About

This project proposes to establish a prospective cohort of MIA based on a preexisting multicenter MIA database and to combine multidimensional methods such as high-resolution magnetic resonance, hemodynamics, ambulatory blood pressure, and imaging histology to study aneurysm instability.

Enrollment: 1,000 estimated patients

Sex: All

Ages: 18 to 80 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Age 18-80 years old, male or infertile female;
• Diagnosed as IA (intracranial aneurysm) through CTA, MRA, or DSA; And it is suitable for endovascular intervention treatment
• The patient and/or their legal representative or guardian fully understand the research purpose, voluntarily participate and sign informed consent Books;
• Patients willing to cooperate with high-resolution magnetic resonance imaging.
• Patients willing to follow up and evaluate according to clinical research protocol requirements

Exclusion criteria

• AVM (arteriovenous malformation), Moyamoya disease, or DAVF (dural arteriovenous fistula) related aneurysms;
