FIGURE 1.
Time and cause of reinterventions after multilayer flow modulator (MFM) implantation
| Patient number | Time after MFM implantation (months) | Cause of reintervention; reintervention undertaken |
|---|---|---|
| 1. | 25 | Endoleak type I and enlargement of the aneurysm; implantation of another MFM |
| 2. | 3 | Insufficient proximal seal and collateral flow, resulting in enlargement of the aneurysm; implantation of another MFM |
| 3. | 1 | Insufficient proximal seal; implantation of another MFM |
| 4. | 8 | Enlargement of aneurysm and partial stenosis of subclavian artery; implantation of another MFM into previous MFM |
| 6. | 13 | Stenosis of brachiocephalic truncus; implantation of a stent, which resulted in a stroke |
| 9. | 9 | Migration of the MFM; implantation of another MFM |
| 10. | 74 | Displacement of MFM and stent graft; implantation of another stent graft |
