Popliteal Aneurysm Repair

A popliteal aneurysm is a widening or bulging of the popliteal artery behind your knee. If left untreated, a popliteal aneurysm may cause blood clots that clog your artery or travel into your lower leg or foot, which can lead to the need for amputation.

The physicians at UPMC perform open and minimally invasive endovascular repairs of popliteal aneurysms to reduce your risk of complications.



What Is Popliteal Aneurysm Repair?

Popliteal aneurysm repair is a procedure to reduce the risk of complications related to a popliteal aneurysm, including rupture, blood clots, or blocked arteries in the lower leg or foot. Your doctor will use a stent or another type of graft to repair the aneurysm.

How serious is a popliteal aneurysm?

Although popliteal aneurysms do not usually cause symptoms, they are considered dangerous. They can cause blood clots that either clog your artery or travel down your artery and into your foot, which can lead to the need for amputation of the lower leg and/or foot.

Types of popliteal aneurysm repair

The physicians at UPMC perform open surgery and endovascular procedures to repair popliteal aneurysms. Your doctor will look at the size and placement of your aneurysm, as well as your overall health and physical condition, to determine which treatment option is right for you. Treatments include:

Endovascular repair for popliteal aneurysm

Endovascular repair is less invasive than open surgery. It uses a small, thin tube called a catheter to treat your popliteal aneurysm.

Endovascular treatment may be recommended for patients who are not good candidates for open surgery due to other health problems, including cardiac or pulmonary conditions.

Open surgical repair for popliteal aneurysm

During open surgery, your surgeon will cut your skin and tissue to reach the aneurysm directly. Your surgeon may use a vein graft or a prosthetic graft to bypass the aneurysm.

Why Would I Need Popliteal Aneurysm Repair?

You might need popliteal aneurysm repair if you are diagnosed with a popliteal aneurysm, especially if it contains a blood clot. Although popliteal aneurysms rarely rupture, they can cause blood clots that may block your artery or travel into your lower leg and foot.

Who’s a candidate for popliteal aneurysm repair?

You may be a candidate for popliteal aneurysm repair if your aneurysm is causing symptoms, is larger than 2 cm in diameter, or if you are at increased risk of related complications.

Endovascular treatment may be recommended for patients who are not good candidates for open surgery due to other health problems, including cardiac or pulmonary conditions.

What Are the Risks and Complications of Popliteal Aneurysm Repair?

Popliteal aneurysm repair is a safe and effective procedure. Complications are rare. However, like all medical procedures, it has some risks, including:

  • Blood clots that travel to the leg.
  • Injury to the nerves.
  • Problems with stents or bypass grafts.
  • Amputation.

What Should I Expect From Popliteal Aneurysm Repair?

Before: How to prepare for popliteal aneurysm repair

Your doctor will explain the popliteal aneurysm repair procedure to you and answer your questions. To prepare for the procedure, you should:

  • Tell your doctor if you are sensitive or allergic to any medications, iodine, latex, tape, or anesthetic agents (local and general).
  • Tell your doctor about all medications (prescription and over-the-counter) and herbal or other supplements you are taking.
  • Tell your doctor if you have heart valve disease. You may need to receive an antibiotic before the procedure.
  • Tell your doctor if you have a history of bleeding disorders or if you are taking any blood-thinning medications, aspirin, or other medications that affect blood clotting. You may need to stop some of the medications prior to the procedure.
  • Fast for a certain period of time prior to the procedure. Your doctor will tell you how long to fast (usually overnight).
  • Have any tests that your doctor recommends. For example, your doctor may request a blood test prior to the procedure to determine how long it takes your blood to clot.

On the day of your procedure, be sure to bring your photo ID and health insurance card(s). Leave valuables such as cash and jewelry at home. If you have a CPAP machine, please bring it with you.

You may need to stay in the hospital for several days after your procedure. You should bring toiletries, a robe, slippers, a cell phone and charger, medications, and a change of clothes. You should also arrange for someone to drive you home from the hospital after you are discharged.

How long does popliteal aneurysm repair take?

Your popliteal aneurysm repair procedure will take 1-2 hours or longer, depending on the size of your aneurysm and the type of procedure you are having.

During your popliteal aneurysm repair

Your doctor will look at the size and placement of your aneurysm, as well as your overall health and physical condition, to determine whether open surgery or an endovascular procedure is right for you.

Endovascular repair for popliteal aneurysm

During an endovascular repair, your doctor will:

  • Insert a long, flexible tube called a catheter into an artery through your groin or skin and thread the catheter to the aneurysm.
  • Insert an artificial tube called a stent graft through the catheter and expand it against the walls of the artery. The stent graft will help prevent a blood clot from moving to and blocking your leg and knee arteries. It also will prevent rupture of the aneurysm.

Open surgical repair for popliteal aneurysm

During an open repair, your surgeon will:

  • Cut your skin and tissue to reach the aneurysm directly.
  • Use a vein graft or a prosthetic graft to bypass the aneurysm, rerouting blood flow around it.
  • Open the sac of the aneurysm, remove the blood clot, and suture together the sac to prevent a recurrence.

Recovery after popliteal aneurysm repair

When the procedure is completed, you will be moved to recovery for observation and to address any issues you may have with pain. Endovascular procedures usually involve a quicker recovery and shorter hospital stay than open surgery. Your doctor will provide more information on your hospital stay and recovery.

What is the recovery time for popliteal aneurysm surgery?

You should ask your doctor when you can return to work and resume normal activities. Most people make a full recovery within 4-6 weeks. It is very important that you see your doctor for follow-up visits as recommended.

When to call your doctor about popliteal aneurysm repair complications

You should call your doctor if you are experiencing any unusual symptoms, including:

  • Pain, redness, bleeding, drainage, or increased swelling at the insertion or incision site.
  • Chest pain or shortness of breath.
  • Severe pain, coldness, numbness, swelling, or discoloration in the limb where the procedure was performed.
  • A fever of more than 100.0°F or chills.
  • Fainting, dizziness, or weakness.

If any of these symptoms are severe, you should dial 911 immediately.

What’s the prognosis of popliteal aneurysm repair?

Popliteal aneurysm repair can reduce your risk of complications, including amputation. Most people live a normal, active life after popliteal aneurysm repair.
