What You Need to Know About Deep Vein Thrombosis (DVT)

Deep Vein Thrombosis, or DVT, is a common condition that many people may not be aware of. Though a DVT can have serious and sometimes life threatening complications, it can be prevented. Here, Dr. Kokkosis explains the signs and symptoms of DVT and how the Center for Vein Care at Stony Brook can treat these and other vein diseases.

What is Deep Vein Thrombosis (DVT)?
Deep vein thrombosis, also know as DVT, is a blood clot in a deep vein that can form due to immobility, congenital conditions, pregnancy, cancer or other conditions that affect the flow of blood in the veins. It usually appears in the legs but can also occur in the pelvis or arm. These blood clots can be dangerous if they break off and travel to the lungs. When this happens, it causes a serious condition called a Pulmonary Embolism (PE). Because of this, the lungs can be damaged by lack of blood flow and a lack of oxygen, so it’s best to seek medical attention as quickly as possible.

How is DVT diagnosed?
To determine if DVT is present, we will obtain your medical history and perform an examination. Diagnostic testing may include noninvasive procedures (Duplex ultrasound or D-dimer test), or minimally invasive procedures like a CT Venogram (imaging tests that use IV contrast and a specialized CT scan) or a Venography (a dye is injected into a vein of the affected leg making the vein visible on an x-ray image).

What are the symptoms of DVT?
Around half of people with DVT have no symptoms at all. If symptoms do occur, they may include swelling of the leg, pain or tenderness in the leg or increased warmth or redness.

How is DVT treated?
Our providers work with you to come up with the treatment plan that is best for your needs. Treatment may include blood thinners such as direct oral anticoagulants (DOACs) or heparin or warfarin, to prevent the blood clot from progressing or dislodging to the lungs. Minimally invasive procedures to remove the clot may be done or, in rare cases, a vena cava filter is placed to prevent embolisms from traveling to the lungs.

Can DVT be prevented?
Proactive protection, also called “prophylaxis,” for DVT is far easier than treating it after it has occurred. Frequent ambulation and simple leg exercise to help keep the blood moving, elevating the legs, or wearing compression stockings may ease the signs and symptoms of DVT.
