The relationship between deep vein thrombosis and pulmonary embolism
1. What is Deep Vein Thrombosis?
Deep vein thrombosis is a common disease, common today with a high mortality rate. The disease causes many serious complications with great treatment costs. In Vietnam, according to the INCIMEDI study, deep vein thrombosis is not uncommon in our country, although there are no exact data. The study found that, based on Duplex ultrasound, up to 22% of hospitalized medical patients with deep vein thrombosis were asymptomatic. The elderly are often missed at diagnosis, or patients are diagnosed only after death.
If patients with deep vein thrombosis are diagnosed and treated early, it will help increase survival rates and limit potentially dangerous complications.
2. Signs and causes of deep vein thrombosis
The appearance of blood clots leads to increased production of elastic fibers in the endothelial layer of blood vessels, causing blood vessels to swell, causing the endothelium to thicken at the site of thrombosis, leading to narrowing of the lumen, the risk of occlusion. veins increase over time. In addition, patients with deep vein thrombosis were 6 times more likely to develop varicose veins than those without the disease. Therefore, clinically, symptoms of venous insufficiency may appear in patients with venous thrombosis.
There are many causes of deep vein thrombosis, such as surgery, trauma or an immune system reaction that can all cause the disease. Besides, the formation of blood clots can stem from other major causes, including genetic disorders, hormonal changes in the body, sitting for a long time,...
Coagulation helps stop bleeding after a wound, which is a normal body process, such as a cut in the skin. Blood clots can form in a vein with the following conditions:
Blood flows too slowly The lining of the vein is damaged Disturbances in the blood lead to easier clotting. The formation of blood clots in the deep veins causes blood circulation to slow down, the volume of blood in the veins increases. It is very dangerous if a piece of the blood clot breaks off and travels through the blood vessels to the lungs. This condition, called pulmonary embolism, carries a high risk of death. Nearly one-third of people with deep vein thrombosis are at risk of developing a pulmonary embolism. Therefore, in order to prevent pulmonary embolism, it is imperative to screen, detect and treat deep vein thrombosis in time.
3. The relationship between deep vein thrombosis and pulmonary embolism
