Purpose: This study explores the protective capabilities of bicycle helmets on serious head injury among bicyclists hospitalized in a Norwegian level 1 trauma centre. Method: Information on helmet use, demographic variables, Abbreviated Injury Scale (AIS) and surgical procedure codes was retrieved from the Oslo University Hospital Trauma Registry for patients with bicycle-related injuries from 2005 through 2016. Outcomes were serious head injury defined as maximum AIS severity score ≥ 3 in the AIS region Head, any cranial neurosurgical procedure, and 30-day mortality. Results: A total of 1256 hospitalized bicyclists were included. The median age was 41 years (quartiles 26–53), 73% were male, 5.3% had severe pre-injury comorbidities, and 54% wore a helmet at the time of injury. Serious head injury occurred in 30%, 9% underwent a cranial neurosurgical procedure, and 30-day mortality was 2%. Compared to non-helmeted bicyclists, helmeted bicyclists were older (43 years, quartiles 27–54, vs. 38 years, quartiles 23–53, p = 0.05), less often crashed during night-time (21% vs. 38%, p < 0.001), less frequently had serious head injury (22% vs. 38%, OR 0.29, 95% CI 0.22–0.39), and less often underwent cranial neurosurgery (6% vs. 14%, OR 0.36, 95% CI 0.24–0.54). No statistically significant difference in 30-day mortality between the two groups was found (1.5% vs. 2.9%, OR 0.50, 95% CI 0.22–1.11). Conclusion: Helmet use was associated with fewer and less severe head injuries and fewer neurosurgical procedures. This adds evidence to the protective capabilities of bicycle helmets.

This case report highlights the diagnostic and therapeutic journey of a 16-year-old female presenting with chronic headaches, ultimately diagnosed with anaplastic meningioma. Despite its rarity in pediatric patients, anaplastic meningioma necessitates swift recognition and management due to its aggressive nature. Imaging findings, including CT and MRI, initially suggested a provisional diagnosis of hemangiopericytoma, emphasizing the diagnostic challenge posed by this condition. Surgical intervention revealed unexpected histopathological findings, highlighting the importance of thorough evaluation. Treatment involved frontal craniectomy and excision followed by adjuvant radiotherapy. While the patient's postoperative course was uneventful, histopathology confirmed the presence of anaplastic meningioma, leading to the adjustment of her clinical management. This case shows the need for heightened suspicion and comprehensive evaluation in similar presentations to facilitate timely intervention and improve patient outcomes.

The ophthalmic artery normally travels with the optic nerve through the optic canal. However, sometimes, the ophthalmic artery travels through a foramen within the optic strut named an accessory optic canal, double optic canal, or ophthalmic canal. This variant puts individuals at an increased risk for blindness or death during anterior clinoidectomy due to unforeseen hemorrhage of the ophthalmic artery or internal carotid artery when the optic strut is separated from the body of the sphenoid bone. Several features make the accessory optic canal difficult to recognize on imaging: its variant nature, small size, and ability to masquerade as a caroticoclinoid foramen or a pneumatized sphenoidal structure. Hence, improved methods of presurgical identification are warranted. The aim of this study was to assess the size and shape of the optic canal, with and without a concomitant accessory optic canal, to determine whether measurement of the optic canal may provide useful information regarding the presence of an accessory optic canal. In 191 dry crania, optic canals with and without concomitant accessory optic canals were assessed for the following parameters: canal area, canal perimeter, circularity, solidity, the axes and aspect ratio of a best-fit ellipse, and roundness. Normal optic canals were found to have a larger area (P = 0.036), perimeter (P = 0.043), and minor axis of a best-fit ellipse (P = 0.031) than the optic canals that occurred alongside accessory optic canals. Asymmetry in optic canal size can help indicate the presence of a unilateral accessory optic canal before surgery. [ABSTRACT FROM AUTHOR]

Simulation training is an educational tool that provides technical and cognitive proficiency in a risk-free environment. Several models have recently been presented in Latin America and the Caribbean (LAC). However, many of them were presented in non-indexed literature and not included in international reviews. This scoping review aims to describe the simulation models developed in LAC for neurosurgery training. Specifically, it focuses on assessing the models developed in LAC, the simulated neurosurgical procedures, the model's manufacturing costs, and the translational outcomes. Simulation models developed in LAC were considered, with no language or time restriction. Cadaveric, ex vivo, animal, synthetic, and virtual/augmented reality models were included for cranial and spinal procedures. We conducted a review according to the PRISMA-ScR, including international and regional reports from indexed and non-indexed literature. Two independent reviewers screened articles. Conflicts were resolved by a third reviewer using Covidence software. We collected data regarding the country of origin, recreated procedure, type of model, model validity, and manufacturing costs. Upon screening 917 studies, 69 models were developed in LAC. Most of them were developed in Brazil (49.28%). The most common procedures were related to general neurosurgery (20.29%), spine (17.39%), and ventricular neuroendoscopy and cerebrovascular (15.94% both). Synthetic models were the most frequent ones (38.98%). The manufacturing cost ranged from 4.00 to 2005.00 US Dollars. To our knowledge, this is the first scoping review about simulation models in LAC, setting the basis for future research studies. It depicts an increasing number of simulation models in the region, allowing a wide range of neurosurgical training in a resource-limited setting. [ABSTRACT FROM AUTHOR]

Background Animal models are commonly used to assess the efficacy of new materials to be employed in the surgical repair of a nerve injury. However, there is no published surgical repair protocol for sciatic nerve neurotmesis in rats.

Purpose: The purpose of this study was to evaluate the clinical usefulness of zero-echo-time (ZTE)–based magnetic resonance imaging (MRI) in planning the optimum surgical approach and applying ZTE for anatomical guidance during transcranial surgery. Methods: Eleven of 26 patients who underwent transcranial surgery and carotid endarterectomy and in whom ZTE-based MRI and magnetic resonance angiography (MRA) data were obtained were analyzed by creating ZTE/MRA fusion images and 3D ZTE-based MRI models. We examined whether these images and models can be substituted for computed tomography imaging for neurosurgical procedures. Furthermore, the clinical usability of the 3D ZTE-based MRI models was evaluated by comparing them with actual surgical views. Results: Zero-echo-time/MRA fusion images and 3D ZTE-based MRI models clearly illustrated the cranial and intracranial morphology without radiation exposure or the use of iodinated contrast medium. The models allowed determination of the optimum surgical approach to cerebral aneurysms, brain tumors near the brain surface, and cervical internal carotid artery stenosis by visualizing the relationship of lesions with adjacent bone structures. However, ZTE-based MRI did not provide useful information for surgery for skull base lesions such as vestibular schwannoma because bone structures of the skull base often include air components, which cause signal disturbance in MRI. Conclusions: Zero-echo-time sequences on MRI allowed distinct visualization of not only bone but also vital structures around the lesion. This technology has low invasiveness for patients and was useful for preoperative planning and guidance of the optimum approach during surgery in a subset of neurosurgical diseases.

