Thrombectomy

What is a Thrombectomy?

A thrombectomy is a minimally invasive procedure used to remove a blood clot (thrombus) from inside an artery or vein. When blood clots form in critical vessels, they can restrict or completely block blood flow, leading to serious complications including tissue damage, organ dysfunction, and life-threatening emergencies. Thrombectomy restores blood flow quickly by physically extracting the clot.

At Preferred Vascular Group, our vascular specialists perform catheter-based thrombectomy procedures using advanced imaging guidance to safely and effectively remove blood clots with minimal recovery time.

How Does a Thrombectomy Work?

Thrombectomy is performed using image-guided, catheter-based techniques that allow our physicians to reach and remove clots without major surgery.

During the Procedure

1. Access: The physician makes a small incision or puncture in the skin to access a blood vessel, typically in the groin or arm.
2. Catheter insertion: A thin catheter is inserted into the blood vessel and carefully guided through the vascular system to the location of the blood clot using fluoroscopy (continuous X-ray imaging).
3. Clot removal: Depending on the type and location of the clot, the physician may use one of several techniques:
   • Mechanical thrombectomy: A specialized device at the catheter tip physically breaks up and extracts the clot
   • Aspiration thrombectomy: Suction is applied through the catheter to pull the clot out of the vessel
   • Rheolytic thrombectomy: A high-pressure saline jet breaks up the clot while simultaneously suctioning the fragments
4. Additional treatment: After the clot is removed, the physician may perform angioplasty (balloon dilation) or place a stent if the underlying vessel is narrowed or damaged.
5. Completion: The catheter is removed and the access site is bandaged. In most cases, no stitches are required.

After the Procedure

• Blood flow is restored immediately upon clot removal
• Patients are monitored for several hours following the procedure
• Blood-thinning medications may be prescribed to prevent new clots from forming
• Most patients go home the same day or the following day

What Conditions Does Thrombectomy Treat?

Your doctor may recommend a thrombectomy for several conditions:

Deep Vein Thrombosis (DVT)

Deep vein thrombosis occurs when a blood clot forms in one of the deep veins, usually in the legs. DVT is a serious condition because the clot can break free and travel to the lungs, causing a potentially fatal pulmonary embolism. Thrombectomy can rapidly remove the clot and restore normal blood flow, particularly in cases of extensive DVT or when blood-thinning medications alone are insufficient.

Pulmonary Embolism (PE)

When a blood clot travels to the lungs and blocks one or more pulmonary arteries, it constitutes a medical emergency. In severe cases, catheter-directed thrombectomy can be used to remove or break up the clot and restore blood flow to the lungs.

Arterial Blood Clots

Blood clots can also form in arteries, blocking blood flow to vital organs and tissues. Arterial thrombectomy is used to restore blood flow in cases of:

• Acute limb ischemia: A sudden loss of blood flow to a leg or arm that threatens the viability of the limb
• Thrombosed dialysis access: Blood clots that block a dialysis graft or fistula, preventing hemodialysis treatment
• Mesenteric ischemia: Clots in the arteries supplying the intestines

Who is a Candidate for Thrombectomy?

Thrombectomy may be recommended when:

• A blood clot is large or extensive, posing a significant risk
• Blood-thinning medications (anticoagulants) cannot be used or are not working
• The clot is threatening organ function or limb viability
• There is a high risk of post-thrombotic syndrome from a large DVT
• Rapid clot removal is necessary to prevent permanent damage
• A dialysis access has clotted and needs urgent restoration

Your physician will evaluate the size, location, and age of the clot, along with your overall health, to determine whether thrombectomy is the best approach.

Benefits of Thrombectomy

• Immediate restoration of blood flow: The clot is physically removed, providing rapid results
• Minimally invasive: Performed through a small puncture using catheter-based techniques
• Reduces complications: Early clot removal can prevent long-term damage such as post-thrombotic syndrome [1]
• Preserves organ and limb function: Rapid treatment can save threatened tissues
• Can be combined with other treatments: Angioplasty, stenting, or thrombolytic medications can be used alongside thrombectomy
• Short recovery: Most patients resume normal activities within a few days

Potential Risks

As with any vascular procedure, thrombectomy carries some risks:

• Bleeding or bruising at the access site
• Damage to the blood vessel wall
• Clot fragments breaking loose (physicians take careful precautions to prevent this)
• Infection (rare)
• Recurrent clot formation
• Allergic reaction to contrast dye used during imaging

Your physician will discuss all potential risks and benefits with you before the procedure.

Recovery After Thrombectomy

• First 24-48 hours: Rest is recommended. Keep the access site clean and dry. Report any excessive bleeding, swelling, or fever to your care team.
• Medications: Blood thinners are typically prescribed for a period after the procedure to prevent new clots from forming.
• Activity: Light activities can usually be resumed within a few days. Your physician will provide specific guidance based on your procedure.
• Follow-up: Duplex ultrasound or other imaging may be performed to confirm successful clot removal and monitor for recurrence.
• Compression: Compression stockings may be recommended for DVT patients to reduce swelling and support recovery.
