The Risk of Blood Clots From Varicose Veins

May 14, 2020

Steady blood flow throughout the body is essential to nourish the delicate system responsible for maintaining healthy tissues from head to toe. Disruptions in blood flow have the potential to interrupt normal activities, cause pain, or create critical health issues. Blood clots are one of these widely recognized threats. Untreated varicose veins are a potential contributor to blood clots.


Surgery is another factor that can increase risk for blood clots. Arthroplasty is surgery to restore function of a joint, such as a hip or knee, and poses a particularly high risk for complications. The combination of untreated varicose veins in patients who undergo arthroplasty surgery has been identified as a major risk according to an extensive study published in medical journals and shared by the U.S. National Institute of Health.

Varicose veins most commonly occur in the legs. The flow of blood upward from the feet to the heart is a long journey, which competes against the forces of gravity. This strenuous process can cause a breakdown of the venous structure, leading to discoloration, swelling, and twisting of the veins, and a pooling of blood. The collection of stagnant blood in varicose veins can lead to pain, loss of function, blood clots, and other serious health issues.

how to prevent blood clots before surgery for varicose veins

Doctors now recognize the connection between the presence of varicose veins and a higher risk of post-surgical complications due to blood clots. For those asking how to prevent blood clots, many surgeons now recommend treating varicose veins prior to surgery, especially arthroplasty such as hip replacement, knee replacement, and wrist osteoarthritis reconstructive surgery.


For patients, understanding medical terms can be an important part of the treatment process. The formation of a blood clot is known as thrombosis. Varicose veins are one of many possible conditions in which blood clots can form. Blood clots can also form deep within a muscle in a serious condition known as deep vein thrombosis.

Recent medical advances have made the treatment of varicose veins a relatively common procedure, often on an outpatient basis. While you may not have a surgery scheduled, emergencies and unexpected medical procedures are also complicated by untreated varicose veins.

Now that you understand the risk of blood clots and varicose veins, you are urged to seek consultation for treatment if you suspect that you are experiencing any of the symptoms of varicose veins. Please consult a medical professional today.
