vein, whereas normally there should be two arteries and one vein. This condition is an anomaly that may restrict the fetus's ability to receive adequate nutrients and oxygen, thereby affecting its growth and development. It may lead to fetal malnutrition, growth restriction, and other problems, and is typically classified as a high-risk pregnancy. Close monitoring of fetal growth and development is recommended, along with regular prenatal check-ups and ultrasound examinations as directed by a physician. Additionally, if necessary, further tests such as fetal echocardiography and chromosomal analysis may be performed to rule out potential structural or chromosomal abnormalities.

If any abnormalities occur in the fetus or mother, prompt medical attention should be sought, and treatment should be administered according to medical advice.

What does it mean when a fetus has only one umbilical cord?

The fetus has only one umbilical artery, typically characterized by the absence of one of the two normal umbilical arteries, resulting in a single umbilical artery and vein, along with possible abnormalities in the umbilical arteries or vein, or umbilical cord ligation. This condition, known as single umbilical artery (SUA), may be associated with fetal cardiac and urinary system developmental anomalies. The primary treatment approach involves close monitoring of fetal growth and development, with appropriate management based on the specific clinical situation.
