Abstract

A 44-year-old female experienced a recurrence and enlargement of a basilar top aneurysm 2 years after initial treatment with a Woven En-doBridge (WEB) device. Retreatment using a new WEB device combined with a flow diverter (FD) via a semi-jail technique successfully oblit-erated the aneurysm without complications. Follow-up imaging at 4 months showed complete occlusion and favorable outcomes. This case suggests that combining WEB and FD may offer effective retreatment for complex, recurrent aneurysms, enhancing coverage and durability. Despite its technical challenges, this approach shows promise, though further long-term studies are needed to confirm its safety and wider applicability.
