Question
Hello doctor, can you tell me how dangerous it is during stenting when the carotid artery is more than 90% narrow?

Answer
Carotid stenting is a minimally invasive method. This method is performed under anesthesia. To do this, the doctor will insert a long thin tube (catheter) through the skin, threaded into the femoral artery, gradually leading to the carotid artery. Because the carotid artery has the main task of bringing blood from the heart to the brain, during the stenting process, the carotid artery may encounter unexpected problems: hypotension, bradycardia, increased recurrence cerebral perfusion causing cerebral edema, cerebral hemorrhage or cerebral infarction due to plaque or blood clot
