This situation raises questions as to whether the phenotype of moyamoya disease changes with age. Objective: We performed self-precontrol and postcontrol observation monitoring until adulthood on abnormal collateral vessels (ACVs) with the potential risk of bleeding to evaluate the chance of further hemorrhage. Methods: Fifteen pediatric patients with >10 years angiography-based follow-up were analyzed. The Matsushima grades were divided into 2 groups (good group, representing Matsushima stage A; and mild group, representing Matsushima stages B and C) to investigate the relationship between Matsushima grades and ACVs derived from vessels likely to cause intracranial hemorrhage. Results: Four patients (26.7%) had infarction type and 11 (73.3%) patients had transient ischemic attack type. No patient experienced late-onset cerebral hemorrhagic events. One patient experienced recurrent ischemic stroke 6 months after the second surgery and recovered completely after the third surgery. The angiography-based follow-up was conducted at least 10 years after the encephaloduroarteriosynangiosis (EDAS). The good Matsushima group showed a significant positive correlation with the reduction of the anterior choroidal artery (odds ratio, 56.00; P = 0.003), whereas the posterior communicating artery showed no significant decrease before and after the EDAS procedure (odds ratio, 2.00; P = 1.00). Conclusions: The EDAS procedure can effectively attenuate the dilation and ACVs of the anterior choroidal artery, which may reduce the incidence of further hemorrhage in adulthood.

    查看更多>>摘要：? 2021Objective: Anterior cervical discectomy and fusion (ACDF) has been considered the standard treatment for degenerative cervical disc disease; however, recent trials have shown comparable outcomes with cervical disc arthroplasty (CDA). This study aimed to observe disparities in treatment paradigms of single-level cervical disc diseases and compare inpatient outcomes between procedures. Methods: A retrospective cohort of patients treated for single-level cervical disc herniation or degeneration without myelopathy was queried from the Nationwide Inpatient Sample spanning 2012–2015. Multivariate logistic regression was performed to assess the effects of demographics, temporality of admission, and hospital characteristics on odds of receiving CDA versus ACDF. Propensity-score matching was performed to compare cost, length of stay (LOS), non-home discharge, and inpatient complications. Results: In total, 1028 CDAs and 44,374 ACDFs were performed for single-level cervical disc disease during 2012–2015. Matched comparison showed that while non-home discharges were not different between CDA and ACDF (P = 0.248), patients who received CDA had a 0.19-day shorter LOS (P < 0.001) and $4694 greater total cost (P < 0.001). There were no statistically significant differences in inpatient complication rates. Multivariate analysis showed that patients in the 26th–50th percentile, 51st–75th percentile, and 76th–100th percentile of median household income had greater odds of CDA compared with patients in the 0–25th percentile (odds ratio [OR] 1.35, P = 0.003; OR 1.31, P = 0.013; OR 1.34, P = 0.011, respectively). Patients with private insurance had greater odds of receiving CDA compared with patients on Medicare (OR 1.91, P < 0.001). Conclusions: CDA was associated with shorter LOS but greater costs compared with ACDF. Patients with greater median income and private insurance were more likely to receive CDA.

    查看更多>>摘要：? 2022 Elsevier Inc.Objective: For the majority of patients, the Internet constitutes the first source of health information influencing their medical decision-making. We aimed to assess the quality of the online videos regarding anterior lumbar interbody fusion (ALIF). Methods: YouTube database was searched using 3 different phrases: “anterior lumbar interbody fusion”, “ALIF”, and “ALIF surgery”. The first 50 videos for each phrase were selected. Video content was evaluated by 3 independent researchers using the DISCERN instrument. Qualitative data, quantitative data, and the source of upload were analyzed. Results: A total of 24 videos were included. The mean DISCERN score was 38.21, indicating the poor quality of ALIF videos on YouTube. Video duration was positively correlated with DISCERN score (r = 0.71, P < 0.001) but not with the video power index (VPI). A negative correlation between time since upload and DISCERN score (r = –0.8 P < 0.001) was found. Furthermore, videos containing surgical complications, risk factors, and postoperative prognosis had a significantly higher DISCERN score. Neither DISCERN score nor a VPI correlated with the presence of intraoperative recordings. Videos including the explanation of the spine anatomy had a significantly higher number of likes (P = 0.018). Conclusions: Despite the increasing educational value of ALIF videos over time, the overall quality of YouTube videos on ALIF remains poor. However, the majority of videos can be recommended to the patient as an informative source of basic knowledge on the surgical details of the ALIF procedure. Longer video duration increases its quality without simultaneous negative influence on its popularity.

