- A clot forms in a deep vein
- Blood flow is partially or completely blocked

When Is DVT Usually Managed Without Surgery?
- Most patients are treated with blood thinners (anticoagulants)
- Compression stockings and lifestyle changes
- Regular monitoring
When Is Surgery or Intervention Needed?
1. Large or Extensive Clots
- Clots involving major veins (e.g., thigh or pelvis)
- High risk of complications
- May require clot removal procedures
2. Failure of Medical Treatment
- Symptoms persist despite anticoagulants
- Clot continues to grow
3. Severe Symptoms (Phlegmasia)
- Extreme swelling and pain
- Reduced blood supply to the limb
- Risk of tissue damage or limb loss
4. Risk of Pulmonary Embolism
- Clot likely to travel to the lungs
- May require placement of an IVC filter
5. Recurrent DVT
- Repeated clot formation
- Underlying structural or clotting issues
6. Post-Thrombotic Syndrome
- Chronic pain, swelling, and skin changes
- In selected cases, intervention may be needed
Types of Surgical/Interventional Procedures
1. Thrombectomy
- Surgical removal of the clot
2. Catheter-Directed Thrombolysis
- Medication delivered directly to dissolve the clot
3. Inferior Vena Cava (IVC) Filter
- Prevents clots from reaching the lungs
4. Venous Stenting
- Keeps narrowed veins open

Final Thoughts
Surgery for DVT is not routine but becomes necessary in severe or complicated cases where medications are insufficient or complications arise. Early recognition and timely intervention are critical to prevent serious outcomes.
