Brain surgery requires at most accuracy and precision, yet current neurosurgical robots are limited in their ability to reach intracranial regions due to their rigid and inflexible nature. However, Continuum robots have great potential and are currently helping to change the face of neurosurgery as we know it. They overcome the challenges of conventional tools by providing much greater flexibility and control, consequently reducing recovery times and improving patient outcomes. Continuum robots are a class of robots characterized by their higher number of degrees of freedom. This flexibility and maneuverability lead to the possibility of minimally invasive procedures which were not possible with conventional methods. This paper profoundly reviews the major research done in the field of continuum robots in neurosurgery and to provide a comparative analysis along with a discussion of the same. The review discusses the state of neurosurgery before continuum robots, the limitations of conventional tools, and why continuum robots are looking so promising for the future of neurosurgery. A detailed comparative analysis of existing research is tabulated to highlight the current challenges and future scope in the development and application of continuum robots in brain surgery.

Mixed-reality (MR) head-mounted displays (HMD) offer virtual augmentations registered with real objects, allowing for direct patient-centered lesion visualization. In contrast to other surgical subspecialties, however, the application of MR in neurosurgery remains poor. In this proof-of-concept study, we aimed at evaluating the applicability, educational value, and accuracy of HMD as compared to standard neuronavigation (SN) in the planning of treatment for patients undergoing neurovascular and tumor surgeries.
Methods
A 3D hologram of the patient’s anatomy was generated from conventional CT scan, MRI, and/or 3D rotational angiography (3D-RA), and integrated into the HMD. The participating surgeons completed a standardized questionnaire, which evaluated the application of HMD compared to SN, to detail the visualization benefits and limitations of the 3D hologram.
Results
Eight consecutive patients with neurovascular (n = 4) or tumor pathologies (n = 4) were selected for MR. The mean (±SD) setup time was significantly longer for HMD than SN (8.3 ± 1.5 min vs. 4.8 ± 1.3 min; p < 0.001), independent of the pathology applied (i.e., tumor: 8.0 ± 2.0 vs. 4.3 ± 1.3, p = 0.02, and vascular: 8.7 ± 0.9 vs. 5.4 ± 1.1; p < 0.001). Surgeons wearing the HMD succeeded in moving the 3D hologram from respective operators’ angles and identifying the shape and configuration of the lesion. The MR device was superior to SN with regard to treatment planning on account of its improved spatial awareness. The current method is however limited in its representation of small perforators in neurovascular pathologies and bony involvement in tumors.
Conclusions
MR may become a valuable tool in the preoperative treatment planning, education and guidance of complex procedures in selected patients, yet further development is necessary to improve the clinical applicability of the MR HMD.
目的混合现实(MR)头戴式显示器(HMD)提供与真实物体注册的虚拟增强,允许直接以患者为中心的病变可视化。然而,与其他外科专科相比,MR在神经外科中的应用仍然很差。在这项概念验证研究中,我们旨在评估HMD与标准神经导航(SN)相比在神经血管和肿瘤手术患者治疗计划中的适用性、教育价值和准确性。方法通过常规CT扫描、MRI和/或3D旋转血管造影(3D- ra)生成患者解剖结构的3D全息图,并将其整合到HMD中。参与的外科医生完成一份标准化问卷,评估HMD与SN的应用,详细说明3D全息图的可视化优势和局限性。结果连续8例有神经血管或肿瘤病变的患者(n = 4)进行mr, HMD的平均(±SD)建立时间明显长于SN(8.3±1.5 min vs 4.8±1.3 min);p & lt;0.001),与所应用的病理无关(即肿瘤:8.0±2.0 vs. 4.3±1.3,p = 0.02,血管:8.7±0.9 vs. 5.4±1.1;p & lt;0.001)。佩戴HMD的外科医生成功地从各自操作员的角度移动了3D全息图,并识别了病变的形状和结构。MR装置在治疗计划方面优于SN装置,其空间意识提高。然而,目前的方法在神经血管病变和肿瘤骨受累的小穿支的表现上是有限的。结论磁共振HMD可作为特定患者术前治疗计划、复杂手术教育和指导的有价值的工具,但仍需进一步提高磁共振HMD的临床适用性。

