Causes of Venous Congestion in the Head and Neck
Disease description:
I have been experiencing dizziness and blurred vision recently, so I went in for a checkup. The results indicated venous congestion. I would like to learn more about the possible causes of venous congestion in the head and neck.

There are several causes of venous congestion in the head and neck region, including but not limited to the following:
1. Impaired venous return: When the veins responsible for returning blood are compressed or obstructed by thrombi, septa, or other impediments, venous blood flow becomes impaired, leading to venous congestion in the head and neck.
2. Venous valve insufficiency: Venous valves are crucial structures that ensure unidirectional blood flow. When valve function is compromised, blood from the deep veins may reflux into the superficial veins, causing venous stasis in the superficial vessels and subsequently leading to venous congestion in the head and neck.
3. Cardiac insufficiency: Particularly when right heart function is compromised, the heart is unable to pump blood effectively into the pulmonary circulation, resulting in blood congestion in peripheral tissues, including the head and neck, thereby causing venous congestion.
4. Superior vena cava obstruction syndrome: Obstruction of the superior vena cava caused by tumors, thrombosis, or other factors can impair venous return, resulting in congestion and swelling in areas such as the head, neck, and upper limbs.
5. Lifestyle habits: Prolonged desk work or maintaining poor neck posture for extended periods may also lead to venous congestion in the head and neck region.
