Eligibility
Inclusion criteria
Inclusion criteria: 1.Retrospective Study 1: No age restriction, no gender restriction. 2.Retrospective Study 2: The patient was treated with commercially available MicroVention WEB devices for intracranial aneurysms. 3.Retrospective Study 3: The patient has undergone at least one postoperative imaging re-examination. 4.Prospectiveness 1: No age or gender restrictions. 5.Prospectiveness 2: Patients are treated for intracranial aneurysms using the commercially available MicroVention WEB device. 6.Prospectiveness 3: The subjects (or their legal representatives, if applicable) shall fully understand the research requirements and procedures, and provide written informed consent prior to any research procedures being performed.
Exclusion criteria
Exclusion criteria: 1.Retrospective Study 1: Patients are treated with WEB devices, yet they cannot obtain imaging data from intraoperative or postoperative re-examinations. 2.Retrospective Study 2: Patients deemed ineligible by researchers to participate in this study. 3.Prospectiveness 1: The subject is participating in or plans to participate in another clinical study that may affect the results of this study during the follow-up period of this study. 4.Prospectiveness 2: The patient is currently or expected to be unavailable for follow-up. 5.Prospectiveness 3: The patient has a life expectancy of less than one year due to other diseases or conditions. 6.Prospectiveness 4: Researchers believe that these patients are not eligible to participate in this study.

Secondary
| Measure | Time frame |
|---|---|
