For the indications of this operation, domestic and foreign guidelines for the treatment of acute ischemic cerebrovascular disease have clearly stipulated. In 2015, the American Heart Association and the Stroke Society officially updated the guidelines for early endovascular treatment of patients with acute ischemic stroke. The guideline has collected 8 international high-quality clinical studies since 2013, and made the highest level of recommendation for stent thrombectomy. The guidelines point out that for patients with internal carotid artery or proximal middle cerebral artery occlusion, stent removal should be performed as soon as possible within 6 hours of onset. Our country's guideline was released subsequently and made the same recommendation. Especially for patients with heart disease and atrial fibrillation, the thrombus directly comes from the heart, and the thrombus is large in size and often blocks the large intracranial blood vessels, causing severe symptoms in an instant. Stent removal can often play a miraculous effect.
In short, stent thrombectomy is the only existing technical means that can quickly remove thrombus from the body. If the patient has symptoms such as dizziness, vomiting, slurred speech, binocular staring, facial paralysis, coughing and swallowing difficulties, limb weakness, hemiplegia, hypoesthesia, unsteady gait, incontinence or even coma, especially if there is a history of atrial fibrillation Patients should be quickly transferred to a hospital with the technical conditions for stent and thrombectomy, so as not to delay the condition.
