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.

Such as agglomerate induration, hyperpigmentation, cold pain, itching when hot, ulcers and scars after healing.

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 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.
