Readability of cerebrovascular diseases online educational material from major cerebrovascular organizations.

INTRODUCTION: The internet is an essential resource for patients and their loved ones to understand their medical conditions, and professional medical organizations have taken great strides to develop educational material targeting patients. The average American reads at a seventh to eighth grade reading level, hence it is important to understand the readability of this medical information to ensure patients comprehend what is being presented. METHODS: In January 2023, online patient education material was downloaded from major cerebrovascular healthcare organizations and assessed using eight assessments, including Bormuth Cloze Mean, Bormuth Grade Placement, Coleman-Liau (grade levels), Coleman-Liau (predictive cloze scores), Flesch Reading Ease (FRE), and Fry. RESULTS: A total of 32 files were extracted from six organizations and analyzed across 15 readability measures. None of the organizations met the federal government guidelines for grade-level readability. This held constant across all measured tests. Two organizations had above a postgraduate level. The FRE graphs do not identify any organizations with material below a ninth grade reading level, while the American Association of Neurological Surgeons (AANS) and the Society of Interventional Radiology (SIR) have a postgraduate readability level. The Fry graphs show similar results, with AANS/CNS Cerebrovascular Section, Society of NeuroInterventional Surgery (SNIS), SIR, and AANS having college-level readability. The lowest readability across all measures is only at an early seventh grade reading level. CONCLUSIONS: Current health literacy content for cerebrovascular patients is far above the recommended readability level. We provide straightforward suggestions for how major professional organizations should improve their informational material on cerebrovascular diseases to improve patient understanding.

Utilization and reimbursement of diagnostic cerebral angiograms: A Medicare trends analysis from 2013 to 2020.

INTRODUCTION: Increasing life expectancy has caused growing concern about maintaining viable neurointerventional practices due to altered Medicare payment structures. This study analyzes the financial trends of three common diagnostic tests for cerebrovascular disease: cerebral digital subtraction angiography (DSA), computed tomography angiography (CTA), and magnetic resonance angiography (MRA). METHODS: Medicare Part B National Summary Data files from 2013 to 2020 were queried by Current Procedural Terminology (CPT) codes for DSA (36221-36228), CTA (70496, 70498), and MRA (70544-70547, 70549). Inflation-adjusted charges and reimbursement were calculated using the U.S. City Average Consumer Price Index for Medical Services. Regression analysis was performed on charges, reimbursement, and volume. RESULTS: A total of 1,519,245 diagnostic procedures were conducted between 2013 and 2020 (782,370 angiograms, 246,603 CTAs, and 490,272 MRAs). A total of $41.005 million was reimbursed by Medicare in 2020 for these diagnostic procedures. The annual percent change in volume for all procedures was -2.90%. From 2013 to 2020, inflation-adjusted: Medicare total physician reimbursement decreased for cerebral angiograms (-4.12%, p = 0.007), CTAs (-2.77%, p = 0.458), and MRAs (-9.06%, p < 0.001). Procedural volume billed to Medicare decreased for cerebral angiograms (-4.63%, p = 0.007) and MRAs (-2.94%, p = 0.0.81) and increased for CTAs (+3.15%, p = 0.004). The greatest increase in Medicare reimbursement (+66.75%) came from CPT code 36224, "place catheter carotid artery", and the greatest decrease in Medicare reimbursement (-8.66%) came from CPT code 36226, "place catheter vertebral artery." CONCLUSIONS: This study provides an analysis of Medicare reimbursement trends for routine cerebrovascular angiogram techniques. The findings highlight a decline in Medicare reimbursements for neurointerventionalists.

Usefulness and Accuracy of Artificial Intelligence Chatbot Responses to Patient Questions for Neurosurgical Procedures.