Background: Saccular aneurysms (SAs) have been long studied in hemodynamics using computational fluid dynamics (CFD), while dissecting aneurysms (DAs) remain unclear. To estimate which side of the aneurysm ruptured, we evaluated the hemodynamics of the bilateral vertebral artery DAs (VADAs).
Case presentation: A 44-year-old male was diagnosed with subarachnoid hemorrhage by the rupture of either side of bilateral VADAs. The rupture side could not be determined on admission (Day 0). CFD was performed using a patient-specific geometry model obtained from 3-demensional (3D) rotational angiography (RA) on day 1. We predicted that the right DA had ruptured based on the hemodynamics, associated with flow stagnation and complexity in the ruptured SAs by a transient analysis with the patient-specific blood flow velocity waveforms. After careful observation, gadolinium-enhanced MRI on day 16 showed a contrast effect in the right wall and a change in the right shape was confirmed on the second 3D RA on day 17. According to both imaging evaluations and CFD, the right was presumed to be ruptured, and a flow-diverter stent was placed at the right VA. The right VADA did not re-rupture for 12 months.
Conclusion: Our results indicated that hemodynamics of ruptured DAs would be similar to that of ruptured SAs.

Objective
Acute spontaneous intracerebral hemorrhage (ICH) is a life-threatening condition, and certain serological indicators may be associated with the prognosis after ICH. This study investigated the relationship between N-terminal pro-B-type natriuretic peptide (NT-pro-BNP) and other serological indicators with prognosis 90 days after the onset of acute ICH.
Methods
The general information, clinical, and follow-up data of patients with ICH who were admitted to the Department of Neurology, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology from January 2019 to September 2022 were retrospectively collected. Based on the modified Rankin Scale (mRS) at 90 days of onset, the patients were divided into poor prognosis group (mRS > 3) and good prognosis group (mRS ≤ 3), and the differences in various indicators between these two groups were compared. Serological indicators related to prognosis were determined by univariate and multivariate logistic regression analysis, and the predictive value was evaluated by receiver operating characteristic (ROC) analysis and decision curve analysis (DCA).
Results
A total of 121 patients with ICH were included in the study with 49 patients having a good prognosis and 72 patients having a poor prognosis. Multivariate logistic regression analysis showed that NT-pro-BNP at admission was associated with prognosis at 90 days after ICH onset (P < 0.05). ROC and DCA analyses demonstrated that NT-pro-BNP had a certain predictive ability for ICH prognosis.
Conclusions
The level of NT-pro-BNP at admission may be an independent risk factor for predicting prognosis at 90 days after the onset of ICH. The higher the level, the worse the prognosis may be.

Patients with malignant tumors face an elevated risk of cerebrovascular complications, such as intratumoral hemorrhage, tumor invasion into arterial and venous sinuses, leptomeningeal infiltration, and tumor embolism. This review examines the significant role and implications of cisplatin and radiation therapy in the development of these cerebrovascular complications, which can occur at various stages: before, during, or long after the completion of cancer treatment. Detailed clinical case studies of CNS involvement during oncological therapy are presented to illustrate these complications. The mechanisms by which cisplatin and radiation therapy contribute to cerebrovascular disorders are multifaceted. Cisplatin, a widely used chemotherapeutic agent, is associated with endothelial damage and thromboembolic events, while radiation therapy can cause vascular injury, leading to long-term changes in cerebral vasculature. These treatments, though effective in managing malignancies, pose significant risks to cerebrovascular health. The review underscores the diverse types and mechanisms of stroke encountered in cancer patients, influenced by tumor stage and pathological characteristics. These include ischemic stroke, hemorrhagic stroke, and transient ischemic attacks, each requiring specific diagnostic and therapeutic strategies. The interaction between cancer pathology and cerebrovascular health necessitates a multidisciplinary approach, integrating oncology, neurology, radiology, and vascular surgery. Such an approach is crucial for effective management and prognosis evaluation in this patient population. Early recognition and intervention are paramount to mitigating risks and improving outcomes. By understanding these complex interactions, healthcare providers can better anticipate and manage cerebrovascular risks in patients undergoing cancer treatment. This comprehensive understanding helps in formulating personalized treatment plans, optimizing both oncological and neurological care, and ultimately enhancing patient quality of life and survival rates.

