In recent years, titles like "Direct Approach to the Anterior and Lateral Part of the Maxillary Sinus with an Endoscope (DALMA) " have become increasingly common at neurosurgery conferences. However, if DALMA is not performed correctly, external nasal deformities can occur. This section provides information to ensure that DALMA is performed safely and to help prevent complications. Next, the transcribriform approach is addressed. Since this study focuses on this approach, we describe the DRAF procedure and methods for crista galli resection. DRAF surgery, if not performed by surgeons with sufficient experience, may result in insufficient bone resection, thereby complicating surgical exposure. Furthermore, resection of the crista galli significantly improves the anterosuperior view, increases the mobility of the anterior skull base tissues, and ensures adequate working space. Here, we describe the surgical techniques developed or modified by the authors for these three approaches.

Endoscopic endonasal transsphenoidal surgery has become a cornerstone of minimally invasive skull base surgery, particularly for pituitary neuroendocrine tumors. Advances in endoscopic visualization, navigation systems, and surgical instruments have enabled safe and effective use of a direct transnasal corridor to the sella and adjacent skull base structures. However, successful execution of this approach requires a precise understanding of nasal and paranasal sinus anatomy, as well as meticulous surgical technique during the nasal and sphenoid phases of the procedure. This chapter describes the basic concepts and step-by-step techniques of the endoscopic endonasal transsphenoidal approach, with a special emphasis on nasal cavity expansion, sphenoid sinus access, and sellar floor opening. Key anatomical landmarks, including the lamellar concept of the ethmoid sinus, the sphenoid sinus natural ostium, and the relationship between the internal carotid artery and surrounding structures, are highlighted to enhance intraoperative orientation and safety. Practical guidance on mucosal incision, septal cartilage preservation, bone removal, and reconstruction strategies to prevent cerebrospinal fluid leakage is also provided. This chapter aims to establish a practical foundation for novice and intermediate surgeons, facilitating a safe transition to more advanced endoscopic skull base procedures through systematic anatomical understanding and standardized surgical techniques.

Endoscopic neurosurgery has advanced rapidly over the past three decades and now represents a core minimally invasive approach in modern neurosurgical practice. Despite technical progress, high-certainty evidence has often lagged, partly because outcome variability is driven not only by disease characteristics but also by procedure-specific complexity, surgeon proficiency, learning curves, and institution-dependent factors such as multidisciplinary team structure and perioperative workflows. This study provides a practical framework for building reproducible clinical evidence in endoscopic neurosurgery. We highlight (1) the design of high-quality clinical databases and the deliberate selection of electronic data capture (EDC) platforms to ensure standardization, completeness, auditability, and future reanalysis; (2) team-based infrastructure and governance, including clearly defined roles (e.g., surgeons, ENT collaborators, coordinators, data managers, biostatisticians) and multicenter mechanisms for oversight, data coordination, and formalized data-sharing agreements and quality-control procedures; and (3) analytical strategies for bias control, integrating appropriate statistical testing with survival analysis, multivariable modeling, propensity-based methods, effect size reporting, and learning-curve evaluation. By aligning robust data infrastructure, effective governance, and rigorous analytical methods, endoscopic neurosurgery can progress beyond anecdotal experience toward transparent, reproducible, and generalizable clinical evidence that informs clinical practice, training, and patient safety.

Neuroendoscopic intraventricular surgery provides a minimally invasive approach but is inherently challenging, as it is performed within a fragile, three-dimensional ventricular space while relying on a limited two-dimensional endoscopic view. Loss of orientation and subtle technical errors can result in hemorrhage or neural injury. This chapter describes practical strategies for achieving stable and reproducible neuroendoscopic intraventricular surgery, with emphasis on operating room setup, instrumentation, teamwork, and perioperative management. Key principles include aligning the surgeon, patient, and monitor to maintain visuomotor consistency; proactive use of navigation and intraoperative ultrasound to prevent misplacement; and gentle, deliberate manipulation of the vulnerability of ventricular structures. Instrument selection, including rigid scopes, channel-based rigid endoscopic systems, and coagulation-suction devices, is discussed from a safety-oriented perspective. A central emphasis is placed on the role of the assistant, whose responsibilities extend beyond irrigation control ( "water management" ) to include verbal cues and optimization of the surgical environment. Perioperative management, particularly external ventricular drainage (EVD) strategies, postoperative fever, and the role of neuroendoscopic ventricular irrigation in ventriculitis, are also reviewed. Collectively, these concepts highlight that successful neuroendoscopic surgery depends not only on technical proficiency but also on comprehensive surgical design and effective team coordination.

