Background and Purpose-Stent-assisted coiling has expanded the treatment of intracranial aneurysms, but the rates of procedure-related neurological complications and the incidence of angiographic aneurysm recurrence of this novel treatment are not yet well known. We present our experience with stent-assisted coiling with special emphasis on procedure-related neurological complications and incidence of angiographic recurrence. Methods-Clinical and angiographic outcomes of 1137 consecutive patients (1325 aneurysms
More angiographic recurrences are detected over time. Complex coils do not augment aneurysm packing. Packing is not related to protection against recurrence.
Background and Purpose:
The efficiency of prehospital care chain response and the adequacy of hospital resources are challenged amid the coronavirus disease 2019 (COVID-19) outbreak, with suspected consequences for patients with ischemic stroke eligible for mechanical thrombectomy (MT).
Methods:
We conducted a prospective national-level data collection of patients treated with MT, ranging 45 days across epidemic containment measures instatement, and of patients treated during the same calendar period in 2019. The primary end point was the variation of patients receiving MT during the epidemic period. Secondary end points included care delays between onset, imaging, and groin puncture. To analyze the primary end point, we used a Poisson regression model. We then analyzed the correlation between the number of MTs and the number of COVID-19 cases hospitalizations, using the Pearson correlation coefficient (compared with the null value).
Results:
A total of 1513 patients were included at 32 centers, in all French administrative regions. There was a 21% significant decrease (0.79; [95%CI, 0.76–0.82];

<0.001 in 2019) and in transferred patients (mean 182.6±SD 82.0 minutes versus 153.25±67;
P
<0.001). After the instatement of strict epidemic mitigation measures, there was a significant negative correlation between the number of hospitalizations for COVID and the number of MT cases (

Conclusions:
Our study showed a significant decrease in patients treated with MTs during the first stages of the COVID epidemic in France and alarming indicators of lengthened care delays. These findings prompt immediate consideration of local and regional stroke networks preparedness in the varying contexts of COVID-19 pandemic evolution.
Direct cervical arterial approaches to accessing the intracranial circulation is effective in patients in whom the femoral route does not allow the navigation and stabilization of guiding catheters.
BACKGROUND AND PURPOSE:Five commercial devices are available for mechanical thrombectomy in acute ischemic stroke. This study evaluated and compared the resultant arterial damage from these devices.
Background and purposeFlow diversion is an innovative and increasingly used endovascular treatment for intracranial aneurysms. Its initial evaluation with the first devices available showed good efficacy of this treatment with variable safety results. The Flow Direction Endoluminal Device (FRED) has a specific design and was evaluated in a single-arm, multicenter, prospective, Good Clinical Practice study: SAFE (Safety and efficacy Analysis of FRED Embolic device in aneurysm treatment). This analysis reports clinical results at 1 year and anatomical results at 6 months and 1 year.MethodsPatients with unruptured and recanalized aneurysms located in the anterior circulation treated with FRED and FRED Jr were prospectively included. A Clinical Event Committee and a Core Laboratory independently evaluated clinical outcome and anatomical results.ResultsThirteen interventional neuroradiology centers included 103 patients/aneurysms. Aneurysm locations were supraclinoid internal carotid artery (ICA) in 71 (68.9%), cavernous ICA in 15 (14.6%), anterior cerebral or anterior communicating artery in 9 (8.7%), and middle cerebral artery in 8 (7.8%). Most aneurysms were small (<10 mm) in 71 patients (68.9%). Cumulative 1-year mortality and morbidity rates were 2/103 (1.9%) and 3/103 (2.9%), respectively, one death being related to cancer. At 1 year, anatomical results were: complete occlusion in 66/90 patients (73.3%), neck remnant in 7/90 patients (7.8%), and aneurysm remnant in 17/90 patients (18.9%).ConclusionsSAFE study analysis at 1 year confirms the excellent safety profile of the FRED device for aneurysm treatment, with low morbidity and mortality rates (2.9% and 1.9%, respectively) and demonstrates its efficacy (adequate occlusion in 73/90 (81.1%)).Clinical trial registrationUnique identifier: NCT02921698; Results.
