Perioperative management of antithrombotics in elective intracranial procedures: systematic review, critical appraisal.

PURPOSE: Perioperative management of patients medicated with antithrombotics requiring elective intracranial procedures is challenging. We ought to (1) identify the clinical practice guidelines (CPGs) and recommendations (CPRs) on perioperative management of antithrombotic agents in elective intracranial surgery and (2) assess their methodological quality and reporting clarity. METHODS: The study was conducted following the 2020 PRISMA guidelines for a systematic review and has been registered (PROSPERO, CRD42023415710). An electronic search was conducted using PubMed, Scopus, and Google Scholar. The search terms used were "adults," "antiplatelets," "anticoagulants," "guidelines," "recommendations," "english language," "cranial surgery," "brain surgery," "risk of bleeding," "risk of coagulation," and "perioperative management" in all possible combinations. The search period extended from 1964 to April 2023 and was limited to literature published in the English language. The eligible studies were evaluated by three blinded raters, by employing the Appraisal of Guidelines for Research & Evaluation II (AGREE-II) analysis tool. RESULTS: A total of 14 sets of guidelines were evaluated. Two guidelines from the European Society of Anaesthesiology and one from the American College of Chest Physicians found to have the highest methodological quality and reporting clarity according to the AGREE-II tool. The interrater agreement was good with a mean Cohens Kappa of 0.70 (range, 46.5-94.4%) in the current analysis. CONCLUSION: The perioperative management of antithrombotics in intracranial procedures may be challenging, complex, and demanding. Due to the lack of high quality data, uncertainty remains regarding the optimal practices to balance the risk of thromboembolism against that of bleeding.

Combined sclerotherapy followed by surgical resection of a large extracranial venous malformation in a 14-month-old child: preoperative workup and technical note.

INTRODUCTION: Venous malformations affect around 2 per 10,000 newborn and are the most common type of congenital vascular malformation. They are always present at birth and are often misdiagnosed with hemangiomas. Accurate diagnosis and adequate targeted therapy through a multidisciplinary approach is advocated for a successful treatment, considering a combination of modalities in complex cases. We present here the workup and treatment of a venous malformation in a 14 month old child by combining a preoperative sclerotherapy with sodium tetradecyl sulfate (STS) followed by complete surgical excision respecting the calvarium. CASE PRESENTATION: A large right extracranial fronto-parietal venous malformation and scalloping of the underlying calvarium, attached to the pericranium, surgically excised after preoperative sclerotherapy with STS in a 14-month-old child. RESULTS: The patient had an uneventful postoperative course with complete resection of the lesion, satisfying cosmetic appearance and no complications. Histopathological examination confirmed a venous malformation. CONCLUSION: We demonstrated the workup and the rationale of the combined sclerotherapy followed by surgical resection of a large growing extracranial venous malformation. Preoperative direct contrast injection and sclerotherapy allowed to rule out significative extracranial to intracranial venous inflow and reduce blood loss for the surgical procedure, respectively. Complete removal of the malformation minimized the impact on future growth of the calvarium.

Do overlapping neurosurgical procedures affect patient outcomes? A systematic review and meta-analysis.

Overlapping surgery (OS) is a common practice in neurosurgery that has recently come under scrutiny. This study includes a systematic review and meta-analysis on articles evaluating the effects of OS on patient outcomes. PubMed and Scopus were searched for studies that analyzed outcome differences between overlapping and non-overlapping neurosurgical procedures. Study characteristics were extracted, and random-effects meta-analyses were performed to analyze the primary outcome (mortality) and secondary outcomes (complications, 30-day readmissions, 30-day operating room returns, home discharge, blood loss, and length of stay). Mantel-Haenszel tests were completed for binary outcomes, whereas the inverse variance tests were conducted for continuous outcomes. Heterogeneity was measured using the I2 and X2 tests. The Egger's test was conducted to evaluate publication bias. Eight of 61 non-duplicate studies were included. Overall, 21,249 patients underwent non-OS (10,504 female) and 15,863 patients underwent OS (8393 female). OS was associated with decreased mortality (p = 0.002), 30-day returns to OR (p < 0.001), and blood loss (p < 0.001) along with increased home discharges (p < 0.001). High heterogeneity was observed for home discharge (p = 0.002) and length of stay (p < 0.001). No publication bias was observed. OS was not associated with worse patient outcomes compared to non-OS. However, considering multiple sources of limitation in the methodology of the included studies (such as limited number of studies, reports originating from mostly high-volume academic centers, discrepancy in the definition of "critical portion(s)" of the surgery across studies, and selection bias), extra caution is advised in interpretation of our results and further focused studies are warranted.

