In the past three to four years, he has always felt coldness in his left leg, and after walking for a while, he feels that his left leg is not as strong as his right leg, and he has leg weakness. Every time the leg weakness occurs when walking, you want to smoke a cigarette to pressure, and then every time you stand for a few minutes, after smoking this cigarette, you feel better, and then do not care about this problem. What is the reason for such a symptom? Because the patient did not care, has not been going to the hospital, but walking after the emergence of leg weakness of the distance is getting shorter and shorter, each time to relieve the need to smoke, but also more and more, the last six months even 100 meters can not walk, and not only leg weakness, but also the symptoms of pain in the calf stomach, a hospital examination, a vascular ultrasound found that the original thigh segment of the femoral artery blocked. What is the disease of thigh artery blockage? It turns out that the muscles of our body need oxygen, and the artery on the thigh is the pipeline that carries oxygen to the lower extremities, if the pipeline is blocked, less oxygen will be delivered to the lower extremities, then our lower extremities will be “hypoxic”. Symptoms include the following: 1, the affected limbs are cold, cold; 2, after the activity of the leg or hip muscles easily fatigue, muscle pain, can be relieved after rest, this is the most common, also known as “leg weakness”; 3, foot, calf and even thigh cramps; 4, leg sensory abnormalities, there can be numbness, burning sensation; 5, When resting legs may have numbness; 6, legs feel cold; 7, pale or purple skin; 8, impotence; 9, foot wound healing difficulties; 10, muscle atrophy; 11, foot or toe necrosis; 12, toenail deformation thickening; 13, lower limb pain; 14, calf hair thinning. Now the patient understands that the oxygen transport pipeline of his legs is blocked, the legs, lack of oxygen, which is the case of “leg weakness”, and every time a cigarette pressure, in fact, is to stand and rest for a while, to relieve, but smoking will aggravate the blockage of the arteries, so his symptoms are getting worse. What should be the treatment? At present, there are three main treatment methods for lower limb artery stenosis and occlusion diseases: 1, drug treatment: drugs are the most basic treatment method, for the stenosis and occlusion caused by atherosclerosis, related drug treatment should be carried out, such as controlling blood sugar, blood lipids, secondary prevention, to prevent cardiovascular and cerebrovascular events. 2.Surgical arterial reconstruction surgery: including various bypass surgeries (femoral artery-femoral artery, femoral artery-popliteal artery, etc.), but because of the great damage and lack of repeatability, it is no longer the first choice of treatment in most cases. 3. Minimally invasive treatment of lower extremity arteries: including balloon dilation, stent implantation and other minimally invasive procedures. Because of the advantages of small trauma and reproducible operation, it has been used as the preferred treatment method. Nowadays, many patients choose to undergo minimally invasive surgical treatment. Let’s take a look at the situation of minimally invasive surgery. First of all, before the surgery, a CTA of the arteries of the lower extremities will show that there was actually a very thick artery that was dedicated to supplying blood to the lower legs and feet. After the surgical implantation of the arterial stent, the blood flow was so good that the patient could feel his feet warming up right on the operating table. With our latest endovascular suturing technology, there is no need to apply pressure for 24 hours as before, and the wound stops bleeding at the end of the surgery. Our vascular surgeons suggest that when you experience cold legs, weakness or even pain in the legs after walking activities, you should be further examined to avoid serious consequences, especially for the following groups of people. 1, long-term smoking; 2, hypertension; 3, diabetes; 4, hyperlipidemia.
