Prophylaxis of Deep Vein Thrombosis

Deep vein thrombosis (DVT) happens when a blood clot forms in a vein deep inside the body. Veins in the thigh, foot, and calf create a natural pumping system that helps flow blood back to the heart. But when an individual is immobile, blood circulation is decreased, and the risk of developing a blood clot goes up.

When a blood clot occurs, it can cause swelling and pain. If the clot breaks free and moves through the bloodstream, it is called an embolism. If the embolism gets stuck in the brain, lungs, heart, or other area, it can cause severe damage and even death.

External compression devices help stimulate the venous system and address the factors associated with clot formation. First, compression therapy helps increase the volume and velocity of flow from superficial veins up through the deep veins. This assists in decreasing venous stasis, blood pooling, and venous congestion. In addition, compression therapy helps decrease blood vessel distension and helps lower the risk of injury to the endothelium tissue. Finally, compression therapy enhances fibrinolysis, which assists in activating anti-clotting factors.

The National Institutes of Health shows that the most common causes for DVT are:

  • Bedrest for more than three days
  • Recent surgery, especially hip, knee, or female reproductive organ surgery
  • Pelvis or leg fractures
  • Smoking cigarettes
  • Taking estrogen or birth control pills
  • Giving birth in the last 6 months
  • Hypercoagulability
  • Heart failure
  • Obesity
  • Cancer
  • Sitting for long periods when travelling

Symptoms usually involve changes in a specific body part, including changes in skin color, increased warmth, pain and tenderness, and swelling. The prescribing physician should perform a physical exam and inquire about the patient’s medical history, particularly with respect to the contraindications for compression therapy: evidence of Congestive Heart Failure and suspicion of pre-existing Deep Vein Thrombosis. Specialized tests to determine the patient’s exact condition should be ordered. The prescriber will usually order either intermittent or sequential compression. We can assist you in selecting the best vascular pump to fill that prescription.

All of our devices strike a balance between patient comfort and efficacy. They will improve blood flow in the patient’s legs, reducing the risk for blood clots. They are applicable for use in most procedures, achieving the reliable outcomes when used for prevention in the Skilled Nursing Facility as well as before, during and after surgery. With the most complete product offering of any company worldwide, Vascular PRN has a full line of intermittent and sequential mechanical compression devices for the foot, calf, and full leg.