Theory-based implementation of an enhanced recovery protocol for cranial surgery.

OBJECTIVE: There is growing evidence for the use of enhanced recovery protocols (ERPs) in cranial surgery. As they become widespread, successful implementation of these complex interventions will become a challenge for neurosurgical teams owing to the need for multidisciplinary engagement. Here, the authors describe the novel use of an implementation framework (normalization process theory [NPT]) to promote the incorporation of a cranial surgery ERP into routine neuro-oncology practice. METHODS: A baseline audit was conducted to determine the degree of implementation of the ERP into practice. The Normalization MeAsure Development (NoMAD) questionnaire was circulated among 6 groups of stakeholders (neurosurgeons, anesthetists, intensivists, recovery nurses, preoperative assessment nurses, and neurosurgery ward staff) to examine barriers to implementation. Based on these findings, a theory-guided implementation intervention was delivered. A repeat audit and NoMAD questionnaire were conducted to assess the impact of the intervention on the uptake of the ERP. RESULTS: The baseline audit (n = 24) demonstrated limited delivery of the ERP elements. The NoMAD questionnaire (n = 32) identified 4 subconstructs of the NPT as barriers to implementation: communal specification, contextual integration, skill set workability, and relational integration. These guided an implementation intervention that included the following: 1) teamwork-focused training; 2) ERP promotion; and 3) procedure simplification. The reaudit (n = 21) demonstrated significant increases in the delivery of 5 protocol elements: scalp block (12.5% of patients before intervention vs 76.2% of patients after intervention, p < 0.00001), recommended analgesia (25.0% vs 100.0%, p < 0.00001) and antiemetics (12.5% vs 100.0%, p < 0.00001), trial without catheter (13.6% vs 88.9%, p < 0.00001), and mobilization on the 1st postoperative day (45.5% vs 94.4%, p < 0.00001). There was a significant reduction in the mean hospital length of stay from 6.3 ± 3.4 to 4.2 ± 1.7 days (p = 0.022). Two months after implementation, a repeat NoMAD survey demonstrated significant improvement in communal specification. CONCLUSIONS: Here, the authors have demonstrated the successful implementation of a cranial surgery ERP by using a systematic theory-based approach.

Preoperative frailty and 30-day mortality after resection of brain metastases: a multicenter surgical registry analysis of 11,038 patients.

OBJECTIVE: Surgery plays a key role in the management of brain metastases. Stratifying surgical risk and individualizing treatment will help optimize outcomes because there is clinical equipoise between radiation and resection as treatment options for many patients. Here, the authors used a multicenter database to assess the prognostic utility of baseline frailty, calculated with the Risk Analysis Index (RAI), for prediction of mortality within 30 days after surgery for brain metastasis. METHODS: The authors pooled patients who had been surgically treated for brain metastasis from the American College of Surgeons National Surgical Quality Improvement Program database (2012-2020). The authors studied the relationship between preoperative calculated RAI score and 30-day mortality after surgery for brain metastasis by using linear-by-linear proportional trend tests and binary logistic regression. The authors calculated C-statistics (with 95% CIs) in receiver operating characteristic (ROC) curve analysis to assess discriminative accuracy. RESULTS: The authors identified 11,038 patients who underwent brain metastasis resection with a median (interquartile range) age of 62 (54-69) years. The authors categorized patients into four groups on the basis of RAI: robust (RAI 0-20), 8.1% of patients; normal (RAI 21-30), 9.2%; frail (RAI 31-40), 75%; and severely frail (RAI ≥ 41), 8.1%. The authors found a positive correlation between 30-day mortality and frailty. RAI demonstrated superior predictive discrimination for 30-day mortality as compared with the 5-factor modified frailty index (mFI-5) on ROC analysis (C-statistic 0.65, 95% CI 0.65-0.66). CONCLUSIONS: The RAI frailty score accurately estimates 30-day mortality after brain metastasis resection and can be calculated online with an open-access software tool: https://nsgyfrailtyoutcomeslab.shinyapps.io/BrainMetsResection/. Accordingly, RAI can be utilized to measure surgical risk, guide treatment options, and optimize outcomes for patients with brain metastases. RAI has superior discrimination for predicting 30-day mortality compared with mFI-5.