Remote cerebellar hemorrhage (RCH) is a rare complication of neurosurgical procedures and is characterized by a typical bleeding pattern defined as the “zebra sign.” Only few cases of RCH have been reported in the English literature, and its patho-physiology remains unclear. In this report, we present the cases of three patients with RCH after three different procedures: burr-hole trephination and chronic subdural hematoma evacuation of bilateral cerebral convexity with subsequent subdural drain insertion, lumbar drainage for cerebrospinal fluid divergence for thoracic endovascular aortic repair, and combined bypass surgery for moyamoya disease.

Clinical practice guideline on anticoagulation is intended to manage patients undergoing neurosurgical procedures for the best possible short and long-term outcomes. In the clinical office practice, anticoagulation is offered to prevent thromboembolism with Warfarin, Heparin, Novel Oral Anticoagulants. The management approach starts with the mitigation plans from a reversal of preprocedural anticoagulants for impending neurosurgical procedures by estimating procedural bleeding risk on the patients. The haemorrhage criteria and the timing of procedures are best assessed by the proceduralist during and after the intervention, standing on ground situations. Yet, intra- and post-procedure anticoagulant therapy should induct a multidisciplinary consultation paradigm for the best outcome in any emergent scenario. Further, each anticoagulation event should be monitored closely with competence in the optimum reversal process. Different neurosurgical procedures also should be weighed for their inherent hazards along with the probabilities of the bleeding and thromboembolism. The treating team should also concur to suggest a resumption of the pre-procedure anticoagulant therapy which may have been in place for altogether different morbidities. Regarding the anticoagulant agent, there are special conditions and recommendations to bear in mind in the daily medical practice for patient management. In the clinical practice guidelines for neurosurgical procedures, decisions about initiation and continuation of anticoagulants require experience and thorough internalization of the planned procedure, to avoid the risks of inherent risks of bleeding and thromboembolism.

Background: To measure the degree of relative ischemia caused by skin closure, we explored the potential utility of intraoperative surface blood flow measurement with laser speckle imaging (LSI). Methods: Prospective observational study of eight subjects that underwent intraoperative LSI during elective cranial neurosurgical procedures at the time of skin closure. Results: Seven 1st time incisions, with closure techniques including sutures (n = 3), staples (n = 3), and one after galeal sutures. When compared to the control region, there was a mean 63.7% reduction in flow across all seven subjects (range 18.7-95.32%). Comparing by closure type, a higher flow reduction in the three subjects with suture closure (80.7% reduction) compared to staples (61.9% reduction, P = 0.0379). One subject had a complex wound where tightening and loosening of sutures were performed to ensure adequate perfusion. Suturing resulted in significantly more local decreased flow compared to staples (P < 0.0001). Conclusion: These findings demonstrate the relative feasibility of using LSI for preoperative vascular flow assessment in planning complex incision closure. These data also provide preliminary support for the hypothesis that skin closure itself causes relative ischemia compared to deep approximation or cautery of the skin edge and that the relative ischemia from staples closure is generally less than from suture closure.

Abstract Background Peripheral nerves are constant targets of traumatic injury which may result in neurotmesis and which invariably requires surgical treatment. In view of this, tissue engineering studies developed biomaterials which were first tested in animal models and used as a guide for nerve stumps in the procedure in order to speed up the healing process. Therefore, the aim of this study is to evaluate the efficacy of biomaterials used in tubing technique on healing and histological and functional recovery after peripheral nerve neurotmesis in rats. Methods We will search PubMed/MEDLINE, Embase, Web of Science, LILACS, and CENTRAL (from inception onwards). Grey literature will be identified through searching dissertation databases, guidelines, policy documents, and reports. We will include randomized and non-randomized trials conducted in young adult rats with peripheral neurometsis undergoing surgical repair through tubing technique with biomaterials. Primary outcomes will be histomorphometry, immunohistochemistry of the nerve tissue, and sciatic functional index. Secondary outcome will be nerve macroscopic evaluation. Two reviewers will independently screen all citations, full-text articles, and abstract data. Potential conflicts will be resolved through discussion. The methodological quality (or risk of bias) of individual studies will be appraised using an appropriate tool. If feasible, we will conduct random effects meta-analysis. Discussion This systematic review of animal studies will identify, evaluate, and synthetize the evidence on the the efficacy of tubing technique with biomaterials compared to direct coaptation technique after peripheral neurotmesis in nerve healing and return to functionality.

Objective To explore the solutions for microsurgical resection of anterior clinoid meningiomas（ ACMs）, including the technical details and effect evaluation of optic nerve decompression and falciform ligament resection. Methods The clinical data of 80 patients with ACMs were analyzed retrospectively. Results Rate of total removal was 87. 5%,near-total removal10%,subtotal removal 3%. Anterior clinoid processes were removed in 33 cases. Visual acuity improvement in 38 cases, including enlargement of visual field. Visual acuity unchanged in 34 cases, aggravated in 8 cases. Another 3 cases lost vision before operation and didn’t recover after operation. The reasons of subtotal tumor removal were strictly incasement of ICA or its perforators and involvement of CS. Conclusions The core of the operation is to protect the optic nerve, internal carotid artery and its main branches. To achieve tumor decompression, ligament decompression, bone decompression and vascular decompression of the optic nerve, bone decompression of the optic canal and resection of the tumor in the canal are important factors for total resection and improvement of vision. Stereotactic radiosurgery can also control the residual tumor. [ABSTRACT FROM AUTHOR]

Bacterial meningitis is a medical emergency that requires prompt identification and treatment in the emergency department (ED). Medical management is the mainstay of treatment. However, some patients may require neurosurgical intervention. Furthermore, neurological complications may develop, causing significant morbidity and mortality. We present a case report of a 42-year-old Chinese gentleman who presented to the ED and was subsequently diagnosed with pneumococcal meningitis. In addition to routine medical management, he also underwent emergent extraventricular drainage procedure to alleviate increased intracranial pressure. He subsequently developed stroke, seizure and sensorineural hearing loss. Not seizure-related hearing loss. After a comprehensive rehabilitation program, he showed good response and recovered without focal neurological deficit. A high index of suspicion and timely interventions in ED are important in minimizing morbidity and mortality from bacterial meningitis. The help of neurosurgeons may be necessary in selected cases. Dexamethasone has an important role in the prevention of neurological complications, as well as in their treatment.

