“…Increasing the number of devices and the procedural time have been related to intra/periprocedural complications. 11 12 Although low profile stents and low-profile FDs have shown great benefits for the treatment of aneurysms located distal to the circle of Willis, [12][13][14] the use of a lower profile FD for aneurysms arising more proximally has not been assessed.…”

BackgroundThe aim of this study was to assess the technical success and procedural safety of the new Silk Vista device (SV) by evaluating the intraprocedural and periprocedural complication rate after its use in several institutions worldwide.MethodsThe study involved a retrospective review of multicenter data regarding a consecutive series of patients with intracranial aneurysms, treated with the SV between September 2020 and January 2021. Clinical, intra/periprocedural and angiographic data, including approach, materials used, aneurysm size and location, device/s, technical details and initial angiographic aneurysm occlusion, were analyzed.Results60 aneurysms were treated with SV in 57 procedures. 66 devices were used, 3 removed and 63 implanted. The devices opened instantaneously in 60 out of 66 (91%) cases and complete wall apposition was achieved in 58 out of 63 (92%) devices implanted. In 4 out of 66 (6%) devices a partial opening of the distal end occurred, and in 5 (8%) devices incomplete apposition was reported. There were 3 (5%) intraprocedural thromboembolic events managed successfully with no permanent neurological morbidity, and 4 (7%) postprocedural events. There was no mortality in this study. The initial occlusion rates in the 60 aneurysms were as follows: O’Kelly–Marotta (OKM) A in 34 (57%) cases, OKM B in 15 (25%) cases, OKM C in 6 (10%) cases, and OKM D in 5 (8%) cases.ConclusionsOur study demonstrated that the use of the new flow diverter Silk Vista for the treatment of intracranial aneurysms is feasible and technically safe.

Background Eclipse 2L is a new double lumen balloon microcatheter for neurovascular use, with several design features that separate it from previous generation devices. We aimed to report our initial experience of balloon-assisted coiling of intracranial aneurysms using the Eclipse 2L balloon. Materials and methods Retrospective single-center review of patients who underwent balloon-assisted coiling with the Eclipse 2L balloon, for ruptured or unruptured intracranial aneurysms between 1 June 2016 and 31 December 2018. Cases with adjunctive use of stents and recurrences of previously embolized aneurysms were excluded. Patient files were used to extract aneurysm characteristics, complications, immediate and long-term results. Results We identified 120 patients with 126 aneurysms, of which 83 (65.8%) unruptured. Average aneurysm size was 5.9 mm (standard deviation 3.2 mm), with a dome-to neck-ratio of 1.7 (SD 0.6). Most aneurysms (79.3%) were wide necked. Immediate angiographic exclusion (Raymond-Roy grade I–II) was obtained in 95.1% of cases (81.7% grade I and 13.4% grade II). Procedural morbidity was 3.2% with no procedural mortality. Follow-up imaging was available for 115 aneurysms (91.2%). After an average follow-up period of 8.9 months (SD 7.3 months), 96.5% of aneurysms presented class I–II occlusion. Two aneurysms (1.7%) were retreated during follow-up. Conclusion Balloon-assisted coiling using the Eclipse 2L double lumen balloon is feasible for aneurysms in a wide range of locations in the anterior and posterior circulation. The angiographic results and complication rates compare favorably with previously published studies.

“…The low-profile visualized intraluminal support (LVIS; MicroVention, Aliso Vajo, USA) device is a braided and self-expanding device, which has been used to treat broad-neck, complex cerebral aneurysms [1][2][3][4][5][6][7][8][9][10][11][12][13]. In a systematic review of the use of braided stents in early studies (2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016)(2017) involving 35 studies comprising 1426 patients [14], the overall successful stent delivery and complete aneurysm occlusion rates were 97% and 88.3%, respectively.…”

Objectives:Even though low-profile visualized intraluminal support (LVIS) device is used extensively currently and provide intraluminal support in complex cerebral aneurysm embolization, only few studies have reported its clinical results. This study presents the results of patients treated with LVIS.Patients and methods:Cerebral aneurysms with an undefined neck, fusiform shape, and blood blister-like aneurysms that were treated with LVIS between May 2017 and May 2019 were reviewed retrospectively.Results:Overall, 112 aneurysms in 104 patients were treated using LVIS, and 105 LVISs were placed. Of these, 101 aneurysms (90%) were small (< 10 mm) in size, 17 were fusiform aneurysms, and 3 were blood blister-like aneurysms. Overall, 39 patients suffered a subarachnoid hemorrhage and 65 had no bleeding history. 2 patients died of internal carotid artery (ICA) thrombosis, resulting in 1.9% mortality rate. Follow-up angiography was obtained in 68 patients (65%), and the complete obliteration rate was 98.5% in 6–12 months.Conclusion:The LVIS is a safe and effective treatment for small ruptured or unruptured complex intracranial aneurysms.