Effect of powdered vancomycin on stopping surgical site wound infections in neurosurgery: A meta-analysis.

We performed a meta-analysis to evaluate the effect of powdered vancomycin on stopping surgical site wound infections in neurosurgery. A systematic literature search up to July 2022 was performed and 24 137 subjects with neurosurgery at the baseline of the studies; 10 496 of them were using the powdered vancomycin, and 13 641 were not using the powdered vancomycin as a control. Odds ratio (OR) with 95% confidence intervals (CIs) were calculated to assess the effect of powdered vancomycin on stopping surgical site wound infections in neurosurgery using dichotomous methods with a random or fixed-effect model. The powdered vancomycin had significantly lower surgical site wound infections after spinal surgery (OR, 0.53; 95% CI, 0.41-0.70, P < .001), deep surgical site wound infections after spinal surgery (OR, 0.45; 95% CI, 0.35-0.57, P < .001), superficial surgical site wound infections after spinal surgery (OR, 0.60; 95% CI, 0.43-0.83, P = .002), and surgical site wound infections after cranial surgery (OR, 0.37; 95% CI, 0.22-0.61, P < .001) compared to control in subjects with neurosurgery. The powdered vancomycin had significantly lower surgical site wound infections after spinal surgery, deep surgical site wound infections after spinal surgery, superficial surgical site wound infections after spinal surgery, and surgical site wound infections after cranial surgery compared to control in subjects with neurosurgery. The analysis of outcomes should be done with caution even though the low number of studies with low sample size, 3 out of the 42 studies, in the meta-analysis, and a low number of studies in certain comparisons.

Intralesional glucocorticoid treatment of an isolated intracranial juvenile xanthogranuloma: a case report.

Juvenile xanthogranuloma is a type of non-Langerhans cell histiocytic process that appears primarily in children and is described as a benign lesion. Although they typically present as a cutaneous lesion, it can also present in other areas including within the central nervous system. We report a 6-month-old infant who presented with seizure-like activity who was found to have a single intracranial mass within the right temporal area on magnetic resonance imaging of the head. The mass was biopsied and pathologically identified as a juvenile xanthogranuloma. In order to avoid the morbidity associated with a gross total resection, an intralesional steroid injection was utilized for treatment which our patient tolerated well. Intralesional steroid injection for the treatment of a symptomatic isolated intracranial juvenile xanthogranuloma has not been described but was successful for our patient.

The incidence of postoperative cerebrospinal fluid leakage after elective cranial surgery: a systematic review.

Cerebrospinal fluid (CSF) leakage is a major complication after elective neurosurgical procedures. The aim of this systematic literature review is to summarize the incidence rates of postoperative cerebrospinal fluid leakage for neurosurgical procedures, classified by surgical approach. The Pubmed, Cochrane, Embase, and Web of Science databases were searched for studies reporting the outcome of patients undergoing elective neurosurgical procedures. The number of patients, surgical approach, and indication for surgery were recorded for each study. Outcomes related to CSF leakage such as clinical manifestation and treatment were reported as well. One hundred and thirteen studies were included, reporting 94,695 cases. Overall, CSF leaks were present in 3.8% of cases. Skull base surgery had the highest rate of CSF leakage with 6.2%. CSF leakage occurred in 5.9% of anterior skull base procedures, 6.4% of middle fossa, and 5.2% of transpetrosal surgeries. 5.8% of reported infratentorial procedures were complicated by CSF leakage versus 2.9% of supratentorial surgeries. CSF leakage remains a common serious adverse event after cranial surgery. There exists a need for standardized procedures to reduce the incidence of postoperative CSF leakage, as this serious adverse event may lead to increased health care costs.

Pharmacological venous thromboembolism prophylaxis in elective cranial surgery: a systematic review of time of initiation, regimen and duration.

