Thrombectomy/Embolectomy

Thrombectomy and embolectomy are performed to remove blood clots or foreign bodies from a blood vessel (vein or artery). A blood clot is a clump of blood that has changed from a liquid to a gel-like or semisolid state. When a clot forms inside one of your veins, it won’t always dissolve on its own. A thrombus is usually a solid-mass stationary clot. An embolus is when part or all of that clot is dislodged and begins to travel through the circulatory system. Essentially, an embolus is a moving thrombus. Both of these clots can pose serious and even fatal risks, such as stroke, heart attack, gangrene, loss of limbs, and other serious heart problems.

Both of these procedures can be performed through using the following methods: non- invasive (no incisions required / small puncture / low to moderate sedation), minimally-invasive (small incisions of 2–3 inches long / general anesthesia), or through an open- surgical procedure (large incisions of 8-10 inches long / general anesthesia). The type of procedure chosen will vary according to your particular health condition.

How to prepare for the procedure

Before the procedure, your doctor and treatment team will explain to you what to expect before, during and after the procedure, and potential risks of the procedure. Other recommendations include:

Talk to your doctor about

  • All medications, herbal products and dietary supplements you are currently taking and ask for their recommendations about each.
  • Diabetes and how to adjust your medicine on the day of the procedure
  • Radiation exposure, especially for those that are pregnant
  • Any allergies to medicines, latex, tape, iodine, and anesthetic agents
  • Any history of bleeding disorders
  • Any implanted device (e.g. pacemaker or ICD)
  • Any body piercings on your chest or abdomen

Other suggestions

  • Eat a normal meal the evening before the procedure. However, do not eat, drink or chew anything after midnight before your procedure. If you must take medications, only take them with sips of water.
  • Leave all jewelry at home
  • Remove all makeup and nail polish
  • Wear comfortable clothing when you come to the hospital.
  • If you normally wear dentures, glasses, or hearing devices at home, plan to wear them during the procedure.

What to expect before the procedure

To determine whether you need either procedure, your doctor might perform a variety of tests, including:

Diagnostic tests and procedures

What to expect during the procedure

A thrombectomy usually takes 1 to 2 hours, but the preparation and recovery time may add several hours. The procedure is usually done in the catheterization lab. Check with your doctor about the details of your procedure. In general:

  • You will change into a hospital gown.
  • A nurse will start the intravenous (IV) line in your arm which will administer medications, fluids, and also give you a sedative that will help you relax.
  • Prior to starting the procedure, you will receive a local anesthetic to numb the catheter insertion site(s). Once the local anesthetic has taken effect, a catheter (which includes a specialized instrument at its tip) will be inserted into a blood vessel in the groin.
  • Once the catheter reaches its final destination, the specialized instrument helps break-up and remove the clots/foreign bodies.
  • After the procedure is complete, the catheter is removed and the insertion site(s) is closed with the use of a closure device (collagen) or sutures.

What to expect after the procedure

After this procedure, you will spend several hours in a recovery room. More often than not, you will be able to go home the same day. Other recommendations include:

General guidelines

  • A nurse will monitor your vital signs, the insertion site, circulation and sensation in the affected leg or arm.
  • After the procedure, you may need to take medicine for a short time to prevent blood clots.
  • Your doctor will give you instructions to follow during your recovery.
