Recanalization of Occluded Major Veins after Deep Vein Thrombosis

By Dr. Jose Almeida

October 12, 2015



Deep vein thrombosis (DVT) is a blood clot in a deep vein, most likely to develop in the leg. People who are over 60, overweight, or who sit for long periods are the most likely to develop DVT. The condition can be insidious; much of the time causing no symptoms. On the other hand, it can cause symptoms that resemble those of some other disorder.

The patient should call their doctor if they experience any of the following symptoms, especially if they appear suddenly:

• Pain, tenderness, or swelling in one or both legs
• Red or discolored skin on the leg
• A patch of warm skin on the leg
• Visible veins
• Tired legs

Sometimes a blood clot breaks free and travels elsewhere in the body. If it reaches the lungs, the result is a pulmonary embolism that can be fatal. While a pulmonary embolism may not cause any symptoms, it can also cause chest pain, extreme lightheadedness, shortness of breath or rapid breathing, and sudden coughing that might bring up blood. Anyone experiencing such symptoms needs to call 911 or get to an emergency room immediately.

What is Recanalization of Occluded Major Veins?

Recanalization is a two-part surgical procedure to reopen a blocked blood vessel.

The first part is done to widen the vein and involves angioplasty and stenting. During the angioplasty, the surgeon will insert a small balloon in the vein and inflate it, thus widening the vein. Afterwards, he will insert a stent or small mesh tube. The stent will support the vein walls and keep them open.

The doctor will begin the procedure by making a small incision in the skin that will serve as an access site. He will then insert a catheter into the site and use an X-ray machine to the blood clot. The surgeon will use catheters to deliver the angioplasty balloon and the stent.

The second part of the recanalization is called thrombolytic therapy. Here, medication is given to dissolve the clot. In some cases, the medicine is injected into the patient’s bloodstream. A catheter could also be used to deliver the medication directly to the clot. The tip of the catheter might also carry tools to assist with breaking up the clot.

What is My Next Step?

Recanalization could be recommended if the patient is at risk for developing a pulmonary embolism, has a DVT in their arm, or has large clots causing swelling and a lot of pain. The procedure is quick and effective, and it can even save the valves in the vein.