INTRODUCTION: Pharmacological prophylaxis of venous thromboembolism (VTE) requires nuanced decision-making to balance the risk of VTE against haemorrhage. This problem is compounded in neurosurgical patients, in whom postoperative intracranial haemorrhage (ICH) may be catastrophic, compared to non-neuraxial bleeding in other types of surgery. Current major guidelines recommend caution when using pharmacological prophylaxis in elective cranial surgery, but incorporate low-quality evidence and lack precise guidance on timing and duration of anticoagulation. METHODS: We aimed to answer the following questions for patients undergoing elective cranial surgery: (1) when is the optimal time to initiate postoperative anticoagulation, and (2) how long should postoperative anticoagulation be continued for? In this systematic review, we screened randomised and non-randomised studies reporting original data on pharmacological VTE prophylaxis in elective cranial surgery. Outcomes of interest were VTE and ICH. RESULTS: Three retrospective, single-centre observational studies met eligibility criteria, with a total of 923 participants. Meta-analysis was not performed due to a high risk of bias across all studies. Through narrative synthesis, we found that patients who developed VTE were significantly more likely to receive their first postoperative dose at a later time (mean: 144 vs. 29 h, p = .04). Shorter courses of anticoagulation (<7 days) were associated with significantly lower ICH rates (p = .03) compared to longer courses (>21 days). CONCLUSION: The limited evidence favours earlier initiation and shorter courses of thromboprophylactic anticoagulation. These findings are specific to patients undergoing surgery for meningioma or glioma and may not apply to other populations. Randomised controlled trials or robustly designed observational studies are necessary to establish a clearer evidence base.

Elevated body mass index facilitates early postoperative complications after surgery for intracranial meningioma.

Surgical resection represents the primary treatment option for patients suffering from intracranial meningioma. However, early postoperative complications significantly worsen initial favorable postoperative outcomes. Therefore, the ability to preoperatively assess potential risk factors for early postoperative unfavorable events is important to preselect critical patients who might require special attention during clinical management. In the current study, we therefore analyzed our institutional database in order to identify risk factors associated with early postoperative complications after initial meningioma resection. Between 2014 and 2017, 202 patients with intracranial supratentorial meningioma were surgically treated at the authors' institution. Early postoperative complications were defined as any postoperative event requiring further surgical measures within 30 days following initial meningioma resection. A multivariate analysis was performed to identify independent risk factors associated with postoperative complications after surgical meningioma therapy. Overall, 13 out of 202 meningioma patients developed early postoperative complications (6%). The multivariate analysis revealed obesity in terms of elevated body mass index (BMI ≥ 30 kg/m2) (p = 0.03), the presence of atrial fibrillation (p = 0.001) as well as the preoperative Karnofsky Performance Status Scale < 70% (p = 0.004) as independent predictors for early postoperative complications in the course of supratentorial meningioma resection. Obesity is associated with a higher risk of postoperative unfavorable events that require further surgical treatment. Furthermore, the present study identifies several additional risk factors for the development of early postoperative complications after intracranial meningioma resection enabling to preoperatively select for high-risk patients that might require special attention in clinical and surgical management.

Preliminary experience with a digital robotic exoscope in cranial and spinal surgery: a review of the Synaptive Modus V system.

BACKGROUND: The microscope is the standard tool for microneurosurgery worldwide. However, the reduced illumination of the surgical field with the use of a conventional microscope during surgeries of deeply located pathologies remains unaddressed. Accordingly, different exoscope systems have recently been introduced in clinical practice. Here, we report our initial experience with the digital 2-dimensional Synaptive Modus V exoscope system in spinal and cranial surgery. METHODS: During a 2-week period between 27 September to 11 October 2018, we used the Synaptive Modus V exoscope system and performed eight neurosurgical procedures including spine (n = 4) and cranial procedures (n = 4). Visual quality, depth perception, complications, switching to microscope comfort level of the surgeon, and learning curve during surgery were evaluated. RESULTS: A total of eight procedures were performed, namely, vestibular schwannoma (n = 1), skull base meningioma (n = 1), olfactory groove meningioma (n = 1), tentorial meningioma (n = 1), anterior cervical discectomy (n = 1), cervical laminectomy (n = 1), and lumbar disc herniation (n = 2). The overall results were comparable to the operative microscope with better visual quality and greater comfort for the surgeon. CONCLUSION: The Synaptive Modus V system is a safe tool to perform common spinal surgeries and intracranial tumor resection. Image quality is better than a microscope but with slightly less depth perception. Vigorous training in the laboratory may be helpful before clinical use.

The implementation of an infection prevention bundle reduces surgical site infections following cranial surgery.

