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.

Introduction Stroke is a leading cause of morbidity and mortality, and many factors predict a poor outcome, including age, NIH Stroke Scale (NIHSS), ambulatory status, and ability to swallow1. Mood disorders have previously been associated with an increased risk of cardiovascular disease2. The association between pre‐existing mood disorders and stroke outcome, however, has not been well studied. The objective of the current study was to explore the impact of pre‐existing depression on functional outcomes post‐endovascular treatment. Methods We reviewed the records of 178 patients who received mechanical thrombectomy (MT) at our institution[BH1][BM2] from 2019–2022. We collected data on baseline characteristics and demographics, including functional outcome at 90 days as measured by modified Rankin Scale (mRS), which was categorized as favorable (mRS 0–2) or unfavorable (mRS 3–6). Results Of patients who received MT, 54 (30.3%) had a prior medical history of depression. On univariate analysis, patients with a history of depression had 2.5 times higher odds of an mRS score of 3–6 (cOR = 2.47, 95% CI = 1.11‐5.48). Multivariate analysis included history of smoking, hypertension, obesity, Alberta Stroke Program Early CT Score (ASPECTS)[YC1][KC2], time to recanalization, and discharge NIHSS score, along with history of depression. We found that the odds of having an unfavorable mRS were 5 times higher in those with a history of depression than those with no history (aOR = 5.15, 95% CI = 1.09‐23.31). Additionally, discharge NIHSS was associated with 1.5 times higher odds of unfavorable mRS for each point increase in NIHSS score (aOR = 1.47, 95%CI = 1.25‐1.74). While pre‐existing depression was associated with poorer functional outcomes, it was not associated with mortality, cOR = 1.12, 95%CI = 0.55‐2.27. Conclusions In this study, we found that a prior medical history of depression is associated with unfavorable functional outcomes at 90 days in patients who received MT. Future studies should investigate the association between the severity of depression and stroke outcomes and explore methods to mitigate the impact of depression on stroke outcomes.