    Infratemporal Fossa Vascular Anatomy Pertinent to Percutaneous Access to the Foramen Ovale for Treatment of Trigeminal Neuralgia: A Comparison of Cadaveric Dissection and Computed Tomography Analysis

    Lawrence J.D.Cheyuo C.Marsh R.A.
    7页
    查看更多>>摘要：? 2022Background: Trigeminal neuralgia may be treated via percutaneous access to the foramen ovale (FO). Vascular complications associated with the needle trajectory can result in serious morbidity and mortality. This study aimed to correlate the vascular relationships of the FO at the skull base via cadaveric dissections and computed tomography (CT). Methods: Two fresh cadaver heads were injected with red and blue latex to delineate arteries and veins. Neck and infratemporal fossa dissections were carried out to delineate the vascular relationships of the FO. High-resolution head CT images of adult patients undergoing neurosurgical evaluations or procedures were analyzed for distances and sizes of skull base foramina in the infratemporal fossa. Results: Three infratemporal fossa dissections (2 cadaveric specimens) were performed. Mean distance of FO to internal carotid artery was 2.4 ± 0.12 cm, and mean distance of FO to middle meningeal artery was 0.8 ± 0.16 cm. Head CT images of 52 patients (104 sides) with 1-mm axial slice thickness were analyzed. Area of the FO was 31.1 ± 9.6 mm2. Distance of FO to internal carotid artery was 1.70 ± 0.31 cm, and distance of FO to middle meningeal artery was 0.73 ± 0.61 cm. Conclusions: Cadaveric delineation of vascular structures in the infratemporal fossa correlates with head CT imaging and may be used to accurately plan percutaneous access to the FO. Inadvertent puncture of the extracranial internal carotid artery is nearly impossible with good technique. The most likely source of percutaneous vascular injury is the middle meningeal artery and distal branches of the maxillary artery.

    查看更多>>摘要：? 2022 Elsevier Inc.Objective: Surgical resection of intracranial hemangioblastoma poses technical challenges that may be difficult to impart to trainees. Here, we introduce knowledge of tool-tissue forces in Newton (N), observed during hemangioblastoma surgery. Methods: Seven surgeons (2 groups: trainees and mentor), with mentor (n = 1) and trainees (n = 6, PGY 1-6 including clinical fellowship), participated in 6 intracranial hemangioblastoma surgeries. Using sensorized bipolar forceps, we evaluated tool-tissue force profiles of 5 predetermined surgical tasks: 1) dissection, 2) coagulation, 3) retracting, 4) pulling, and 5) manipulating. Force profile for each trial included force duration, average, maximum, minimum, range, standard deviation (SD), and correlation coefficient. Force errors including unsuccessful trial bleeding or incomplete were compared between surgeons and with successful trials. Results: Force data from 718 trials were collected. The mean (standard deviation) of force used in all surgical tasks and across all surgical levels was 0.20 ± 0.17 N. The forces exerted by trainee surgeons were significantly lower than those of the mentor (0.15 vs. 0.24; P < 0.0001). A total of 18 (4.5%) trials were unsuccessful, 4 of them being unsuccessful trial?bleeding and the rest, unsuccessful trial–incomplete. The force in unsuccessful trial–bleeding was higher than successful trials (0.3 [0.09] vs. 0.17 [0.11]; P = 0.0401). Toward the end of surgery, higher force was observed (0.17 vs. 0.20; P < 0.0001). Conclusions: The quantification of tool-tissue forces during hemangioblastoma surgery with feedback to the surgeon, could well enhance surgical training and allow avoidance of bleeding associated with high force error.

