Cyanosis of the hands and feet
Introduction
Introduction to hand and foot cyanosis Acrocyanosis, also known as hand-foot purpura, hand-foot purple blue, is an unidentified peripheral vascular functional disease characterized by symmetry of the hands and feet and persistent skin blemishes. The age of onset is mostly around 20 years old, more common in young women, and rarely seen in men. Symptoms tend to ease after middle age, and there are persistent ones. The incidence rate is higher in patients with mental disorders. The patient is thinner, often said that the whole body is cold, the skin of both hands is twitching, the skin temperature is significantly reduced (the coldness of the touch), the hand is swollen, the disease is aggravated during the cold season and the limbs are drooping, during the warm season and when the hands are lifted Relieve, massage your hands and feet to reduce hair color or restore normal skin tone. basic knowledge The proportion of illness: 0.0025% Susceptible people: no special people Mode of infection: non-infectious Complications: swelling
Cause
Causes of hand and foot cyanosis
Cause (60%):
The etiology has not yet been clarified, and it is currently recognized to be related to endocrine disorders or dysfunction of vasomotor center. According to this disease, it is more common in adolescent women. Symptoms can be naturally relieved in the 25-year-old. The peripheral skin of the limbs is sensitive to cold, and the skin temperature is significantly reduced. The plexus is in a relaxed state, and emotional aggravation can aggravate the symptoms.
Pathogenesis (25%):
The disease may be caused by disorders of endocrine function and dysfunction of the vascular nerve center. The small arteries of the skin are in a paralyzed state, while the capillaries and venules are continuously dilated, the blood flow is slow and the blood oxygen concentration is lowered, so that the skin is present. Hair color, skin temperature decreased, nail fold microcirculation see capillary vasospasm expansion, distortion, slow blood flow, a state of congestion.
Prevention
Hand and foot cyanosis prevention
1. Should strengthen physical exercise, enhance physical fitness, quit smoking, avoid drinking tea and coffee.

Generally benign functional vascular disease, can be combined with finger swelling and stiffness.
Symptom
Symptoms of hand and foot cyanosis Common symptoms Hands and fingers are full of feelings, hands and feet, cold limbs, cyanosis, cold globulin, sinking...
The age of onset is mostly around 20 years old. It is more common in young women. It is rare in men. After middle age, the symptoms tend to be relieved, and there are persistent cases. The incidence rate is higher in patients with mental disorders.
The patient is thinner, often said that the whole body is cold, the skin of both hands is twitching, the skin temperature is significantly reduced (the coldness of the touch), the hand is swollen, the disease is aggravated during the cold season and the limbs are drooping, during the warm season and when the hands are lifted Relieve, massage the hands and feet can make the hair color reduce or restore normal skin tone, occasionally the skin feels mildly retarded. In severe cases, it is easy to get frostbite when the weather is cold, and the fingers are slightly swollen. For example, the frostbite of the hand is characterized by chronic frostbite. Such as agglomerate induration, hyperpigmentation, cold pain, itching when hot, ulcers and scars after healing.
Examine
Examination of hand and foot cyanosis
Skin color, skin elasticity check, blood routine, regular, electrocardiogram.
A microscopic examination of the nail fold showed that the capillary vasospasm was more dilated, and the blood flow in it was slow and stagnant, and the blood color was slightly red. There may be oozing around the tube, causing the tube to be unclear. Cold stimulation experiments are often positive.
Blood routine: Blood routine is the most common and basic blood test. Blood consists of two major parts, fluid and tangible cells, which are routinely tested for blood.
Diagnosis
Diagnosis and differentiation of hand and foot cyanosis
diagnosis
According to the symmetry of the skin of the hands and feet, the tinge is cold, the temperature is wet, the winter is aggravated, and more and more adolescent women, the normal pulse of the limbs, etc., can be diagnosed by excluding other diseases.
Differential diagnosis
1. Raynaud's disease and Renault sign: The patient has a typical regular change in the skin color of the extremities, that is, pale hair switch flushing normal, Renault sign is a complication of some diseases, so it is accompanied by the clinical manifestations of the primary disease.
2. Chronic frostbite syndrome: The clinical manifestations of chronic frostbite first, followed by diffuse skin color hairy.