BACKGROUND: The benefit of an infection prevention bundle made up of five basic procedures to avoid surgical site infections (SSIs) following cranial surgery was evaluated. METHODS: Data from all patients with first time elective brain surgery from March 2014 till May 2016 were analyzed. In April 2015, an infection prevention bundle was implemented. The rate of SSIs after first time elective cranial surgery of patients operated 1 year before and 1 year after the implementation was compared. RESULTS: Of the 321 cases operated before the implementation of the infection prevention bundle, 13 cases (4%) developed a SSI. After the implementation, only 6 patients out of 288 were re-operated due to a SSI (2%). The most frequent etiological germ cultivated was Staphylococcus aureus. CONCLUSION: The implementation of a bundle of 5 basic infection prevention steps leads to a clinical relevant reduction of SSIs.

Pediatric cerebral sinovenous thrombosis following cranial surgery.

PURPOSE: Pediatric cerebral sinovenous thrombosis (CSVT) is an important, though less common subtype of pediatric stroke. It has been linked to several risk factors, including cranial procedures, with few studies highlighting this relationship. The aim of this study was to characterize the diagnosis and treatment of CSVT after cranial surgery. METHODS: An institutional pediatric stroke research database was used to identify all CSVT cases diagnosed within 30 days of cranial surgery from November 2004 to December 2014. Thirteen subjects were retrospectively analyzed for clinical presentation, surgical details, radiographic characteristics, laboratory study results, treatment, and outcome. Diagnostic testing and treatment adhered to a consensus-based institutional stroke protocol. RESULTS: Cranial vault reconstruction, subdural empyema evacuation, and tumor resection were each observed in three subjects. Eleven (85%) subjects had sinus exposure during surgery, and eight (73%) developed thrombus in a sinus within or adjacent to the operative field. Two (15%) had documented iatrogenic sinus injury. On post-operative testing, ten (77%) subjects had prothrombotic abnormalities. Seven (54%) were treated with anti-coagulation therapy (ACT) starting on a median of post-operative day (POD) 3 (IQR 1-3) for a median of 2.9 months (IQR 2.4-5.4). Median time to imaging evidence of partial or complete recanalization was 2.4 months (IQR 0.7-5.1). No symptomatic hemorrhagic complications were encountered. CONCLUSIONS: Pediatric CSVT may be encountered after cranial surgery, and decisions related to anti-coagulation are challenging. The risk of CSVT should be considered in pre-surgical planning and post-operative evaluation of cases with known risk factors. In our study, judicious use of ACT was safe in the post-operative period.

Nonshaved cranial surgery in black Africans: technical report and a medium-term prospective outcome study.

Nonshaved neurosurgery, cranial or spinal, is well reported among Caucasians but hardly among native Africans. The ungroomed scalp hairs of black Africans have unique anthropological characteristics needing special attention for shaveless cranial surgery. A technical report of the execution of this surgical procedure among an indigenous patient population in a sub-Sahara African country is presented, as well as an outcome analysis in a prospective cohort over a 7-year period. A total of 303 patients (211 males, 70 %) fulfilled the criteria for this study. The surgical procedure was primary in 278 (92 %) and redo in 8 %. It was emergency surgery in 153 (51 %). They were trauma craniotomies or decompressive craniectomies in 95 cases (31 %), craniotomies for tumour resections in 86 (28 %), and the surgical dissections for other conditions in 122 (41 %). The duration of surgery ranged from 30 min to 8.5 h, mean 2.5 (SD, 1.6), median 2. In-hospital clinical outcome was good (normal status or moderate deficit on dichotomized Glasgow outcome scale (GOS)) in 273 (90.1 %) cases while surgical site infections occurred in only 10 cases (3.3 %). The type of surgery, redo or primary, did not have any significant association with the in-hospital outcome (p = 0.5), nor with the presence of surgical site infection (SSI) (p = 0.7). The length of follow-up ranged from 2 to 63 months (mean, 7) with no untoward complications reported so far. Medium-term outcome of nonshaved neurosurgery in this indigenous black Africans remains favourable with no attendant significant adverse after-effects.

'Noises in the head': a prospective study to characterize intracranial sounds after cranial surgery.

