Abstract
BACKGROUND/PURPOSE Several periprocedural adjuncts for elective surgical aneurysm treatment have been introduced over the last 20 years to increase safety and efficacy. Besides the introduction of IONM in the late-1990s, ICG-videoangiography (ICG-VAG) since the mid-2000s and intraoperative CT-angiography/-perfusion (iCT-A/-P) since the mid-2010s are available. We aimed to clarify whether the introduction of ICG-VAG and iCT-A/-P resulted in our department in a stepwise improvement in the rate of radiologically detected postoperative ischemia, complete aneurysm occlusion and postoperative new deficits. METHODS Patients undergoing microsurgical clip occlusion for unruptured anterior circulation aneurysms between 2000 and 2019 were included, with ICG-VAG since 2009 and iCT-A/-P (for selected cases) since 2016. Baseline characteristics and treatment-related morbidity/outcome focusing on differences between the three distinct cohorts (cohort-I: pre-ICG-VAG-era, cohort-II: ICG-VAG-era, cohort-III: ICG-VAG&iCT-A/-P-era) were analyzed. RESULTS 1391 patients were enrolled (n = 74 were excluded), 779 patients were interventionally treated, 538 patients were surgically clipped by a specialized vascular team (cohort-I n = 167, cohort-II n = 284, cohort-III n = 87). Aneurysm size was larger in cohort-I (8.9 vs. 7.5/6.8 mm; p < 0.01) without differences concerning age (mean:55years), gender distribution (m: f = 1:2.6) and aneurysm location (MCA:61%, ICA:18%, ACA/AcomA:21%). There was a stepwise improvement in the rate of radiologically detected postoperative ischemia (16.2vs.12.0vs.8.0%; p = 0.161), complete aneurysm occlusion (68.3vs.83.6vs.91.0%; p < 0.01) and postoperative new deficits (10.8vs.7.7vs.5.7%; p = 0.335) from cohort-I to -III. After a mean follow-up of 12months, a median modified Rankin scale of 0 was achieved in all cohorts. DISCUSSION Associated with periprocedural technical achievements, surgical outcome in elective anterior circulation aneurysm surgery has improved in our service during the past 20 years.

Abstract
BACKGROUND The long-standing comparison between the endovascular and microsurgical treatment is still ongoing. While not any center avails of a neuroendovascular service, and not every aneurysm is suitable for endovascular treatment, the neurovascular technique is slowly disappearing from our territories, whereas in the current literature, the role of the neurosurgical treatment is being re-appreciated. The aim of this paper was to discuss a single surgeon's clinical and radiological results with the microsurgical management of unruptured intracranial aneurysms (UIA). METHODS We retrospectively reviewed the clinical and radiological records of patients treated for UIA, by a single surgeon, in the period ranging between 2015 and 2019. We recorded all the relevant anatomic features of the aneurysm, saliencies of the surgical treatment, such as the need for temporary clipping, intraoperative rupture, or postoperative complications. The results of the clinical and radiological follow-up examinations were recorded either. RESULTS Fifty-eight patient undergoing microsurgical clipping were included, harboring a total of 65 UIAs. CTA with 3D reconstructions was sufficient to reach a reliable preoperative planning in 46 patients (76%). A total of 94% of the cases were unchanged or neurologically unremarkable at follow-up. The presence of postoperative complications was associated to the neck size and predictor of a longer hospitalizations, as well as longer hospitalizations are associated to the patients' age, size of the aneurysms and surgical times. CONCLUSIONS According to our experience, we believe that microsurgical clipping plays a critical role in the management of UIA, also on the ground of the encouraging results of the relevant literature.

World Neurosurg 2023; 178:233-240.e13.

Abstract
BACKGROUND The decision for treatment for unruptured intracranial aneurysms (UIAs) is often difficult. Innovation in endovascular devices have improved the benefit-to-risk profile especially for elderly patients; however, the treatment guidelines from the past decade often recommend conservative management. It is unknown how these changes have affected the overall age of the patients selected for treatment. Herein, we aimed to study potential changes in the average age of the patients that are being treated over time. METHODS A systematic search of the literature was performed to identify all studies describing the age of the UIAs that were treated by any modality. Scatter diagrams with trend lines were used to plot the age of the patients treated over time and assess the presence of a potential significant trend via statistical correlation tests. RESULTS A total of 280 studies including 83,437 UIAs treated between 1987 and 2021 met all eligibility criteria and were entered in the analysis. Mean age of the patients was 55.5 years, and 70.7% were female. There was a significant increasing trend in the age of the treated patients over time (Spearman r: 0.250; P < 0.001), with a 1-year increase in the average age of the treated patients every 5 years since 1987. CONCLUSIONS The present study indicates that based on the treated UIA patient data published in the literature, older UIAs are being treated over time. This trend is likely driven by safer treatments while suggesting that re-evaluation of certain UIA treatment decision scores may be of great interest.

Abstract
Abstract
Background
Microsurgical clipping is effective for treating early rupture hemorrhage in intracranial aneurysm (IA) patients. We aimed to evaluate the therapeutic effects of microsurgical clipping at different time points on IA and to explore prognostic factors.
Methods
A total of 102 eligible patients were divided into good prognosis group (n = 87) and poor prognosis group (n = 15) according to Glasgow Outcome Scale (GOS) scores at discharge. The effects of microsurgical clipping at different time points (within 24 h, 48 h and 72 h) were compared. The incidence rates of postoperative complications in patients with different Hunt–Hess grades were compared. Prognostic factors were determined by multivariate logistic regression analysis. The nomogram prediction model was established based on independent risk factors and validated.
Results
The good recovery and success rates of complete aneurysm clipping were significantly higher in patients undergoing surgery within 24 h after rupture. The incidence rate of complications was significantly higher in patients with Hunt–Hess grade IV. Good and poor prognosis groups had significantly different age, history of hypertension, preoperative intracranial hematoma volume, aneurysm size, preoperative Hunt–Hess grade, later surgery, postoperative complications and National Institute of Health Stroke Scale (NIHSS) score, as independent risk factors for prognosis. The nomogram model predicted that poor prognosis rate was 14.71%.
Conclusion
Timing (within 24 h after rupture) microsurgical clipping benefits the prognosis of IA patients. Age, history of hypertension, preoperative intracranial hematoma volume, aneurysm size, preoperative Hunt–Hess grade, later surgery, postoperative complications and NIHSS score are independent risk factors for poor prognosis.
