Spontaneous subarachnoid hemorrhage (SAH) is an extremely aggressive acute cerebrovascular disease, an intracranial disorder that can lead to immediate death in healthy individuals. It is a rupture of a blood vessel at the base of the brain or superficial parts of the brain, and blood enters directly into the subarachnoid space. The causes are intracranial aneurysms, arteriovenous malformations, hypertensive arteriosclerosis, smog and blood disorders as the most common. Benjamin Chiu is a subarachnoid hemorrhage caused by a ruptured aneurysm. The disease mostly occurs acutely in emotional agitation or under exertion, mainly manifested as severe headache and vomiting, and some patients may have coma and other symptoms. Studies have shown that the mortality rate of patients with subarachnoid hemorrhage, even when brought to the hospital in a timely manner, is more than 20%, and is primarily associated with rebleeding and delayed vasospasm, so early diagnosis and treatment are critical. In the past, subarachnoid hemorrhage relied mainly on cerebral angiography, and many patients were unable to undergo this test in time for medical reasons, thus missing the best time for diagnosis and treatment. With the development of imaging technology, non-invasive diagnosis has become possible, such as CTA and MRA. Timely elimination of aneurysm rupture and re-rupture is a fundamental measure to save such patients. Since the 1960s, craniotomy for clamping intracranial aneurysms has become the gold standard for the treatment of cerebral aneurysms. In the past 20 years, endovascular intervention has developed greatly. Prof. Hongyi Liu introduced that Zhao Benshan received interventional embolization treatment for aneurysm. The advantage of this method is that it requires less physical condition of the patient, creates conditions for subsequent treatment, and provides fast recovery after treatment. The advantages of craniotomy are the exact clamping and that it removes the subarachnoid blood accumulation and reduces cerebral vasospasm. Great progress has been made in the management of subarachnoid hemorrhage, but neurosurgeons and radiologists continue to face enormous challenges due to the complexity and aggressiveness of these disorders. There are still many unanswered questions about the diagnosis and treatment of subarachnoid hemorrhage, and we hope that in the near future these mysteries will be gradually unraveled, allowing more patients to receive standardized and rational treatment.
