What this trial studies

This observational study collects clinical, laboratory, and imaging data from patients with intracranial aneurysms who have undergone Pipeline implantation. The aim is to evaluate the safety and efficacy of the Pipeline embolization device, focusing on aneurysmal occlusion status, incidence of in-stent stenosis, and functional prognosis. Additionally, the study assesses hemodynamic changes before and after the stent implantation. The data gathered will help in understanding the outcomes associated with this treatment approach.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 22 to 75 with diagnosed unruptured intracranial aneurysms suitable for Pipeline embolization.

Not a fit: Patients with contraindications to flow-diversion treatment, other significant vascular lesions, or those who are pregnant or lactating may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve treatment strategies for patients with intracranial aneurysms, potentially leading to better outcomes and reduced complications.

How similar studies have performed: Other studies using flow-diverter devices for treating intracranial aneurysms have shown promising results, indicating that this approach is supported by prior evidence.