    查看更多>>摘要：? 2022 Elsevier Inc.Background: Distal medium vessel occlusions (DMVOs) are increasingly recognized as a next target for endovascular thrombectomy (EVT). Our objective was to investigate safety and clinical outcomes of EVT for DMVO of the middle cerebral artery (MCA). Methods: We analyzed data of the Lille Reperfusion Registry from January 2017 to September 2020. Patients with a primary or secondary DMVO of the MCA seen on pretreatment angiogram were included. Only patients with a eTICI score 2b50–2b67 on initial angiogram were considered. Baseline characteristics, angiographic clinical, and safety outcomes were compared between patients treated with EVT or standard medical treatment (no-EVT). Results: Of the 171 patients included, 96 received EVT (46.9% male, 68.7 ± 15.8 years) and 75 received standard medical treatment (44% male, 73.9 ± 13.1 years). EVT patients had a better improvement of the NIHSS score at discharge (adjusted mean difference: 3.71; 95% CI: 1.18–6.24). In the distal M2 occlusions subgroup, EVT was significantly associated with a higher rate of early neurologic improvement (adjusted OR: 3.62 95% CI: 1.31–10.03), NIHSS improvement at discharge (adjusted mean difference: 5.23; 95% CI: 2.18–8.29), and improved modified Rankin Scale score at 3 months (adjusted common OR for 1 point improvement: 3.06; 95% CI: 1.30 to 7.23). Symptomatic intracranial hemorrhage occurred in 3.1% in the EVT group and in 9.5% in the no-EVT group. Conclusions: EVT for DMVO of the MCA appears to be safe and may lead to improved clinical outcomes. This effect was especially pronounced in patients with distal M2 occlusions, warranting randomized trials to validate this result.

    查看更多>>摘要：? 2021 Elsevier Inc.Background: Despite the fact that bevacizumab (Bev) has been approved to treat recurrent glioblastoma, patients have failed to demonstrate a significant overall survival (OS) advantage. In recent years, the advent of more Bev combination regimens seems to bring new hope for patients; nevertheless, there is still a lack of intuitive comparison among these therapies. Objective: To explore the efficacy and safety of various Bev combination regimens in patients with recurrent glioblastoma and to further explore the differences in the efficacy of each treatment in randomized controlled trials (RCTs) and nonrandomized controlled trials (non-RCTs). Methods: We comprehensively searched the PubMed, Cochrane Library, and OVID databases for relevant RCTs and non-RCTs of Bev in combined regimens for recurrent glioblastoma. The Cochrane quality assessment method was used to assess the quality of RCTs, and the Newcastle-Ottawa scale was used to assess the quality of non-RCTs. Excel software was used to extract data from the literature, and a network meta-analysis was performed using RevMan 5.3 and Stata 16 statistical software. Results: In patients with recurrent glioblastoma, the 6-month OS of patients receiving bevacizumab combination therapy was ranked from high to low as follows: Bev + rindopepimut, Bev + lomustine (CCNU), CCNU, tumor treating fields + Bev, Bev, Bev + irinotecan (Iri), Bev + temozolomide (TMZ), Bev + vorinostat, Bev + onartuzumab, Bev + dasatinib, Bev + carboplatin, Bev + trebananib, Bev + VB-111, TMZ, PCV, VB-111, and carboplatin. The 6-month progression-free survival from high to low was ranked as follows: Bev + CCNU, Bev + rindopepimut, Bev + dasatinib, Bev + vorinostat, Bev, Bev + Iri, Bev + TMZ, CCNU, Bev + carboplatin, TMZ, Bev + VB-111, PCV, Bev + trebananib, carboplatin, and VB-111. We compared the total incidence of serious adverse events (≥3) and found that Bev + vorinostat and Bev + trebananib were safer than Bev, while other regimens were not as safe as Bev. A descriptive analysis showed that Bev + rindopepimut also appeared to be safer than Bev. In subgroup analysis, among RCTs, Bev + CCNU therapy had the highest 6-month OS and 6-month progression-free survival. Among non-RCTs, Bev + Iri therapy showed the highest 6-month OS and good 6-month progression-free survival. Conclusions: Both Bev + CCNU and Bev + rindopepimut could be considered as effective therapies for treating the recurrent glioblastoma according to the network meta-analysis results. Among them, Bev + rindopepimut therapy seems to be safer and more effective. Moreover, we found that Bev + Iri also appeared to be an effective therapy in a retrospective study.

