Limb pain should not be taken lightly There are many causes of limb pain, such as neurological diseases, skin and muscle lesions, peripheral vascular lesions, bone and joint lesions, etc. The limb pain that occurs in the elderly should be taken seriously. Dr. Meng Qingyi, chief physician of the Department of Vascular Surgery of Jinan Central Hospital, said that the onset of limb pain in the elderly is initially characterized by slightly cold extremities, mild numbness and easy fatigue after activities. After gradual development, muscle pain, spasm and weakness appear after activity, which must be stopped and relieved after rest. With further development of the disease, pain, numbness, abnormal sensation, coldness of the extremities and weakened or absent arterial pulsation may occur even at rest, which may eventually lead to severe ischemic necrosis of the affected limbs. In addition, elderly people with this disease also have hypertension, diabetes, high cholesterol and other diseases. He also pointed out that the diagnosis of this disease can be made by non-invasive tests, such as Doppler ultrasound, in addition to clinical manifestations. If necessary, angiography can be performed to clarify the location, extent and degree of the lesion and to guide the development of a treatment plan. Once the disease is diagnosed, conservative treatment can be used first to correct the risk factors that lead to the progression of atherosclerosis and to prevent its complications. For the treatment of vascular surgery disease, Dr. Qing-Yi Meng, chief physician, explains: The ideal treatment for large artery stenosis or occlusive lesions, regardless of the stage, is angioplasty or bypass graft surgery. If the patient is not suitable for these two treatments, medication should be considered to relieve pain, heal the ulcer and avoid amputation. There are two major types of specific surgical treatments: 1. Endoluminal vascular surgery treatment, i.e., the use of catheters for transvascular endoluminal treatment, including balloon dilation, metal stent placement, sclerotic plaque spinotomy, laser angioplasty, etc., to open the lesion and restore the blood supply to the distal limb. This method is less traumatic, less painful, faster recovery and shorter hospitalization time, which is the more ideal method today. 2, surgical treatment, that is, according to the condition of the lesion, the use of arterial endothelial stripping plus angioplasty or artificial vascular bypass surgery, etc.. He went on to talk about the treatment of acute arterial embolism. Acute arterial embolism is one of the common emergencies in vascular surgery. The emboli originate from rheumatic heart disease, mitral stenosis, atrial fibrillation, and coronary artery disease. When the embolus is dislodged and pushed distally by blood, blocking the arterial blood flow can lead to necrosis of the limb or internal organs. Because of the rapid onset of these diseases and acute ischemia of the limbs, untimely diagnosis and treatment can result in limb necrosis and even life-threatening. Therefore, early diagnosis and early treatment are especially important. When a patient with heart disease suddenly develops pain in one limb, coldness in the distal limb and white skin color, it may be this disease and should be treated by a specialist in time. If the condition allows, it can be treated by surgery. The surgery is small, simple, short, and has immediate results.
