Thrombectomy: What It Is and What to Expect

What kind of doctor provides Thrombectomy?
A thrombectomy is done by a specially trained doctor, such as an interventional radiologist (a doctor who treats blood vessels with thin tubes), a vascular surgeon, or a brain blood vessel specialist for stroke. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What it is
For stroke, doctors use a mechanical thrombectomy. It removes a clot in eligible patients with a large vessel occlusion, or LVO.
For a clot in the lung or leg, doctors may use catheter-assisted blood clot removal. This uses a flexible tube called a catheter to reach the clot.
Why a doctor might recommend it
An ischemic stroke is caused by a blood clot that blocks a blood vessel in the brain.
The urgent treatment for ischemic stroke is clot removal. Doctors can do this with medicine and mechanical treatments.
For a blood clot in a vein, such as in the leg or lung, the provider will likely give medicine first. A surgical procedure may be needed if you cannot take the medicine.
How to prepare
For a stroke, time matters. Immediate treatment may save someone's life and increase the chances for successful rehabilitation and recovery.
What happens during it
For stroke, doctors use a wire-cage device called a stent retriever. They thread a catheter through an artery in the groin up to the blocked artery in the brain. The stent opens and grabs the clot. Special suction tubes may also remove the clot.
For a clot in the lung or leg, the provider can insert a tool in the catheter to break up the clot or to deliver medicine. Usually, you will get medicine to make you unconscious and unable to feel pain for this procedure.
Recovery
After a stroke, hospital care focuses on many parts of recovery, including:
- Watching for and preventing complications.
- Finding the cause of the stroke.
- Starting treatment to prevent more strokes.
- Starting recovery and figuring out rehabilitation needs.
Stroke rehabilitation can help you relearn skills you lost because of the damage.
Call 911 right away if you think that you or someone else is having a stroke. Signs of a stroke often happen quickly. They include sudden numbness or weakness of the face, arm, or leg, especially on one side of the body. They also include sudden confusion, trouble speaking, or trouble understanding speech. Sudden trouble seeing in one or both eyes is another sign. Sudden trouble walking, dizziness, or loss of balance are signs too. So is a sudden severe headache with no known cause. Also call 911 for chest pain or discomfort lasting two minutes or more, trouble breathing, fainting, or bleeding that will not stop.
Risks and side effects
Medicines that dissolve blood clots are called thrombolytics. They can cause sudden bleeding. For that reason, they are used only for serious and potentially life-threatening events, such as pulmonary embolism.
Ask your care team which risks apply to your own procedure.
Who performs it
A specially trained doctor, such as an interventional radiologist, a vascular surgeon, or a brain blood vessel specialist for stroke, does a thrombectomy.
Common questions
How soon should a thrombectomy for stroke be done?
It is usually done within six hours of the start of stroke symptoms. It can be done up to 24 hours after symptoms begin if imaging tests show undamaged brain tissue.
Is a thrombectomy the same as clot-dissolving medicine?
No. Alteplase and tenecteplase work by dissolving the clot. A mechanical thrombectomy removes the clot in eligible patients.
Will I be awake for catheter-assisted clot removal?
Usually not. You will usually get medicine to make you unconscious and unable to feel pain.
How does a direct primary care or concierge doctor fit in?
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. They can help you manage your overall health and follow your treatment plan after a clot or stroke. They do not perform the thrombectomy. They would refer you to a specialist and stay involved before and after to coordinate your care.
