简介:
脑动脉粥样硬化狭窄
Cerebral atherosclerosis is a chronic disease involving the cerebral blood supply arterial system, characterized by progressive lipid deposition, fibrous tissue proliferation and inflammatory cell infiltration.
Atherosclerotic stenosis is a major cause of ischemic stroke. The annual incidence of stroke in China is 116 to 219 per 100,000 persons, and the ischemic stroke accounts for 70%.

  • 症状

    Cerebral atherosclerosis develops slowly and insidiously, and patients usually have no specific symptoms in the early stage. But with cerebrovascular stenosis progresses and affects cerebral blood flow, patients may show ischemia-related symptoms, such as insomnia, irritability, and neurasthenia-like symptoms; in addition, they may also develop headache, dizziness, dizziness or other symptoms. With the progression of the disease, long-term cerebral ischemia and hypoxia may cause degenerative changes in patients’ nerve cells and lead to cerebral atrophy. Patients may develop atherosclerotic dementia, and even mental symptoms such as irritability, depression, illusion or delusion. If the lesion involves the cerebral stem bundles on both sides of the cortex, the patient may also experience choking on water, dysphagia, hoarseness of voice, and clumsy movement of the limbs.
  • 风险

    Patients with cerebral atherosclerosis are prone to ischemic stroke due to varying degrees of stenosis or occlusion of the cerebral arteries, and are therefore at risk of disability or death.
  • 诊断

    Blood routine and biochemical examinations can be adopted to determine whether patients have high-risk factors for atherosclerotic stenosis, such as hyperlipidemia; head CT scan and head MRI (magnetic resonance imaging) can also be used to assess brain tissues for any changes due to ischemia; in addition, digital subtraction angiography (DSA) and computed tomography angiography (CTA) can be used to assess blood vessels and blood flow and to find out whether there is vascular stenosis.
解决方案
01

Balloon angioplasty

Balloon angioplasty involves the delivery of a guidewire into the vessel with the support of angiography, and the delivery of a therapeutic balloon dilation catheter along the guidewire to the lesion, followed by balloon dilation to improve the stenosis to unblock the blood vessel and restore blood flow.

02

Stent implantation

Stent implantation involves the delivery of a therapeutic stent system along the guidewire or catheter to the lesion with the support of angiography, followed by release of the stent to improve and maintain the vessel diameter through the radial support of the stent, to unblock the blood vessel and restore blood supply.
