Red streaks, swimming superficial veins
Introduction
Introduction Migratory thrombophlebitis: The superficial vein of the affected limb has a red cord and can resolve after a few weeks. After a period of time, it can appear in different or the same part, accompanied by pain and tenderness. It is one of the clinical manifestations of thrombotic vasculitis. The disease mainly manifests as limb ischemia, migratory phlebitis due to ischemia, ischemic neuropathy and secondary infection. The course of disease progression can be divided into three phases. Ischemic phase, dystrophic phase and tissue necrosis. Improvement of eating habits and proper exercise and foot care are important to prevent the disease.
Cause
Cause
Mainly due to the lack of vitality of the patient, the blood can not reach the end of the blood vessel, and the finger or toe can not be nutritious and gradually necrotic.

an examination
The disease mainly manifests as limb ischemia, migratory phlebitis due to ischemia, ischemic neuropathy and secondary infection. The course of disease progression can be divided into three phases.
Phase I: ischemic period
(1) Intermittent claudication: The affected limb is cold, numb or firmness. When walking a certain distance, there is pain or pain in the calf or sole, and rest can be relieved. As the disease progresses, intermittent claudication symptoms worsen.
(2) Migratory thrombophlebitis: The superficial vein of the affected limb has a red cord and can resolve after a few weeks. After a period of time, it can appear in different or the same part, accompanied by pain and tenderness.
(3) The pulsation of the dorsal artery or posterior tibial artery is weakened or disappeared.
Phase II: Nutritional Disorders
(1) Resting pain: The rest of the affected limb is still painful and unbearable, especially at night, the pain is not enough, and it does not sleep all night.
(2) Limb dystrophy: dry and thin skin, hair loss, calf muscle atrophy, skin chills, pale or flushing, arterial pulsation disappears.
Phase III: tissue necrosis
(1) Have work, stage II symptoms.
(2) ulcers or gangrene at the extremities: the initial stage is dry gangrene, often appearing dry or black at one or two toes or toenails, gradually involving the entire toe, often forming a difficult ulcer after detachment. Such as secondary infection, dry gangrene can be converted to wet gangrene.
Diagnosis
Differential diagnosis
There is a red and low-heat cord in the superficial vein: the main feature of superficial venous thrombosis is pain in the thrombotic site. There is a red, low-heat cord in the superficial vein, tenderness, and redness around. The disease is divided into two types: infectious and non-infective. Infectious people are more common in acute infection, childbirth, pelvic or abdominal surgery, non-infectious people are caused by blood stasis, and more common in the posterior vein of the calf.
Shallow varicose veins of the lower extremities: the vast majority of large saphenous varices (a small number of small saphenous varicose veins or varicose veins) are clinically very common, with approximately 25% of women and 15% of men worldwide having such Diseases and onsets are often associated with genetic factors, and long-term standing and heavy physical work can be a cause.
Local venous chord-like: a strip or induration 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 thrombosis. Superficial phlebitis.
