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.
- 2,000,000 cases of DVT/PE are estimated to occur annually in the U.S.
- 600,000 patients are diagnosed with DVT/PE annually.
- 200,000 people yearly die of pulmonary embolism (PE).
- DVT/PE is the third leading cardiovascular killer behind heart attack and stroke.
- DVT/PE causes more people to die annually than breast cancer and AIDS combined.
Symptoms
Approximately 600,000 new DVT cases are diagnosed each year in the United States, and as many as 20 million patients have experienced DVT prior to it reoccurring.
Patient symptoms include pain, swelling, and discoloration.
It is important you do not ignore any signs or symptoms that may be related to DVT, especially if you have been treated for DVT before.
Treatment Options
The majority of patients diagnosed with DVT are treated with medication therapy alone. While this therapy reduces the risk of fatal Pulmonary Embolism and further blood clot from forming, the underlying blood clot may remain and result in permanent vein damage and the development of Post Thrombotic Syndrome.
Although pulmonary embolism is the most emergent concern, comprehensive care for a patient with DVT should consider all three potential consequences of the thrombus burden:
1. Pulmonary Embolism (PE)
- Prophylaxis with anticoagulants is very effective in preventing DVT/PE in patients at high risk.
- Anticoagulation of patients with confirmed DVT stops the progression of thrombus, but…
- Anticoagulants do not dissolve existing clot.
2. Quality of Life (QOL)
- DVT is much more than just a swollen leg. DVT Quality of Life patient scores are similar to patients with angina and chronic lung disease.
- In about one-third of DVT patients receiving anticoagulation, QOL deteriorates when measured four months after anticoagulation is initiated.
- Average QOL of all DVT patients on anticoagulation is poorer than population norms at four months.
3. Post Thrombotic Syndrome (PTS)
- PTS is a common long-term complication of DVT that can affect as many as 60-70% of people who have had a DVT, and can develop within two months of developing DVT.
- The socioeconomic and medical costs of managing patients with PTS and chronic venous disease are high.
- The direct cost of treatment of chronic venous disease is thought to exceed $300 million yearly in the US, and it is estimated that 2 million workdays are lost annually as a result of leg ulcers.
- In a Swedish study, the average overall direct medical cost of treatment of late complications of DVT was $4,659; venous ulcer development was the most costly complication.
Trellis Peripheral Infusion System
Isolated Thrombolysis is characterized by reduced lytic dosage, short treatment times, few complications, maintenance of valvular function and low costs.
The Trellis® Peripheral Infusion System is an advanced Isolated Thrombolysis catheter with two occluding balloons, drug infusion holes between the balloons, and mechanical drug dispersion capabilities. This pharmaco-mechanical combination enables physicians to provide focused treatment of thrombus within a targeted vessel. It has been shown to provide superior treatment of DVT compared to conventional methods of locally delivered thrombolysis.
