A persistent intracranial murmur, a continuous murmur like the roar of a machine, aggravated by heart contraction, often interfering with sleep, can be heard in the frontal area with a stethoscope, and the murmur diminishes or disappears when the affected common carotid artery is compressed with a finger. Fractures at the base of the skull can cause injury to the cavernous sinus segment of the internal carotid artery or its branches, or direct injury to the artery from firearm injury or sharp injury, or rupture of the wall of the internal carotid artery in the sinus segment from the violent turbulent blood flow during trauma. These factors can also cause punctate hemorrhage or limited injury to the arterial wall, and later rupture of the cavernous sinus segment due to violent fluctuations in blood pressure. So, how should patients with persistent intracranial murmur prevent the deterioration of their condition? The following is a brief introduction: 1, should try to avoid cold stimulation, and avoid living in an overly humid environment. 2, smokers, should strictly quit smoking. 3, should pay attention to the rational structure of the diet, and to develop good eating habits. 4, to maintain a good mental and emotional, and strive to “treat people with generosity, optimism,”.