BACKGROUND AND OBJECTIVES: The Internet has become a primary source of health information, leading patients to seek answers online before consulting health care providers. This study aims to evaluate the implementation of Chat Generative Pre-Trained Transformer (ChatGPT) in neurosurgery by assessing the accuracy and helpfulness of artificial intelligence (AI)-generated responses to common postsurgical questions. METHODS: A list of 60 commonly asked questions regarding neurosurgical procedures was developed. ChatGPT-3.0, ChatGPT-3.5, and ChatGPT-4.0 responses to these questions were recorded and graded by numerous practitioners for accuracy and helpfulness. The understandability and actionability of the answers were assessed using the Patient Education Materials Assessment Tool. Readability analysis was conducted using established scales. RESULTS: A total of 1080 responses were evaluated, equally divided among ChatGPT-3.0, 3.5, and 4.0, each contributing 360 responses. The mean helpfulness score across the 3 subsections was 3.511 ± 0.647 while the accuracy score was 4.165 ± 0.567. The Patient Education Materials Assessment Tool analysis revealed that the AI-generated responses had higher actionability scores than understandability. This indicates that the answers provided practical guidance and recommendations that patients could apply effectively. On the other hand, the mean Flesch Reading Ease score was 33.5, suggesting that the readability level of the responses was relatively complex. The Raygor Readability Estimate scores ranged within the graduate level, with an average score of the 15th grade. CONCLUSION: The artificial intelligence chatbot's responses, although factually accurate, were not rated highly beneficial, with only marginal differences in perceived helpfulness and accuracy between ChatGPT-3.0 and ChatGPT-3.5 versions. Despite this, the responses from ChatGPT-4.0 showed a notable improvement in understandability, indicating enhanced readability over earlier versions.

Patient and Caregiver Perception of Adenoidectomies: A Non-Real-World Social Media Analysis.

Objective: To survey the social media outlets Twitter and Instagram for public posts related to adenoidectomy surgery. This study aims to investigate the attitudes and perceptions of patients and caregivers on social media, through thematic content-analysis of social media posts regarding adenoidectomy. Study Design: Non-real world qualitative study. Setting: Twitter and Instagram social media platforms. Methods: Public posts uploaded between February, 2021 and February, 2023 using the hashtags "#adenoidectomy," and "#adenoidectomyrecovery" were searched. Posts were excluded if they were unrelated to adenoidectomy or were in a non-English language. Relevant posts were stratified demographically as patient or caregiver and pre- or postoperative, and categorized into relevant themes for analysis. Outcomes were measured as the total number of posts. Results: A total of 394 relevant posts were analyzed. A significance threshold of P < 0.05 was used. Patients posted significantly more posts regarding procedure pain (P = 0.002) and concern for appearance (P = 0.048) compared to caregivers. Caregivers posted significantly (P < 0.001) more posts regarding condition awareness and were significantly (P < 0.001) more likely to spread positivity in their posts compared to patients themselves. Posts made by female caregivers were more likely to reference fear, while those made by male caregivers were more likely to provide education (P = 0.002). Conclusion: Patients may worry about appearance and mental health while caregivers are more likely to spread information and positivity. Male and female caregivers may also use social media differently. A better understanding of patient and caregiver concerns may optimize physician interaction and involvement.

Cerebral Cavernous Malformations Patient Perception Analysis via Social Media.

BACKGROUND: The rise of social media has allowed for individuals and patients to connect with each other and influence patient behavior. This study aimed to improve our understanding of the patients' experience with cerebral cavernous malformations (CCM) via social media. METHODS: Instagram and Twitter were searched using terms of ("cavernoma," "cavernous malformations," "cavernous angioma," or "cav mal"). Public Instagram posts tagged with "#cavernoma" and "@cavernoma" identified 327 posts that directly included a patient's own experience. Twitter posts that included "#cavernoma" and "@cavernoma" were searched, yielding 75 after eliminating those that did not pertain to the patient's own experience. The posts and tweets were coded for relevant themes related to their experience with the disease. RESULTS: Overall, more patients are using Instagram (n = 327) over Twitter (n = 84) to share their personal experience with CCM with a trend for male patients to use Twitter more compared to females with a female predominance in Instagram. A total of 277 of 327 (84.7%) Instagram posts and 67 of 84 (89.3%) Twitter posts were made after the patient's surgery. The most common theme on Instagram was focused on the postoperative rehabilitation process and mobility support (52.0 and 24.5%, respectively). Other common themes present on Twitter and Instagram were recounting symptoms and complications and life satisfaction (26.0 and 24.2%, respectively). Cavernoma patients prior to surgery were more likely to discuss on Instagram their symptoms (p = 0.001), fear of bleeding (p < 0.001), and mental health (p = 0.014). Postoperatively, cavernoma patients were more likely to discuss disability than they were preoperatively (p = 0.001). CONCLUSION: Social media platforms offer a communication tool for patients with CCM patients to share their experience with other patients and the general public and portrays their personal experience with CCM. These platforms allow for physicians to better understand the patient experience following cavernoma surgery.

