Deep Vein Thrombosis Requires Attention To These Four Problems
- Jul 17, 2018 -

Deep vein thrombosis is a peripheral vascular disease with high morbidity, mortality and recurrence rate. It has become a worldwide public health problem. Here are 4 things you need to know about deep vein thrombosis.

1. Should the detection of deep vein thrombosis be treated immediately?

If deep vein thrombosis is detected, anticoagulant treatment should be determined according to the location and severity of the thrombus. Formal anticoagulant therapy is required in the following situations:

(1) all patients with DVT and PE;

(2) patients with DVT (distal isolated or proximal) or PE without inducement;

(3) patients with DVT or PE isolated at the distal end of lower limbs caused by temporary risk factors of non-surgery or surgery;

(4) patients with acute lower extremity isolated DVT with severe symptoms or risk factors for thrombosis progression, or patients with acute distal isolated DVT with acute lower limb detected thrombosis progression during dynamic imaging examination.

2. Deep vein thrombosis of lower extremity has no great influence on life, but can not be treated first?

If the patient thinks so, it's very dangerous. DVT clinical occult high, there is no clinical symptom in 80% of patients, so very easy to miss, but once the embolic loss, with embolus can blood to travel to the lungs, the blocking of pulmonary artery, cause fatal pulmonary embolism. Pulmonary embolism can range from asymptomatic to sudden death, with data showing that two-thirds of deaths can occur within one to two hours. Once pulmonary embolism occurs, the fatality rate is high and the rescue is difficult.

Therefore, the detection of DVT in the lower extremity should be treated as soon as possible regardless of the severity of the symptoms, except the remote isolated DVT without severe symptoms or risk factors of thrombosis progression. By the time you have symptoms, it's probably too late.

3. Acute deep vein thrombosis, how to treat?

For acute deep vein thrombosis, the first step is to stabilize the thrombus and prevent it from growing and falling off. The standard treatment in the acute phase is anticoagulant therapy, which can be subcutaneous injection of low molecular weight heparin or oral anticoagulant drugs. Treatment must be as early as possible, as long as possible, and in sufficient quantity.

Why should be in bed with acute DVT?

The lower leg is the "second heart" of the human body. When the thrombus in the acute phase is not stable, the lower leg muscles may squeeze the blood vessels, leading to thrombus shedding and pulmonary embolism. So stay absolutely in bed during the acute phase, and try to get out of bed only when the clot is stable.
