Every tissue and organ in the human body must have good blood circulation to maintain normal function, if the vascular disease of the organ is inevitably caused by the abnormal function of the organ, so that vascular disease involves the whole body, from head to foot everywhere. Moreover, if vascular diseases are not diagnosed and treated correctly in time, the consequences can be very serious, leading to disability in mild cases and death in severe cases. The common symptoms of vascular disease are: 1. Pain: Pain in any part of the body can be vascular disease. Cerebrovascular disease, aortitis and carotid arteriosclerosis are mainly manifested by headache and dizziness, while coronary heart disease, thoracic aortic aneurysm and pulmonary embolism are mainly manifested by chest pain, and vascular lesions in the abdomen (such as abdominal aortic aneurysm, aortitis and mesenteric vascular lesions) are mainly manifested by abdominal pain. Vascular diseases of the extremities are mainly pain in the extremities and hands and feet, such as vasculitis, venous thrombosis, etc. 2, swelling: swelling confined to a certain part, mainly poor venous reflux, deep vein thrombosis is the most common, thrombus dislodgement can lead to pulmonary artery embolism and sudden death. 3, varicose veins: varicose veins are not simple, risking surgery to cause trouble. 4, chronic ulcers: sores do not close for a long time, vascular disease nutrition is not enough. 5, cold hands and feet: cold hands and feet, poor blood supply. Vasculitis, arteriosclerosis occlusive disease and other arterial obstructive disease of the extremities in the early stage are manifested as cold hands and feet, so cold hands and feet can not be careless, if accompanied by pain, it is basically certain that there is a vascular problem, must be promptly to the specialist hospital, at this time, if you can get a clear diagnosis and treatment more than no serious consequences, miss this time may suffer a long time of pain. 6, dizziness: dizziness is mostly cerebral ischemia. Vascular lesions in the brain, atherosclerosis of the neck, aortitis are the main symptoms of dizziness, and dizziness can also occur with poor heart function. 7, skin color change: skin color change, more vascular lesions. The color of the skin is closely related to blood circulation. Pale skin color is insufficient blood supply, mostly seen in vasculitis, arterial embolism, etc.; purple skin color is stasis, mostly seen in poor venous return; red skin color is vascular expansion, mostly seen in hemangioma, erythema limb pain, etc. If the skin appears intermittent pale → purple → red changes, called Raynaud’s syndrome, mostly seen in scleroderma, lupus erythematosus and other vasculitis caused by. 8, numbness: numbness is mostly due to insufficient blood supply to the nerves. Especially diabetic patients, prone to peripheral neuritis and numbness in the hands and feet, the foot is more common, and even the formation of painless feet and loss of pain sensation, resulting in suffering trauma and can not feel, prone to the formation of diabetic gangrene. Other such as arterial embolism, thrombo-occlusive vasculitis, arteriosclerosis occlusive disease, etc. can also appear numbness of the hands and feet. 9, blood pressure is not normal: asymmetric blood pressure in the extremities, there must be a vascular problem. More often seen in aortitis, can appear in the upper extremity blood pressure disappears, the pulse disappears. Upper extremity atherosclerosis occlusive disease can appear the blood pressure of both upper extremities inconsistent, a difference of 20mmHg that there is definitely a vascular problem. There is also thoracic outlet syndrome. Some patients present with hypertension in the upper body and hypotension in the lower body or vice versa. As long as the blood pressure in the extremities is not symmetrical, there is definitely a vascular problem. Therefore, it is important to measure the blood pressure of the extremities in patients with hypertension or hypotension.