Objective To study the effect of fluorescein sodium ( FLS ) "yellow fluorescence" staining in guiding glioblastoma ( GEM) surgery and its relationship with clinical factors. Methods The clinical data of 24 patients with GEM were analyzed retrospectively, and the clinical data of Han and minority patients were compared. The patients were intravenously injected with fluorescein sodium staining during the operation. The samples were taken from the yellow staining boundary and the non yellow staining area within 0.5 cm outside the yellow staining boundary for pathological examination. The degree of tumor cell infiltration was observed to determine the tumor boundary and guide the operation to remove the tumor. The tumor volume was compared to determine the extent of tumor resection before and after operation. KPS scores were evaluated before operation, I week and I month after operation. Spearman rank correlation was used to analyze the correlation between the degree of tumor resection, pathological changes in the non yellow stained area around the tumor and clinical factors. Results There was no significant difference in clinical data between Han and minority patients. In this group of patients, histopathological examination of tumor yellow staining boundary showed that 19 patients were GEM, 3 patients were microgliosis, 2 were anaplastic astrocytoma. Histopathological examination of tumor without yellow staining area showed that 22 were GBM, 2 patients were diffuse astrocytoma. The tumors were totally resected in 16 and subtotally resected in 8. One month after operation, compared with preoperative KPS score, 17 were improved, 3 were unchanged, and 4 were aggravated. There was a negative correlation between the degree of tumor resection and the location of tumor involving basal ganglia nuclei and ventricles ( r = - 0.84, P<0.05) . There was a negative correlation between the histopathological changes of no yellow staining area around tumor and 1P19 Q ( r = - 0.44, P <0.05 ) . Conclusion FLS " yellow fluorescence" staining technology can effectively guide the resection of GBM in real time during operation, improve the resection rate and prognosis of patients. The degree of tumor resection is related to the tumor location, and the pathological changes of non yellow staining area around the tumor are related to 1P19Q. [ABSTRACT FROM AUTHOR]

Objective: To report on combined surgical and/or endovascular procedures for cerebrovascular disease in a hybrid operating room (OR). Methods: Between October 2016 and June 2020, 1832 neurosurgical procedures were performed in a hybrid OR. Our institution's hybrid OR consists of a multi-axis robotic C-arm monoplane digital subtraction angiography (DSA) system with an operating table, 3D-rotational DSA, cone-beam computed tomography (dyna CT), and real-time navigation software. Procedures were categorized into six categories according to purpose: (1) simple diagnosis and follow-up, (2) simple endovascular procedure, (3) combination of surgery and endovascular procedures, (4) rescue surgery after endovascular procedures, (5) frameless stereotactic procedure, and (6) other surgeries requiring C-arm. Results: Of 1832 neurosurgical procedures in the hybrid OR, 1430 were simple diagnosis and follow-up cases, 330 simple endovascular procedures, 8 combination of surgery and endovascular procedures, 15 rescue after endovascular procedure, 40 frameless stereotactic procedures, and 9 other surgeries. Eight cases of combination of surgery and endovascular procedures, safely performed without wasting time on patient transfer, were performed in seven bypass end endovascular procedures and one case of bow-hunter syndrome in complex cerebrovascular disease. After embolization, craniotomy (or craniectomy) and intracerebral hemorrhage removal were performed in eight patients in-situ. Of the 40 frameless stereotactic procedure, 37 were extraventricular drainage before/after coil embolization in subarachnoid hemorrhage patients. They all mounted conduits in their planned locations. Conclusions: A hybrid OR for combined endovascular and surgical procedures represents a safe and useful strategy for cerebrovascular disease. In hybrid ORs various neurosurgical procedures can be safely and conveniently performed. Hybrid OR will pioneer a new era in neurosurgical procedures. [ABSTRACT FROM AUTHOR]

Primary closure of the surgical wound during neurosurgical procedures is sometimes difficult because of limited ability to expand the scalp, or because the skin defect is large. Hence, our institution recently adopted the technique of intraoperative tissue expansion using a Foley catheter for these cases. We describe this easily accomplished, readily available, effective, economical technique and describe our experience performing the technique. With this procedure, the subcutaneous tissue (usually the subperiosteal layer) surrounding the skin defect is dissected to make a subcutaneous pocket in which to place a 20-French Foley catheter. The standard expander is a 30-mL balloon. The catheter is inserted into the subcutaneous pocket, and the balloon is inflated with 10–30 mL of saline for 5 minutes, after which the balloon is deflated for 3 minutes in a cyclic loading manner. After sufficient expansion, the primary closure of the surgical wound is achieved with minimal tension on the surrounding skin. Between November 2018 and February 2020, we performed this technique in 5 patients, each with a large surgical defect in the scalp. Primary closure was achieved, and postoperative wound healing was excellent in all 5 patients. Intraoperative skin expansion using a Foley catheter—which is easily performed, readily available, and economical—can be used to achieve surgical wound closure during various neurosurgical procedures.

Background and Introduction: Donning and doffing of personal protective equipments (PPE) has become relevant especially during COVID-19 pandemic and neurosurgeons operating upon COVID-19 positive or suspect patients should be aware of proper technique of donning and doffing of PPE.[1] Surgeries involving direct exposure of anterior nasal spaces/paranasal sinuses carry significantly more risk of infection and it may be prudent to use PPE while operating all such cases.[2].Objective: In this video, we present our extensive protocol of donning and doffing of PPE which we have devised for our operating room.Technique: Donning consists of wearing of the PPE in a proper sequence so as to afford maximal protection from viral infection while conducting the surgical procedure. Various components of PPE and procedure of donning is shown followed by doffing, the sequential and safe removal of the PPE.Results: A meticulous method of donning and doffing PPE for neurosurgeons handling COVID-19 positive / suspect cases has been shown .Conclusion: Proper sequence of donning and doffing of PPE gear is of crucial importance during the COVID pandemic to prevent infection to the health care workers while handling COVID-19 positive/suspect cases and this video demonstrates the protocol we use at our institute.

