We treated 78 aneurysms in 77 patients.

- In case of compaction, patients had a lower rate of adequate (91% vs 52%, p= 0.005) and complete occlusion (36% vs 16% p= 0.05).

- The oversizing technique led to improved rates of no-compaction (36 vs 18%), complete occlusion (28 vs 13%) at last follow-up despite no statistical significance.

- For “>1 oversized WEB”, per-procedure complication rate was 3 times higher despite being non-statistically significant (p=0.07). At last follow-up, no-compaction risk was improved (48 vs 21%, p= 0.02) but complete and adequate final occlusion rates were not different.
