RESUMO
The endovascular clip system device, eCLIPs (eVasc, Vancouver, British Columbia, Canada), was introduced almost a decade ago for the treatment of wide-neck bifurcation aneurysms,1-3 which represent a challenge for both endovascular and surgical approaches. Several techniques and devices (intrasaccular or intra-arterial) have been introduced and are currently available in order to improve the technical and clinical outcomes of aneurysm embolization. Flow diversion and flow disruption have shown controversial results in this subtype of aneurysm. In this video we present the use of the eCLIPs device to treat a ruptured, wide-neck aneurysm of the top of the basilar artery. The decisional approach, technical details, and the different steps of the endovascular treatment are described. The final part of the video is dedicated to the characteristics of the device for re-endothelialization4 and flow diversion (video 1).5 neurintsurg;16/3/229/V1F1V1Video 1 .

The Woven EndoBridge (WEB) is an intra-aneurysmal flow disruptor designed for the treatment of broad-based arterial aneurysms with a high safety and effectiveness profile.1, 2 It does not require concomitant antiplatelet therapy compared to other devices such as flow diverters or intracranial stents. Innominate artery pseudoaneurysms are a rare consequence of blunt traumatic injury, infection, or atherosclerotic disease.3, 4 We describe the case of an innominate artery pseudoaneurysm successfully treated with a WEB SL device instead of stenting, therefore alleviating the need for dual antiplatelet therapy. The treatment was successful and uneventful and postprocedural computed tomography angiography confirmed the complete occlusion of the pseudoaneurysm.
RESUMO
PURPOSE: Pulsatile tinnitus can be caused by a high-riding jugular bulb (HRJB), characterized by the superior position of the jugular bulb in the petrous temporal bone. The anatomical position and morphology of this entity make it challenging for endovascular treatment. We report our experience with two patients successfully treated with a stent-assisted Woven EndoBridge (WEB; Microvention, Tustin, CA, USA) device. MATERIALS AND METHODS: We describe two cases of HRJB in patients presenting with disabling pulsatile tinnitus. Temporary balloon occlusion of the jugular bulb prior to the intervention reduced tinnitus intensity. Both patients were subsequently treated under general anesthesia with the WEB device deployed in the HRJB which was held by a stent deployed in the sigmoid sinus. RESULTS: Both procedures were successful with good positioning of the WEB device and no procedural complications. Both patients had complete resolution of pulsatile tinnitus immediately after the procedure. Follow-up imaging showed successful occlusion of the venous cavity with a widely patent stent. CONCLUSION: Among patients with pulsatile tinnitus caused by an ipsilateral HRJB, a stent-assisted WEB device seems to be a viable endovascular option with angiographic and clinical success.
RESUMO
BACKGROUND: Guidelines recommend the treatment of emergent large vessel ischemic stroke (ELVIS) patients presenting beyond 6 hours of last known well time with endovascular thrombectomy (EVT) based on perfusion computed tomography (CT) neuroimaging. We compared the outcomes (long-term good clinical outcomes, symptomatic intracranial hemorrhage (sICH), and mortality) of ELVIS patients according to the type of CT neuroimaging they underwent. METHODS: We searched the following databases: Medline, Embase, CENTRAL, and Scopus from January 1, 2015, to June 14, 2023. We included studies of late-presenting ELVIS patients undergoing EVT that had with data for non-perfusion and perfusion CT neuroimaging. We followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Data were pooled using a random effects model. RESULTS: We found 7 observational cohorts. Non-perfusion versus perfusion CT was not statistically significantly different for both long-term clinical (n = 3,224; RR: 0.96; 95% CI 0.86 to 1.06; I2 = 18%) and sICH (n = 3,724; RR: 1.08 95% CI 0.60 to 1.94; I2 = 76%). Perfusion CT had less mortality (n = 3874; RR: 1.22; 95% CI 1.07 to 1.40; I2 = 0%). The certainty of these findings is very low because of limitations in the risk of bias, indirectness, and imprecision domains of the Grading of Recommendations, Assessment, Development and Evaluations. CONCLUSION: The use of either non-perfusion or perfusion CT neuroimaging may have little to no effect on long-term clinical outcomes and sICH for late-presenting EVT patients. Perfusion CT neuroimaging may be associated with a reduced the risk of mortality. Evidence uncertainty warrants randomized trial data.