Art and Neurosurgery: The Importance of Medical Illustration.

Art in neurosurgery has been a critical part of the discipline for centuries. Numerous cultures, such as ancient India, China, and Egypt, and more contemporary scientists, such as Leonardo da Vinci, Max Brödel, and Norman Dott, have significantly contributed to medical illustration. Today, advancements in three-dimensional technology have allowed for the creation of detailed neuroanatomy models for surgical planning and education. Medical illustrations are also used for research and outcome documentation as they help visualize anatomy and surgical procedures. Its use in education, surgical planning, and navigation remains integral to the advancement of neurosurgery. This review demonstrates the invaluable contribution of art in neurosurgery and how it has enabled continuous progress in the field.

Management of Atypical Teratoid/Rhabdoid Tumors in the Pediatric Population: A Systematic Review and Meta-Analysis.

BACKGROUND: Atypical teratoid/rhabdoid tumors are rare and aggressive tumors that mainly affect children <3 years of age. Despite aggressive treatment, the overall survival rate for pediatric atypical teratoid/rhabdoid tumors remains poor. Due to their rarity, little is known regarding prognostic factors, and there is no official standard of treatment. METHODS: A comprehensive database search was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Search terms included "atypical teratoid rhabdoid tumor" and "atypical (teratoid OR rhabdoid) tumor." Variables of interest included, but were not limited to, age, sex, tumor location, treatment modality, extent of resection, and overall survival. RESULTS: The study included 294 articles and 936 patients. The median age of patients was 22 months. There was a significant difference in survival among patients receiving surgery compared with patients receiving nonoperative treatment (50.3 months vs. 28 months; P < 0.005). Extent of resection did not significantly improve survival (P = 0.832 for gross total resection, P = 0.650 for partial resection). Combination therapy with surgical resection, radiotherapy, and chemotherapy demonstrated the largest median overall survival (54.9 months) and significantly improved survival on multivariate analysis (hazard ratio, 0.48; 95% confidence interval, 0.23-0.97; P = 0.042). CONCLUSIONS: The results of this study indicate that while surgery is a crucial treatment modality for pediatric atypical teratoid/rhabdoid tumors, the effect of extent of resection is unclear. Multimodal therapy including surgery, radiotherapy, and chemotherapy is effective in improving overall survival. Future studies should focus on using larger datasets to efficiently account for confounding factors and biases.

Post-operative weight loss in venous sinus stenting patients: A multi-center review, systematic review, and meta-analysis.

INTRODUCTION: Idiopathic intracranial hypertension (IIH) can result in headaches, pulsatile tinnitus, papilledema, and other neurological symptoms. Weight loss can alleviate some symptoms of IIH. This study aims to investigate the effect of venous sinus stenting on post-operative weight and body mass index (BMI) changes among IIH patients. The secondary objective is to investigate the relationship between post-operative weight changes and papilledema resolution. METHODS: Patients with papilledema undergoing venous sinus stenting for IIH were retrospectively reviewed from two comprehensive North American cerebrovascular centers. Patient demographics, surgical course, post-operative outcomes, and weight were analyzed. A systematic review and meta-analysis of post-operative weight in stented IIH patients was conducted. RESULTS: Twenty-eight patients with a diagnosis of IIH and papilledema who underwent venous sinus stenting were identified across two institutions. Patients had a mean pre-operative weight of 103.2 kg, which decreased to 101.5 kg at 3-month follow up (p = 0.0757). Patients at 6-month follow-up saw a weight decrease to 97.4 kg (p = 0.0066). Patients who saw papilledema resolution saw a mean greater decrease in weight (-4.5%) at 6-month follow up than those whose papilledema did not resolve (-1.7%), although this was insignificant (p = 0.1091). A total of 41 patients were included in the meta-analysis. Patients had an average of 1.1 increase in BMI at 3-month follow up. CONCLUSIONS: This study shows that venous sinus stenting leads to modest weight reduction in IIH patients, and those with resolved papilledema experience slightly greater weight loss. Further research is necessary to determine the clinical significance of these findings.

Intraoperative angiography in neurosurgery: temporal trend, access site, and operative indication considerations from a 6-year institutional experience.

