Comparatively speaking, people are familiar with the complications of lower extremity artery of diabetes, but they know little about the arterial diseases of lower extremity caused by hypertension and hyperlipidemia. But it’s not that there are fewer patients, it’s ignored. These blood vessels in the legs are just as terrible as cardio cerebrovascular diseases.
If the “three highs” are not treated well for a long time, there will be complications of large blood vessels, mainly early or accelerated atherosclerosis. Atherosclerosis occurs not only in the coronary artery, but also in any artery. It is not uncommon for atherosclerosis to occur in the lower extremity artery. If the artery of the lower extremity is narrow or occluded, the leg will be cold, cold, numb, tired, unable to walk far or even painful, which will lead to foot ulcer or gangrene.
Generally, it takes more than 50% of lower extremity artery stenosis to have obvious symptoms, and it takes 10-20 years for patients from mild stenosis to 50% of blockage. During this period, patients have no symptoms or have mild symptoms, and they only feel that their legs are afraid of cold, fatigue and can’t walk far. Once there is obvious intermittent claudication, that is to say, leg ache occurs after walking for a short distance, and you need to sit down and rest for a while before you continue walking, it means that the leg is obviously under supplied with blood under the condition of activity.
If there is no diagnosis and treatment in this period, the disease develops further. When the patient is inactive, the leg also feels pain, and even the toe becomes black and necrotic, which indicates that the artery of the lower extremity has serious stenosis or occlusion, so some patients have to amputate.
Therefore, “three high” patients should not only pay attention to the occurrence of cardiovascular and cerebrovascular complications, but also pay attention to lower extremity vascular lesions. If you feel that your legs are afraid of cold, tired and can’t walk far, you should go to a hospital with a peripheral vascular department or vascular surgery in time to have a check on the color Doppler ultrasound of the lower extremity artery, segmental pressure measurement of the lower extremity artery, etc., to find early diagnosis and take timely treatment measures to avoid more serious lower extremity vascular disease.
