    Objective: To investigate the application value, feasibility, and safety of modified single-port laparoscopic surgery in the treatment of pediatric inguinal hernia. Methods: One hundred and twenty cases of children with indirect inguinal hernia admitted from 2017 to 2022 were enrolled in the Control and Observation groups, with 80 and 40 cases, respectively. They underwent traditional open high ligation of the hernia sac and modified single-port laparoscopic high ligation of the hernia sac, respectively. The operation duration, surgical incision size, intraoperative bleeding, postoperative hospital stay, first ambulation time, and hospitalization expenses were compared between the two groups, as well as the incidence of surgical complications in the two groups. Results: The surgical incision size, intraoperative bleeding, postoperative hospital stay, and first ambulation time of the Observation group were less than those of the Control group. There was no significant difference in operation duration or hospitalization expenses between the two groups. Only two cases in the Observation group showed suture knot reactions after surgery, with no incision infection, inguinal hematoma, iatrogenic cryptorchidism, etc. The overall incidence of complications in the Observation group was lower than that of the Control group. Conclusion: Modified single-port laparoscopic surgery for inguinal hernia in children has the advantages of minimal invasiveness, and enhanced recovery, along with fewer complications and recurrence, hence it is worthy of recommendation in clinical practice.

    方法:一个实时AI辅助软件(神经血管辅助,iMed技术,东京,日本)在9例未破裂动脉瘤患者的线圈栓塞手术中使用。人工智能系统提供了“线圈标记接近”的实时通知,\'导丝运动\',和双平面荧光图像上的“设备条目”。功效,准确度,并使用录像记录评估通知的安全性.
    结果:AI系统在所有情况下都能正常运行。线圈标记接近的平均通知次数,导丝运动,每个程序的装置输入分别为20.0,3.0和18.3.总体准确率和召回率分别为92.7%和97.2%,分别。26个真阳性导丝通知中有5个(19%)导致导丝向其原始位置调整。表明人工智能系统的潜在有效性。无不良事件发生。
    结论:在这项初步研究中,该软件足够准确和安全,表明其潜在的有用性。据我们所知,这是首次报道使用实时AI系统来辅助人类的脑动脉瘤盘绕。有必要进行大规模研究以验证其有效性。实时AI辅助在未来的神经血管内治疗中具有巨大的潜力。
    BACKGROUND: Neuroendovascular procedures require careful and simultaneous attention to multiple devices on multiple screens. Overlooking unintended device movements can result in complications. Advancements in artificial intelligence (AI) have enabled real-time notifications of device movements during procedures. We report our preliminary experience with real-time AI-assisted cerebral aneurysm coiling in humans.
    METHODS: A real-time AI-assistance software (Neuro-Vascular Assist, iMed technologies, Tokyo, Japan) was used during coil embolization procedures in nine patients with an unruptured aneurysm. The AI system provided real-time notifications for \'coil marker approaching\', \'guidewire movement\', and \'device entry\' on biplane fluoroscopic images. The efficacy, accuracy, and safety of the notifications were evaluated using video recordings.
    RESULTS: The AI system functioned properly in all cases. The mean number of notifications for coil marker approaching, guidewire movement, and device entry per procedure was 20.0, 3.0, and 18.3, respectively. The overall precision and recall were 92.7% and 97.2%, respectively. Five of 26 true positive guidewire notifications (19%) resulted in adjustment of the guidewire back toward its original position, indicating the potential effectiveness of the AI system. No adverse events occurred.
    CONCLUSIONS: The software was sufficiently accurate and safe in this preliminary study, suggesting its potential usefulness. To the best of our knowledge, this is the first reported use of a real-time AI system for assisting cerebral aneurysm coiling in humans. Large scale studies are warranted to validate its effectiveness. Real-time AI assistance has significant potential for future neuroendovascular therapy.

    我们报告了一例极为罕见的病例,该病例是在老年男性中进行经桡动脉冠状动脉造影以治疗不稳定型心绞痛的情况下,鹅颈圈套器辅助从主动脉弓取回栓塞的冠状动脉导丝。在这种情况下,使用花瓣圈套器无法从肱动脉或主动脉根部取回栓塞的冠状动脉导丝的近端。从这种情况下的关键结论是,可以在诸如主动脉弓之类的中等宽敞区域中,用鹅颈圈套器从近端成功取回栓塞的冠状动脉导丝。
    We report an extremely rare case of gooseneck snare-assisted retrieval of an embolized coronary guidewire from the aortic arch in an elderly male scheduled for a transradial coronary angiogram for unstable angina. In this case, the proximal end of the embolized coronary guidewire could not be retrieved from the brachial artery nor the roomy aortic root using a flower petal snare. The key takeaway from this case is that an embolized coronary guidewire can be successfully retrieved with a gooseneck snare from its proximal end in a moderately spacious area like the aortic arch.

    UNASSIGNED: Following deployment of the F/B-EVAR endograft, the target vessels (TVs) are cannulated. The bundle wire technique provides a solution to challenging TVs and uses multiple fine atraumatic guidewires that together serve as a stiff guidewire. The technique can be executed in 2 ways using: (1) one 0.018 inch and one 0.014 inch guidewire or (2) three 0.014 inch guidewires. We demonstrate the technique in a case of a complex abdominal aortic aneurysm treated using branched EVAR in which the left renal artery with severe ostial stenosis was catheterized using the bundle wire technique.
    UNASSIGNED: The bundle wire technique offers a technically feasible and economically viable solution for facilitating catheter and bridging stent delivery in anatomically challenging TVs during F/B-EVAR. It is a useful addition to the therapeutic armamentarium available to physicians for accessing demanding TVs.

