In the western countries, By Pass – vascular bypass surgery is a household name just like our appendectomy, because the incidence of lower extremity vascular obstruction is very high due to ethnicity and dietary reasons. In our country, this year, due to the increase of life pressure and bad dietary habits, the incidence of atherosclerosis has increased significantly, the lower extremity vascular obstruction patients also increased significantly, and the academic community on the treatment of arterial obstruction of the lower extremities from a single bypass grafting, and gradually shifted to a more minimally invasive and physiological interventional procedures – balloon dilatation, stenting, however, the majority of cases of arterial obstruction is a very long section of the arteries, and some of the arteries are completely occluded. However, most cases of arterial blockage section is very long, some of the arteries are completely occluded, the guide wire catheter for interventional surgery can not be inserted into the past, simple interventional surgery can not completely solve the problem, the vascular surgery department of the hospital, the successful simultaneous use of interventional, vascular bypass bridge technology to do hybrid surgery, to solve a number of complex, difficult lower extremity vascular obstruction cases, which is greatly ahead of the hospitals in Guangzhou City. Zheng Bo, a morning walker, was hospitalized because of “intermittent claudication”. We did an angiogram and found that his left iliac artery was completely blocked, and the right iliac artery was also 75% blocked. In this case, because the left artery was completely occluded, it was not possible to directly insert the catheter guide wire with an interventional procedure. In this case, because the left artery was completely occluded, it was not possible to insert the catheter guidewire directly into the left artery, and it was not feasible to do so. The traditional surgery, which involves opening up the abdomen and bridging the abdominal aorta and the iliac arteries with artificial blood vessels, would be very traumatizing and risky. For this reason, we designed a new surgical plan: balloon dilatation of the right iliac artery, implantation of a stent to avoid the high risk, traumatic open heart surgery, and then we only need to make two small incisions in the root of the thighs on both sides of the two sides of the femoral artery bypass grafting can be done with very little trauma, the blood from the right side of the left side to solve the problem of the ischemia of the left lower limb, Zheng Bo’s recovery was very fast, and he could go down to the ground in 48 hours. He was discharged from the hospital a week later. Two years later, I still often see Uncle Zheng wandering around Liwan Lake. There are two types of chronic arterial obstructive diseases: one is atherosclerotic occlusive disease, which usually occurs in older people over the age of 50. It is mainly atherosclerosis that leads to changes in blood vessel walls and complicates thrombosis, and is associated with hyperlipidemia and heavy smoking. The other is thromboembolic vasculitis, which usually occurs in younger patients, has an undetermined etiology, and is clearly related to smoking. The lesions begin with paroxysmal arterial spasms that flare up when walking. This results in “intermittent claudication”, and as the arterial blockage worsens, the blood supply to the lower extremities becomes significantly insufficient, resulting in persistent pain and hard-to-heal ulcers on the lower extremities. Now there are vascular bypass and minimally invasive interventional surgery, as long as early to the vascular surgery, the patient can often relieve the pain, the ulcer healing, to avoid the pain of amputation. The first step in preventing this type of disease is to quit smoking and eat a healthy diet to avoid hyperlipidemia. Appropriate use of lipid-lowering drugs for patients with hyperlipidemia has a preventive effect.