Endoscopic transsphenoidal surgery has been the most commonly performed neuroendoscopic procedure in Japan since its reimbursement category was introduced in 2012. Although the surgical technique is now largely standardized, perioperative management and operating room setup still vary among institutions. At our center, patients are positioned in a semi-Fowler's posture with the head elevated to reduce venous bleeding from the cavernous sinus, while carefully monitoring the risk of venous air embolism. A slight vertex-up angle facilitates a natural instrument trajectory and is adjusted according to lesion location. Surgery is performed using a four-hand technique, with the assistant controlling the endoscope and coordinating movements with the surgeon, adapting to anatomical constraints and the use of straight or angled endoscopes. We also describe our approach to perioperative glucocorticoid supplementation, postoperative endocrine management for pituitary disorders, and the prevention and treatment of delayed postoperative hyponatremia. Collaboration with otolaryngologists is preferred for postoperative nasal care. These strategies aim to enhance surgical safety, infection control, endocrine stability, and patient comfort while supporting continued advances in endoscopic skull base surgery.

Cerebral hemodynamics and metabolism are central to neurosurgical decision-making and directly influence management in cerebrovascular disease, revascularization, and perioperative care. Powers'classification offers a physiological basis for hemodynamic ischemia, and quantitative positron emission tomography remains the gold standard for evaluating cerebral blood flow, cerebral blood volume, oxygen extraction fraction, and the cerebral metabolic rate of oxygen. Single photon emission computed tomography with acetazolamide, computed tomography/magnetic resonance perfusion, and arterial spin labeling have improved clinical accessibility and allow assessment of cerebrovascular reserve, time-to-peak, mean transit time, and time-to-maximum. In acute ischemic stroke, perfusion imaging has advanced treatment selection from a time-based to a tissue-based paradigm, supporting thrombectomy in patients with large ischemic cores. Post-recanalization phenomena, including hyperperfusion and no-reflow, illustrate the complexity of microcirculatory dynamics. Perfusion studies also inform decisions in bypass surgery and carotid revascularization. For neurosurgeons, understanding these modalities and their complementary interpretations is essential for safe and effective practice. Future integration of imaging metrics with physiological data through artificial intelligence may facilitate patient-specific strategies, standardized protocols, multicenter validation, and ultimately reduce complications while improving outcomes.

In recent years, neuroendovascular therapy has advanced rapidly, enabling precise and minimally invasive treatments. A major driving force behind this progress is the evolution of devices, such as microcatheters, microwires, coils, and flow diverters. Understanding the specific characteristics of these devices and their appropriate use is essential to achieve optimal clinical outcomes. Current understanding is largely based on package inserts, manufacturing materials, schematic illustrations, and optical microscopy images. However, as these devices are extremely small, their true structural details are difficult to visualize. This article presents the direct observations of neuroendovascular devices using scanning electron microscopy, providing insights into their microscale architecture. By re-evaluating the device characteristics from this microscopic perspective, we aim to clarify their clinical significance and enhance understanding of device selection in neuroendovascular practice.

Device selection in neuroendovascular therapy has traditionally relied on operator experience and institutional routines, leading to variability and limited reproducibility. Advances in artificial intelligence (AI), particularly machine learning, now allow analysis of complex clinical and morphological data to support optimal device selection. AI can visualize and share tacit expert knowledge, enhance decision-making, and promote procedural standardization and education. However, its recommendations remain probabilistic, and final clinical responsibility must rest with the physician. Reliable application requires adequate multi-institutional data and improved interpretability. In addition to supporting clinical judgment, AI-based prediction can optimize medical device logistics by forecasting necessary items and reducing excessive deliveries and returns. Such efficiency is increasingly important in the context of workforce shortages and transportation constraints, including Japan's "2024 logistics problem." We developed an integrated system combining AI-driven device selection with an electronic ordering platform, enabling real-time information sharing among physicians, distributors, and logistics providers. In preliminary validation involving unruptured aneurysm cases, this approach reduced delivered items by 20-55% without compromising safety. AI-assisted device selection therefore represents both a clinical advancement and a pathway toward more sustainable medical supply chains, linking healthcare, industry, and logistics through data-driven optimization.