Intracerebral hemorrhage (ICH) represents a significant health challenge due to its high mortality and severe outcomes. Poly (ADP-ribose) polymerase (PARP) is a chromatin-associated nuclear protease, which would be activated by ROS derived from hematoma metabolites after ICH, and lead to parthanatos, a form of caspase-independent programmed cell necrosis. Recent evidence indicates that PARP activation plays a pivotal role in various human diseases, particularly neurodegenerative disorders, cerebral ischemia–reperfusion injury, and hemorrhagic transformation. However, the link between PARP activation and secondary brain injury (SBI) following ICH remains underexplored. This review delves into the pathological mechanisms of PARP activation in cell injury, with a focus on parthanatos, mitochondrial dysfunction, neuroinflammation, and blood–brain barrier (BBB) disruption after ICH. Understanding these processes may offer new insights into the role of PARP activation in ICH and pave the way for developing more effective therapeutic strategies.

Anterior cerebral artery (ACA) territory infarctions are relatively rare, accounting for 0.3 % to 4.4 % of stroke cases, with bilateral occurrences being even rarer. These infarctions can lead to quadriplegia/paresis. Bilateral ACA territory infarctions are possibly caused by vasospasm due to subarachnoid haemorrhage (SAH) from ruptured anterior communicating artery (ACoA) aneurysms or thrombosis in the presence of a rudimentary contralateral artery. ACoA aneurysm with quadriparesis is extremely unusual, with this being only the second recorded occurrence and the youngest reported. Overall, understanding the mechanisms and consequences of ACA territory infarctions, especially bilateral occurrences, remains crucial for effective diagnosis and management of such rare but serious neurological events.
Case Presentation
A 35-year-old male, previously healthy, presented with quadriparesis and an ACoA aneurysm. Initially experiencing a headache and brief loss of consciousness, he later developed right foot drop and progressive right-sided weakness, leading to altered consciousness. Subsequent imaging revealed SAH consistent with the aneurysm and also bilateral ACA territory infractions. Upon referral for further management, he presented with intact higher mental functions but motor deficits in the upper and lower limbs. Imaging and assessments confirmed the diagnosis, prompting a decision for craniotomy and clipping. Postoperatively, the patient showed improvement, with enhanced power in both upper limbs at one-month follow-up.
Conclusion
Bilateral ACA territory infarction is unusual, and the symptoms are not yet well understood. ACoA aneurysm with quadriparesis is extremely unusual. Understanding the mechanics and clinical consequences of bilateral ACA territory infarctions is critical for early detection and management.

Objective
The purposes of this study were to retrospectively review mid-term outcomes of stent-assisted coil embolization for acutely ruptured cerebral aneurysms, and to identify risk factors.
Methods
Between April 2013 and October 2018, thirty-four consecutive patients had stent-assisted coil embolization for treatment of acutely ruptured cerebral aneurysms that were not amendable by simple coiling. Hospital subarachnoid hemorrhage registry and notes on hospital electronic medical systems were retrospectively reviewed. All patients had a dose of intravenous abciximab 10 mg and heparin 2000 units before stenting and started dual antiplatelet therapy after procedure.
Results
Of the thirty-four consecutive patients, twenty-six (76 %) were treated with braided stents and eight (24 %) were treated with laser-cut stents. There was no rebleeding in thirty-two patients who achieved total aneurysmal occlusion or residual neck only. Rebleeding occurred in two patients who only achieved partial embolization, resulting in mortality. There were three (9 %) thromboembolic complications, in which two were ADL-independent upon hospital discharge and the one with WFNS Grade V succumbed. Twenty (59 %) patients achieved clinical favorable outcomes (mRS 0–2) at follow-up (mean+/-SD: 17+/-15 months). The need of EVD insertion was a statistically significant risk factor for procedure-related cerebral infarction, intracerebral hemorrhage and 30-day mortality. The GOS and mRS were closely related to the need of EVD insertion and sidewall location of aneurysm.
Conclusions
The study established the efficacy and safety profile of stent-assisted embolization for treatment acutely ruptured cerebral aneurysms. The embolization goal should be total aneurysmal occlusion or with minimal residual neck to prevent rebleeding and reduce mortality. The use of such technique should be considered when simple coiling or microsurgical clipping is not feasible or suitable. The need of EVD insertion is an independent risk factor for intracerebral hematoma and 30-day mortality. When needed, EVD insertion shall be considered before antiplatelet agents, and require exceptionally meticulous hemostasis intraoperatively.