Objective. Our objective was to determine the safety, efficacy, and surgical outcome of an extensive posterolateral approach for giant spinal epidural tumors. Materials and Methods. Our clinical study included 12 patients with various giant primary tumors and metastases of the spine, who underwent surgery between 2008 and 2019. The surgical procedure consisted of costotransversectomy, laminectomy, corpectomy, tumor resection, spinal column stabilization, and reconstruction. Neurological status examination and pain assessment were recorded at the time of admission, upon discharge and at outpatient check-up. Results. In our clinical sample, there were no major perioperative complications. All patients were discharged from the intensive care unit back to the hospital department within a week after the surgery. Postoperative follow-up showed no deterioration of neurological status. Furthermore, there was a moderate to significant improvement of paraparesis in all patients for weeks after surgery. The most notable improvement was significant pain relief in all the patients. None of the patients had issues with failure of the implanted hardware. Two patients died less than six months after the surgery due to the progression of the primary malignant process. Conclusion. An extensive posterolateral approach to giant spinal epidural tumors is an effective one-step approach. It presents a good compromise between invasiveness and sufficient exposure for both tumor resection and spinal column reconstruction. Good short-term clinical improvement can be achieved, but the long term results depend on the advancement of the initial disease. Careful evaluation and selection of patients are necessary to achieve clinical improvement and prolonged life expectancy, and the best results are achieved with a multidisciplinary approach.

Purpose The aim of this study was to investigate whether intraoperative ultrasonography (IOUS) helped the surgeon navigate towards the tumor as seen in preoperative magnetic resonance imaging and whether IOUS was able to distinguish between tumor margins and the surrounding tissue. Methods Twenty-five patients suffering from high-grade gliomas who were previously treated by surgery and radiotherapy were included. Intraoperatively, two histopathologic samples were obtained a sample of unequivocal tumor tissue (according to anatomical landmarks and the surgeon’s visual and tactile impressions) and a small tissue sample obtained using a navigated needle when the surgeon decided to stop the resection. This specimen was considered to be a boundary specimen, where no tumor tissue was apparent. The decision to take the second sample was not influenced by IOUS. The effect of IOUS was analyzed semi-quantitatively. Results All 25 samples of unequivocal tumor tissue were histopathologically classified as tumor tissue and were hyperechoic on IOUS. Of the boundary specimens, eight were hypoechoic. Only one harbored tumor tissue (P=0.150). Seventeen boundaries were moderately hyperechoic, and these samples contained all possible histological results (i.e., tumor, infiltration, or no tumor). Conclusion During surgery performed on relapsed, irradiated, high-grade gliomas, IOUS provided a reliable method of navigating towards the core of the tumor. At borders, it did not reliably distinguish between remnants or tumor-free tissue, but hypoechoic areas seldom contained tumor tissue.

Intracranial extension of frontal or ethmoid sinusitis carries a high morbidity and mortality if not treated aggressively. With the emergence of endoscopic sinus surgery (ESS), we questioned whether these approaches have supplanted traditional transcranial procedures for intracranial extension of sinus disease, and whether ESS approaches had a difference in patient outcomes. Studies reporting surgical management and outcomes of frontal sinus disease with intracranial extension were queried using the United States National Library of Medicine at the National Institutes of Health PubMed database. We also queried common internet search engines. We included studies regarding sinogenic intracranial suppurative infections treated surgically with ESS and neurosurgical approaches. Studies with insufficient data regarding specific treatment methods and studies that included populations of medically treated infections were excluded. A total of 108 cases were identified in which patients with intracranial sinogenic disease were treated via ESS alone (morbidity: 43.5%, mortality: 0.9%), 47 cases via transcranial intervention alone (morbidity: 33.2%, mortality: 7.8%), and 43 cases via simultaneous neurosurgical and ESS approaches (morbidity: 16.3%, mortality: 6.4%). Complex sinus disease with posterior table compromise in the absence of intracranial extension treated via ESS alone was reported in 164 cases with a morbidity and mortality of 3.8% and 0%, respectively. Combined ESS and transcranial approaches achieve definitive control of sinogenic and intracranial disease, whereas either modality alone carries a potential risk for higher morbidity and mortality. The use of ESS alone may have use in the treatment of sinusitis with posterior table erosion prior to intracranial extension. [ABSTRACT FROM AUTHOR]

Objective: Our goal was to highlight the prenatal diagnosis and management of central nervous system (CNS) anomalies through sharing our clinic's experience. Material and Methods: We evaluated prenatal findings and postnatal outcomes of neonates who had a CNS anomaly diagnosis in our clinic over a ten-year period. A total of 183 cases with various CNS anomalies were included in the study. Birth or termination preferences of mothers were recorded in all cases, and postnatal diagnosis concordance and prognosis after surgical procedures were evaluated in mothers who chose to continue the pregnancy. Results: The mean maternal age was 28.2±5.5 years, mean gravida was 2.2±1.3, and the mean gestational age at diagnosis was 30.5±5.5 weeks. Seventy-five out of 183 (41%) patients chose to terminate their pregnancy. Twenty babies (26.6%) in the termination of pregnancy group had additional anomalies. One hundred eight patients gave birth at our institution. The mean birth weight was 3060±647.5 g, the mean gestational week at delivery was 37.9±1.7 weeks, and mean APGAR score (5th minute) was 8.8±2.3. Four neonates died on the postpartum first day. The postnatal diagnosis of 60 of the 108 (55.5%) patients who gave birth was concordant with the prenatal diagnosis, and 32 of the 108 (29.6%) babies underwent surgical interventions. Conclusion: CNS anomalies have a broad spectrum and variable prognoses. This study highlights the limitations of prenatal diagnoses, and the need for parents to have this information in order to determine the course of their pregnancy and prepare themselves for the postnatal challenging treatment/rehabilitation process.

ABSTRACT We conducted a systematic review and meta-analysis of randomized and non-randomized controlled trials that compared pure endoscopic with microscopic transsphenoidal surgery (TSS) in the resection of pituitary tumors. Embase, PubMed, Lilacs, and Central Cochrane were used as our data sources. The outcomes were total tumor resection, achievement of biochemical control of functioning adenomas, hospital stay and surgery complications. The randomized trials were analyzed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. Two randomized and three prospective controlled non-randomized studies were included. Two studies, including 68 patients, evaluated total tumor resection and the meta-analysis did not show differences between the groups [RR: 1.45 (95% CI: 0.87, 2.44)]. Three studies involving 65 patients analyzed the achievement of biochemical control and no statistical difference was found [RR: 0.94 (95% CI: 0.7, 1.26)]. All five studies compared the frequency of postoperative complications between intervention and control group and meta-analysis favored for a low rate of postoperative complications in the endoscopic TSS group [(RR: 0.37 (95% CI: 0.16, 0.83)]. Due to the low evidence level and low number of observations, the results of our meta-analysis should not be viewed as a final proof of inferiority or superiority of one approach in relation to the other. More data including higher numbers of observations are needed.

