[PMID: 39067369 DOI: 10.1016/j.jocn.2024.110766] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2024] [Revised: 07/20/2024] [Accepted: 07/22/2024] [Indexed: 07/30/2024]
Abstract
INTRODUCTION Small and very small anterior communicating artery (ACoA) aneurysms pose a complex challenge in neurosurgery and interventional neuroradiology due to their critical location and potential for severe consequences upon rupture. Surgical clipping has been a traditional approach, but it presents challenges requiring precision and expertise. Endovascular treatment has emerged as an alternative, offering minimally invasive techniques with potential advantages. This study aims to comprehensively compare outcomes and efficacy between surgical clipping and endovascular treatment for small or very small ACoA aneurysms. OBJECTIVES We aimed to perform a meta-analysis of small or very small anterior communicating artery aneurysms comparing surgical clipping and endovascular treatments. METHODS A systematic review and meta-analysis were conducted, including studies reporting on both treatment modalities. Eligible studies were identified through PubMed, Cochrane Library, and Embase databases. Pooled analyses with 95% confidence intervals were used to compare treatment effects, and statistical analysis followed PRISMA guidelines. RESULTS Thirteen studies with 637 patients were included. Endovascular treatment, predominantly coiling, was performed in 60.3% of patients, while 39.7% underwent surgical management. Endovascular treatment exhibited an 18% retreatment rate, contrasting with 0% in the surgery group. Mortality rates were 3% and 6% for endovascular and surgical treatments, respectively. Overall complications occurred in 1.8% of patients, with intraoperative rupture and cerebral infarction being the most common. CONCLUSION In summary, our study indicates a comparable outcome between surgical clipping and endovascular treatment for small ACoA aneurysms, with the former showing a lower retreatment rate. Decision factors include surgeon expertise, healthcare context, and patient age. Further research is needed to refine treatment strategies, considering variations in aneurysm status and evolving techniques.

Endovascular Coiling of Ruptured Tiny Saccular Intracranial Aneurysms: A Systematic Review and Meta-Analysis. World Neurosurg 2024; 187:e414-e446. [PMID: 38663736 DOI: 10.1016/j.wneu.2024.04.100] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2024] [Accepted: 04/16/2024] [Indexed: 05/27/2024]
Abstract
BACKGROUND The safety and efficacy of endovascular coiling of ruptured tiny saccular intracranial aneurysms (IAs) (≤3 mm) remain unknown. METHODS A comprehensive search of PubMed, Embase, Web of Science, and Scorpus databases up to November 15, 2023 was performed. Pooled prevalence was calculated for occlusion rates, recanalization, retreatment, long-term favorable outcome, and procedure-related complications and mortality. Pooled odds ratios were calculated to compare these outcomes between coiling and stent-assisted coiling (SAC). RESULTS Forty-two studies with 2166 ruptured tiny saccular IAs treated with coiling were included. The follow-up complete aneurysm occlusion rate was 83.9% (95% CI: 77.2-88.9%). The rates of recanalization and retreatment were 7.7% (95% CI: 5.7-10.2%) and 5.8% (95% CI: 4.5-7.5%). The range of median Hunt and Hess grades was 1.4-2.9 and the favorable outcome rate was 85.6% (95% CI: 81.1-89.2%). The rates of thromboembolism, intraprocedural rupture, and mortality were 4.6% (95% CI: 3.6-5.8%), 5.4% (95% CI: 4.1-7.0%), and 5.6% (95% CI: 4.4-7.2%), respectively. Comparison of coiling and SAC revealed no significant difference, except for a higher likelihood of follow-up complete aneurysm occlusion in SAC (odds ratio [OR] 0.37, 95% CI: 0.17-0.80) and recanalization in the coiling (OR, 3.21 [95% CI, 1.37-7.51]). CONCLUSIONS Our meta-analysis demonstrates that coiling for ruptured tiny saccular IA is a feasible, effective, and safe approach that is associated with favorable clinical outcomes in both the short and long term for patients with mild to moderate Hunt and Hess grades.

