Wandering superficial thrombophlebitis Wandering superficial thrombophlebitis is a recurrent superficial phlebitis, superficial venous thrombosis, which can occur in different parts of the body, with the lower extremities being the most common. It is often the early symptom of thrombo-occlusive vasculitis and cancer. 1, the etiology pathology: wandering thrombotic superficial phlebitis of the good factors for infection, allergies, metabolic diseases, hypercoagulable state, etc.. The disease occurs in young and middle-aged men, but is closely related to two diseases. (1) Wandering thrombotic superficial phlebitis is often an early physical manifestation of visceral cancer, and its primary cancer sites involve the stomach, pancreas, lung, gallbladder and other organs, especially the cancer of the body tail of the pancreas is most closely related, so the detection of wandering thrombotic superficial phlebitis should be examined for cancer accordingly. ②Wandering thrombotic superficial phlebitis may be an early manifestation of thrombo-occlusive vasculitis. Given that the majority of patients are young and middle-aged males who present with wandering superficial thrombophlebitis at the outset and subsequently often develop thrombo-occlusive vasculitis, it is often assumed that wandering superficial thrombophlebitis is an evolution of thrombo-occlusive vasculitis and is a clinical manifestation of one stage in the overall course of the disease. Thrombo-occlusive vasculitis is associated with wandering superficial thrombophlebitis in 50% of cases. Wandering superficial thrombophlebitis mainly affects small and medium superficial veins with thrombosis and reocclusion by mechanization of the inflammatory thrombus in the vein wall. The inflammation of the vein wall contains giant cells. None of the tissues adjacent to the involved vessels have a significant inflammatory response. Multiple or generalized superficial venous involvement may sometimes be accompanied by visceral venous involvement. According to Chinese medicine, wandering superficial thrombophlebitis is mainly due to damp-heat accumulation and stagnation of blood stasis in the veins, and is often a symptom of visceral diseases. 2, clinical manifestations and signs: Wandering thrombotic superficial phlebitis occurs in the lower extremities, often in an area suddenly appearing strips or mesh-like objects, redness, swelling, pressure pain, and sometimes can be found in several parts of the body at the same time. The clinical manifestations at the onset of the disease are not significantly different from those of general thrombotic superficial phlebitis. Since the lesions involve small and medium-sized superficial veins, the lumen is clogged with thrombus, but it does not cause obstruction of venous blood return, and there is no swelling of the limbs. Wandering superficial thrombophlebitis has a mild systemic reaction, with some patients having only mild fever, and is characterized by intermittent, wandering, and alternating occurrences throughout the body, with each episode lasting mostly 2-4 weeks, and then subsiding on its own. After an interval of several weeks or years, superficial veins in other parts of the body can have the same episodes again and again, and the pigmentation and cords left after long-term episodes can cover the whole body. The systemic reaction of the disease is mild, there may be mild fever, in a region or on one limb, sudden appearance of linear or reticular red swollen cords, accompanied by pain and pressure pain, cords have obvious inflammatory reaction, after 2-4 weeks, it will subside on its own, other parts reappear, after long-term lesions, star pattern pigmentation and cords, covering the limbs or circumference. 3, auxiliary examination: blood routine shows slightly higher white blood cell count and faster blood sedimentation. At the same time, routine examination of stomach, liver, spleen, pancreas, kidney and intestine should be performed to exclude underlying diseases, and pathological examination of enlarged lymph nodes and examination of blood supply of limb arteries (arteriography if necessary) should be performed to prove whether there is thrombo-occlusive vasculitis. 4, identification and treatment: because of dampness and toxicity into the Ying and Wei, stagnant in the meridians, containment into disease, so the epidermis red hot, burning pain, still “the pulse in the blood flow is not smooth, then the blood veins condense and pain. Treatment should be based on clearing heat and relieving dampness and detoxifying the toxin, and the formula is based on Si Miao Yong An Tang plus or minus: Jin Yin Hua, Xuan Shen, Angelica, Boswellia, Myrrh, White Lentil, Chen Pi, Atractylodes, Licorice, etc. If heat is prevalent, add Da Qing Ye, Ban Lan Gen, Di Ding, Dandelion, Dan Pi, etc. For external treatment, fresh amaranth can be used, pounded and applied externally to the affected area twice a day, or the alum can be washed in boiling water and then fumigated while hot, 2-3 times a day. 5, general treatment: acute treatment, mainly symptomatic treatment, such as local application of hot compresses, the affected limb wrapped elastic stockings or elastic bandages, etc., can also take kotexone, 3 times a day, 5-10mg each time. enteric aspirin, 3 times a day, 20mg each time, has anti-inflammatory and analgesic effect. If at the same time visceral venous involvement is suspected, anticoagulation therapy can be tried. 6, preventive measures: in the prevention of attacks, should be resolved in vivo infection foci, such as tonsillitis, dental caries, etc.; strictly prohibit smoking, prevent cold and humidity, abstain from sexual intercourse, enhance physical fitness, prevent trauma, oral anticoagulant drugs under the guidance of physicians when necessary.