Objective Increased attention has been paid to limiting preoperative hemostatic screening because assessment of patient history can be used as an alternative. However, there may be some clinical pitfalls in overlooking acquired coagulopathies. Here, we present a case of newly diagnosed acquired hemophilia A (AHA) that manifested as a massive intracranial hemorrhage without unexplained bleeding history or abnormal hemostatic results. Case Description A 58-year-old man, who had a history of surgical clipping of an anterior communicating artery aneurysm 30 years ago, experienced subarachnoid hemorrhage because of a ruptured middle cerebral artery aneurysm. He underwent surgical clipping and external decompressive craniectomy; 30 days later, cranioplasty was performed without preoperative hemostatic screening because of his normal coagulation status at the time of a previous surgery. Persistent wound bleeding and epistaxis suddenly began 6 hours after surgery. Computed tomography (CT) revealed a massive intracranial hematoma in the damaged parenchyma, although the patient was asymptomatic. At that time, laboratory tests showed isolated prolonged activated partial thromboplastin time and the presence of factor VIII inhibitor, which confirmed AHA. To manage the bleeding, fresh frozen plasma was transfused for 4 consecutive days, and hemostasis was finally achieved. Thereafter, the laboratory test results were normalized in 5 weeks. The patient's clinical course has been uneventful for 7 months without recurrence of AHA. Conclusions Acquired coagulopathies are relatively rare but life-threatening. Because clinical history is insufficient to predict an acquired coagulopathy, preoperative hemostatic screening should be performed before each neurosurgical procedure. [ABSTRACT FROM AUTHOR]

Introduction: The spinal cord stimulation (SCS) has been described as a valuable neuromodulating procedure in the management of chronic and medically untreated neuropathic pain. Although, many studies have discussed the use of this technique, a question still remains regarding its efficacy in different medical conditions with different etiology in the long term. The aim of this paper is to discuss the risks, complications, cost-effectiveness and results of SCS in patients affected by chronic neuropathic pain based on the comprehensive literature review. Methods: Bibliographic search of references from 1950 to 2016 using the databases MEDLINE, LILACS, SciELO, PubMed, and applied language as selection criteria, choosing preferably recent articles written in Portuguese, Spanish or English. Results: Based on literature review, SCS is a safe, reversible, adjustable and nondestructive surgical procedure demonstrating a significant effect in the reduction of pain intensity and improvement in quality of life in these patients. Furthermore, in spite of the initial high cost to its application, SCS has been associated with lower rates of complications and high rates of cost-effectiveness when compared to standard therapies. Conclusion: Although used in medical conditions with different etiology, the procedure is still an effective and a cost-effective approach to neuropathic pain, mainly in patients affected by failed back pain syndrome (FBSS) and complex regional pain syndrome (CRPS).

Background Gross total resection for malignant brain neoplasms is challenging owing to the heterogeneity of these lesions and infiltration in eloquent areas. Gross total resection is a very important part of treatment of these patients and is a crucial prognostic factor. Fluorescence-guided surgery is an important tool that improves the rate of total resection. Methods We built a device to use in surgical microscopes with an excitation and a barrier filter to perform fluorescence-guided surgery. All patients received a standard dose of 500 mg of sodium fluorescein before skin incision. Surgical view under white light was compared with use of the light filters. Results In all cases with use of the filters, the tumors showed a high fluorescence contrasting with the normal surrounding brain, making it easier to identify the limits of the lesion and to achieve gross total resection. Conclusions The use of fluorescence for malignant brain tumor resection increases the rate of gross total resection. It is an important tool that makes it possible to identify the lesion in areas where it looks like normal tissue under white light. This device is a low-cost option that has shown good results in our experience. [ABSTRACT FROM AUTHOR]

Objective To investigate the three neurosurgical procedures for the hypertensive basal ganglia hemorrhage and select a proper surgical treatment for individual. Methods The clinical data of 457 patents with hypertensive basal ganglia hemorrhage from January 2007 to November 2015, treated by neurosurgical procedures, were reviewed retrospectively. The comparison of intracranial pressure, occurrence of complications and neurological outcome in the three groups who were treated by conventional open craniotomy (COC), small craniotomy (SC) and skull puncture and drainage (SPD) were performed. Results The values of intracranial pressure were lower in the group of COC than that of SC after 24 hours post operation. The incidence of pulmonary infection, incision of tracheal and abdominal distension in the group of COC was lower than that of SC and SPD. And there were no difference between the three groups in the incidence of alimentary tract hemorrhage. Moreover, the incidence of postoperative re-bleeding and mortality were higher in SPD group, in comparison with COC and SC group. There was no significant difference in mortality between the COC and SC groups. The well rate in the COC group is better than that of SC group and SPD group. Conclusion Different neurosurgical procedures have different indications. The neurosurgery through the individualized approach and microneurosurgical technique may decrease the complications and mortality and improve prognosis in the patient with hypertensive basal ganglia hemorrhage.

Introduction: The spinal cord stimulation (SCS) has been described as a valuable neuromodulating procedure in the management of chronic and medically untreated neuropathic pain. Although many studies have discussed the use of this technique, a question still remains regarding its efficacy in different medical conditions with different etiology in the long term. The aim of this paper is to discuss the risks, complications, cost-effectiveness, and results of SCS in patients affected by chronic neuropathic pain based on the comprehensive literature review. Methods: Bibliographic search of references from 1950 to 2016 using the databases MEDLINE, LILACS, SciELO, PubMed, and applied language as selection criteria, choosing preferably recent articles written in Portuguese, Spanish, or English. Results: Based on literature review, SCS is a safe, reversible, adjustable, and non-destructive surgical procedure demonstrating a significant effect in the reduction of pain intensity and improvement in the quality of life in these patients. Furthermore, in spite of the initial high cost to its application, SCS has been associated with lower rates of complications and high rates of cost-effectiveness when compared to standard therapies. Conclusion: Although used in medical conditions with different etiology, the procedure is still an effective and a cost-effective approach to neuropathic pain, mainly in patients affected by Failed Back Surgery Syndrome (FBSS) and complex regional pain syndrome.

