If postoperative precautions are strictly adhered to after internal carotid aneurysm intervention, the recurrence rate is not high, only about 2%. However, each patient’s physical condition and degree of illness is different, so the specific recurrence rate cannot be generalized. If the internal carotid aneurysm is completely removed during the operation, the blood pressure is well controlled after the operation to avoid secondary injury, and the patient goes to the hospital for regular checkups, usually the internal carotid aneurysm will seldom recur, and the chance of recurrence is only about 2%. If the blood pressure is not stabilized after the operation or if the neck is injured again by sharp or blunt force, the chance of recurrence of internal carotid aneurysm will increase. Therefore, it is recommended that patients undergo internal carotid aneurysm intervention and follow strict postoperative precautions. After the surgery, patients should maintain a light diet and balanced nutrition, keep the blood pressure stable, and go to the hospital for regular checkups to determine the recovery of their condition. If there are any abnormal symptoms such as wound swelling, bleeding or recurrence of the disease after the internal carotid aneurysm intervention surgery, patients should go to the hospital as soon as possible to consult the doctor and do not delay the disease.