World Neurosurg 2023; 173:e391-e400. [PMID: 36803690 DOI: 10.1016/j.wneu.2023.02.061] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2022] [Revised: 02/10/2023] [Accepted: 02/11/2023] [Indexed: 02/19/2023]
Abstract
OBJECTIVE To establish and validate a risk prediction model for perioperative ischemic complication (PIC) of endovascular treatment for ruptured anterior communicating artery aneurysms (ACoAAs). METHODS The general clinical and morphologic data, operation schemes, and treatment outcomes of patients with ruptured ACoAAs treated with endovascular treatment in our center from January 2010 to January 2021 were retrospectively analyzed and assigned to primary (359 patients) and validation (67 patients) cohorts. A risk-predicted nomogram for PIC was developed through multivariate logistic regression analysis in the primary cohort. The discrimination ability, calibration accuracy, and clinical usefulness of the established PIC prediction model were evaluated and verified based on the receiver operating characteristic curves, calibration curves, and decision curve analysis in the primary and external validation cohorts, respectively. RESULTS A total of 426 patients were included, 47 of whom had PIC. The multivariate logistic regression analysis showed that hypertension, Fisher grade, A1 conformation, use of stent-assisted coiling, and aneurysm orientation were independent risk factors for PIC. Then, we developed a simple and easy-to-use nomogram to predict PIC. This nomogram has a good diagnostic performance (area under the curve, 0.773; 95% confidence interval, 0.685-0.862) and calibration accuracy; we then further validated this nomogram by external validation cohort and showed an excellent diagnostic performance and calibration accuracy. Besides, the decision curve analysis confirmed the clinical usefulness of the nomogram. CONCLUSIONS A history of hypertension, high preoperative Fisher grade, complete A1 conformation, use of stent-assisted coiling, and aneurysm orientation (pointing upward) are risk factors for PIC for ruptured ACoAAs. This novel nomogram might serve as a potential early warning sign of PIC for ruptured ACoAAs.

Abstract
Previously, anterior communicating artery aneurysms were considered unsuitable for endovascular treatment. In recent years, however, endovascular treatment has been increasingly performed due to the fact that it is less likely to cause high dysfunction compared to surgery and the treatment has been improved. The International Subarachnoid Aneurysm Trial reported anterior communicating artery aneurysms comprise 45.4% of cerebral aneurysms on which both endovascular treatment and surgery are suitable. The use of the endovascular treatment for anterior communicating artery aneurysms is expected to increase in the future. In this paper, we present cases from our institution based on the characteristics of anterior and distal communicating artery aneurysms, treatment strategies, and treatment indications.

The Safety and Efficacy of Endovascular Treatment for Very Small Ruptured Anterior Communicating Artery Aneurysms: A Large Single-Center Experience With 81 Consecutive Cases. World Neurosurg 2021; 152:e576-e582. [PMID: 34133994 DOI: 10.1016/j.wneu.2021.06.025] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2021] [Revised: 05/31/2021] [Accepted: 06/02/2021] [Indexed: 11/21/2022]
Abstract
OBJECTIVE This study aimed to investigate the safety and efficacy of endovascular embolization for very small ruptured anterior communicating artery (AcomA) aneurysms. METHODS From August 2015 to June 2020, 81 patients with very small (≤3 mm) ruptured AcomA aneurysms treated endovascularly were enrolled in this study. Clinical and radiographic data were analyzed retrospectively, including the aneurysm occlusion rate, complications, and clinical outcome. RESULTS Among 81 patients, simple coiling embolization was performed in 52 cases and stent-assisted embolization in 29 cases. Immediate angiography demonstrated complete occlusion in 59 (72.8%) aneurysms, residual neck in 20 (24.7%) aneurysms, and residual lumen in 2 (2.5%). Procedure-related complications rate was 2.5% (2 of 81), all of which were transient thromboembolic events. Angiographic follow-up outcomes of 60 patients (mean: 6.8 ± 3.2 months) revealed complete occlusion in 91.7% (55 of 60), with recurrence in 1 patient. The mean clinical follow-up time was 22.6 ± 11.4 months and good prognosis rates (6-month modified Rankin Scale score: 0-2) reached 90.2% (73 of 81). The differences in aneurysm occlusion and procedure-related complications between the simple coiling group and the stent-assisted coiling group were not statistically significant. CONCLUSIONS Coiling with or without stent-assisted technique for the treatment of very small ruptured AcomA aneurysms was safe and effective.

