Venous Thrombectomy

Overview

Venous thrombectomy is a medical procedure used to remove a blood clot (thrombus) from a vein, most often in the legs. This treatment is commonly recommended for patients with deep vein thrombosis (DVT) when the clot is large, causing serious symptoms, or posing a risk of complications like pulmonary embolism. The goal is to restore normal blood flow and prevent long-term damage to the vein.

Why Venous Thrombectomy Treatment is Required?

• To treat deep vein thrombosis (DVT), especially when clots are large or life-threatening.
• When anticoagulation therapy (blood thinners) is not enough to dissolve the clot.
• To prevent complications such as pulmonary embolism or post-thrombotic syndrome.
• When there is impaired blood flow causing pain, swelling, or risk to limb health.
• In cases of failed conservative treatment or worsening symptoms despite medications.

Key Advantages of Venous Thrombectomy Treatment

• Quickly restores blood circulation by removing the clot.
• Helps prevent long-term complications like leg ulcers or chronic pain.
• Reduces swelling, tenderness, and discomfort associated with DVT.
• Often performed as a minimally invasive procedure, leading to faster recovery.
• May improve overall life expectancy, especially when done early.
• Offers a solution when anticoagulation is contraindicated or insufficient.

How Should You Prepare Yourself Before Venous Thrombectomy Treatment

• Medical Evaluation: Your doctor may recommend blood tests, ultrasound, or CT venography to assess the clot.
• Medication Review: Inform your doctor about all medications, especially blood thinners.
• Fasting Instructions: You may need to avoid eating or drinking for several hours before the procedure.
• Health Condition Discussion: Share your complete health history including any allergies, kidney issues, or heart conditions.
• Consent & Clarification: Understand the risks and benefits; ask your doctor any questions you may have.

How Venous Thrombectomy Treatment is Performed?

• Minimally Invasive Approach: A small incision is made near the clot site.
• Catheter Insertion: A thin tube (catheter) is inserted into the vein and guided to the clot.
• Clot Removal: Devices like suction, mechanical tools, or medication may be used to extract the clot.
• Imaging Guidance: Fluoroscopy or ultrasound helps guide the doctor during the procedure.
• Closure: The incision site is closed, and a bandage is applied.

The procedure usually takes 1 to 2 hours depending on the clot’s location and complexity.

What You Can Expect Before, During and After Procedure?

• Before the Procedure:
• You will undergo blood tests and imaging to locate and assess the clot.
• You will receive instructions on fasting and medication adjustments.
• During the Procedure:
• Local or general anesthesia will be used based on the case.
• The doctor will insert a catheter and remove the clot under imaging guidance.
• The procedure is typically painless due to anesthesia.
• After the Procedure:
• You will be monitored in recovery for a few hours or overnight.
• Medications may be prescribed to prevent further clots.
• You might need compression stockings to support healing.
• Most patients return to normal activities in a few days.

Risk and Potential Complications

• Bleeding at the puncture site.
• Infection though rare.
• Damage to the vein or surrounding tissues.
• Reformation of blood clots in the treated vein.
• Allergic reaction to contrast dye or anesthesia.
• Rarely, complications may affect the heart or lungs, especially if a piece of clot dislodges.

Results/Outcomes

• High success rate, especially in early intervention cases.
• Most patients experience immediate relief from swelling and pain.
• Reduced risk of post-thrombotic syndrome when done early.
• Many patients resume daily activities quickly with minimal discomfort.
• Life expectancy after venous thrombectomy improves significantly in patients who avoid long-term complications.
