The incidence of peripheral vascular disease is increasing year by year, but the public’s understanding of these diseases is inconsistent, and even some non-specialists may misdiagnose and miss diagnosis, such as treating typical intermittent claudication as lumbar disc herniation or mistaking lower limb deep vein thrombosis for dysentery. Peripheral vascular diseases, clinically, are a collective term for vascular diseases other than cardiovascular diseases, including diseases of the arterial, venous and lymphatic systems. Arterial diseases commonly include: arterial stenosis and occlusive diseases, such as atherosclerotic occlusive disease and arterial embolism, which are common in the elderly; arterial dilatation lesions, such as aneurysms; arterial inflammation, such as multiple aortitis, thrombo-occlusive vasculitis and nodular arteritis; external pressure lesions, such as thoracic outlet syndrome and arterial extrusion syndrome; peripheral arterial dysfunction, such as Raynaud’s disease (phenomenon); and others include arteriovenous fistulas, peripheral vascular lesions of diabetes mellitus, etc. Venous diseases include: varicose veins and thrombotic superficial phlebitis of superficial veins; deep venous system includes: deep vein thrombosis, post-deep vein thrombosis syndrome, primary deep vein valve insufficiency, pulmonary embolism complicated by deep vein thrombosis; also includes Buga’s syndrome, K-T syndrome, etc. Diseases of the lymphatic system are dominated by inflammation and obstructed reflux, such as lymphangitis, dermatitis, and lymphedema. As the incidence increases, the dangers of peripheral vascular disease are becoming more important. For example, aneurysm in various parts of the body is like a “time bomb” hidden in the body, once ruptured, it is very difficult to deal with; atherosclerosis occlusive disease, arterial embolism, diabetic gangrene, etc. can lead to limb ischemia, which not only causes unbearable limb pain, but also requires amputation in serious cases; and carotid artery sclerosis stenosis can lead to stroke, paralysis, etc.; some veins and lymphatic vessels can be damaged. Some venous and lymphatic system reflux diseases, such as deep venous valve insufficiency and lymphedema, can lead to perennial lower limb swelling and even ulcer formation, forming what is commonly known as “old rotten feet”, which seriously affects the patient’s daily life. The symptoms of peripheral vascular disease vary depending on the nature of the disease. Common lower extremity arterial stenosis and occlusive diseases, such as atherosclerotic occlusive disease, due to insufficient blood supply to the distal extremities, manifest as intermittent claudication at the beginning, i.e., soreness, weakness or pain in the lower extremities after walking a certain distance, which can be relieved after rest, and the symptoms worsen at a later stage, with resting pain and gangrene of the extremities; while the lower extremity arterial embolism caused by atrial embolus dislodgement, the condition changes much more rapidly, as the affected extremity Acute ischemia causes coldness, numbness, and pain in the lower extremities, and once irreversible ischemia occurs, it can easily lead to widespread gangrene of the limbs, and many patients have to have their limbs amputated to save their lives. Aneurysms are usually asymptomatic, except for superficial ones that may be occasionally felt by the patient, and deep ones such as subclavian, iliac, and visceral aneurysms are often not easily detected, but they are often fatal – untreated aneurysms can grow to a certain point and rupture. Most people are familiar with the symptoms of saphenous varicose veins, namely “bruising” of the lower extremities, swelling and soreness, hyperpigmentation, and itching, but these chronic symptoms are not always taken seriously and are often not seen until thrombophlebitis or ulcers form. We suggest that, on the one hand, we should properly enhance our awareness of self-care, and those who are in a position to do so should have regular medical checkups; on the other hand, when peripheral vascular disease is suspected, we should go to a vascular surgery specialist as much as possible to avoid delaying treatment.
