A red streak of wandering superficial veins, known as wandering thrombophlebitis, is present in the superficial veins of the affected limb, which may fade after a few weeks. After some time they may appear again in a different or the same area, with pain and tenderness. It is one of the clinical manifestations of thrombophlebitis. The cause is mainly due to the patient’s lack of vital energy and the inability of the blood and Qi to reach the end of the blood vessels, resulting in the gradual necrosis of the fingers or toes due to lack of nutrition. The red streaks and wandering superficial veins are mainly manifested as limb ischemia, as well as wandering phlebitis, ischemic neuropathy and secondary infection due to ischemia. The main feature of superficial vein thrombosis is pain at the site of thrombosis and the appearance of a reddish, low-heated cord with tenderness and surrounding redness in the superficial vein. The disease is divided into two types: infectious and non-infectious. The infectious ones are mostly seen after acute infection, childbirth, pelvic or abdominal surgery, while the non-infectious ones are due to blood stagnation and are mostly seen in the veins of the posterior calf. Superficial varicose veins of the lower extremities: The vast majority are saphenous varicose veins (a few are small saphenous varicose veins or both small and large saphenous varicose veins), which are extremely common clinically, with approximately 25% of women and 15% of men worldwide suffering from these diseases, the onset of which is often associated with genetic factors and can be triggered by prolonged standing and heavy physical work. Local venous sclerosis: the appearance of striae or hard nodules along the superficial veins with redness, burning, pain or pressure, after the acute phase, the striae harden and local skin pigmentation, the above symptoms are seen in thrombotic superficial phlebitis.
