If the onset of cerebral infarction is within 6 hours, emergency interventional therapy can be performed, i.e. cerebral artery thrombus mechanical thrombectomy, the surgery takes the right femoral artery puncture placement, and then through the femoral artery sheath will be sent to the miniature stent to cause cerebral infarction in the intracranial vascular thrombus, and then open the stent back to pull the stent, which will enable the artery thrombus to be taken out, out, the surgery is relatively simple, and the operation time is relatively short, in about 1 hour can be completed. This procedure is relatively simple and takes a relatively short time to perform, and can be completed in about one hour. If the scope of cerebral infarction is very large, complicated by serious cerebral edema, the patient has dilated pupils, the formation of cerebral hernia, then it is necessary to perform craniotomy and debridement decompression surgery, which requires craniotomy and debridement, and the operation time is relatively long, usually about 3 hours.
