Deep Vein Thrombosis (DVT)
Deep vein thrombosis (DVT) is a condition that is associated with blood clotting in veins located deep within the body, most commonly venules in the legs . This is a condition that blocks a vein from being transported in the bloodstream from another place. Deep vein thrombosis occurs when the blood clot is formed and blocks the lower limb vein or pelvic vein. When the clot is peeled off into the circuit, it may lead to embolism lungs , causing death . This disease is common in the elderly, but young women are not immune, especially during the delivery period.
Symptoms of this disease are common in the legs or thighs, including: swelling , pain, redness of the extremities, especially the lower leg (below the legs), below the knee. It usually occurs on one leg, but can also affect both legs, increasing pain when flexing the legs. Pain can be increased by flexing the leg towards the knee. Severe cases may show ulcers in the calf and are more common if deep venous thrombosis is present in the femoral vein , in obese individuals or with deep vein thrombosis in the same leg.
There is, however, no symptom in the legs of the disease, which is only detected when the pulmonary embolism has been reported as a result of deep vein thrombosis. When pulmonary obstruction develops symptoms: shortness of breath, chest pain and syncope.
Deep vein thrombosis has symptoms that can be detected by imaging devices such as ultrasonography, which can help detect blood clots in the foot vein, with ultrasound Doppler technology that can help speed up the movement. intravenous venography after injection of contrast material will show that the substance is moving normally in the vein or blocked by thrombosis.
Some of the causes of deep vein thrombosis include:
Low Mobility :
For reasons such as illness, injury, occupational habits, habits of life , long journeys on airplanes , trains and cars. whose body is not or less active, It can increase the risk of deep vein thrombosis because when the body is not moving, the blood in the vein will slow down and increase the risk of blood clots.
Vasculitis, chemotherapy, traumatic injury to the vein increases the risk of this disease, whereas deep venous thrombosis can damage the wall. It increases the risk of another venous thrombosis in the blood vessels.
Medications containing estrogen when used to treat certain conditions such as cancer, treatment of premenopausal women have side effects that make the blood easier to clot, thereby increasing the risk. get this disease.
Due to heredity and diseases: Patients with cancer, heart failure, pregnancy, obesity, over 40 years of age, hereditary parents are factors that make the blood easier to clot. increased risk of deep vein thrombosis.
Clinical examination of patient, imaging of blood vessels using color Doppler, CT venography, MR venography, venogram., D-dimer test
The purpose of deep venous thromboembolism is to limit the size of the large blood clot, preventing them from breaking down into the lungs to avoid pulmonary embolism, to avoid complications and to recur. One or more of the following can be applied:
Use compression stockings to avoid software damage, prevent and reduce swelling, pain, and leg ulcers. This type of socks must be used every year or several months, after having had a hysterectomy, wear socks every day from early morning until bedtime.
Feet when Sleeping: When sleeping with knee joints feet and legs slightly higher than the calf, legs higher than the thigh to reduce pressure on the leg veins.
In order to prevent diseases, attention should be paid to the following measures:
- Increased mobility , especially after a prolonged surgery ,
- Postpartum women should avoid immobility or long stay
- People who are sedentary, should be motivated.
- People with coagulopathy should take anticoagulants as directed by their physician.
- If you have to go on the train, car, plane for long periods should note that create comfortable sitting position , just half an hour to stretch the legs, occasionally going back to the blood circulation .
Some effective measures include:
- Foot movement. Just sit for a long time, blood can clump in the legs, forming blood clots. So, every 1-2 hours, stand up and walk around, whether sitting at a desk or on a car or plane (stretching your legs while sitting is also effective).
- Have a healthy lifestyle: quit smoking . Smoking contributes to hardening of the arteries, thereby increasing the risk of blood clotting and drinking more water , as providing adequate fluid to the body can reduce the risk of blood clots.
- Maintain a healthy weight, exercise a healthy diet to promote cardiovascular health and regular physical activity.
- The oral contraceptive pill may increase the risk of deep vein thrombosis, should be considered and cautious.
- Know the signs of the disease to avoid, notice the pain, swelling, redness or change of colour on one leg or a burning sensation on the skin in the affected area.
