What You Need to Know About Varicose Veins and Blood Clots

You probably know that varicose veins are unsightly and that they occasionally cause discomfort, but did you know that they could also point to a more serious health problem? In extreme cases, varicose veins can be a sign of blood clots, either superficial vein thrombosis, or the more dangerous deep vein thrombosis, which can be fatal. 

Varicose veins and blood clots

People afflicted with varicose veins will notice bulging or twisted veins beneath the surface of the skin, and these obstacles can lead to sluggish blood flow. When blood flow slows, it can cause blood clots. When close to the skin, clots are considered “superficial” and not life threatening, but slowed blood flow in deeper veins is much more serious. If a piece of the clot breaks off or travels through the blood stream and up to the pulmonary arteries, it can lodge in the lungs and cause a fatal blood clot (pulmonary embolism). 

Deep vein thrombosis

While varicose veins primarily affect veins close to the surface of the skin, their existence could indicate similar problems deeper under the skin that should be identified as soon as possible. A study published in Archives of Dermatology in 2009 indicated that one in four patients with superficial vein thrombosis also had a deep vein thrombosis. Symptoms of deep vein thrombosis include pain, redness, warmth, and tenderness around the affected vein, along with swelling and redness of the affected limb.

Risk factors for varicose veins and blood clots

Varicose veins tend to run in families as an inherited condition, and other factors may increase pressure in the veins and contribute to the formation of varicose veins. These factors include obesity, older age, pregnancy, smoking, sedentary lifestyle, and leg injury. Women tend to be more susceptible to varicose veins than men. It’s important to note that contraceptive pills are not only an additional risk factor for varicose veins, but they also put women at additional risk for blood clots. Other risk factors for blood clots specifically include immobility, genetics, and injury to veins or adjacent tissues.

Diagnosis and treatment of deep vein thrombosis

Your doctor can diagnose deep vein thrombosis with blood tests and confirm with ultrasound or other imaging tests. Treatment typically involves blood thinning medications or an inferior vena cava filter if the patient cannot take anticoagulants for other medical reasons.
