Lower extremity edema, venous ulceration due to deep vein thrombosis

News, Entertaiment

Deep vein thrombosis is a serious and increasingly common disease.

Ho Chi Minh City University of Medicine and Pharmacy Hospital has just organized a consultation program “Cardiovascular rhythm” with the topic “Low extremity edema, venous ulceration due to deep vein thrombosis” with the companionship of MSc. Le Phi Long, Deputy Head of Thoracic – Vascular Department and Doctor of CKI. Nguyen Duc Chinh – Department of Interventional Cardiology.

At the program, experts said, about 80% of patients with deep vein thrombosis have no symptoms until a more serious complication is pulmonary embolism. In the absence of pulmonary embolism complications, up to 20-50% of patients later develop post-thrombotic syndrome with lower extremity edema, venous ulcers causing pain and limitation of movement.

Recognizing lower extremity edema, venous ulceration due to deep vein thrombosis
Thrombosis is the formation of a pathological blood clot in the blood vessels or chambers of the heart in a living person Health. These clots can cause local embolism or migrate with the incoming blood stream to obstruct the distal blood vessels.

Veins are blood vessels in the circulatory system that carry blood from capillaries with low oxygen levels back to the heart. Thrombosis in the venous system, deep vein thrombosis causing skin ulcers in the lower area, venous location with thrombosis, leg pain, prolonged edema.

This condition will cause the patient to live in pain, severely affecting the ability to walk. In the long term, blood clots in the lower extremities can travel to the pulmonary arteries, causing pulmonary embolism, acute respiratory failure, and even sudden death.

Subjects prone to venous thromboembolism are people with hypercoagulable state, trauma patients, recent surgery, prolonged lying down, infection, etc. Besides, there are other factors in life such as: sitting for a long time. Standing for long periods of time also increases the risk factors for disease.

According to BS CKI. Nguyen Duc Chinh, 17% of factors related to hypercoagulability are genetic and the remaining 80% are related to life activities and diseases. In patients with pre-existing disease, approximately 50% will progress to post-thrombotic disease and 5-10% will develop venous ulceration.

In the RIETE study, a multicenter study in 27 countries (including Vietnam) with about 120,000 patients participating, the rate of leg ulcers after 1, 2 and 3 years was 2.7%, 4, respectively. 3% and 7.1%. The risk of post-thrombotic ulcers increased 5.5 times in the presence of venous thrombosis, 2.3 times in the presence of diabetes, 3.2 times in the presence of varicose veins, 2.5 times in the male and increased 2 times in obese people.

Methods to treat lower extremity edema, venous ulcers caused by deep vein thrombosis
In terms of treatment methods, the University of Medicine and Pharmacy Hospital in Ho Chi Minh City is usually divided into three groups. The first is the lifestyle treatment group, these subjects need to limit standing for a long time, sit for a long time, increase movement, in addition, need a combination of supportive measures such as wearing pressure socks or using compression bandages to help prevent pain. reduce venous stasis and thrombosis in the future.

The second group is the drug therapy group, one of the main treatment drugs is anticoagulants, combined with drugs that increase venous activity. The third group is the surgical intervention group.

Lower extremity edema, venous ulcers due to deep vein thrombosis often occur in women during pregnancy and people undergoing cancer treatment, basically the treatment method is the same as above. However, according to BS CKI. Nguyen Duc Chinh should have some notes such as: Pregnant women in the first 3 months of pregnancy have a much higher risk of coagulation, if the patient has never been treated, consider using anticoagulants. , visit regularly. Cancer patients who are taking chemotherapy drugs, radiation therapy, especially terminal cancer patients also need to be closely monitored and follow the doctor’s instructions.

According to MSc BS. According to Le Phi Long, the risk of venous thromboembolism recurrence can be completely prevented if these are transient risk factors, while those are hereditary or difficult to prevent risk factors. High recurrence needs to be re-examined, take medicine and follow the instructions of the hospital.

“Prevention is better than cure”, measures to prevent venous thrombosis such as: change in lifestyle, early post-surgery exercise, exercise, physical therapy; wear preventive pressure socks; slightly interrupted socks; anticoagulation or intravenous mesh filtration. For patients using anticoagulants, it is necessary to pay attention to the correct dosage in accordance with the body’s condition, according to the instructions of the doctor, and at the same time, change the lifestyle and exercise the body.
