Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Aneurysm progression at t=18 months | — |
Secondary
| Measure | Time frame |
|---|---|
| Seconday outcome measures are growth at 6 and 12 months, need for elective aneurysm repair, rupture, death, and an inventory of possible side-effects (questionnaire).
