The above symptoms are seen in thrombotic superficial phlebitis when strips or hard nodules appear along the superficial veins with redness, burning, pain or pressure, and after the acute phase, the cords become hard and local skin pigmentation. The above symptoms are seen in thrombotic superficial phlebitis. The clinical disease is multi-infarct and common. It can develop in both men and women, and is more common in young adults. Superficial thrombophlebitis can occur in all parts of the body, usually in the extremities, followed by the chest and abdominal walls, with a few wandering episodes. The clinical features are sudden onset of redness, burning, pain, or pressure along the superficial veins and the appearance of striae or hard nodules. After the acute phase, the cords harden and local skin pigmentation occurs. It belongs to the category of blood paralysis, vein paralysis, swelling and blood stasis in Chinese medicine. At the onset, the superficial vein is a hard cords and may have spontaneous pain. Tenderness or pulling pain is generally called “pulse paralysis”. Examination of superficial thrombophlebitis: 1. Leukocyte count up to 20×109/L, pathological examination for suspected patients. 2.Venogram shows narrowing or blockage of deep veins in the affected limbs. 3.Ultrasound examination shows local varicose veins with obvious widening of the diameter, uneven thickening of the wall, echogenic enhancement of the wall, low and isoechoic masses visible in the lumen, no deformation of the lumen under pressure of the probe, no obvious blood flow signal in the lesion area, subcutaneous tissue edema. 4, superficial phlebitis due to venous placement, blood culture is feasible, 2 times positive for the same strain, which can be used as evidence of infection. 5.Gastrointestinal function examination, for wandering thrombophlebitis of unknown cause, gastrointestinal function examination should be performed to exclude the possibility of malignancy. 6.Two-way Doppler flow imaging examination: it can detect the blood clot in superficial veins and the extent of blood clot spread. 7.Venogram examination, usually not necessary to do venogram, sometimes to exclude deep vein thrombosis, can be carried out.
