Thrombotic superficial phlebitis is a common peripheral vascular disease, often occurring in different diseases and in various disciplines of treatment, and although it is a minor disease, many patients experience twists and turns. Thrombotic superficial phlebitis can occur in all parts of the body, commonly in the extremities, followed by the chest and abdominal walls, with a few wandering episodes. The venous vessels in the body can be divided into superficial and deep veins according to their distribution. Superficial veins are those that travel in the subcutaneous tissue, also known as subcutaneous veins, and deep veins are those that travel in the deep surface of the deep fascia or in the body cavity. Some causes cause sudden redness, burning, pain, or pressure along the superficial veins, and the appearance of streaks or nodules. After the acute phase, the cords harden and local skin pigmentation occurs. Common causes of thrombotic superficial phlebitis Injury caused by intravenous hyperosmotic solutions irritating the venous lining, complicated by thrombosis; damage to the venous wall caused by intravenous indwelling cannulae, resulting in an inflammatory response. For the most common thrombotic superficial phlebitis of the lower extremities, it occurs due to venous blood stagnation, high blood lipids, high blood viscosity, slowed blood flow, and chronic infection of the skin in the foot and boot area due to nutritional changes, which causes the varicose veins to suffer from hypoxia and inflammatory damage, resulting in thrombotic superficial phlebitis. Chinese medicine classifies thrombotic superficial phlebitis as blood paralysis, pulse paralysis, swelling, and blood stasis. At the onset of the disease, the superficial vein is manifested as a stiff strip, which can have spontaneous pain, tenderness or pulling pain, generally known as “pulse paralysis”; along the superficial vein and its surrounding tissues suddenly develop red color, swelling, burning and pain, and after the redness and pain subsides, the local hard strip can be touched, and accompanied by pigmentation, or slight heat and light pain, which is a complication of varicose veins. If it is a complication of varicose veins, it is called “malignant veins”; if there is no history of varicose veins, it is called “blood stasis”. Prevention of recurrence Thrombophlebitis is prone to occur in winter and early spring cold season and needs special prevention. The reason why the elderly are prone to it is because the oxygen supply and blood supply of the lower limbs of the elderly are reduced, and the supply of nutrients to the skin is correspondingly reduced, and the skin is thinner. Venous blood stagnation, skin breakage, venous vascular damage, easy to induce thrombosis, resulting in thrombotic superficial phlebitis. Therefore, the prevention of thrombotic superficial phlebitis should be concerned, and attention should be paid to exercise the lower limbs to promote blood circulation, improve the blood supply and nutritional status of the lower limbs, and prevent the formation of thrombotic superficial phlebitis of the lower limbs. Diet and other aspects, you can eat more vegetarian food, green vegetables and fruits, avoid or less greasy food to prevent and control the high viscous state of blood. Vitamin E is an excellent antioxidant that helps maintain the normal function of nerves and muscle tissue and makes capillary walls more stable so that blood circulation, which was originally stagnant, can be restored to a smooth flow. Sunflower seeds are rich in vitamin E. They also have a high caloric content, which helps protect against cold weather. Women should reduce the use of oral contraceptives. Actively treat primary diseases, such as malignant tumors, diabetes, kidney disease, etc. can cause high viscosity and hypercoagulable state of blood. Also quit smoking strictly. The disease usually does not require hospitalization and should be treated with bed rest and elevation of the affected limb for 2 to 3 days. Under the guidance of a doctor, apply local heat physiotherapy or take a hot bath to reduce discomfort. Apply anti-inflammatory drugs and analgesics as prescribed by the doctor. Avoid the use of indwelling needles.
