“…The patients were admitted to the hospital for DSA examination at 3, 6, 12, and 24 months postoperatively; the mean angiographic follow-up was (8.25 ± 1.68) months (range, 6-24 months). The immediate postoperative angiogram and follow-up images were evaluated according to the Raymond-Roy Occlusion Classification: [12][13][14] Complete occlusion was considered Raymond grade I, residual neck was considered Raymond grade II, and dome filling was defined as Raymond grade III. The follow-up outcome was assessed using the mRS score, the 0-3 score was regarded as a good outcome, and the 4-5 score was regarded as poor outcome.…”

Objective Enterprise stent has been widely used for assisted embolization in wide-necked aneurysms while delayed ischemia or thromboembolic complications for its incomplete stent apposition. The purpose of this study was to summarize and analyze the clinical experience of using Enterprise 2 (EP2) stent-assisted embolization in the treatment of paraclinoid aneurysms. Methods From January 2019 to December 2020, the clinical and imaging data of 98 patients with paraclinoid aneurysms treated with EP2 stent-assisted embolization were enrolled retrospectively. Preliminary experience and follow-up outcomes of EP2 stent-assisted embolization of paraclinoid aneurysms were assessed by using the Raymond grade and modified Rankin Scale. Results Of the 98 aneurysms, all stents were released satisfactorily. The immediate postprocedural angiography revealed a complete occlusion of the aneurysms with 77.55% of the (76/98) patients, and the last follow-up angiograms showed complete occlusion with 83.67% of the (82/98) patients. The average aneurysm size was (4.11 ± 1.25) mm, the aneurysm diameter was (4.41 ± 1.37) mm, the vessel radius was (3.87 ± 0.32) mm, the diameter at the distal of stent was (3.23 ± 0.21) mm, and the proximal was (4.18 ± 0.23) mm. Among the 98 aneurysms, 13 cases had incomplete stent apposition, 3 cases had intraoperative knotting, and the stents were improved post adjusted; 2 cases had vasospasm and 1 case had stenosis during operation, the symptoms were improved after symptomatic treatment. The result demonstrated that stent length and inner bending radius of parent artery were the pivotal factors affecting incomplete stent apposition (P < 0.01). Conclusion The EP2 stent for the treatment of paraclinoid aneurysms is safe and effective, however, the length of the stent and the inner bending radius of parent artery are important factors affecting incomplete stent apposition.

Background Endovascular coil embolization (ECE) for intracranial aneurysms has been proven as an effective minimally invasive treatment. However, the aneurysm recanalization after coiling is a serious complication of this technique. Among all the proposed factors associated with recanalization, the impact of packing density (PD) is still controversial. Objective To clarify the role of PD in the aneurysm recanalization following ECE, via conducting a systematic review and meta-analysis. Methods A systematic literature search was conducted using PubMed, Scopus, Embase, and Web of Science databases, until November 28, 2022, by adhering to the Preferred Reporting Items for Systematic Review and Meta-Analyses statement guidelines. Considering the eligibility criteria, all the studies reporting the outcomes of interest were included. Data elements of interest were extracted and analyzed using R software version 4.2.1. Results The pooled analysis of the 17 eligible papers revealed a 29% higher PD of the nonrecanalized aneurysms (ROM = 1.29, 95% confidence interval [CI] = 1.18–1.40, p < 0.001), even after removing outlier studies to reduce heterogeneity. However, the pooled estimates from multivariable regression models within nine included studies showed no significant effect of PD on recanalization odds when incorporated into a multivariable model with other predictors (odds ratio [OR] = 0.93, 95% CI = 0.84–1.02, p = 0.126), even after removing outlier studies. Conclusion The current literature does not support PD as a significant predictor of aneurysm treatment outcomes, especially with adjusting for other variables. This finding necessitates further prospective multicenter studies with a larger sample size to overcome the current methodological shortcomings.