BACKGROUND: Historically, the transfemoral approach (TFA) has been the most common access site for cerebral intraoperative angiography (IOA). However, in line with trends in cardiac interventional vascular access preferences, the transradial approach (TRA) and transulnar approach (TUA) have been gaining popularity owing to favorable safety and patient satisfaction outcomes. OBJECTIVE: To compare the efficacy and safety of TRA/TUA and TFA for cerebral and spinal IOA at an institutional level over a 6-year period. METHODS: Between July 2016 and December 2022, 317 angiograms were included in our analysis, comprising 60 TRA, 10 TUA, 243 TFA, and 4 transpopliteal approach cases. Fluoroscopy time, contrast dose, reference air kerma, and dose-area products per target vessel catheterized were primary endpoints. Multivariate regression analyses were conducted to evaluate predictors of elevated contrast dose and radiation exposure and to assess time trends in access site selection. RESULTS: Contrast dose and radiation exposure metrics per vessel catheterized were not significantly different between access site groups when controlling for patient position, operative region, 3D rotational angiography use, and different operators. Access site was not a significant independent predictor of elevated radiation exposure or contrast dose. There was a significant relationship between case number and operative indication over the study period (P<0.001), with a decrease in the proportion of cases for aneurysm treatment offset by increases in total cases for the management of arteriovenous malformation, AVF, and moyamoya disease. CONCLUSIONS: TRA and TUA are safe and effective access site options for neurointerventional procedures that are increasingly used for IOA.

Patient perception of spinal cord injury through social media: An analysis of 703 Instagram and 117 Twitter posts.

Introduction: Social media has developed exponentially over the last decade as a means for individuals and patients to connect to others and has provided a unique opportunity for physicians to provide broader information to the general public to attempt to positively modify health behavior. The purpose of this study was to assess the patient's perception of spinal cord injury (SCI) on social media. Methods: Instagram and Twitter social media platforms were analyzed to determine posts written by patients with SCI. The initial search for Instagram posts tagged with "#spinalcordinjury" yielded over 270,000 posts in April 2021. Posts pertaining to the patient's experience were retrospectively collected from January 2020 to April 2021. Twitter posts that included "#spinalcordinjury," "@spinalcordinjury," and "spinal cord injury" were retrospectively collected in April 2021. One hundred seventeen tweets were found that were directly from a patient with SCI. Themes associated with patients' experiences living with SCI were coded. Results: The most common theme on Instagram was spreading positivity and on Twitter was the appearance of the wheelchair (75.8% and 37.3%, respectively). Other common themes on Instagram were the appearance of a wheelchair (71.8%), recovery or rehabilitation (29.9%), and life satisfaction (29.0%). Prevalent themes on Twitter included spreading positivity (23.2%) and recovery or rehabilitation (21.3%). Conclusion: The prevalence of themes of positivity and awareness may indicate the utilization of social media as a support mechanism for patients living with SCI. Identification of prevalent themes is important for the holistic treatment of SCI survivors.

Patient sentiment regarding stroke: Analysis of 2,992 social media posts.

INTRODUCTION: Social media reflects personalized sentiment toward disease and increasingly impacts perceptions of treatment options. This study aims to assess patients experience with and perception of stroke through an analysis of social media posts. METHODS: A variety of terms ("stroke", "stroke survivor", "stroke rehab", "stroke recovery") were used to search for possible qualified posts on Twitter and Instagram. Twitter posts containing "#stroke" and "@stroke" were identified, yielding 2,506 Twitter posts relating to the patient's own experience. Four hundred sixty-eight public Instagram posts marked under "#stroke" and "@stroke," including direct references to the patient's own experience, were analyzed. First vs. recurrent stroke was identified when possible. The posts were coded for themes relating to patient experience with the disease. RESULTS: The most common Twitter theme was raising stroke awareness (23.4 %), while spreading positivity was the most common Instagram theme (66.7 %). Most Twitter posts (93.9 %) were from patients experiencing their first stroke, with only 6.1 % of the posts being about recurrent strokes. Women created the majority of Instagram (75.7 %) and Twitter (77.3 %) posts. Men were more likely to discuss mobility/functional outcomes (p = 0.001) and survival/death (p = 0.014), while women were more likely to recount symptoms (p = 0.014), depression (p = 0.002), fear (p<0.001), and mental health (p = 0.006). CONCLUSION: Stroke patients most often describe their quality of life and discuss raising awareness via social media. Men and women differ in the most commonly shared aspects of their stroke experience. Gauging social media sentiment may guide physicians toward better counseling and psychosocial management of stroke patients.

