On May 29, our interventional vascular surgery department performed a right subclavian artery-right internal carotid artery bypass for an elderly male with severe deficiency of cerebral blood supply, which opened up the cerebral blood supply for this patient with severe deficiency of blood supply on the left side and no blood supply on the right side and relieved the life threatening condition. This patient is 78-year-old Master Zhang, who had severe dizziness for 4 months before the operation, which was not relieved after rest, and felt heavier dizziness for 1 month, and had difficulty seeing objects, hearing loss, and walking. After coming to the hospital for examination, the results surprised the doctor: cerebral angiography suggested occlusion of the right common carotid artery and near occlusion of the left side (stenosis >90%); cranial MRI suggested multiple The cranial MRI indicated multiple foci of cerebral infarction. Zhang’s condition is very dangerous, because the blood flow to the brain is supplied by both sides of the common carotid artery, Zhang’s right side of the common carotid artery is no longer able to supply blood, the left side of the blood vessel patency is less than 10%, in other words, Zhang’s brain is severely ischemic, which is the reason for his dizziness, vision and hearing loss, walking difficulties, and multiple brain infarcts! If the blood supply to the brain does not go up again, moncler outlet online there is a risk of another massive cerebral infarction at any time, which is life-threatening! In this case, only after vascular surgery to open up the blood supply to the brain could the life threatening situation be lifted. After admission, the doctors of interventional vascular surgery formulated a surgical plan for Master Zhang. After fully evaluating the characteristics of the carotid lesion and the systemic condition, Dr. Zhang Xiansheng and Dr. Guo Hongjie, deputy chief physician, decided to perform right subclavian artery-right internal carotid artery bypass surgery first. The three doctors, Zhang Xiansheng, Guo Hongjie and Chenggong, performed the surgery on Master Zhang on May 29. The most difficult part of the operation is two hurdles: one is in the right vascular bypass surgery, how to rely on the left side of the severely narrowed blood vessels to maintain the blood supply to the brain; the second is the surgery area involves a sensitive location, may be due to the vagus nerve reflexes and cause violent fluctuations in blood pressure, if you can not accurately control blood pressure, moncler outlet, Zhang’s life will also be in danger. Zhang Xiansheng, Guo Hongjie and Success operated carefully and finely anastomosed each blood vessel; Dr. Guan Tingting, deputy chief physician of the Department of Anesthesiology, closely observed the surgical process, and as the blood vessels were opened and blocked, drugs were precisely administered to maintain blood pressure, the surgery progressed very smoothly, and after anastomosing the blood vessels, the surgical experts felt the blood vessels pulsating! This means that the pathway to the blood supply to moncler outlet store Zhang’s brain is open! After the surgery, Zhang was sent to the intensive care unit for observation. To the doctors’ delight, Zhang spoke clearly and fluently after he regained consciousness, his hearing returned to normal, he could see clearly and his dizziness disappeared. The day after the operation, Zhang was sent back to the general ward and was able to move around normally. He was so happy that his life-threatening symptoms caused by insufficient blood supply to the brain had disappeared for some time. In recent years, the incidence of stroke in China has been increasing year by year, and its main danger is the extremely high rate of disability and mortality. The World Health Organization reports that stroke is the third leading cause of death worldwide and the leading factor in severe disability. Five million people die each year, and another five million are left with lifelong disabilities. China is a country with a high incidence of stroke, with about 2.5 million new cases of stroke each year and an average of one stroke every 12 seconds. Most are ischemic strokes, and 51% of ischemic strokes are caused by sclerotic stenosis and ulcerated plaque detachment at the carotid bifurcation. International research data, the North American Symptomatic Carotid Endarterectomy (NASCET) trial, confirmed that carotid endarterectomy reduces the risk of ischemic stroke in patients with symptomatic and asymptomatic severe carotid stenosis, and is currently one of the most effective treatments for carotid atherosclerotic stenosis. However, for patients like Zhang with complete occlusion of one carotid artery and severe stenosis of the other, the risk of the disease itself and the difficulty of treatment are enormous. Study data also show that patients with occlusion of one side of the carotid artery have a perioperative stroke and death rate of 14.3%, significantly higher than patients without carotid occlusion. The surgical treatment of severe bilateral carotid stenosis is still a difficult problem in the international vascular surgery community. The experience of interventional vascular surgery in treating Master Zhang marks the fact that our interventional vascular surgery has reached a leading level in China in the treatment of carotid artery sclerosis stenosis or occlusive disease.