Abstract
BACKGROUND AND PURPOSE The Woven EndoBridge (WEB) device is an established technique for the treatment of intracranial aneurysms. Occasionally, persistent opacification inside the WEB lumen can be observed at follow-up (previously described as Bicêtre Occlusion Scale Score 1). We evaluated potential risk factors of this phenomenon, hypothesizing that initial deviation of the WEB device from the aneurysm axis, size of the aneurysmal neck surface, or inappropriate WEB sizing correlates with Bicêtre Occlusion Scale Score 1 findings. MATERIALS AND METHODS We systematically reviewed all patients treated with the WEB device between February 2014 and December 2018 in our neurointerventional center. Patients with midterm follow-up DSA available were considered for aneurysm evaluation applying the Bicêtre Occlusion Scale Score. WEB angle deviation from the aneurysm axis, neck widths, and WEB sizes were collected. RESULTS We included 65 patients with 67 intracranial aneurysms. Eleven of 67 (16.4%) intracranial aneurysms showed the Bicêtre Occlusion Scale Score 1 phenomenon at follow-up. Anterior-posterior projections of WEB axis deviation (angles measured in degrees) were significantly different between the Bicêtre Occlusion Scale Score 1 cohort (median ± interquartile range, 17 ± 17) and all other Bicêtre Occlusion Scale Scores (median ± interquartile range, 7 ± 11; P = .023), whereas in lateral projections, no significant difference was observed (median ± interquartile range, 10 ± 10 versus 8 ± 9; P = .169). Neck or aneurysm recurrence, but not the Bicêtre Occlusion Scale Score 1 phenomenon, occurred significantly more often in patients with inappropriate WEB sizing compared with appropriate WEB sizing (median ± interquartile range, 1 ± 1.3 versus 0 ± 0; P < .001/P = .664). CONCLUSIONS The Bicêtre Occlusion Scale Score 1 phenomenon is associated with an initial deviation of the WEB device from the aneurysm axis but does not correlate with aneurysmal neck surface measurements or WEB sizing.

Abstract
OBJECTIVE The term anterior communicating (ACom) aneurysm is often broadly used to classify any aneurysm formed on the A1-A2 junction, A1, A2, or ACom arteries. Aneurysm location has been associated with rupture risk, so whether an aneurysm is truly formed on the ACom artery can critically affect treatment decisions. The aim of this study was to reclassify broadly termed ACom aneurysms into 4 subgroups (A1, A2, true ACom, and A1-A2 junction) based on their location. METHODS A retrospective, pilot study was conducted to identify all consecutive patients with ACom aneurysm managed over the past 4 years in a single center. Using computed tomography angiography, aneurysms were classified into 1 of the 4 subgroups. Additional information was collected on patient demographics, subarachnoid hemorrhages, projections of aneurysm dome, and aneurysm diameter. RESULTS A total of 48 aneurysms with available computed tomography angiography imaging were included in the final analysis. The reclassification of ACom aneurysms into subgroups resulted in 40 A1-A2 junction, 6 true ACom, 2 A2, and zero A1 aneurysms. A total of 100% versus 80% of true ACom and A1-A2 junction aneurysms ruptured, respectively. All elective coiling procedures were performed on unruptured A1-A2 junction aneurysms. CONCLUSIONS We found only 13% of the aneurysms initially referred to as ACom to be true ACom aneurysms. A more nuanced approach to ACom aneurysm classification may better guide management strategies.
