There is definitely a risk of stenting in patients with cerebral infarction, as there is a risk in any surgical operation. If a patient with cerebral infarction is put under stent, it means that the patient’s atherosclerosis is relatively heavy, and the general stenosis rate is more than 75%. If stenting is not performed, the patient may experience recurrence of cerebral infarction and serious blockage of the aorta at any time, and may even be left with sequelae such as hemiplegia, aphasia, etc., and the more serious ones may be life-threatening. Stenting is a very effective treatment for cerebral infarction, but in the process of stenting, because it is a surgical operation, the guide wire needs to travel from the femoral artery to the internal carotid artery and middle cerebral artery inside the skull, which has a relatively long travel, and there may be a small plaque dislodged in the process of the surgical operation, which may lead to the reoccurrence of cerebral infarction. If the vascular anatomy of the brain is thin, it may be combined with cerebral hemorrhage during stenting, and this risk exists in all cases.