Cross-Sectional Analysis of Neurosurgical Residency Websites During the Virtual Interview Cycle.

BACKGROUND: The loss of in-person interviews during the COVID-19 pandemic warrants an investigation into what information is provided to applicants through neurosurgery residency program websites (NRPWs). This study examines NRPWs across the United States and Canada to determine what details are provided to applicants through their respective websites. METHODS: Accreditation Council for Graduate Medical Education accredited neurologic surgery residency programs were identified through the American Association of Neurological Surgeons (AANS) website. NRPWs were searched for 48 criteria, including program overview, application requirements, and curriculum information. Small programs were defined as 1-2 residents per class, while large programs were classified as those with 3-4 residents per year. Content differences were analyzed between the top 20 and remaining programs per the Doximity Residency Navigator Rankings. RESULTS: The most prevalent information among 122 NRPWs was the neurosurgery residency overview (95%), names of faculty members (95%), and names of current residents (94%). Top-20 NRPWs were more likely to include post PGY-7 fellowships (90% vs. 61% P = 0.0108), operating room virtual reality experience (35% vs. 12% P = 0.0160), and faculty research (90% vs. 62% P = 0.0182) than the remainder of the programs. CONCLUSIONS: This study investigates NRPW content after the COVID-19 pandemic. We report broad variability in content provided by various neurosurgical training programs. Higher-ranked neurosurgery programs are more likely to include fellowship information, operating room virtual reality experience, and faculty research than lower-ranked programs.

Feasibility and safety of transradial intraoperative angiography for neurosurgery: An institutional experience.

BACKGROUND: Transradial approach for neuroangiography is becoming increasingly popular because of the advantages demonstrated by interventional cardiology. Many advantages of radial access could be applied to intraoperative angiography. OBJECTIVE: To report our institutional experience with transradial and transulnar intraoperative angiography, and evaluate its safety and feasibility. METHODS: Intraoperative angiography through upper extremity vessels was attempted in 70 consecutive patients between April 2019 and December 2022. Data on patient characteristics and surgical indications, procedural variables, and complications were collected. RESULTS: Of the 70 patients who underwent intraoperative angiography, 58.6% were female, and the mean age was 52.9 ± 14.0 years. The reason for surgery was aneurysm clipping in 42 (60.0%) cases. In total, 55 patients (78.6%) were positioned supine, 13 (18.6%) prone, and two (2.9%) were positioned three-quarters prone. Access was attempted via the radial artery in 60 (85.7%) patients and the ulnar artery in 10 (14.3%) patients. The procedure was successful in 69 of 70 cases (98.6%), as one required conversion to transfemoral approach due to significant spasm in the proximal right radial artery. The median fluoroscopy time was 8 min. No procedure was aborted, and no patient experienced access-site or angiography-related complications. Intraoperative angiography altered the surgical management in 3 (4.3%) cases. Re-access for follow-up angiography was unsuccessful in three (13.6%) of 22 due to radial artery occlusion. CONCLUSIONS: Our institutional experience supports that transradial and transulnar intraoperative angiography is safe and feasible during neurovascular procedures for various indications and positions.

Comparison of pipeline embolization device, flow re-direction endoluminal device and surpass flow diverters in the treatment of intracerebral aneurysms.

OBJECTIVES: The use of flow diversion for the treatment of intracranial aneurysms has gained broad acceptance. Three flow-diverting stents are approved by the Food and Drug Administration for use in the United States. We sought to compare the outcomes and safety profiles between the three devices at our institution. METHODS: A retrospective review of aneurysms treated with pipeline embolization device (PED), flow re-direction endoluminal device (FRED), and SURPASS was performed for aneurysms treated between 2018 and 2022 at our institution. RESULTS: The study cohort consisted of 142 patients. Precisely, 86 aneurysms were treated with a pipeline, 33 aneurysms were treated with FRED, and 23 aneurysms were treated with SURPASS. The 1-year complete occlusion rates were 59.4%, 60%, and 65%, respectively (0.91). Linear regression models found that only adjunctive coiling predicted aneurysm occlusion at 6 months (p = 0.02), but this effect was lost at 1 year and beyond. There was no significant difference in acute thrombotic or acute hemorrhagic complications between the three cohorts. There was a higher rate of delayed hemorrhagic complications in the SURPASS cohort (10%) compared to the PED (1.3%) and FRED (0%) cohorts (p = 0.04). There was also a higher rate of in-stent stenosis in the SURPASS cohort (20%) compared to the PED (5%) and FRED (3.1%) cohorts (p < 0.01). CONCLUSIONS: Treatment with PED, FRED, and SURPASS all resulted in similar complete occlusion rates at 6 months and 1 year. SURPASS was associated with higher in-stent stenosis as well as delayed hemorrhagic complications. Additional future studies evaluating the newest generation of flow-diverting stents with long-term follow-up will be necessary to make any definitive conclusions.

