What is Deep Vein Thrombosis?

Deep Vein Thrombosis (DVT) is a blood disorder resulting from the formation of a blood clot (thrombus) inside a deep vein of the leg, commonly located in the calf or thigh. DVT occurs when the blood clot either partially or completely blocks the flow of blood in the vein. Symptoms include pain, swelling, and discoloration. This often happens after trauma or surgery, especially orthopedic surgery.

DVT: Common Symptoms

Common symptoms of DVT include:

  • Pain or tenderness in one or both legs, which may occur only while standing or walking
  • Swelling in one or both legs
  • Warmth in the skin of the affected leg
  • Red or discolored skin in the affected leg
  • Visible surface veins
  • Leg fatigue


How is Deep Vein Thrombosis Treated?

NYC Surgical Associates treats DVT with the Trellis procedure – a groundbreaking treatment that our surgeons specialize in. The procedure uses mechanical forces and “clot busting” medication to remove deep vein clots that previously could not be reached without a major procedure.

The animation below shows how the Trellis procedure is performed.

The Trellis procedure is used in a select group of patients to remove life-threatening deep vein clots that would otherwise be treated with less effective and more invasive techniques, which often require long periods of blood thinning medication.

Using X-Ray guidance, our doctors place the Trellis catheter through the clot to be treated. Balloons are inflated on either side of the clot to localize the treatment. Clot busting medication is then delivered through the catheter in the affected vessel and the catheter spins, mixing the “clot busting” drug into the blood clot. After about 10 minutes, our doctors may aspirate the drug and the dissolved portion of the deep vein clot through the Trellis catheter. From there, a repeat X-Ray study is done to ensure full success of treatment prior to removal of the catheter.