Rapid advances in catheter technologies, devices, and imaging techniques have broadened the range of cerebrovascular disorders that can be treated with neuroendovascular therapy. The indications for treating cerebral aneurysms have expanded with the introduction of distal access catheters, trans-radial devices, and innovations such as neck-bridge stents, flow diverters, and intrasaccular devices. Although these developments have increased therapeutic options, they have also introduced new complications and clinical challenges. Neurophysiological monitoring has long been used in cerebrovascular and intracranial tumor surgery to detect motor, sensory, and visual dysfunction. More recently, its application to neuroendovascular procedures has enabled real-time assessment of brain function during the procedure. Growing evidence indicates that such monitoring may help prevent neurological injury and improve outcomes. This article summarizes current knowledge and emerging challenges in neurophysiological monitoring for neuroendovascular therapy, with emphasis on cerebral aneurysm embolization.

Endovascular treatment for cerebrovascular disease relies on close collaboration among physicians, nurses, and radiologic technologists. A basic understanding of devices is essential for safe and efficient procedures. This review summarizes key concepts of vascular access routes and commonly used devices from the perspective of nurses and technologists working in neuroangiography suites. First, we outline the selection of arterial and venous access, including transfemoral and transradial approaches, with attention to aortic arch variants, upper-extremity arterial anatomy, and patient factors that influence the puncture site and postprocedural care. Next, we describe the structure and roles of introducer sheaths, guiding and intermediate catheters, high-flow microcatheters, and rotating or push-type hemostatic valves, highlighting how coaxial and triaxial systems support device stability. Finally, we review hemostatic devices for access-site closure and practical aspects of contrast injectors, such as pressure limits, contrast dilution, and selection of contrast media to balance image quality with pain reduction and contrast load. The goal of organizing these foundational topics is to support team-based neuroendovascular practice and facilitate communication among all staff involved in these increasingly complex procedures.

Middle meningeal artery embolization (MMAE) has emerged as an important endovascular intervention, though its applications differs between meningiomas and chronic subdural hematomas (CSDH). For meningiomas, MMAE serves as a preoperative adjunct aimed at tumor devascularization and softening to facilitate resection. However, given conflicting evidence regarding its ability to reduce blood loss, careful case selection based on tumor characteristics is essential. Conversely, for CSDH, MMAE targets the inhibition of membrane neovascularization to prevent hematoma recurrence. Recent randomized controlled trials have demonstrated its efficacy as an adjunct to standard treatment, while its role as a standalone treatment continues to show promise. Technical safety relies on a thorough understanding of "dangerous anastomoses" to prevent complications. Furthermore, the transradial approach is highlighted as a viable access route, offering reduced puncture-site complications, particularly for the elderly demographic common to these conditions. This article reviews the current evidence, technical considerations, and future perspectives of MMAE, emphasizing that optimized patient selection is paramount for maximizing therapeutic benefit in both conditions.

Transarterial embolization (TAE) of dural arteriovenous fistulas (DAVFs) has evolved significantly following insurance approval of liquid embolic agents such as Onyx and Histoacryl (n-butyl-2-cyanoacrylate[NBCA]). Onyx allows prolonged injection and controlled penetration into the venous side, whereas NBCA offers rapid polymerization and thrombogenicity. The success of TAE depends on the selection of appropriate delivery devices. The ultra-fine microcatheter, DeFrictor nano, provides superior distal access to small feeders near the shunt point, thereby facilitating effective embolization. In cases where the affected sinus serves as a normal venous drainage route, sinus protection balloon-assisted TAE is useful for achieving both shunt occlusion and preservation of venous function. This technique allows retrograde embolization of multiple feeders through the venous side. Understanding the characteristics of various liquid embolic agents and specialized devices is essential for achieving complete cure and preventing recurrence. This review discusses the latest devices and effective strategies for TAE of DAVFs.

When approaching an occluded sinus during transvenous embolization of dural arteriovenous fistulas, it is important to employ a combination of appropriate guiding and distal access catheters to ensure adequate support and effective navigation. When navigating a long and tortuous venous route, careful attention must be given to the backup support and lengths of the coaxial catheters and connectors. Effective embolization can be achieved by selecting coils according to the stage of the embolization procedure and using liquid embolic agents when indicated.

Cerebral vascular surgery for cerebral arteriovenous malformations (cAVMs) is often challenging due to the diversity of lesions. I describe my treatment policy, embolization techniques, selection of embolic substances, and device choice. Proper use of embolization techniques is critical for safety in cAVM procedures. I use coils, NBCA, and Onyx. NBCA is employed when short-distance, reliable feeder occlusion is required. I prefer microcatheters with good contrast properties that are compatible with coils; for very thin feeders, I select microcatheter with a finer diameter. In cAVM embolization, "how to use" is more important than "what to use." I define the purpose of embolization and select the technique and material for each case.

