Mechanical Thrombectomy

Mechanical thrombectomy is an emergency treatment that removes a blood clot from a blocked brain artery to help restore blood flow during certain strokes.

  • Stroke & Cerebrovascular Disorders

    We have decades of experience caring for patients with stroke & cerebrovascular disorders, pioneering minimally invasive treatments and leading research for new treatments to improve patient outcomes.

What Is a Mechanical Thrombectomy?

A mechanical thrombectomy is a minimally invasive treatment used to remove a blood clot from an artery in the brain. It is most often used for certain ischemic strokes, which happen when a clot blocks blood flow to part of the brain. During the procedure, a physician guides a thin tube called a catheter through a blood vessel, usually starting in the groin or wrist, to reach the blockage and remove it.

This treatment is designed to reopen the artery as quickly as possible. Restoring blood flow may help limit brain injury and reduce the long-term effects of stroke. Not every person with stroke is a candidate, so the care team uses brain imaging and other tests to decide whether mechanical thrombectomy may help.

Why Choose Baptist Health?

Baptist Health Brain & Spine Care provides care through a coordinated team approach for people with complex brain and blood vessel conditions. For patients being evaluated for mechanical thrombectomy, fast assessment, advanced imaging and collaboration across Stroke care can support timely treatment decisions.

Because mechanical thrombectomy is typically performed in an urgent setting, patients may benefit from care that is organized, efficient and tailored to the type of blockage, the part of the brain involved and the person’s overall health.

Why Choose Baptist Health?

How It Works

Mechanical thrombectomy uses image guidance to help a physician move a catheter through the blood vessels to the blocked artery in the brain. Small devices can then be used to capture or suction out the clot. The goal is to reopen the artery and improve blood flow to brain tissue at risk.

Who May Benefit

A mechanical thrombectomy may be considered for some people with an ischemic stroke caused by a large vessel blockage. In general, it may be recommended when:

  • Symptoms started recently or the person was last known well within a treatment window determined by imaging and clinical evaluation
  • Brain imaging suggests there may be salvageable brain tissue
  • Symptoms are significant or disabling
  • The blocked artery can be reached safely with endovascular treatment

A full medical evaluation is needed to decide whether this treatment is appropriate.

Benefits and Risks

Possible benefits of mechanical thrombectomy include:

  • Removing the clot without open surgery
  • Restoring blood flow to part of the brain
  • Potentially reducing stroke-related disability in selected patients

Possible risks depend on the patient’s condition and the procedure itself, but may include:

  • Bleeding, including bleeding in the brain
  • Damage to a blood vessel
  • The clot not being fully removed
  • Reaction to contrast dye or other procedure-related complications

The care team reviews expected benefits and possible risks based on the patient’s imaging results, timing and overall health.

What to Expect

  • Because mechanical thrombectomy is an emergency treatment, preparation usually happens quickly. The care team may perform a neurologic exam, blood tests and brain imaging such as CT, CTA or MRI scans to confirm the type of stroke and locate the blockage. The team also reviews medicines, allergies and other medical conditions when possible.

  • The procedure is usually performed in a specialized procedure room using imaging for guidance. A physician places a catheter into a blood vessel and carefully guides it to the blocked artery. Devices may be used to remove the clot and restore blood flow. Patients may receive sedation or anesthesia depending on the situation.

  • After the procedure, patients are monitored closely for changes in neurological function, blood pressure and signs of complications. Follow-up imaging may be needed. Recovery and next steps depend on how much brain tissue was affected, how quickly blood flow was restored and whether rehabilitation is needed.

Recovery

Recovery after a mechanical thrombectomy varies. Some people improve quickly, while others need ongoing hospital care and rehabilitation. Recovery may include physical therapy, occupational therapy, speech therapy, follow-up imaging and treatment to help lower the risk of another stroke. The care plan depends on the cause of the stroke and the person’s needs.

Frequently Asked Questions

  • Mechanical thrombectomy is used to treat certain ischemic strokes caused by a blocked artery in the brain. It aims to remove the clot and restore blood flow as quickly as possible.

  • No. Mechanical thrombectomy physically removes the clot with a catheter-based procedure. Clot-dissolving medicine, such as thrombolysis, uses medication to break up the clot. Some patients may receive one treatment, while others may receive both.

  • Only some patients are candidates. The care team looks at the type of stroke, the location of the blockage, brain imaging results, symptom severity, timing and overall health before recommending treatment.

  • This treatment is time-sensitive. In general, it is most effective when performed as quickly as possible after stroke symptoms begin, although some patients may still qualify later based on imaging and clinical evaluation.

  • No. Mechanical thrombectomy is considered minimally invasive. The physician reaches the clot through a blood vessel using a catheter instead of making an opening in the skull.

  • Risks can include bleeding, blood vessel injury, reaction to contrast dye or incomplete clot removal. The care team explains the risks in the context of the patient’s condition and the urgency of treating the stroke.

  • Patients usually stay in the hospital for close monitoring. Follow-up care may include additional testing, stroke prevention treatment and rehabilitation services, depending on symptoms and recovery.

  • Possibly. Even when blood flow is restored, some patients need rehabilitation to help with movement, speech, swallowing or daily activities. Recovery depends on the severity of the stroke and how quickly treatment was given.
