Old Li is an old smoker, every day to smoke a pack of red double happiness cigarettes, however, from September last year, he found his two calves from time to time the phenomenon of cramps, walking a little farther leg pain, the left side than the right side of the serious, so he began to make up for their own calcium, and often go out to the sunshine, but the symptoms are still there. Recently strolling in the Expo Park, not yet walked to 500 meters, leg pain is obvious, must rest for a while to walk again, and can only limp walking. At first he thought he walked walked more, leg and foot pain only, and later found that not walking when both legs have pain, and calves and feet cold, but also some numbness. So, Lao Li went to the hospital to see a doctor, at first he could not figure out which section he should see, first went to the orthopedic department to see, check the bones, muscles have no problem; to the neurological examination, the nerves did not find a problem, and finally some people suggested to the vascular specialist, only to find out that the original is their own arteries in the lower limbs out of the problem, the doctor’s diagnosis is “lower limb atherosclerosis occlusive disease The doctor’s diagnosis was “arteriosclerosis of the lower limbs”. What are the main clinical symptoms of lower limb atherosclerotic occlusive disease? Lower limb arteriosclerosis occlusive disease is a manifestation of systemic arteriosclerosis, is a common vascular disease in middle-aged and old people, mainly abdominal aorta, iliac artery, femoral artery and other large and medium arterial intima-media thickening and hardening, the formation of atherosclerotic plaques and calcification, the blood vessels gradually become narrower, and even secondary to thrombosis, resulting in arterial occlusion, manifested as lower limb ischemia symptom, in accordance with the change of the condition has the following clinical staging: 1, minor complaints Period: patients only feel the affected limb skin temperature decrease, fear of cold, or mild numbness, easy to fatigue after activity, limb tinea pedis is easy to infection and not easy to control. 2, intermittent claudication period: when the patient is walking, due to the lack of oxygen and ischemia, the more common part is the muscle of the calf produces spasm, pain and fatigue and weakness, must stop walking, after resting for a few moments the symptom is relieved, can continue the activity. Symptoms recur if the patient walks for a longer distance. Intermittent claudication of the calf is the most common symptom of lower limb ischemic lesions. 3, resting pain period: when the lesion is further developed, and the establishment of collateral circulation is seriously insufficient, so that the affected limb is in a rather serious ischemic state, even at rest, feel pain, numbness and abnormal sensation. The pain is generally dominated by the end of the limb. 4.Tissue necrosis stage: it mainly refers to the lesion continues to develop to the occlusion stage, the collateral circulation is very limited, and the symptoms of nutritional disorder appear. Before the occurrence of ulcers or gangrene, the skin temperature decreases and the color is dark purple. Early gangrene and ulcers tend to occur in the toes, and with the progress of the lesion, the infection and gangrene can gradually develop upward to the foot, ankle or even calf, and in severe cases, systemic poisoning symptoms can appear. In ancient times, the motherland medicine for this disease has long been recorded, “Medical Zong Jinjian”, “Surgery Zhengzong” have detailed records: Yin cold in the veins and collaterals, cold condensation blood stasis, blood stasis, blood stasis, stasis for a long time to become hot, heat and toxicity congestion, blood corruption and decay. The etiology of the disease is phlegm, blood stasis, phlegm and blood stasis, blocking the veins. Chinese medicine belongs to the category of “pulse paralysis”. So how did Lao Li get arteriosclerosis of the lower limbs? The causes of lower limb atherosclerosis occlusive disease are complex, of which the two most important and dangerous causative factors are smoking and diabetes mellitus. In addition, high blood pressure and high blood lipids will also accelerate atherosclerosis of blood vessels throughout the body. In fact, the incidence of lower extremity atherosclerotic occlusive disease is very high, people over 65 years old, both men and women, the incidence rate may be more than 10%, which is equivalent to the age of the population in this age group may be 1 in 10 people with the disease. The disease is most common in people aged 50-70, and there is a tendency for the onset of the disease to occur earlier. Observe our relatives and friends around us, if you can not walk 500 meters at a time, walking with a limp, always have to walk and rest, calves and feet cold, but also some numbness, it should be vigilant, it is likely to be caused by arterial ischemia of the lower limbs, if not to attract enough attention, let it continue to develop, and finally there may be lower limb necrosis, ulceration. Our country because of this situation amputation every year about hundreds of thousands of people. At present, the treatment of lower extremity atherosclerotic occlusive disease has conservative treatment, surgical treatment and endovascular interventional therapy three methods. 