An overview of device and microcatheter distribution with respect to target vessel and aneurysm location in our cohort
| Device location | No of treated aneurysms | No of 2.25 mm diameter FDS implanted | No of 2.75 mm diameter FDS implanted | No. of 3.25 mm diameter FDS implanted | Microcatheter: Excelsior SL10 | Micro- catheter: Headway 17 |
| Anterior communicating artery complex* | 12 | 14 | 1 | 0 | 11 | 1 |
| Pericallosal artery | 2 | 2 | 0 | 0 | 2 | 0 |
| Middle cerebral artery† | 5 | 2 | 1 | 1 | 0 | 3§ |
| Vertebral artery | 3 | 1 | 1 | 1 | 1 | 2 |
| Internal carotid –posterior communicating artery‡ | 5 | 0 | 0 | 6 | 0 | 5 |
* Due to distal shortening in three cases, 15 flow diverting stents (FDS) were implanted.
† One patient had two neighboring middle cerebral artery (MCA) aneurysms which were treated with one FDS (patient no 2).
‡ One case of proximal shortening occurred which demanded implantation of an additional FDS to sufficiently cover the aneurysm.
§One MCA was treated using the same Headway 17 as employed for the treatment of a posterior communicating artery in the last row (patient no 17).
