Inferior vena cava (IVC) filters are small mesh devices that a surgeon can put in the inferior vena cava (a large vein), usually under local anesthetic. In other cases, the surgeon will divert blood flow or completely bypass the blocked artery. The procedure can involve directly accessing and unblocking an affected artery. Surgery for the effects of thrombosis will always be a medical emergency. The aim of treating a thrombus is to achieve the following quickly and effectively:ĭoctors typically recommend the following treatments to deal with the effects of thrombi: Surgery Thrombi in the liver, kidney, or brain may develop due to an inherited clotting disorder. This may be necessary in cases of repeated unexplained blood clots. It uses a radioactive substance called a radiotracer to reveal, on a scan, the flow of air and blood within the lungs.Ī doctor may request blood tests to check for a genetic blood clotting disorder.

A VQ scan: This is a nuclear imaging study.

MRI and CT scans: These scans create detailed images of organs, tissues, and blood vessels.

If the scan shows a slower-than-usual blood flow through the vein, a thrombus may be present. This dye makes the vein visible on some types of X-ray, such as a fluoroscopy.

Venography: For venography, a doctor will inject a dye into a vein in the affected leg.

If the result is normal and few risk factors are present, a person does not have a high risk of DVT. High levels of this substance may indicate the presence of DVT or another type of blood clot.

A D-dimer test: This test measures the levels of a substance in the blood that results from the breakdown of blood clots.

A duplex ultrasound uses sound waves to create images of the blood flowing through the arteries and veins.

Duplex ultrasound: This is the most common test for diagnosing DVT.

People who experience any of these symptoms should seek urgent medical attention.ĭVT can be a life threatening condition emboli can travel through the bloodstream before blocking arteries elsewhere in the body.ĭoctors use several different methods to diagnose the presence of a thrombus.

pain, swelling, and tenderness, usually in the calf.a limb that has become cold, pale, and painfulĪ thrombus in a vein, usually a deep vein in the leg, may lead to the following symptoms:.a sudden loss of strength in one arm or leg.People should seek emergency treatment if they experience any of the following symptoms: These conditions all require prompt medical attention. peripheral arterial limb ischemia, a condition that significantly reduces blood flow to the limbs.unstable angina, which is a type of chest pain.In the sections below, we cover the symptoms of arterial and venous thrombosis: Symptoms of arterial thrombosis This can lead to severe and even life threatening complications.Ī thrombus does not usually cause any symptoms until it blocks or heavily restricts the flow of blood.

The physical effects of a thrombus depend on its location in the body.īoth arterial and venous thrombosis can reduce or totally impede blood flow. Share on Pinterest Arterial thrombosis may lead to angina, a type of chest pain. When this happens in the deep veins of the leg, it is called deep vein thrombosis (DVT). When a thrombus occurs in a vein, it is called a venous thrombosis. When a thrombus forms in an artery, such as in the heart or brain, it is called an arterial thrombosis. It is especially dangerous if it reaches the heart, lungs, or brain (embolism).ĭoctors categorize thrombi based on the type of blood vessel in which they develop:

However, a thrombus can cause severe health problems, as it interrupts the function of a blood vessel.Ī section of a blood clot that breaks free from the thrombus and circulates in the bloodstream is called an embolus.Īn embolus moves through the vascular system until it lodges in a different part of the body.Īn embolus is a dangerous and potentially fatal complication of thrombosis. It quickly forms a plug that can reduce or prevent bleeding.