Incidence of mechanical thrombectomy among stroke patients brought directly to a comprehensive stroke center versus transfer from a primary stroke center in upstate New York.

BACKGROUND: Faster time to treatment for stroke is associated with improved outcomes. In cases of large vessel occlusion (LVO), standard of care treatment with thrombectomy can only be provided at a comprehensive stroke center (CSC). We examine the outcomes of patients who are directly brought to our center, a CSC, compared to those seen at a primary stroke center (PSC) and then transferred. METHODS: Patients with LVO presenting to our center from 1/1/2019 to 12/31/2019 were included. Cohorts of patients presenting first to a PSC and presenting first to a CSC were compared. Demographics and outcome metrics (Discharge Modified Rankin Scale (mRS) and National Institute of Health Stroke Severity Scale (NIHSS) scores) were obtained for all LVO patients. Imaging was also assessed. RESULTS: Of 864 stroke admissions, 346 had LVO (40%) with 183 (53%) transferring from a PSC and 163 (47%) presenting directly. Similar percentages of each cohort were taken for thrombectomy (25.1% transfer and 31.3% direct). However, as distance between PSC and CSC increased, likelihood of thrombectomy decreased. Transfer patients were more likely to be excluded from thrombectomy secondary to a large volume of complete stroke (p = 0.0001). Direct presenters had lower discharge mRS scores than transfer patients (p < 0.01), however, severity of stroke upon admission was similar in the two groups. CONCLUSION: Patients transferred from a PSC were more likely to have a worse outcome at time of discharge than those presenting directly to our center. Large volume of completed stroke was a frequent reason for exclusion from thrombectomy. Optimizing stroke protocols to CSC in cases of LVOs may result in better outcomes.

What matters most to cerebral aneurysms patients: A digital analysis of 1127 social media posts.

INTRODUCTION: Social media serves as a way for patients to post about their condition online, as well as for healthcare providers to disseminate information. Intrinsic bias exists exist when patients are given surveys by physicians or healthcare providers. We aim to investigate patient-centered social media posts regarding cerebral aneurysms on Instagram, Twitter, and TikTok. METHODS: Posts that included "brain aneurysm", "#brainaneurysm", "#brainaneurysmsurvivor", and "#aneurysmsurvivor" were queried on Instagram, Twitter, and TikTok. Any posts unrelated to the patient experience were excluded. Five hundred and fourteen Instagram posts, fourty tweets, and five hundred seventy three TikTok posts about the patient experience were identified. Posts were coded for the relevant themes related to their experience with the disease. RESULTS: Most posts made online were by women (892, 82.1%). Patients made the post most of the time (776, 67.5%), while other individuals posted less often (420, 36.5%). The most common themes on Instagram were survival (475, 87.3%), spreading positivity (385, 70.77%), and recovery/rehabilitation (329, 60.5%). TikTok users most often referred to survival (573, 97.1%), raising awareness (464. 78.6%), and spreading positivity (414, 70.2%). Patients were more likely to discuss pre-operative pain (p = 0.0382), postoperative pain (p < 0.0001), invisible illness (p = 0.0130), humor (p = 0.0028), recovery (p < 0.0001), angiograms (p < 0.0001), and resiliency (p < 0.0001) when compared to other individuals posting about a patients' experience. CONCLUSION: Patients often focus on different aspects of their care than do other individuals. This may be useful for physicians discussing treatment plans and prognoses with the patient and their families.

Enhanced recovery after surgery (ERAS) for craniotomies in the treatment of brain tumors: A systematic review.

