What is a Deep Vein Thrombosis After Surgery?

What is Deep Vein Thrombosis after surgery? Deep vein thrombosis is a serious medical condition where a blood clot forms in a deep vein, typically in the legs, following a major procedure like a hip or knee replacement. If left untreated, a DVT can lead to a life-threatening pulmonary embolism (PE) or long-term vein damage. Understanding the symptoms—such as localized swelling, pain, or redness—and following a professional blood clot prevention plan is essential for a safe recovery. Dr. Cory Calendine and his team utilize advanced protocols, including blood thinners, compression therapy, and early mobility, to minimize DVT risks and ensure optimal patient safety after orthopedic surgery.

Deep vein thrombosis (DVT) occurs when a blood clot forms in one of the deep veins of the body. This can happen if a vein becomes damaged or if the blood flow within a vein slows down or stops. Two of the most common risk factors for the development of a DVT are an injury to your lower body and surgery that involves your hips or legs.

 

A DVT can have serious consequences. If a blood clot breaks free, it may travel through the bloodstream and block blood-flow to the lungs. Although rare, this complication (called a pulmonary embolism) can be fatal. Even if a blood clot does not break free, it may cause permanent damage to the valves in the vein. This damage can lead to long-term problems in the leg such as pain, swelling, and leg sores.

In many cases, DVT occurs without noticeable symptoms and can be very difficult to detect. For this reason, surgeons focus on preventing the development of DVT using different types of therapies, depending upon a patient’s risk and needs. Your surgeon will take steps to prevent DVT if you have a major fracture or are having lower extremity surgery—including total hip or knee replacement surgery.

Pulmonary Embolism

As mentioned above, one serious complication of DVT development after surgery is pulmonary embolism – a blood clot that breaks free and travels through the veins. This can happen right after the formation of the blood clot or it may happen days later. If the blood clot reaches the lungs, it can block the flow of blood to the lungs and heart. A pulmonary embolism is a serious medical emergency and can lead to death.

Preventing Deep Vein Thrombosis After Surgery | Joint Replacement

Deep vein thrombosis can develop after any major surgery. People who have surgery on the legs and hip are especially at risk. A pulmonary embolism is a blood clot that breaks-free and travels through the veins. If it reaches the lungs, it can block the flow of blood to the lungs and heart. A pulmonary embolism is a dangerous condition that can even lead to death.

Your surgeon will outline a program to help prevent the development of blood clots after surgery. The program may include periodic elevation of your legs, lower leg exercises to increase circulation, support stockings, and medication to thin your blood. This video provides additional information about DVT and its prevention.

It is important to work with your surgical care team prior to surgery to customize a prevention strategy best for each patient. If you have additional questions or concerns about the safety measures most important during hip and knee replacement, CONTACT our office today: (615) 791-2630

FREQUENTLY ASKED QUESTIONS

Common Questions From Readers

What are the warning signs of a blood clot (DVT) after surgery?
Common symptoms of deep vein thrombosis include persistent swelling in the calf, ankle, or foot; tenderness or cramping pain in the leg; and skin that feels warm to the touch or appears reddish/discolored. If you experience sudden shortness of breath or chest pain, seek emergency medical attention immediately, as these may be signs of a pulmonary embolism.
During surgeries like hip or knee replacements, the body’s natural response to “injury” is to initiate clotting to stop bleeding. Additionally, decreased mobility during and immediately after surgery slows down blood flow in the legs. This combination of factors makes it easier for a clot to form in the deep veins.
Preventative measures typically include a combination of “mechanical” and “chemical” therapies. This often involves the use of sequential compression devices (SCDs), compression stockings, early walking (ambulation), and anticoagulant medications (blood thinners) like aspirin or other prescription options tailored to your specific risk profile.
The highest risk period for developing a DVT is within the first few weeks following surgery. However, because every patient heals at a different rate, Dr. Calendine may recommend continuing preventative measures—such as blood-thinning medication or specific exercises—for several weeks until your mobility has fully returned to normal.
Yes, movement is one of the most effective ways to prevent clots. Simple exercises like “ankle pumps” (flexing your feet up and down) while in bed help keep blood circulating. Getting out of bed and walking as soon as possible after surgery is a critical part of the recovery protocol to ensure healthy blood flow and prevent stagnant blood from clotting.
