What to check for vasculitis

Vasculitis should be examined in time. It is a vascular occlusive disease. The earlier the treatment, the better the effect will be, and the patient will recover best. It is more important in the process from diagnosis to treatment. The examination method is more important. If you have vasculitis, you can get some examination results through physical examination. In addition, you can check through arterial color ultrasound and arteriography. Once the diagnosis is confirmed, you must actively carry out good treatment.

What to check for vasculitis

1. It can be clarified through physical examination.

It is possible to check whether the patient's arterial pulsation is weakened or absent. The patient lies flat on his back and raises his lower limbs to 45°. After three minutes, observe whether the skin color of the patient's feet changes. Generally speaking, the skin on the feet of patients with vasculitis appears pale or waxy yellow. The ischemia is more obvious when pressing with the fingers, and the patient feels pain and numbness. Ask the patient to sit up, and then let the lower limbs hang naturally. The patient's skin color will recover slowly or appear bluish purple.

2. Use arterial color Doppler ultrasound to check for vasculitis.

This method can detect the direction of blood flow and determine the degree of lumen stenosis. This method is helpful in detecting the location of thrombus, the severity of plaque, and the degree of blood vessel blockage. Arterial color ultrasound is a routine examination method for occlusive arteriosclerosis.

3. The third method is arterial angiography

This method is the clearest way to examine vasculitis. Arteriography can clearly identify the location, range, nature and degree of vascular occlusion. It is also possible to understand the establishment of lateral circulation in the patient's limbs. However, we need to remind everyone that this method is invasive and may cause arterial spasm and endothelial damage, aggravating limb ischemia. Therefore, arteriography is generally not used as a routine examination method for vasculitis.

Susceptible groups: High-risk groups for vasculitis are smokers (especially young and middle-aged men), people with mental stress, people with unbalanced nutrition, residents of cold and humid areas, and those with family genetic factors. Most cases occur in men aged 20-40 and are rare in women.
