Blood clots can wreak havoc on your veins, leading to symptoms that can last for years.
In addition, when a clot in the deep veins is very extensive or does not dissolve, it can result in a chronic or long-lasting condition called post-thrombotic syndrome (PTS), which causes chronic swelling and pain, discoloration of the affected arm or leg, skin ulcers, and other long-term complications.
A pulmonary embolism (PE) is a blood clot in the lungs, which can be serious and potentially lead to death. When left untreated, the mortality rate is up to 30% but when treated early, the mortality rate is 8%. Acute onset of pulmonary embolism can cause people to die suddenly 10% of the time.
During a surgical thrombectomy, a surgeon makes an incision into a blood vessel. The clot is removed, and the blood vessel is repaired. This restores blood flow. In some cases, a balloon or other device may be put in the blood vessel to help keep it open.
Although many people think walking around prevents blood clots, this is not true. Moving around and walking are important to keep you well and can help prevent things like pneumonia and bedsores. Walking by itself does not prevent clots.
For most people, walking or taking care of some housework are fine right after you find out you have DVT. It's also OK right after a pulmonary embolism. Your doctor may prescribe a blood thinner -- they may call it an anticoagulant -- and compression stockings.
“The added weight of the uterus further compresses the vein.†She suggests sleeping on your left side to improve circulation, and avoid sleeping on your back. "Elevate legs at end of the day and get a good pair of compression stockings if you get any swelling or varicose veins,†she says.
Anticoagulants also stop clots from getting bigger and prevent blood clots from moving. Anticoagulants do not destroy clots. Your body may naturally dissolve a clot, but sometimes clots do not completely disappear.
The authors concluded that walking exercise was safe in acute deep venous thrombosis (DVT) and may improve acute symptoms. Exercise training did not acutely increase leg symptoms of previous DVT and may prevent or improve post-thrombotic syndrome.
Approximately 60% of patients will recover from a leg DVT without any residual symptoms, 40% will have some degree of post-thrombotic syndrome, and 4% will have severe symptoms. The symptoms of post-thrombotic syndrome usually occur within the first 6 months, but can occur up 2 years after the clot.
In a thrombectomy, your doctor injects a contrast dye, which helps locate the clot using X-ray guidance. The clot can usually then be removed using a thin tube called a catheter, which is a long, flexible, hollow tube that is inserted through a vein in the groin or arm and threaded to the location of the blood clot.
The procedure takes approximately 2 to 3 hours. After the procedure, compression bandages are applied to the leg to reduce swelling. For up to 6 hours after the procedure, the patient may be asked to walk for 15 minutes, then rest for 45 minutes, and repeat.
DVT is most commonly treated with anticoagulants, also called blood thinners. These drugs don't break up existing blood clots, but they can prevent clots from getting bigger and reduce your risk of developing more clots. Blood thinners may be taken by mouth or given by IV or an injection under the skin.
Hospitalization is recommended for patients with massive DVT, with symptomatic pulmonary embolism, at high risk of anticoagulant bleeding, or with major comorbidity.
Overall 7-day survival was 74.8%; however, 96.2% of those with deep vein thrombosis were still alive at 7 days compared with only 59.1% of those with pulmonary embolism.
Several surgical options exist for treating DVT. Thrombolysis is a procedure used to dissolve and break the clot endovascularly. In this procedure, the vascular surgeon injects clot-dissolving drugs through a catheter directly into the clot.
You may need any of the following:
- Medicines may be given to treat pain, high cholesterol, high blood pressure, or diabetes.
- Antiplatelets , such as aspirin, help prevent blood clots. Take your antiplatelet medicine exactly as directed.
- Blood thinners help prevent blood clots.
- Take your medicine as directed.
If you are diagnosed with a venous clot, your doctor may refer you to a hematologist, a doctor who specializes in treating blood diseases.

Why is deep vein thrombosis an emergency? DVT is a blood clot in a vein located deep in the body. Veins in the legs are the most common place for a DVT to develop. A blood clot in leg veins is an emergency because it can lead to life-threatening complications.
