What are the symptoms of arterial embolism pain?

The pain caused by arterial thrombosis is a common symptom. In addition to the pain, there are also symptoms and hazards such as pale complexion, numbness of the legs and feet, movement disorders, and weakened arterial pulsation.

1. Patients with acute arterial embolism without collateral circulation compensation have a rapid progression of the disease. Typical symptoms of acute arterial embolism include pain, pallor, coldness, numbness, movement disorders, and weakened or absent arterial pulsation. The severity of symptoms depends on the location and extent of the embolism, the amount of secondary thrombosis, whether there was previous arteriosclerotic disease causing arterial stenosis, and the status of collateral circulation. Pain. Pain is often the first symptom to appear, gradually extending to distant areas. For about 20% of patients, numbness is the first symptom, but the pain is not obvious.

2. Changes in skin color and temperature, blood circulation in the limbs is impaired, the blood in the subpapillary venous plexus of the cortex is emptied first, and the skin becomes waxy and pale. If a small amount of blood still accumulates in the blood vessels, scattered small island-like purple spots may appear among the pale skin. The superficial veins are collapsed, the capillaries fill slowly, and the gastrocnemius muscles are doughy. As ischemia progresses, the muscles may become stiff and the skin temperature of the affected limb decreases, which is most obvious in the distal part of the limb. The skin temperature change is actually one joint lower than the true embolism plane. In patients with embolism at the end of the abdominal aorta, skin temperature changes occur approximately in the bilateral thighs and buttocks, in the common iliac artery approximately in the lower thigh, in the common femoral artery approximately in the middle thigh, and in the popliteal artery approximately in the lower leg.

3. The arterial pulsation weakens or disappears, and the proximal arterial pulsation may increase. However, it is important to identify the arteries distal to the embolism because the impulse of the blood is transmitted to the distal arteries, where conductive pulsations may be palpable.

4. Numbness and movement disorders: The distal end of the affected limb shows a stocking-shaped infection loss area, which is due to functional disorders caused by peripheral nerve ischemia. There is an area of ​​decreased sensation proximally, and an area of ​​hyperesthesia further proximally. The affected limb may also have a tingling sensation, weakened muscle strength, and even paralysis.
