The most frequent strategy was coiling (21\/36, 58%), followed by SAC (7\/36, 19%), WEB embolization (6\/36, 17%) and flow diversion (2\/36, 6%). A successful aneurysm occlusion (defined as RROC 1 and 2) on the final angiogram was achieved in 30\/36 (83%) aneurysms including all patients presenting with baseline subarachnoid haemorrhage and 25\/36 (69%) were occluded completely. Complete occlusion (RROC 1) was more frequently achieved in ruptured BAFAs (15\/25, 60% v. 2\/11, 18%; p\u2009=\u20090.031). Procedure-related complications occurred in 3\/36 (8%) aneurysms. Re-treatment was executed in 12\/36 (33%) aneurysms. After a median angiography FU of 38 months, 30\/31 (97%) BAFAs were occluded successfully and 25\/31 (81%) showed complete occlusion.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Reconstructive endovascular treatment of BAFAs is technically feasible with a good safety profile.