BACKGROUND: Patients often report sounds in the head after craniotomy. We aim to characterize the prevalence and nature of these sounds, and identify any patient, pathology, or technical factors related to them. These data may be used to inform patients of this sometimes unpleasant, but harmless effect of cranial surgery. METHODS: Prospective observational study of patients undergoing cranial surgery with dural opening. Eligible patients completed a questionnaire preoperatively and daily after surgery until discharge. Subjects were followed up at 14 days with a telephone consultation. RESULTS: One hundred fifty-one patients with various pathologies were included. Of these, 47 (31 %) reported hearing sounds in their head, lasting an average 4-6 days (median, 4 days, mean, 6 days, range, 1-14 days). The peak onset was the first postoperative day and the most commonly used descriptors were 'clicking' [20/47 (43 %)] and 'fluid moving' in the head [9/47 (19 %)]. A significant proportion (42 %, 32/77) without a wound drain experienced intracranial sounds compared to those with a drain (20 %, 15/74, p < 0.01); there was no difference between suction and gravity drains. Approximately a third of the patients in both groups (post-craniotomy sounds group: 36 %, 17/47; group not reporting sounds: 31 %, 32/104), had postoperative CT scans for unrelated reasons: 73 % (8/11) of those with pneumocephalus experienced intracranial sounds, compared to 24 % (9/38) of those without pneumocephalus (p < 0.01). There was no significant association with craniotomy site or size, temporal bone drilling, bone flap replacement, or filling of the surgical cavity with fluid. CONCLUSIONS: Sounds in the head after cranial surgery are common, affecting 31 % of patients. This is the first study into this subject, and provides valuable information useful for consenting patients. The data suggest pneumocephalus as a plausible explanation with which to reassure patients, rather than relying on anecdotal evidence, as has been the case to date.

The effects of different types of hair shaving on the body image and surgical site infection in elective cranial surgery.

AIMS AND OBJECTIVES: To investigate the effects of different types of shaving on body image and surgical site infection in elective cranial surgery. BACKGROUND: Hair shaving before cranial surgery is commonly performed in many countries. However, the impact of shaving on the patients' body image and surgical site infection is not, as yet, well investigated. DESIGN: A randomised-controlled design was used in this study. METHODS: The sample comprised 200 patients who underwent elective cranial surgery between March 2013-August 2014. The Center for Disease Control and Prevention criteria were applied for the preoperative preparation of patients and for the follow-up of surgical site infection. Wound swab cultures were obtained four times from all patients. The Social Appearance Anxiety Scale was used to assess changes in the body image of patients. FINDINGS: The rate of surgical site infection was 1% for each group and for all patients. There was no difference between the groups of surgical site infection. Coagulase-negative staphylococci and Staphylococcus epidermidis were mostly isolated in the swab cultures. The Social Appearance Anxiety Scale score decreased in patients who underwent strip shaving and increased in patients with regional shaving. CONCLUSION: There is no difference between strip shaving and regional shaving in the development of surgical site infection after cranial surgery. In addition, regional hair shaving negatively affects the patients' body image. RELEVANCE TO CLINICAL PRACTICE: Findings of this study provide useful evidence-based information for healthcare professionals. The development and implementation of effective interventions result in the prevention of surgical site infection and improvement of the patients' body image in elective cranial surgery.

The Lenticular.

OBJECTIVE: The lenticular was an instrument introduced by Galen to facilitate cutting the bone of the cranium. Illustrations of the instrument first appeared in the 16th century during the Renaissance. These illustrations have been widely used, but the instrument's shape seems ill-adapted to its function. Archaeological research in Rimini, Italy, unearthed a similar instrument with a shape that seems more suitable for the function of cutting cranial bone. The object of this study was to evaluate the efficacy of these two instruments for cutting the bone of the cranium. METHODS: Replicas of the two instruments were obtained. Trepanation was performed in the left parietal region of a sheep's head. In addition, the application of the instruments in the literature was analyzed. RESULTS: The Roman lenticular cut the cranium with ease. The Renaissance instrument failed to cut the bone and only separated the dura mater from the bone. The lenticular had been used to cut bone up to the 13th century. In contrast, the Renaissance instrument was not used to cut bone but to smooth roughened bony surfaces and to remove spicules of bone that were in contact with the dura. CONCLUSIONS: Analysis of illustrations in medical publications should be undertaken with the same rigor as applied to analysis of text.

Enhanced Recovery after Cranial Surgery in Elderly: A Review.