Transcarotid artery revascularization (TCAR) is a hybrid technique that incorporates features of both carotid endarterectomy (CEA) and carotid artery stenting (CAS). In this procedure, the common carotid artery is directly exposed and punctured under visualization to allow precise stent placement. Since its approval in the United States in 2015, TCAR has become an important treatment option for cervical internal carotid artery stenosis. Although many studies have reported favorable outcomes with TCAR, the overall level of supporting scientific evidence remains limited. CEA is still regarded as the evidence-based standard treatment for carotid artery stenosis, and its significantly lower cost compared with TCAR or CAS is considered another barrier to wider TCAR adoption. Given this background, the introduction of TCAR in Japan-where the clinical outcomes of CAS have been excellent-is of great interest. Moving forward, it will be important to monitor how patient selection criteria and clinical indications for TCAR are defined and how the procedure is ultimately incorporated into routine clinical practice.

Carotid artery stenting (CAS) has advanced through improvements in devices, refinement of techniques, and better patient selection. Understanding the characteristics and appropriate use of each device is essential for maximizing procedural safety and outcomes. This review summarizes the features of major devices used in CAS-including balloon-guiding catheters, angioplasty balloons, distal embolic protection devices, and carotid stents-and discusses practical strategies for device selection based on lesion morphology and clinical context. In addition, we describe several technical tips and institutional approaches that have contributed to more stable and reproducible results in our practice. Although detailed troubleshooting and rare complications could not be fully covered due to space limitations, awareness of device behavior and potential pitfalls is crucial for preventing perioperative ischemic events. We hope this review helps clinicians refine their procedural strategies and contributes to further reductions in CAS-related complications.

A balloon guide catheter (BGC) is commonly used for thrombectomy in acute ischemic stroke (AIS) of the anterior circulation. However, the findings supporting BGC usage remain unclear. The primary purpose of BGC use is preventing embolization in a new area; the BCG is also used as a balloon expansion technique to anchor devices during navigation and delivery to distal vessels. Conventional guide catheters are often used in cases of posterior circulation occlusion or with a transradial approach. Balloon and conventional guide catheters are reviewed, providing evidence supporting their use in treating AIS, describing the characteristics of each, and outlining guidelines for selecting the most appropriate guide catheter.

ASTER and ASTER 2 trials revealed no significant difference in clinical outcomes between stent retrievers (SR) and aspiration catheters (AC) and SR and combined technique for mechanical thrombectomy. Clinically, selecting an appropriate device should be individualized based on patient characteristics, underlying pathology, and operator expertise. A comprehensive understanding of device-specific technical features is essential to achieve a personalized and effective endovascular strategy. For SRs, this includes recognizing the "sweet spots" unique to each device. For ACs, operators must consider the inner and outer diameters and select the device based on precise measurement of the narrowest segment along the access route to ensure optimal navigation and firm engagement with the thrombus. Here, we provide a comprehensive summary of the SRs and ACs available in Japan and describe our institutional approach to device selecting using representative cases treated with the combined technique.

Neuroimaging studies prior to endovascular treatment for acute ischemic stroke provide essential information for determining eligibility (treatment triage) and procedural strategies. A fundamental concept of recanalization therapy is the mismatch between the ischemic core (irreversibly damaged tissue) and ischemic penumbra (severely hypoperfused, functionally impaired, at-risk, but not yet infarcted tissue). The goal of recanalization therapy is to recanalize an occluded blood vessel, restore blood flow to penumbral tissue before the ischemic core expands, and save the penumbra tissue. Perfusion imaging allows noninvasive evaluation of the ischemic core and penumbral tissue, although the ischemic penumbra is difficult to discern clinically or based on noncontrast imaging alone. Automated postprocessing software can quickly calculate the location and volume of the ischemic core and penumbra. Optimal thresholds vary depending on the specific perfusion software platform. CT perfusion occasionally overestimates or underestimates ischemic core volume. Discordance among CT perfusion findings, clinical symptoms, and CT angiography findings can provide an additional suggestion for the diagnosis of a stroke mimic.

Balloon-assisted coil embolization is widely used for cerebral aneurysms. Compared to other treatment techniques, such as stent-assisted coiling, flow diverters, and intrasaccular devices, this method offers numerous advantages. Given the availability of multiple balloon catheter products, understanding the characteristics of each product and selecting the appropriate device are essential. Balloon catheters are primarily classified based on the number of lumens and balloon compliance. Devices with single and double lumens differ significantly in terms of the priming procedures, usage methods, and mechanical properties. The compliance type of the balloon determines its suitability for specific aneurysm morphologies. In this article, we present a comprehensive review of the structure, properties, and distinctions among currently available balloon catheters.