INTRODUCTION: Postoperative complications after craniotomy for brain tumors include pain, nausea/vomiting, and infection. A standardized enhanced recovery after surgery (ERAS) protocol is not widely accepted for this common neurosurgical procedure. Few studies have explored its application. METHODS: A literature search of PubMed, Cochrane, and Google Scholar databases was performed between January 1992 and March 2023. Original studies that implemented an ERAS protocol for patients that underwent craniotomy for brain tumors were included. The following variables were evaluated: hospital length of stay (LOS), postoperative pain, postoperative nausea and vomiting (PONV) prophylaxis, non-opioid analgesia, and quality of life (QOL). RESULTS: Twelve studies with a total of 1309 patients met inclusion criteria, including ten randomized controlled trials, one nonrandomized controlled trial, and one quality control study. Most frequently assessed metrics included hospital LOS, PONV prophylaxis, and non-opioid analgesia. A significant reduction in postoperative LOS was observed in 7 studies with ERAS or ERAS components. ERAS was significantly associated with pain reduction on the visual analog scale and verbal numerical rating scale (n=8). Non-opioid analgesia in ERAS improved postoperative pain control (n=4) and decreased the duration of pain (n=1). Three of six studies found no difference in PONV in ERAS vs. control. No studies reported an increase in postoperative complications using ERAS vs. control. One study showed greater patient satisfaction at 30-day follow-up with improved QOL. CONCLUSION: Implementing ERAS protocol may enhance outcomes and quality of life in patients with moderate evidence for improved recovery in those undergoing craniotomy for brain tumors.

Intraoperative angiography via popliteal artery access for spinal neurovascular lesions: an institutional experience and systematic review.

BACKGROUND: Intraoperative DSA is used to confirm complete obliteration of neurovascular pathologies. For spinal neurovascular lesions, femoral access can be challenging given the need to flip the patient after sheath placement. Similarly, radial access can be complicated by arch navigation difficulties. Vascular access via the popliteal artery represents an appealing alternative option; however, data regarding its utility and efficacy in these cases are limited. METHODS: A retrospective series of four consecutive patients between July 2016 and August 2022 who underwent intraoperative spinal DSA via the popliteal artery was analyzed. Additionally, a systematic review was conducted to collect previously reported such cases. Collective patient demographics and operative details are presented to consolidate the available evidence supporting popliteal access. RESULTS: Four patients met the inclusion criteria from our institution. The systematic review yielded six previously published studies reporting 16 additional transpopliteal access cases. Of the 20 total cases (mean±SD age 60.8±17.2 years), 60% were men. Most treated lesions were dural arteriovenous fistulas (80%) located in the thoracic spine (55%) or cervical spine (25%). The left popliteal artery was most accessed and the highest visualized level was the craniocervical junction. All outcomes were either stable or improving after surgery, and no complications were observed. CONCLUSIONS: We report the safety and feasibility of transpopliteal access for intraoperative DSA in the prone position in four cases in addition to 16 previously reported cases in the literature. Our case series highlights popliteal artery access as an alternative to transfemoral or transradial access in this setting.

Removal of a Floating and Migrated Plate Screw in a Patient with a Failed Anterior Cervical Discectomy and Fusion.

BACKGROUND: Anterior cervical discectomy and fusion (ACDF) is a commonly performed procedure for degenerative cervical spine disease. Rare complications of ACDF surgery include hardware failure, in the form of screw loosening and migration, or rod breakage. We present a case in which we removed a migrated screw lodged in the esophagus from a patient with a failed anterior cervical fusion. OBJECTIVE: To present a surgical technique and considerations to remove a migrated screw. METHODS: The previous ACDF incision was reopened and exposure was gained under the guidance of a head and neck surgeon. Longus coli were mobilized off the spine bilaterally with electrocautery. After dissection, the screw was found lodged in the longitudinal muscle of the esophageal wall and excised with the use of a 15-blade. The integrity of the esophageal mucosa and submucosa was maintained and subsequently checked with rigid esophagoscopy. Fluoroscopy was used to confirm that all hardware was removed, with the exception of the anterior cages. RESULTS: The dislodged screw, which was embedded in the esophagus, was successfully removed. CONCLUSIONS: Failure of an ACDF carries a risk of screw migration, which may be asymptomatic even if the screw is lodged in the esophagus. Additional considerations are required with potential violations of the adjacent viscera.