Purpose: The aim of this study was to investigate whether intraoperative ultrasonography (IOUS) helped the surgeon navigate towards the tumor as seen in preoperative magnetic resonance imaging and whether IOUS was able to distinguish between tumor margins and the surrounding tissue. Methods: Twenty-five patients suffering from high-grade gliomas who were previously treated by surgery and radiotherapy were included. Intraoperatively, two histopathologic samples were obtained a sample of unequivocal tumor tissue (according to anatomical landmarks and the surgeon's visual and tactile impressions) and a small tissue sample obtained using a navigated needle when the surgeon decided to stop the resection. This specimen was considered to be a boundary specimen, where no tumor tissue was apparent. The decision to take the second sample was not influenced by IOUS. The effect of IOUS was analyzed semi-quantitatively. Results: All 25 samples of unequivocal tumor tissue were histopathologically classified as tumor tissue and were hyperechoic on IOUS. Of the boundary specimens, eight were hypoechoic. Only one harbored tumor tissue (P=0.150). Seventeen boundaries were moderately hyperechoic, and these samples contained all possible histological results (i.e., tumor, infiltration, or no tumor). Conclusion: During surgery performed on relapsed, irradiated, high-grade gliomas, IOUS provided a reliable method of navigating towards the core of the tumor. At borders, it did not reliably distinguish between remnants or tumor-free tissue, but hypoechoic areas seldom contained tumor tissue. [ABSTRACT FROM AUTHOR]

The purpose of the study was to identify the adequacy of enteral feeding, and the reason and prevalence of under-nutrition, and to determine the relationships between caloric intake and resulting nutritional parameters among neurosurgical intensive care unit (ICU) patients. Methods: The participants for this descriptive study were 47 neurosurgical ICU patients who had enteral feeding initiated after ICU admission. Data were collected from the initial day of enteral feeding for 7 days. Data related to enteral feeding, feeding interruptions or delay, prealbumin, and transferrin were collected. Results: The mean age of the participants was 56.62 years. Twenty-six patients did not receive their feeding formula more than once during 7 days, and 11 had interruptions more than 6 times. The mean number of feeding interruptions was 3.23 (SD = 4.47). On the average, only 76.44% of the estimated energy requirement was provided by enteral feeding to the patients. The frequency of underfeeding was 52.17% with respect to enteral feeding. The most frequent reason for the feeding interruption was observation before and after intubation and extubation, which was unavoidable. The next most common reason was gastrointestinal bleeding, mostly due to old clots or trace, followed by residual volume less than 100 mL. Changes in prealbumin and transferrin levels for 7 days between the underfed and adequately fed groups were not statistically significant. Conclusion: The management of enteral feeding by nurses was overprotective because of the unpredictable nature of ICU patients in terms of their underlying disease process. The management of feeding intolerance needs to be evidence-based and nurses must consistently follow the protocol that has been supported as a useful measure.

Background Post-craniotomy headache is a frequent complication of neurosurgical procedures and is often a challenge for neurosurgeons, neurologists, and headache specialists. Method This was a narrative review. Results Surgical trauma, adherence of the musculature to the dura mater, peripheral nerve injury, development of neurinomas in the surgical scar, and central sensitization may be involved in the genesis of such headaches. Performing smaller craniotomies, replacement of the bone (craniotomy), performing cranioplasty, and infiltration of the surgical site with local anesthesia at the end of the surgical procedure are strategies used to prevent such headaches. Among the most frequent characteristics of post-craniotomy headaches are that they start on the first days after the operation, are located on the same side as and at the site of the surgical scar, and improve with the passage of time. Depression, anxiety, and temporomandibular disorders are frequently associated with these headaches. Abortive treatment such as opioids, ordinary analgesics, non-hormonal anti-inflammatory drugs, and triptans can be administered. There have been reports of improvements using sodium divalproex, verapamil, and local anesthetics. Conclusions Post-craniotomy headaches can have significant repercussions on patients' quality of life. There is a need for clinical trials evaluating therapeutic options for treatment of this type of headache. [ABSTRACT FROM AUTHOR]

An orphan female chimpanzee was wounded by a left craniocerebral gunshot complicated with a right hemiparesis. Local treatment and long-term antibiotherapy failed to lead to healing. A neurosurgical procedure was planned and achieved. She fully recovered, and 2 years after the procedure, there is no evidence of infection. [ABSTRACT FROM AUTHOR]

Coil migration into the parent artery during endovascular coil embolization is a rare, but life-threatening complication, which can induce thromboembolism and result in poor outcome. A 63-year-old man was referred to Chonbuk National University Hospital emergency center due to migration of a coil for a left middle cerebral artery bifurcation unruptured aneurysm. We performed an emergency craniectomy to remove the coil migrated to the distal M2 branch and thrombus, and aneurysmal neck clipping for his aneurysm. Fortunately, at the six month follow-up, the patient did not show any noticeable neurological sequela. In case of parent artery occlusion due to coil migration an immediate recanalization should be performed by a neurovascular specialist who can provide both surgical treatment and endovascular management in order to prevent severe sequela or even death.

Background Development of the flexible CO2 fiber has presented new opportunities for the use of precision laser cutting in cranial procedures. The efficacy of the CO2 scalpel is further enhanced by combining it with a fluid removal suction capability. Objectives We report our experience with a novel CO2 laser-suction device. Methods The novel laser-suction device was designed in conjunction with OmniGuide Inc. (Cambridge, Massachusetts, USA). We performed a case review of its use in firm tumors that were resistant to resection by bipolar, suction, and ultrasonic aspirator. Results The laser-suction device was applied in three tumors where resection with ultrasonic aspiration failed. Tumor resection using the laser-suction device was successful in all three cases. There were no complications related to the laser-suction device. There were no instances of intraoperative device malfunction. Discussion The CO2 laser combined with suction is a useful instrument for resection of firm tumors that prove to be resistant to ultrasonic aspiration. We also find it to be useful in settings where precise tissue incisions are desired with minimal manipulation. In our experience, the surgical efficiency of the CO2 laser is improved by the laser-suction device. This device allows the surgeon to utilize a suction device and laser in a single hand and enables concurrent use of bipolar electrocautery without repeated instrument changes. [ABSTRACT FROM AUTHOR]

Endoscopic techniques are increasingly being used in recent times for various spinal and brain pathologies. Although endoscopic neurosurgical technique holds the potential for reducing morbidity, it is also associated with limitations such as steep learning curve, obstruction in manipulation of instruments by telescope in an already limited exposure, proximal blind spot, visual obscuration, disorientation, loss of stereoscopic image and others. Neuroendoscopy is distinct from micro-surgery and a thorough understanding of the technique and its limitations is required to get maximal benefit. Difficulties in controlling bleeding, longer operative time are common obstacles with this technique, especially in early learning curve. Higher complication rate during initial learning curve can be reduced by attending live workshops, practice on models and hands on cadaveric workshops. Large vascular lesions should be avoided and a thorough knowledge of possible complications and techniques to avoid such complications can improve results in endoscopic surgery .

