A vascular surgeon is a medical doctor who specializes in diagnosing and treating conditions that affect the circulatory system, including the arteries, veins, and lymphatic vessels. Vascular surgeons are trained in surgical procedures to treat diseases and disorders of the circulatory system, such as aneurysms, peripheral artery disease, and deep vein thrombosis. They also perform minimally invasive procedures, such as endovascular surgery, to treat these conditions. Vascular surgeons work with a team of healthcare professionals to provide comprehensive care to patients with vascular problems.