1.Conservative treatment: It is suitable for patients with relatively mild condition, taking treatment such as lowering blood pressure, lowering lipids, anti-platelet aggregation, controlling blood sugar, and taking Chinese medicine orally. This method can delay the progression of lower extremity atherosclerotic occlusive disease, but can not fundamentally eliminate the lower extremity atherosclerotic occlusive disease of vascular stenosis, occlusion; 2, surgical treatment: mainly for severe segmental lower extremity arterial stenosis, occlusion, the use of surgical procedures, removal of vascular luminal plaques, vascular bypass reconstruction, artificial vascular replacement and other operations, re-open the lower extremity arteries. However, this kind of surgery is traumatic and risky, especially not suitable for patients with lower limb atherosclerosis occlusion combined with serious cardiovascular and cerebrovascular diseases and diabetes; the requirements for surgical anesthesia are also higher. 3, vascular endoluminal intervention: for serious lower limb arterial stenosis, occlusion, take modern vascular minimally invasive intervention technology, not traditional surgery to implement the treatment. This method has the advantages of small trauma, simple operation, precise efficacy, repeatable operation, low requirement of anesthesia and analgesia, etc. It is especially suitable for the elderly and weak, combined with cardiovascular and cerebrovascular diseases; it is the direction of development of vascular surgery for the treatment of vascular diseases, and it is very suitable for patients who can not be treated with open surgery and ineffective conservative treatment. In recent decades, with the continuous development of medical technology, endovascular intervention or endovascular intervention combined with surgery has gradually replaced the traditional single vascular surgery method, and become the first choice for the treatment of this disease, which not only has the advantages of less trauma, less pain, and faster recovery, but also can significantly reduce the pain of amputation of the patient. Vascular endoluminal intervention combined with traditional Chinese medicine is a promising comprehensive treatment method. Vascular endoluminal intervention better solves patients’ arterial segmental stenosis and occlusion in lower limbs, traditional Chinese medicine prevents and reduces re-stenosis and re-occlusion after vascular intervention treatment, and at the same time, for the lower limbs with blood supply obstacles, ulcers, and gangrene limbs, it is dialectically typed and staged; it activates blood circulation and removes blood stasis, clears heat and removes toxins, and benefits the vital energy to replenish the kidneys. Internal and external treatment with traditional Chinese medicine can greatly improve the blood circulation of limbs, relieve symptoms, promote wound healing, reduce recurrence of disease and lower the rate of limb amputation. Lower limb atherosclerosis occlusive disease should be early detection and early treatment. Patients can first observe on their own whether there is claudication when walking? There is also a simple self-check method: touch the calf, the dorsum of the foot, feel whether the temperature of the calf and foot is reduced or cold? Are the arterial pulsations on the dorsum of the foot weakened or hard to feel? If the dorsum of the foot is cold and the arterial pulsations on the dorsum of the foot are weakened or difficult to feel, it is likely that the blood vessels of the lower limbs are narrowed or occluded. Timely go to the hospital for a lower limb artery ultrasound or CT examination, can be clearly diagnosed. If early detection and early treatment, patients may be saved from the pain of surgery. Patients should exercise properly in daily life, live a regular life, keep the affected limbs warm, avoid high-fat, multi-salt, over-sweet food, and do not smoke: patients with high blood pressure or diabetes should control their blood pressure and blood sugar, and actively treat the primary disease. Appropriate Chinese medicine conditioning is beneficial to health.
