Abstract
OBJECTIVE Aneurysmal subarachnoid hemorrhage (aSAH) is associated with high mortality rates. There is a significant gap in the literature describing global disparities in demographics, management, and outcomes among patients with aSAH. We aimed to conduct a systematic review and meta-analysis to assess global disparities in aSAH presentation and management. METHODS PubMed and Embase databases were queried from earliest records to November 2022 for aSAH literature. Presentation, demographics, comorbidities, treatment methods, and outcomes data were collected. Articles that did not report aSAH-specific patient management and outcomes were excluded. Pooled weighted prevalence rates were calculated. Random effects model rates were reported. RESULTS After screening, 33 articles representing 10,553 patients were included. The prevalence of Fisher grade 3 or 4 aSAH in high- and lower-income countries (HIC and LIC), respectively, was 79.8% (P < 0.01) and 84.1 (P < 0.01). Prevalence of male aSAH patients in HIC and LIC, respectively, was 35.8% (P < 0.01) and 45.0% (P < 0.01). Prevalence of treatment in aSAH patients was 99.5% (P < 0.01) and 99.4% (P = 0.16) in HIC and LIC, respectively. In HIC, 35% (P < 0.01) of aneurysms in aSAH patients were treated with coiling. No LIC reported coiling for aSAH treatment; LIC only reported rates of surgical clipping, with a total prevalence of 92.4% (P < 0.01) versus 65.6% (P < 0.01) in HIC. CONCLUSION In this analysis, we found similar rates of high-grade SAH hemorrhages in HIC and LIC but a lack of endovascular coil embolization treatments reported in LIC. Additional research and discussion are needed to identify reasons for treatment disparities and intervenable societal factors to improve aSAH outcomes worldwide.

Abstract
Objective: The mortality of rebleeding after ruptured intracranial aneurysms was more than 40%. It is essential to identify the intracranial artery in sectional anatomy. However, it is difficult for students to understand the intracranial artery in the section. Therefore, the
purpose of this study is to explore the application effect of three-dimensional (3D) reconstruction and numerical simulation of intracranial aneurysm for sectional anatomy based on computed tomography angiography (CTA). Method: Sixty students in medical imaging specialty of our university
were divided into two groups. The control group was taught with conventional sectional anatomy and CT images, while the observation group was taught with 3D reconstruction and numerical simulation of intracranial aneurysm. The teaching characteristics and teaching effects were analyzed and
compared between the two groups. Result: The 3D reconstruction can accurately express the size, direction, and adjacent relationship of aneurysms. Through rotation of the 3D image, students can easily understand the name and location of cerebral arteries. Combined with the function
of 3D positioning, each blood vessel can automatically and accurately locate in the transverse, coronal, and sagittal plane. Abnormal wall shear stress was easily found in the intersection of cerebral artery circle, which was the physiological basis for the occurrence of aneurysms. There was
a high shear zone in the root of an aneurysm, which was the physiological factor of rupture. The scores of sectional specimen identification, drawing examination, and theoretical assessment in the observation group were significantly higher than those in the control group (P < 0.05).
Conclusion: The 3D reconstruction and numerical simulation can directly display the 3D morphological and physiological characteristics of intracranial aneurysms, which is convenient for students to understand and memorize. It can reach a good teaching effect in sectional anatomy.

