The relationship between the development of RICs and AVM obliteration after each GKRS
| Obliteration | Incomplete Obliteration | P Value | |
|---|---|---|---|
| Initial GKRS (No.) | 104 | 46 | |
| RICs (No.) (%) | 34 (32.7) | 16 (34.8) | .85 |
| Repeat GKRS (No.) | 16 | 9 | |
| Radiologic RICs after initial GKRS (No.) (%) | 9 (56.3) | 0 (0) | .007 |
| Radiologic RICs after repeat GKRS(No.) (%) | 3 (18.8) | 2 (22.2) | 1.0 |
