Patient's question:
What are the causes of subarachnoid hemorrhage in newborns? The baby's face is purple, the whole body is flushed, and there is crying after stimulation at birthDoctor's answer:
The causes of intracerebral hemorrhage can also lead to diseases, but it is the most common cause of intracranial aneurysms, arteriovenous malformations, hypertensive arteriosclerosis, vascular network abnormalities (Moyamoya disease), and blood disorders. Under conditions of emotional excitement or excessive fatigue. Aneurysms occur in the branches of the cerebral arteries of the aorta, and are more common in the anterior part of the circle. Arteriovenous malformations are mainly located in the middle cerebral artery distribution area of the cerebral hemispheres. After the blood vessel ruptures and enters the subarachnoid space of the brain, the contents of the cranial cavity increase, pressure increases, and secondary vasoconstriction occurs. The latter is caused by the traction of clots and fibrous cords around the blood vessel wall (mechanical factors), and smooth muscle walls of the blood vessel wall. The neuromuscular junction formed between cells causes extensive ischemic injury and edema.