    BACKGROUND: Neurointerventionalists must pay close attention to multiple devices on multiple screens simultaneously, which can lead to oversights and complications. Artificial intelligence (AI) has potential application in recognizing and monitoring these devices on fluoroscopic imaging.
    METHODS: We report out preliminary experience with a real time AI assistance software, Neuro-Vascular Assist (iMed technologies, Tokyo, Japan), in six patients who underwent carotid artery stenting. This software provides real time assistance during endovascular procedures by tracking wires, guiding catheters, and embolic protection devices. The software provides notification when devices move out of a predefined region of interest or off the screen during the procedure. Efficacy, safety, and accuracy of the software were evaluated.
    RESULTS: The software functioned well without problems and was easily used. Mean number of notifications per procedure was 21.0. The mean numbers of true positives, false positives, and false negatives per procedure were 17.2, 3.8, and 1.2, respectively. Precision and recall were 82% and 94%, respectively. Among the 103 true positive notifications, 24 caused the operator to adjust the inappropriate position of the device (23%), which is approximately four times per procedure. False notifications occurred because of false positive device detection. No adverse events related to the software occurred. No periprocedural complications occurred.
    CONCLUSIONS: Neuro-Vascular Assist, a real time AI assistance software, worked appropriately and may be beneficial in carotid artery stenting procedures. Future large scale studies are warranted to confirm.

    可以将导管分流器插入前房,睫状沟,或parsplana。叉管放置可能具有挑战性。本报告展示了三种导丝辅助沟管插入技术。
    第一种技术使用针通过从管进入部位横穿180度的穿刺术插入,并创建ab-interno巩膜切开术,通过将导丝插入针斜面。第二种技术涉及通过穿刺术将导丝插入眼睛中,并使用微镊子通过巩膜切开术将其取回。第三种技术使用镊子将导丝插入与计划的管进入部位成180°的穿刺术中,并将其对接到已插入沟中的针斜面中。这些技术中的每一种都提供了将管插入沟中的可靠且可重复的方式。
    导丝辅助管进入提供了一个有前途的解决方案,在困难的沟管放置没有大量额外的成本。
    UNASSIGNED: Tube shunts can be inserted into the anterior chamber, ciliary sulcus, or pars plana. Sulcus tube placement can be challenging. This report demonstrates three techniques for guidewire-assisted sulcus tube insertion.
    UNASSIGNED: The first technique uses a needle inserted through a paracentesis 180-degrees across from the tube entry site and creates an ab-interno sclerotomy through which the guidewire is inserted by docking it into the needle bevel. The second technique involves inserting the guidewire into the eye via a paracentesis and using microforceps to retrieve it through a sclerotomy. The third technique uses forceps to insert the guidewire into a paracentesis 180° across from the planned tube entry site and dock it into a needle bevel that has been inserted into the sulcus. Each of these techniques provides a reliable and reproducible way to insert a tube into the sulcus.
    UNASSIGNED: Guidewire-assisted tube entry offers a promising solution in cases of difficult sulcus tube placement without substantial additional cost.

    植入工具的表面形貌表明仍在发现降解的界面接触;然而,微小的镁线的光泽质地对于可吸收医疗设备很重要。本文研究了使用具有旋转输入参数的旋转磁场辅助系统通过磁性磨料抛光方法对表面质量的影响,研磨介质,磁极,通量密度,振动,和振幅可以显着增强样品的凹凸。此外,血流模拟用于分析血管内的流动,同时保持导丝的表面粗糙度条件。对结果进行了比较和讨论。采用磁场模拟来研究抛光区的磁场强度。扫描电子显微镜(SEM)为识别镁线工件前后的差异提供了视觉帮助。实验结果表明,0.50mm的线径主要实现了从0.22μm到0.05μm的初始粗糙度的表面形态。结果证实血液在循环系统中的分布相对稳定。因此,这项研究为超细镁线的精密抛光建立了一个至关重要的基准,这对于它们用作高精度可生物降解的医疗设备至关重要。
    The surface topography of implant tools has indicated an interfacial contact in degradation still being discovered; however, the glossy texture of a tiny magnesium wire is important for absorbable medical devices. This paper investigated the alterations of surface quality by a magnetic abrasive polishing method using a rotational magnetic field-assisted system with input parameters of revolution, abrasive media, magnetic pole, flux density, vibration, and amplitude that could noticeably enhance asperities along a sample. Furthermore, the blood flow simulation is used to analyze flow within blood vessels while maintaining the surface roughness conditions of the guide wire. The results are compared and discussed. Magnetic field simulation is employed to investigate the magnetic field strength in the polishing zone. Scanning Electron Microscopy (SEM) provides visual aids for recognizing the differences between pre-and post-workpieces of magnesium wire. The experimental results reveal that a wire diameter of 0.50 mm predominantly achieves surface morphology from the initial roughness of 0.22 μm to 0.05 μm. The results corroborate that the distribution of blood in the circulatory system was relatively stable. Hence, this study establishes a crucial benchmark for the precision polishing of ultra-thin magnesium wires, which is vital for their use as high-precision biodegradable medical devices.