    Beach Breaking Waves and Related Cervical Spine Injuries: A Level One Trauma Center Experience and Systematic Review

    Griepp D.W.De la Garza Ramos R.Lee J.Miller A....
    10页
    查看更多>>摘要：? 2022 Elsevier Inc.Objective: To analyze cervical spine injuries resulting from recreational activity in shallow ocean water amid high-energy breaking waves. Methods: Single-center 10-year review of patients who sustained cervical injuries at the beach in Long Island, New York, USA. A systematic review following the PRISMA guidelines was also performed. Results: Nineteen patients (age 17–79 years) sustained cervical injury from high-energy breaking waves while in shallow beach water. Six patients dived into a wave; 6 patients were struck by a large wave while standing upright; and 7 tumbled in the waves while engaged in nonspecified recreational activity. All 7 patients with subaxial cervical AO Spine Injury Score (AO-SIS) >10 had cervical spine injury with cord signal change and required operative management. Diving mechanism, AO-SIS >10, and cord signal change all predicted significant disability or death at 12 months (P < 0.01). The present study and 7 additional studies reporting on 534 patients (mean age, 45.4 years) were analyzed. Within the reported literature, most patients (94.2%) sustained a spinal cord injury. On long-term follow-up, an estimated 64.8% of patients had permanent neurologic injury and 12.5% had permanent quadriplegia. Conclusions: We offer the first description of cervical injuries sustained in water-related recreational activity using the AO-SIS. The morphology of injuries varied significantly and seemed to depend on body position and wave kinetic energy. Patients presenting with cervical injury in this setting and yielding AO-SIS >10 are likely to have poor functional recovery.

    查看更多>>摘要：? 2022 Elsevier Inc.Background: Internal bands of the basilar artery (BA) have been rarely studied. Because bands could have obvious consequences in patient diagnosis and care, the present multiinstitutional cadaveric study was performed. Methods: The intraluminal bands of BAs were studied in 80 cadaveric specimens derived from India (Group 1) and the United States (Group 2). Their orientation within the vessel was recorded. Measurements included the length of the BA, diameter of the BA, intraluminal band length and thickness, and distance of the band to the vertebrobasilar junction. Selected bands were submitted for histologic analysis. Results: In Group 1, an intraluminal band (all vertically oriented) was identified in 16.6%. The mean length and thickness of the bands were 2.04 mm and 1.33 mm, respectively. These bands were located at a mean distance of 1.74 mm superior to the vertebrobasilar junction. In Group 2, an intraluminal band was identified in 6%. One band was vertically positioned, and 2 were horizontally positioned. The mean length and thickness of the bands were 2.5 mm and 0.9 mm, respectively. These latter bands were located at a mean distance of 2.23 mm superior to the vertebrobasilar junction. Histologically, the bands were essentially extensions of the tunica media and interna of the artery. Conclusions: To our knowledge, this study is the first multiethnic study of the prevalence and morphometry of the BA bands. A better understanding of these bands may help reveal their relationship to thrombus and aneurysmal formation and their impact on endovascular procedures.

    查看更多>>摘要：? 2022 Elsevier Inc.Objective: Surgery for cervical spondylotic myelopathy (CSM) may use anterior or posterior approaches. Our objective was to compare baseline differences and validated postoperative patient-reported outcome measures between anterior and posterior approaches. Methods: The NeuroPoint Quality Outcomes Database was queried retrospectively to identify patients with symptomatic CSM treated at 14 high-volume sites. Demographic, comorbidity, socioeconomic, and outcome measures were compared between treatment groups at baseline and 3 and 12 months postoperatively. Results: Of the 1151 patients with CSM in the cervical registry, 791 (68.7%) underwent anterior surgery and 360 (31.3%) underwent posterior surgery. Significant baseline differences were observed in age, comorbidities, myelopathy severity, unemployment, and length of hospital stay. After adjusting for these differences, anterior surgery patients had significantly lower Neck Disability Index score (NDI) and a higher proportion reaching a minimal clinically important difference (MCID) in NDI (P = 0.005 at 3 months; P = 0.003 at 12 months). Although modified Japanese Orthopaedic Association scores were lower in anterior surgery patients at 3 and 12 months (P < 0.001 and P = 0.022, respectively), no differences were seen in MCID or change from baseline. Greater EuroQol-5D improvement at 3 months after anterior versus posterior surgery (P = 0.024) was not sustained at 12 months and was insignificant on multivariate analysis. Conclusions: In the largest analysis to date of CSM surgery data, significant baseline differences existed for patients undergoing anterior versus posterior surgery for CSM. After adjusting for these differences, patients undergoing anterior surgery were more likely to achieve clinically significant improvement in NDI at short- and long-term follow-up.
