Background: Randomized controlled trials demonstrate that endovascular techniques yield improved outcomes compared with microsurgical approaches. However, not all patients are suitable candidates for endovascular management. This study aimed to determine if healthy patients managed microsurgically could achieve functional outcomes comparable to patients managed endovascularly.
Methods: Patients treated for ruptured aneurysmal subarachnoid hemorrhage at 2 level 1 stroke centers from January 2012 through December 2020 were retrospectively reviewed. All cases were evaluated in an endovascular right of first refusal neurosurgical environment. We collected relevant clinical and follow-up data and created a generalized linear model to identify differences between patients treated endovascularly versus microsurgically. A propensity score model accounting for these differences was used to predict patient outcomes. Functional outcomes were independently assessed using the modified Rankin Scale (mRS) with good functional outcome defined as modified Rankin Scale score <3.
Results: The study included 588 patients (211 microsurgical, 377 endovascular); median age was 58 years (interquartile range: 40-86 years); in-hospital mortality was 13%. Age, aneurysm size, and aneurysm location significantly predicted treatment modality (all P < 0.05). After greedy-type matching (210 microsurgical, 210 endovascular), patients managed microsurgically were less likely to be discharged home (odds ratio = 0.6, 95% confidence interval 0.4-0.9, P = 0.01). Functional differences disappeared over time; patients in the 2 treatment arms had similar functional outcomes at 3 months (odds ratio = 1.1, 95% confidence interval 0.7-1.8, P = 0.66) and 1 year after subarachnoid hemorrhage (odds ratio = 1.3, 95% confidence interval 0.8-2.1, P = 0.38).
Conclusions: In an endovascular right of first refusal neurosurgical environment, practitioners can treat patients who are not good endovascular candidates microsurgically and achieve functional outcomes comparable to patients managed endovascularly.

Three monoclonal antibodies directed against specific forms of the amyloid-β (Aβ) peptide have been granted accelerated or traditional approval by the FDA as treatments for Alzheimer disease, representing the first step towards bringing disease-modifying treatments for this disease into clinical practice. Here, we review the detection, underlying pathophysiological mechanisms and clinical implications of amyloid-related imaging abnormalities (ARIA), the most impactful adverse effect of anti-Aβ immunotherapy. ARIA appears as regions of oedema or effusions (ARIA-E) in brain parenchyma or sulci or as haemorrhagic lesions (ARIA-H) in the form of cerebral microbleeds, convexity subarachnoid haemorrhage, cortical superficial siderosis or intracerebral haemorrhage.

Objective: Aneurysmal subarachnoid hemorrhage (SAH) is associated with high morbidity and mortality rates. In particular, functional outcomes of SAH caused by large or giant (≥ 10 mm) ruptured intracranial aneurysms are worsened by high procedure-related complication rates. However, studies describing the risk factors for poor functional outcomes specific to ruptured large/giant aneurysms are sparse.

Although many institutions increasingly perform endovascular coiling instead of microsurgical clipping as the primary treatment for ruptured aneurysms, there remains ongoing debate regarding the optimal treatment strategy for ruptured middle cerebral artery (MCA) aneurysms. Therefore, we compared the outcomes of clipping and coiling for treating ruptured MCA aneurysms. A total of 155 ruptured MCA aneurysms that were deemed eligible for both clipping and coiling were retrospectively reviewed.

To evaluate the safety and efficacy of staged coiling followed by flow diverter (FD) in the treatment of ruptured intracranial aneurysms(RIAs). A retrospective analysis was conducted on 20 patients with RIAs treated with staged coiling followed by FD at a single center, between April 2015 and September 2024. Patient demographics, aneurysm characteristics, clinical and imaging outcomes were reviewed.
