Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Improvement in shunt volume flow within 24 hours after angioplasty as measured by the difference in shunt volume flow post-intervention minus pre-intervention Main target: - Difference of shunt volume flow from post-intervention to pre-intervention | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary outcome variables: - Difference in shunt volume flow after 1 and 3 months compared to baseline (pre-intervention) - frequency of complications (bleeding, occlusion, change of procedure), - duration of the intervention, - Reintervention rate within 3 months | — |
