Symptoms of carotid embolism?

summary

Carotid artery thrombosis is not uncommon in clinic, especially in the middle-aged and elderly people, mainly due to smoking and drinking, lack of exercise, excessive intake of high-fat and high sugar food. One of the major hazards of carotid artery thrombosis is that it is easy to lead to local blockage, resulting in organ ischemia, hypoxia and failure. So what are the symptoms of carotid embolism? Now let me say it for you.

Symptoms of carotid embolism?

1. Pain: pain is often the earliest symptom of patients with carotid artery thrombosis, and has the characteristics of radiation extending from the shoulder and neck to the distal end (limb end). Generally, it is a transient stabbing pain, which lasts for a short time, but the frequency will be faster and faster. But some patients with carotid artery thrombosis early pain symptoms are not obvious, about one fifth of patients with numbness.

2. Changes of skin color and skin temperature: microscopic examination of carotid artery thrombosis can find stenosis in the lumen of carotid artery, local blood circulation is not smooth, and clinically, local skin is pale, and there is color difference with surrounding skin. If there is still a small amount of blood in the blood vessels, the pale epidermis can also be seen scattered in the island like purple spots. If the ischemia is further aggravated, the neck muscles will be stiff and rotate unfavourably, the skin temperature of the affected part will drop, and the skin will show a variegated change, even purple and black.

3. Weakening or disappearance of arterial pulsation: the pulsation of cervical artery is obviously weakened, and the palpation is not strong. In general, the palpation of the artery starts from the dorsal pedis artery and the posterior tibial artery of the patient. If the pulse is not palpable, the popliteal artery is palpated and finally the femoral artery is palpated. This is due to the fact that the distal artery of the limb is far away from centrifugation. Once the carotid artery thrombosis worsens, the distal artery pulsation may even disappear.

matters needing attention

In clinical practice, carotid artery thrombosis occurs in high blood pressure, high blood lipid and high smoking addicts. At the same time, patients with coronary heart disease, atrial fibrillation, atherosclerosis and abdominal aortic aneurysm should be particularly vigilant in their daily life. Once the above symptoms appear, they need to see a doctor immediately. What should be reminded here is that although patients with carotid artery thrombosis need moderate exercise, morning exercise is easy to induce disease attack, so it should be avoided as far as possible.
