Superficial phlebitis of the thoracoabdominal wall, also known as Mondor’s disease, is mainly found in the anterior chest wall, breast, rib cage and superficial epigastric veins. 1, etiology pathology: thrombotic superficial phlebitis of the thoracoabdominal wall occurs mostly in obese women, usually lack of labor exercise, the cause is not known, due to the sudden exertion of the upper limbs and strain, often constitute the triggering factors of the disease, probably in the anterior chest wall and upper abdominal wall under stress, the veins are also affected, or due to breast surgery strain. The thrombotic superficial phlebitis of the thoracoabdominal wall occurs in the following sites: ① Upper thoracoabdominal wall veins. As the nipple is directed downward, it passes through the breast crease and extends to the rib cage. ②Lateral thoracoabdominal veins: from the nipple outward and upward, stretching to the axilla from the nipple downward, and in the rectus abdominis muscle laterally straight to the lower abdomen. ③Superior abdominal wall vein. The superficial veins on the rectus abdominis are less common. When the intima of the above veins is damaged, there is thrombosis and causes an inflammatory reaction in the vessel wall and even invades the surrounding tissues of the involved veins, which may have exudates. The veins are swollen and white in appearance, with or without thrombus, which can grow, multiply and expand, and can involve branches, including small plexuses. When the pathological evolution stops, the inflammation subsides, the thrombus is mechanized and may recanalize and the vein is partially or completely occluded. Thrombotic superficial phlebitis of the thoracoabdominal wall, which belongs to the scope of “thoracic paralysis”, is caused by damp-heat accumulation, liver qi stagnation, trauma to liver ligaments, and stasis of blood in veins and ligaments. 2.Clinical manifestations: In general, there is no systemic reaction and only mild local symptoms. The typical history is that after the left hand or right hand is pulled by force, the pain is suddenly felt on one side of the chest wall with varying degrees, and the local pain will be felt when the upper arm is raised in motion, coughing, deep breathing, or the lesion is unintentionally pressed, and the pain will gradually ease after 2 weeks of the lesion and disappear after 4-8 weeks, and the local pain can be delayed for 1-2 years in individual patients. The superficial veins invaded by the lesion are slightly red and swollen, like cords, in the shape of silver fork or beads, with pressure pain, the cords are soft at the beginning and harden later, with a diameter of 3-5 mm. the affected veins are loosely adherent to the skin, but not to the deeper tissues and easily move. At both ends of the lesion, tensing the skin, the skin covering the superficial vein is depressed, shaped like a shallow groove or cords above the skin. After 2 weeks of lesion, the pain is reduced and the local skin is light brown. 3.Auxiliary examination: systemic reaction is light, white blood cell count is slightly increased, and local pathological examination can clarify the diagnosis. 4.Diagnosis and treatment: Stiff cords appeared under the skin on one side of the chest and abdominal wall of the patient, up to 15-40 cm long, with pinprick-like pain and a sense of urgency on the skin. The stiff cords are adherent to the skin. When the skin is stretched by pressing the two ends of the stiff cords, a sunken shallow furrow can appear on the skin. Because of the liver nature, the liver meridian is located in the two woes, the liver qi stagnation, liver loss of drainage, coupled with liver meridian damage, vein obstruction, stagnation of the meridian and become “chest paralysis”. The main treatment is to regulate qi and blood circulation, clear heat and detoxify the toxin, and take Chaihu Qinghe drink with reduction: Chaihu, angelica, red peony, jinyinhua, patchouli, yujin, zelan, heliotrope, heliotrope, Chenpi, etc. 5.Western medicine treatment: Because of the lightness and short duration of the disease, generally no special treatment is needed, and it can dissipate on its own. If the local symptoms are obvious, symptomatic treatment is available, such as sedation, analgesic treatment, commonly used enteric aspirin, ibuprofen, etc., the symptoms often quickly subside. 6, other therapies: acupuncture treatment is feasible, but not physical therapy, because the blood vessels are stimulated by dry heat, but produce spasm, making the symptoms worse.