Microsurgical and endovascular treatment of un-ruptured cerebral aneurysms by European hybrid neurosurgeons to balance surgical skills and medical staff management. Acta Neurochir (Wien) 2021; 163:1515-1524. [PMID: 33564907 PMCID: PMC8053657 DOI: 10.1007/s00701-021-04746-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2020] [Accepted: 01/27/2021] [Indexed: 12/01/2022]
Abstract
Background In Europe, aneurysm treatment performed by dually trained neurosurgeons is extremely scarce. We provide outcome data for un-ruptured aneurysm patients treated at a European hybrid center to prove that hybrid neurosurgeons achieve clinical and angiographical results allowing to integrate hybrid neurosurgery into routine aneurysm treatment. This will not only help to maintain neurovascular microsurgical skills but will influence staff costs in related hospitals. Methods We retrospectively analyzed all consecutively treated un-ruptured aneurysm patients between 2000 and 2016. The decision-making took into account the pros and cons of both modalities and considered patient and aneurysm characteristics. Clinical outcome was assessed by the modified Rankin scale (mRS). Occlusion rates were stratified into grade I for 100%, grade II for 99–90%, and grade III for <90% occlusion. To account for the introduction of stents, two treatment periods (p1, 2000 to 2008; p2, 2009 to 2016) were defined. Results The study population consisted of 274 patients (median age 55 years) harboring 338 un-ruptured aneurysms. Microsurgery (MS) was performed in 51.8% and endovascular therapy (EVT) in 43.1%; 5.1% required combined treatment. Overall, 93% showed a favorable clinical outcome (mRS 0–2), 94.3% after MS and 91.5% after EVT. Grade I aneurysm occlusion was achieved in 82.6% patients, 91.9% after MS and 72.9% after EVT. Procedure-related complications occurred after MS in 5.6% and after EVT in 4.4% patients. Mortality was recorded for five (1.8%) patients, one patient after MS and four after EVT. For the EVT cohort, significant improvement from p1 to p2 was seen with clinical outcomes (P=0.030, RR = 0.905, CI: 0.8351–0.9802) and occlusion rates (P=0.039, RR = 0.6790, CI: 0.499–0.923). Conclusion Hybrid neurosurgeons achieve qualified clinical and angiographic results. Dual training will allow to maintain neurovascular caseloads and preserve future aneurysm treatment within neurosurgery. Furthermore economic benefits could be observed in hospital management.

Abstract
Neurogenic pulmonary edema (NPE) following acute stroke is an acute respiratory distress syndrome (ARDS) with clinical characteristics that include acute onset, apparent pulmonary interstitial fluid infiltration and rapid resolution. The pathological process of NPE centers on sympathetic stimulation and fulminant release of catecholamines, which cause contraction of resistance vessels. Elevated systemic resistance forces fluid into pulmonary circulation, while pulmonary circulation overload induces pulmonary capillary pressure that elevates, and in turn damages the alveolar capillary barrier. Damage to the alveolar capillary barrier leads to pulmonary ventilation disorder, blood perfusion disorder and oxygenation disorder. Eventually, NPE will cause post-stroke patients' prognosis to further deteriorate. At present, we lack specific biological diagnostic indicators and a meticulously unified diagnostic criterion, and this results in a situation in which many patients are not recognized quickly and/or diagnosed accurately. There are no drugs that are effective against NPE. Therefore, understanding how to diagnose NPE early by identifying the risk factors and how to apply appropriate treatment to avoid a deteriorating prognosis are important scientific goals. We will elaborate the progress of NPE after acute stroke in terms of its pathophysiological mechanisms, etiology, epidemiology, clinical diagnosis and early prediction, comprehensive treatment strategies, and novel drug development. We also propose our own thinking and prospects regarding NPE.

[PMID: 30790728 DOI: 10.1016/j.wneu.2019.02.004] [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: 12/01/2018] [Revised: 02/06/2019] [Accepted: 02/07/2019] [Indexed: 10/27/2022]
Abstract
OBJECTIVE To evaluate the safety and effectiveness of microsurgical clipping and endovascular embolization for the treatment of middle cerebral artery aneurysm (MCAA). MATERIAL AND METHODS The clinical data of 482 patients with MCAA treated with microsurgical clipping or endovascular embolization were analyzed retrospectively. According to whether the aneurysms were ruptured, patients were divided into a ruptured group and an unruptured group. Demographics, clinical manifestation, and postoperative complications were recorded. RESULTS In the microsurgical clipping group (257 patients), there were 114 male and 143 female patients. The mean age was (55 ± 10) years and the mean course of disease was 3 (1, 36) days. The total numbers of MCAA were 274, including 179 ruptured aneurysms and 95 unruptured aneurysms. In the endovascular embolization group (225 patients), there were 98 male and 127 female patients. The mean age was (54 ± 11) years and the mean course of disease was 10 (1, 55) days. The total numbers of MCAA were 234, including 126 ruptured aneurysms and 108 unruptured aneurysms. There was no difference between the incidence of complications in the ruptured and unruptured groups. The outcome of the endovascular embolization group was better than the microsurgical clipping group in ruptured aneurysms (P = 0.000). The recurrence rate of the endovascular embolization group was greater than the microsurgical clipping group in ruptured aneurysms (P = 0.023). CONCLUSIONS Both microsurgical clipping and endovascular embolization were safe and effective methods for the treatment of MCAA, but patients with ruptured MCAAs treated with endovascular embolization were more likely to experience recurrence.
