Rupture of intracranial aneurysms can lead to extensive subarachnoid hemorrhage (SAH), a potentially fatal neurological emergency with mortality rates ranging from 8 to 67%. At present, surgical clipping (SC) and endovascular coiling (EC) are two main treatments for aneurysmal subarachnoid hemorrhage (aSAH), in recent years, the improvements in surgical equipment and techniques have already greatly improved the postoperative safety of patients. However, considering individual differences between patients, some still at risk due to possible complications during hospitalization or after discharge from the hospital, it will no doubt generate a large healthcare burden. This prospective, observational clinical trial (LongTEAM) is to improve the diagnosis and treatment effect and efficiency in this field, reducing mortality, medical costs, and medical burden, while opening up new avenues for interdisciplinary clinical practice and scientific research exploration.