BACKGROUND: Enhanced recovery after surgery (ERAS) is a multidisciplinary approach aimed at reducing the length of hospital stay, improving patient outcomes, and reducing the overall cost of care. Although ERAS protocols have been widely adopted in various surgical fields, their application in cranial surgery remains relatively limited. METHODS: Considering that the aging of the population presents significant challenges to healthcare systems, and there is currently no ERAS protocol available for geriatric patients over the age of 65 requiring cranial surgery, this article proposes a new ERAS protocol for this population by analyzing successful ERAS protocols and optimal perioperative care for geriatric patients described in the literature. RESULTS: Our aim is to develop a feasible, safe, and effective protocol for geriatric patients undergoing elective craniotomy, which includes preoperative, intraoperative, and postoperative assessments and management, as well as outcome measures. CONCLUSIONS: This multidisciplinary and evidence-based ERAS protocol has the potential to reduce perioperative morbidity, improve functional recovery, and enhance postoperative outcomes after cranial surgery in elderly. Further research will be necessary to establish strict guidelines.

A Case of Pott's Puffy Tumor in a Patient With Eosinophilic Chronic Rhinosinusitis.

Eosinophilic chronic rhinosinusitis (ECRS) is a refractory type 2 inflammation-based airway allergic disease that is prone to complications such as bronchial asthma. Pott's puffy tumor (PPT) is a rare clinical entity characterized by osteomyelitis of the frontal bone accompanied by a subperiosteal abscess. A 56-year-old female with a history of cranial surgery and bronchial asthma presented to an otolaryngology clinic with nasal obstruction and loss of smell, later developing swelling and redness on her forehead. She was diagnosed and treated for ECRS and was thought to have developed PPT during her course. Nasal endoscopy reveals bilateral polyp formation originating from the middle meatus. Paranasal computed tomography (CT) indicates substantial swelling extending from the opening of the frontal sinus to the adjacent subcutaneous tissue, accompanied by a defect in the frontal bone and osteolysis at the base of the frontal skull. Her management included conservative antibiotic therapy adjusted due to a drug eruption and, subsequently, endoscopic sinus surgery (ESS). The case was complicated by the patient's medical history and the absence of detailed surgical records, which limited the use of enhanced imaging techniques. This underscores the complexity of diagnosing and managing PPT in adults, particularly those with prior surgeries, emphasizing the need for a tailored diagnostic and therapeutic approach that integrates detailed patient history with current clinical indicators to effectively guide treatment. This case contributes to the limited literature on adult PPT and underscores the critical need for careful patient monitoring and detailed surgical history.

Role of decompressive craniectomy in the management of acute ischemic stroke (Review).

The application of decompressive craniectomy (DC) is thoroughly documented in the management of brain edema, particularly following traumatic brain injury. However, an increasing amount of concern is developing among the universal medical community as regards the application of DC in the treatment of other causes of brain edema, such as subarachnoid hemorrhage, cerebral hemorrhage, sinus thrombosis and encephalitis. Managing stroke continues to remain challenging, and demands the aggressive and intensive consulting of a number of medical specialties. Middle cerebral artery (MCA) infarcts, which consist of 1-10% of all supratentorial infarcts, are often associated with mass effects, and high mortality and morbidity rates. Over the past three decades, a number of neurosurgical medical centers have reported their experience with the application of DC in the treatment of malignant MCA infarction with varying results. In addition, over the past decade, major efforts have been dedicated to multicenter randomized clinical trials. The present study reviews the pertinent literature to outline the use of DC in the management of malignant MCA infarction. The PubMed database was systematically searched for the following terms: 'Malignant cerebral infarction', 'surgery for stroke', 'DC for cerebral infarction', and all their combinations. Case reports were excluded from the review. The articles were categorized into a number of groups; the majority of these were human clinical studies, with a few animal experimental clinical studies. The surgical technique involved was DC, or hemicraniectomy. Other aspects that were included in the selection of articles were methodological characteristics and the number of patients. The multicenter randomized trials were promising. The mortality rate has unanimously decreased. As for the functional outcome, different scales were employed; the Glasgow Outcome Scale Extended was not sufficient; the Modified Rankin Scale and Bathel index, as well as other scales, were applied. Other aspects considered were demographics, statistics and the very interesting radiological ones. There is no doubt that DC decreases mortality rates, as shown in all clinical trials. Functional outcome appears to be the goal standard in modern-era neurosurgery, and quality of life should be further discussed among the medical community and with patient consent.