Invasive aspergillosis is a serious infectious complication, which can occur after hematopoietic stem cell transplantation (HSCT). In particular, despite antifungal treatment, invasive aspergillosis involving the central nervous system (CNS) shows very high mortality. In principle, a neurosurgical procedure with an antifungal agent is recommended for treatment of CNS invasive aspergillosis. We encountered a patient suffering from disseminated invasive aspergillosis involving the lung, brain, and soft tissues after allogeneic HSCT for treatment of relapsed acute myeloid leukemia who was cured with voriconazole and stereotactic drainage of the brain abscess.

Introduction: Multidrug-resistant strains of Acinetobacter pose a serious therapeutic dilemma in hospital practice, particularly when they cause meningitis, as the few antimicrobial agents to which these isolates are susceptible have poor central nervous system (CNS) penetration. Methodology: We retrospectively reviewed the clinical course and outcome of eight consecutive cases of meningitis due to Acinetobacter spp. in children ages 15 years or less, seen in a tertiary care medical center in Karachi, Pakistan. Results: Of the eight cases of Acinetobacter meningitis, isolates from five patients were pan-resistant, and two were multidrug-resistant. A neurosurgical procedure was performed in five of eight patients followed by external ventricular drain insertion prior to the development of infection. Seven received intravenous (IV) polymyxin (mean; 12.8 days), while 5/8 also received intrathecal (IT) polymyxin (mean; 12.0 days). The mean length of hospitalization was 38.7 ± 19 days. All patients achieved cerebrospinal fluid (CSF) culture negativity by the end of treatment (mean; 5.4 days). Two patients died: one with pan-resistant Acinetobacter, and the second with a multi-drug resistant isolate. Conclusion: Post-neurosurgical multidrug-resistant and pan-resistant Acinetobacter meningitis can be successfully treated if appropriate antimicrobial therapy is instituted early. The role of IT polymyxin B administration alone versus combination therapy (IV and IT) needs further study. [ABSTRACT FROM AUTHOR]

Background: The retromastoid approach has been effective in exposing the cerebellopontine angle for resection of a variety of lesions, including vestibular schwannomas and decompression of cranial nerves. The following incisions and their variations have been most commonly used for the retromastoid approach: linear (and its variations, such as “lazy S-shaped”) and “C-shaped” incision. Methods: Herein, we describe a curvilinear incision and compare its advantages and disadvantages with the other previously described incisions based on the senior author’s experience with 120 retromastoid operations. Results: The senior author has used the curvilinear incision for the last 70 of 120 patients who underwent retromastoid operations. Of these, one patient encountered postoperative cerebrospinal fluid (CSF) leakage through the incision, requiring a repeat operative wound revision, and one patient suffered from a soft asymptomatic pseudomeningocele. Among the initial 50 patients who underwent a linear incision, one patient suffered from a CSF leakage managed with local wound care and another patient required a repeat operation for a tense pseudomeningocele. No wound breakdown or infection was encountered in either group. Conclusions: The curvilinear incision is simple and efficient and may provide a shorter working distance and protect the suboccipital muscles and associated neurovascular bundle.

Background/Aim: To assess the feasibility of post-mortem surveillance for subclinical variant Creutzfeldt-Jakob disease (vCJD) at least 5 years after neurosurgical procedures. Methods: Using Scottish record linkage, we estimated 5-year survival and re-operation rates after 4 neurosurgical procedures performed during 1993–2001 and identified as high or medium risk for transmitting vCJD: [B] drainage of extra- or subdural haematoma, [E] primary or revisional decompression operations and [H] creation of other ventricular shunts were classified as high risk; [C] operations on cerebral aneurysm (clipping) were classified as medium risk. Results: Fatality rate at 1 year depended strongly on procedure, weakly or not at all on sex and era, and increased with age. Procedure rates differed by sex. The rate of subsequent neurosurgical operations was highest for procedure [H] (sole: 21%; multiple: 28%). Conclusion: Each year, the UK has a new cohort of some 5,000 5-year survivors after a high- or medium-risk neurosurgical procedure, whose subsequent annual mortality is at least 3%. Even if half the surviving 5-year survivors of neurosurgery since 1996 gave consent-in-life for vCJD-informative testing at post-mortem, there would be too few relevant post-mortems in 2008–2010 (around 1,600) for ‘nil detections’ to exclude a 1 in 1,000 subclinical vCJD rate. Autopsy surveillance beyond 2010, or among 5-year survivors of non-neurosurgical at-risk operations, would be needed. Copyright © 2009 S. Karger AG, Basel [ABSTRACT FROM AUTHOR]

Abstract: Neurogenic bladder caused by SCI or spina bifida is a major problem. Research in restoring functional micturition has mainly focused on electrical stimulation for many decades with good progress, but it is still not the definitive solution for majority of the SCI patients. An alternative approach has been to investigate restoring innervation to the lower urinary tract after spinal SCI. Different animal and clinical studies were reviewed historically in this article, focused on mainly cross over nerve surgery for reinnervation of the bladder. An artificial somatic-autonomic reflex pathway procedure and its mechanisms were introduced. Clinical application and the satisfactory results of the new procedure were reviewed in details in restoring voluntary bladder control in patients with SCI or spina bifida. [Copyright &y& Elsevier]

Background. Aneurysmal bone cyst (ABC) is a benign, expansive, osteolytic lesion that mainly occurs in young people, and involves the skull bones only exceptionally. The origin of ABC is controversial: secondary reactive bone lesion, or primary disease that represents an independent nosological entity. Blunt head trauma was suggested as a possible etiological factor. Case report. A case of a 19-year-old man with primary ABC of the right frontal bone was reported. The lesion was totally excised through frontal craniotomy, and the skull bone defect primarily reconstructed with an acrilate cranioplasty. Five years after the surgery, the patient was without signs of local recurrence. Conclusion. Clinical and neuroradiological presentation of the skull ABC was not specific. Pathohistology confirmed the diagnosis. Total excision was the treatment of choice. [ABSTRACT FROM AUTHOR]

