Whether an aneurysm is serious or not needs to be analyzed according to the specific situation of the patient and cannot be generalized. It is recommended to seek medical examination in time to clarify the condition and take appropriate measures. Generally speaking, whether an aneurysm is serious or not is usually related to the size of the aneurysm, whether it is ruptured, and whether there is bleeding. If the aneurysm is small, such as less than 1mm in diameter, and is not accompanied by obvious discomfort, the condition is not serious, and some patients may not develop the disease for life, and regular review is usually sufficient without interventional surgery. However, aneurysm can affect the valve function and block the blood vessel, and the closer to the heart, the more serious the condition is. Patients are advised to go to a regular hospital for vascular surgery in a timely manner and undergo surgery and other related treatments under the guidance of a doctor to avoid delaying the condition. In addition, patients who undergo drug treatment need to take drugs strictly according to medical prescriptions, control blood pressure and heart rate, and have regular review. If the size of the tumor increases, surgery is required.
