Introduction Basilar tip aneurysmscan bechallenging to treatgiven their location andoftencomplex geometryand size.Endovascular coilinghas historically been the standardoftreatmentfor less complex aneurysms, proving to bebothsuccessfulandsafe.However, recanalization ratesfor large and giant aneurysmshave beenunacceptably high.More recently, devicessuch asthe Woven EndoBridge (WEB) have been developed toreduce the rate of recanalization.Here we describea uniquecase of alarge basilar tip aneurysm that was treated withcombination oftheWEBdeviceandcoilembolizationsimultaneously. Methods Case report. Results A woman in her fifties presented with several days of headache, nausea and vomiting, vision changes, and unsteady gait. MRA of the brain visualized a large unruptured basilar tip saccular aneurysm which was confirmed via a diagnostic cerebral angiogram (size: 12.9×11.2×14.0 mm, neck: 4.5 mm) [Figure 2A]. Given the sizeand locationof the aneurysm,we attempted embolization with the largest available WEBSLdevice. This device was undersized for the aneurysm.We therefore utilized a novel combinationcoiling,to partially fill the dome and posterior aneurysm sac,and the largest WEB SL available (11×9 mm). Using a radial system, the WEB device was partly unsheathed at the base of the aneurysm. Then, using a femoral system three coils (18 Hydroframe 28cm 7mm, 18 Hydroframe 15cm 7mm 10, 10 Hydroframe 23cm 7mm) were introduced into the remaining space of the aneurysm, filling the void between the aneurysm dome and the partly deployed WEB SL device. Once all coils were appropriately placed and stable, the WEB device was fully deployed, which lead to successful embolization and occlusion of the aneurysm [Figure 2B]. Conclusions The challenge of treatinglargebasilar tip aneurysmshasencouragedthedevelopment of innovative devices and novel interventional techniques.Here we demonstratethepossibility ofcombiningaWEBdevicewith standard coilingto treatlarge, wide‐necked basilar tip saccularaneurysms that are not ideal candidates for standard therapy.
