Psychiatric Outcomes of Unruptured Intracranial Aneurysms (POUIA)

Microsurgical clipping of intracranial aneurysms involves craniotomy to access the brain, locating the aneurysm, and placing a small metal clip across its neck, thereby isolating it from normal blood circulation to prevent rupture.

Any endovascular embolization of intracranial aneurysms that involves navigating microcatheters through the vascular system to the site of the aneurysm and deploying materials like coils, flow-diverting stents, or endosaccular flow disruptors to occlude the aneurysm and reduce the risk of rupture.

Surveillance imaging for brain aneurysms is a diagnostic approach that uses imaging techniques such as MRI, MRA, CTA, or DSA to regularly monitor the status of detected brain aneurysms. The goal is to track changes in the aneurysm's size, shape, or structure over time, which may indicate an increased risk of rupture. This ongoing assessment helps healthcare providers decide whether to continue monitoring or to consider treatment options, such as surgical clipping or endovascular coiling, based on the aneurysm's characteristics and the patient's risk factors.
