Minimally invasive for mild cerebral infarction is risky, including secondary cerebral embolism, brain cell injury, reperfusion injury and so on. 1. Secondary cerebral embolism: after the minimally invasive surgery, there is a possibility that the embolus may fall off, so the blood circulation will block the cerebral blood vessels and lead to cerebral embolism, which will lead to the damage of cranial nerve function, slurred speech, limb dysfunction and so on. 2. Brain cell damage: although it is minimally invasive surgery, there may be some damage to brain cells. 3. Reperfusion damage: if the blood vessel is reopened after minimally invasive surgery, the blood itself will cause reperfusion damage to brain cells. Although minimally invasive surgery for mild cerebral infarction is not complicated, there are still certain risks and complications during the surgery. If you feel unwell, you should go to the hospital in time and consult a specialist for guidance.
