Vascular system posterThe vascular system, also called the circulatory system, is made up of the vessels that carry blood and lymph through the body. The arteries and veins carry blood throughout the body, delivering oxygen and nutrients to the body tissues and taking away tissue waste matter.

The lymph vessels carry lymphatic fluid (a clear, colorless fluid containing water and blood cells). The lymphatic system helps protect and maintain the fluid environment of the body by filtering and draining lymph away from each region of the body.

A vascular surgeon specializes in a variety of techniques and procedures to repair damaged or partially-blocked blood vessels. Common vascular conditions include:

  • Aortic aneurysm
  • Blood clots
  • Carotid artery disease
  • Fibromuscular Dysplasia
  • Peripheral artery disease
  • Venous disease
