The Science Behind Vascular Surgery: Understanding the Anatomy of Blood Vessels

Science Behind

What is Vascular Surgery?

Vascular surgery is a specialized medical field which focuses on surgical treatments to conditions related to the circulatory system, including arteries, veins and lymphatic vessels. Through vascular surgery,  diseases and diseases of the circulatory system can be treated to help improve or restore patient’s overall health and well-being.

Understanding the Anatomy of Blood Vessels and Health

In order to explain the science behind vascular surgery, it’s important to first understand the anatomy of blood vessels and the impact blood vessel health has on the body. Our bloodstreams carry blood to and from our hearts, oxygenating and cleansing our cells and organs. This flow of blood is enabled by a network of arteries, veins and capillaries. Healthy blood vessels are flexible and strong, and are able to expand and contract to accommodate the body’s needs.

When our vessels are unhealthy, they become a major risk factor in numerous diseases such as stroke, coronary artery disease, and peripheral arterial disease. The knowledge of the anatomy of blood vessels and the effects of vessel health on body health gives us insight into why vascular surgery is such an important medical field.

What Does Vascular Surgery Treat?

Vascular surgery addresses various diseases related to the circulatory system, such as:

  • Varicose Veins: Unhealthy valves in the veins of the legs can cause them to become swollen and twist, leading to the condition known as varicose veins.
  • Aneurysms: Aneurysms are weak spots in the walls of the vessels that cause them to bulge, potentially leading to major health issues if left untreated.
  • Vascular Abnormalities Affecting the Limbs: Obstructive lesions in vessels can lead to poor circulation in the limbs, which can in turn result in pain and possibly even ulcers.
  • Carotid Artery Disease: This condition is caused by blockages in the carotid artery, leading to strokes and other health issues.

How Does Vascular Surgery Work?

Vascular surgery is a minimally invasive procedure, using advanced imaging technologies to diagnose and treat vascular conditions. A range of treatments is available, from endovascular surgery to sclerotherapy, stenting, bypasses and more. Depending on the type of treatment, various scopes, catheters and other equipment may be used.


Vascular surgery is a specialized medical field which focuses on surgery to the circulatory system to treat diseases and conditions related to vessel health. Understanding the anatomy of blood vessels and the effects of unhealthy vessels on the body is essential in order to appreciate the importance of vascular surgery. Various treatments are available and the minimally invasive methods used and the advanced technology used give surgeons the ability to diagnose and treat vascular diseases accurately and effectively.
