local venous sclerod
Introduction
Introduction A filament or induration occurs along the superficial vein, accompanied by redness, burning, pain or tenderness. After the acute phase, the cord is hardened and the local skin is pigmented. The above symptoms are seen in thrombotic superficial phlebitis.
Cause
Cause
1 superficial phlebitis caused by chemical stimulation, intravenous injection of various irritating solutions, such as: hypertonic glucose solution, various antibiotics, hydrocarbonating agents, organic iodine solution, etc., can be injected into the superficial vein The chemical stimuli cause a rapid formation of thrombosis in a wide range of lesions, followed by a significant inflammatory response.
2 catheter for continuous infusion often causes direct damage to the vein wall to thrombosis, and rapid inflammatory response. It is common in critically ill patients such as extensive burns, severe trauma and major surgery.
3 When the varicose veins of the lower extremities belong to the genus of the saphenous vein or the small saphenous vein, the venous blood stasis lags the skin of the foot. Often due to nutritional changes, chronic infection can cause venous venous inflammation caused by hypoxia and inflammatory damage in varicose veins.

Clinically common, common diseases. Both men and women can develop the disease, which is more common in young adults. Thrombotic superficial phlebitis can occur in various parts of the body, usually in the limbs, followed by the chest and abdomen wall, and a small number of migratory attacks.
The clinical features are: sudden swelling, burning, pain or tenderness along the superficial vein, and a strip or induration. After the acute phase, the cords become hard and the local skin is pigmented. It belongs to the category of blood stasis, pulse, swelling and blood stasis of Chinese medicine. At the time of onset, the superficial vein is a hard cord that can have spontaneous pain. Touching or pulling pain, commonly referred to as "pulse".
Diagnosis
Differential diagnosis
Due to the different etiology, pathology and clinical features, the limb, chest and abdominal wall thrombotic superficial phlebitis is called benign thrombophlebitis. Intermittent, recurrent thrombotic superficial phlebitis is called migratory thrombophlebitis.
1. Benign thrombotic superficial phlebitis occurs in the lower extremities. It is often seen as red, swollen, hot, and painful along the vein. When the redness and swelling disappear, a brown strip appears, and the cord can be touched under it. Occurred in the chest and abdomen wall and upper limbs, most of the pain can touch the cord-like hard objects. Combined with blood transfusion, infusion, trauma, and a history of traction injury, the diagnosis can be confirmed.
2, migratory thrombophlebitis, according to the characteristics of recurrence and migration of thrombotic superficial phlebitis, the diagnosis is not difficult.
3, extremity thrombotic superficial phlebitis, the main blood test routine, suppurative superficial phlebitis, white blood cell count up to 20 × 109 / L, the diagnosis of suspected patients feasible pathological examination. Young adults, with varicose veins, have recently been locally traumatized or affected by wind and cold, or have a history of intravenous infusion or a history of venous injury. The superficial veins of the lower extremities or upper extremities, suddenly appear red, swollen, hot, painful, strips or nodules along the direction of the veins. Mild fever can occur in the whole body, and white blood cells are slightly elevated. If there is a venous indwelling catheter, sudden chills, fever, increased white blood cells, local swelling, and withdrawal of the venous catheter should be considered with pus.
4, chest and abdominal wall thrombosis superficial phlebitis, this disease occurs mostly in young, middle-aged people, chest has pulled and twisted and other trauma or surgical history. Spontaneous pain in the chest and abdomen wall, which can be seen as a linear or tortuous vein, which is painful, hard and tough, and has a cord-like or nodular shape. When the upper limb of the affected side is happy or the chest and abdomen wall is overextended, the pain is aggravated, and along the line of the strip, a shallow groove with a bow-string depression appears.
