Is superficial vein thrombosis dangerous?

Superficial vein thrombosis is also relatively common. It often occurs in the patient's lower limbs and can cause some symptoms in the lower limbs. Usually, many people do not pay special attention to this situation, which often causes more serious symptoms and leads to deep vein thrombosis syndrome, such as swelling of the lower limbs, varicose veins, eczematous dermatitis, etc. In more severe cases, it can also cause pulmonary embolism in patients.

1. Thrombophlebitis:

There are two groups of veins in the lower limbs: deep and superficial. The deep veins run parallel to the arteries deep in the muscle; the superficial veins (great saphenous veins) run independently under the skin and merge into the femoral vein at the groin. The veins in the lower limbs are long, have many valves and branches, and are easily injured; or due to varicose veins, blood flow is slow and stagnant; coupled with high blood viscosity, platelet aggregation and many other factors, many factors promote the formation of venous thrombosis in the lower limbs and the complications of thrombophlebitis. Symptoms: swelling, fatigue, heaviness of the affected limb, difficulty walking, etc. Due to the obstruction and congestion of blood flow in the affected limb, tissue ischemia and hypoxia occur. Over time, the skin on the distal end of the lower limbs becomes malnourished, rough, flaky, and cracked, resembling rubber legs. Erysipelas infection and ulcer formation are common complications. Treatment: Within one week of the onset of severe acute thrombophlebitis, surgical thrombectomy can be considered to clear the blood flow. Chronic thrombophlebitis is suitable for blood circulation and anticoagulant treatment.

The sequelae of deep vein thrombosis is also called post-deep vein thrombosis syndrome. It refers to the recanalization of deep vein thrombosis. Damage to the valves in your veins. Venous blood flows backward, causing clinical manifestations such as distal venous hypertension and congestion. The affected limbs have varying degrees of swelling, heaviness and fatigue, which are aggravated after activities and worse in the morning and evening. There are varicose veins in the lower limbs and the skin pigmentation in the foot and boot area is calm. Eczematous dermatitis. Chronic ulcers, etc.

Pulmonary embolism is a common complication of lower extremity venous thrombosis. Blood clots that block the pulmonary artery often come from the veins of the lower limbs. The veins of the lower limbs and the pulmonary arteries belong to the same blood circulation pathway. After the lower limb vein thrombosis breaks off, it reaches the lungs along the blood flow, blocks the pulmonary artery, and causes pulmonary embolism. Warm reminder: Large emboli can stay in the pulmonary aorta or the bifurcation of the pulmonary artery, causing large-area pulmonary embolism, which is acute, severe and has a high mortality rate. Small emboli can reach the distal end of the pulmonary blood vessels, causing small areas of lung blockage, and the condition is mild and hidden. The manifestations of pulmonary embolism are nonspecific. Symptoms such as chest tightness, chest pain, palpitations, shortness of breath, and difficulty breathing are similar to myocardial infarction and are easily missed or misdiagnosed. After the above description of some of the dangers of venous thrombosis, I believe everyone has a certain understanding of which is more serious, so please pay more attention to it. Whether it is a serious illness or a minor one, it should be examined and treated as soon as possible. Everyone should pay more attention to the common sense knowledge of venous thrombosis to prevent it from happening. It will also be helpful to yourself if it really happens one day. I wish you all good health.