Abstract: Background:: We assess that pudendal neuralgia is a tunnel syndrome due to a ligamentous entrapment of the pudendal nerve and have treated 400 patients surgically since 1987. We have had no major complication. We conducted a randomized controlled trial to evaluate our procedure. Methods:: A sequential, randomized controlled trial to compare decompression of the pudendal nerve with non-surgical treatment. Patients aged 18–70, had chronic, uni/bilateral perineal pain, positive temporary response to blocks at the ischial spine and in Alcock''s canal. They were randomly assigned to surgery (n =16) and control (n =16) groups. Primary end point was improvement at 3 months following surgery or assignment to the non-surgery group. Secondary end points were improvement at 12 months and at 4 years following surgical intervention. Results:: A significantly higher proportion of the surgery group was improved at 3 months. On intention-to-treat analysis 50% of the surgery group reported improvement in pain at 3 months versus 6.2% of the non-surgery group (p =.0155); in the analysis by treatment protocol the figures were 57.1% versus 6.7% (p =.0052). At 12 months, 71.4% of the surgery group compared with 13.3% of the non-surgery group were improved, analyzing by treatment protocol (p =.0025). Only those randomized to surgery were evaluated at 4 years: 8 remained improved at 4 years. No complications were encountered. Conclusions:: In this study we demonstrate that decompression of the pudendal nerve is an effective and safe treatment for cases of chronic pudendal neuralgia that have been unresponsive to analgesia and nerve blocks. Following surgery, other medical interventions may be necessary. [Copyright &y& Elsevier]

We report four cases of nosocomial E. coli meningitis, in male patients with accidental and neurosurgical trauma. The interval between accidents/neurosurgical procedures and the onset of meningitis was 2-15 days (mean 6.25 days). The most consistent clinical features were fever and deterioration of consciousness level. Emergence of extended spectrum beta lactamase E. coli strains had been observed in two (50%) of our cases and the mean duration of antimicrobial treatment was 16.5 days (range: 6-24 days). Two of the four patients (50%) died in the hospital. [ABSTRACT FROM AUTHOR]

Objective: The aim of the study is to define the topographical evaluation and the shape of foramen spinosum (FS) on skulls and to obtain the distances between the structure and related anatomical bony landmarks. Methods: The study was performed on the craniums of 50 (100 sides) West Anatolian adult subjects. Morphometric measurements of the FS and related adjacent structures were taken of the skulls using a Vernier caliper accurate 0.01 mm. The results were evaluated statistically with SPSS 22.0. Results: The mean distance of the right FS and the left FS; the distance between FS and the structures such as foramen rotundum, foramen ovale, and the distance between FS and foramen ovale were investigated. The mean distance between the foramen and posterior, middle and anterior clinoid processes were also evaluated, respectively. The mean distance between the foramen and lateral border of sella turcica were also evaluated, respectively. Evaluations have already been carried on. Conclusion: Anatomical results of FS and related anatomical bony landmarks may be useful for neurosurgical procedure. [ABSTRACT FROM AUTHOR]

Objective: The aim of this study is to determine the localization, mean length, mean diameter and also the shape of the superior orbital fissure (SOF) on skulls and to find out the distances between the structure and neighbouring anatomical bony landmarks. We also applied stereological assessment method for estimating the surface area of SOF. Methods: This study was performed on the craniums of 50 (100 sides) West Anatolian adult subjects. Morphometric measurements of the SOF were taken from the skulls using a Vernier caliper accurate 0.01 mm. A uniform point-grid with a point associated area of 0.25 cm2 was randomly superimposed on each SOF of dry skull. The results were evaluated statistically with SPSS 22.0. Results: Distance between SOF and foramen lacerum; the distance between SOF and foramen spinosum and distance between SOF and the neigbourhood structures such as foramen rotundum, foramen ovale were evaluated. Evaluations have already been carried on. Conclusion: The localization of the fissure, the mean lenght and the mean diameter of SOF and the distances between the fissure and anatomical bony landmarks are of importance during neurosurgical interventions.

Objective: The aim of this study is to determine the localization and the shape of foramen lacerum (FL) on skulls and to find out the distances between the area and neigbouring anatomical bony landmarks. Methods: The study was performed on the craniums of 50 (100 sides) West Anatolian adult subjects. Morphometrical measurements of the FL and related adjacent structures were taken of the skulls using a Vernier caliper accurate 0.01 mm. The results were evaluated statistically with SPSS 22.0. Results: The distance of the right FL and the left FL, the distance between FL and the structures such as the carotid canal, hiatus for lesser petrosal nerve, foramen ovale, foramen spinosum, foramen rotundum and the distance of both the right and left FL to midline were evaluated. The distance of FL and posterior, middle and anterior clinoid processes were also evaluated on both side, respectively. Evaluations have already been carried on. Conclusion: The localization of FL and the distances between the foramen and the anatomical bony landmarks may be useful for neurosurgical approach. [ABSTRACT FROM AUTHOR]

Objective Commercially available fibrin glue (Com-FG), which is used commonly worldwide, is produced with pooled human plasma from multiple donors. However, it has added bovine aprotinin, which involves the risk of infection, allogenic immunity, and allergic reactions. We evaluate the efficacy, reliability, and safety of completely autologous fibrin glue (CAFG). Methods From August 2014 to February 2016, prospective data were collected and analyzed from 153 patients. CAFG was prepared with the CryoSeal System using autologous blood and was applied during neurosurgical procedures. Using CAFG-soaked oxidized regenerated cellulose and/or polyglycolic acid sheets, we performed a pinpoint hemostasis, transposed the offending vessels in a microvascular decompression, and covered the dural incision to prevent cerebrospinal fluid leakage. Results The CryoSeal System had generated up to a mean of 4.51 mL (range, 3.0–8.4 mL) of CAFG from 400 mL autologous blood. Com-FG products were not used in our procedures. Only 6 patients required an additional allogeneic blood transfusion. The hemostatic effective rate was 96.1% (147 of 153 patients). Only 1 patient who received transsphenoidal surgery for a pituitary adenoma presented with the complication of delayed postoperative cerebrospinal fluid leakage (0.65%). No patient developed allergic reactions or systemic complications associated with the use of CAFG. Conclusions CAFG effectively provides hemostatic, adhesive, and safety performance. The timing and three-dimensional shape of CAFG-soaked oxidized regenerated cellulose and/or polyglycolic acid sheets solidification can be controlled with slow fibrin formation. The cost to prepare CAFG is similar compared with Com-FG products, and it can therefore be easily used at most institutions. [ABSTRACT FROM AUTHOR]
