Stents can be placed in 84-year-olds with cerebral infarction who meet the indications for stenting. There is no age limit for stenting. If an 84-year-old man with cerebral infarction has severe stenosis of large blood vessels and meets the indications for stenting without contraindications, he can be treated with stent implantation surgery. Prior to the surgery, it is necessary to judge the elderly’s cardiopulmonary function, liver and kidney function, and whether they are tolerant to the surgery. If they meet the requirements of the surgery, the elderly can undergo stenting, which can improve the stenosis of the cerebral blood vessels, restore the cerebral blood flow, promote the recovery of cerebral function, and prevent the recurrence of the cerebral infarction. Cerebrovascular stenting is a minimally invasive surgery, which is less traumatic to the body, can be performed under local anesthesia, and has a small risk of adverse outcomes, but there are risks associated with surgery such as cerebral hemorrhage, cerebral vasospasm, and contrast nephropathy. Patients are advised to consult their primary care physician to determine whether to undergo stenting based on their specific condition.
