Multidimensional Evaluation of Patients With Ruptured or Unruptured Cerebral Aneurysm Undergoing Endovascular or Surgical Treatment

Cerebral aneurysms are common changes in intracranial angioarchitecture. Unruptured aneurysms are increasingly identified thanks to the imaging techniques used in daily clinical practice. Since bleeding remains a highly dramatic event burdened by significant morbidity-mortality (about 50%), endovascular therapy, in combination with classic surgical therapy, is an essential element in contemporary medicine.Endovascular and surgical treatment represent the standard of care. The rationale of this study is to identify clinical and radiological characteristics, mainly neuro-radiological ones, not fully explored in previous studies, which can help predict the outcome of patients affected by cerebral aneurysm.The study will have the characteristics of a retrospective study on patients with cerebral aneurysm treated at our center from 1 January 2015 to 31 December 2023.Objective of the study is the multidimensional evaluation in patients with cerebral aneurysms, ruptured and unruptured, undergoing an endovascular embolization procedure or surgical treatment.

Inclusion Criteria:age > 18 yearsruptured or unruptured cerebral aneurysm with consistent neurologic and radiologic evidence.CT without contrast medium and CT angiography, demonstrating the SAH and the aneurysm.Execution of an endovascular embolization procedure (which is indicated by a neurosurgeon and interventional neuroradiologist) or surgical treatment.Exclusion Criteria:non-aneurysmal causes of SAH (example: AVMs, AVDs and trauma).
