The treatment procedures

A comparison of microsurgical clipping, coiling, stent-supported procedures, flow diverters, and bypass procedures—each with its principles, advantages, disadvantages, and occlusion, recurrence, and complication rates.

Implement this information on the website as a collapsible table, not as continuous text: Patients can refer to it specifically after a particular procedure has been suggested to them. The "Disadvantages" column is crucial—it's the reason this table is even on a hospital website.

• Who decides: Every case is discussed in our interdisciplinary neurovascular conference, comprised of neurosurgery, neuroradiology, and neurology. You will receive a joint recommendation – not a single opinion.

Interactive element (Level 2, from WP2/GUIDE-IA): a "decision aid" that compares the magnitude of one's own 5-year rupture risk with the treatment risk. Important: No risk calculator with individualized numerical output without medical supervision (liability and MDR issues). Recommendation: illustrative case examples ("Two people, two 4-mm aneurysms, two different recommendations") instead of a calculator – the two case vignettes from the center presentation remain suitable.
