OBJECTIVES: To determine the treatment effect of corticosteroids in periradicular therapy (PRT) for radicular pain and to compare different types of corticosteroids and ozone. We also examined the effect in different indication groups for periradicular therapy for each type of treatment agent. BACKGROUND: Various studies have examined the therapeutic value of periradicular infiltration using treatment agents consisting of local anesthetic and corticosteroids or ozone application for radicular pain. This is the first study to compare different types of corticosteroids and ozone. METHODS: Eligible patients with radicular pain who failed conservative management were divided into five indication groups and prospectively followed to assess the PRT effect of corticosteroids or ozone application. PRT was performed under computer tomography (CT) monitoring. A set of three PRT applications in three weeks was applied and the outcome was evaluated using a visual analogue score for back and leg pain. The in-group and between-group treatment effect was tested using the Wilcoxon signed-rank test and the Kruskal-Wallis H-test with Dunn's post-hoc tests, respectively. The dependency between treatment effectiveness and indication for each group was tested using the Kruskal-Wallis H-test and Dunn's post-hoc tests. RESULTS: We prospectively followed 150 patients, randomized into three groups of 50 patients each. The follow-up rate was 100%. All three treatment agents showed a statistically significant treatment effect (P<0.001). The statistically significant effect was higher in betamethasone (Diprophos) versus methylprednisolone (Depomedrone) (P=0.019) and Diprophos versus ozone (P<0.001). Diprophos also showed the highest decrease of VAS after therapy versus VAS prior to therapy (median decrease = 4) compared to Depomedrone and ozone (median decrease = 3 and 2, respectively). The statistically significant outcome was better with the indication of spondylolisthesis and disc herniation (P=0.019) indication for the Diprophos group and between spinal stenosis and spondylolisthesis (P=0.022) and spondylolisthesis and disc herniation (P=0.016) for the ozone group. CONCLUSION: Clinical improvement occurred in all three groups but Diprophos showed the statistically best treatment effect compared to Depomedrone and ozone. Disc herniation resulting in radicular pain had a statistically significant better effect in comparison with spondylolisthesis in the Diprophos and ozone groups, but the ozone group showed heterogeneity depending on treatment effect and indication.

Úvod: Dekompresivní kraniektomie (DK) je život zachraňující neurochirurgický výkon s několika technickými možnostmi provedení. Cíl: Cílem této studie bylo porovnat výsledky operační techniky DK s duroplastikou a bez provedené duroplastiky na dvou neurochirurgických pracovištích. Metodika: Retrospektivní bicentrická studie hodnotila výskyt komplikací (tj. infekční, likvorová píštěl, hematom) u jednotlivých technik. Výsledky: Ve studii nebyl prokázán statisticky signifikantně vyšší výskyt komplikací jako jsou infekce (p = 0,539), likvorová píštěl (p = 0,826) či hematom (p = 0,720). V obou sledovaných souborech po kranioplastice nebyly zaznamenány infekční komplikace nebo likvorová píštěl. Komplikace ve formě hematomu byla statisticky nevýznamná (p = 0,155). Byl zjištěn statisticky významný rozdíl v operačním čase kranioplastiky provedené po DK s duroplastikou (medián 53 min) a po DK bez provedené duroplastiky (medián 90 min; p = 0,006). Závěr: DK bez provedení duroplastiky je potenciální bezpečná varianta, která není zatížená vyšším výskytem komplikací ve smyslu infekce nebo vzniku likvorové píštěle a hematomu.
Background: Decompressive craniectomy (DC) is a life-saving neurosurgical procedure with several technical options. Aim: The aim of this study was to compare the results of the DC surgical technique with and without duroplasty performed at two neurosurgery departments. Methods: A retrospective bicentric study evaluated the occurrence of complications (i.e., infection, cerebrospinal fluid fistula, hematoma) in both compared techniques. Results: The study did not demonstrate a statistically significantly higher incidence of complications such as infection (P = 0.539), cerebrospinal fluid fistula (P = 0.826) or hematoma (P = 0.720). No infectious complications or cerebrospinal fluid fistula were recorded in both observed groups after cranioplasty. The complication in the form of hematoma was statistically insignificant (P = 0.155). A statistically significant difference was found in the operative time of cranioplasty performed after DC with duroplasty (median 53 min) and after DC without duroplasty (median 90 min; P = 0.006). Conclusion: DC without duroplasty is a potentially safe option that is not burdened by a higher incidence of complications in terms of infection or the formation of cerebrospinal fluid fistula and hematoma.

Reflecting the first wave COVID-19 pandemic in Central Europe (i.e. March 16th-April 15th, 2020) the neurosurgical community witnessed a general diminution in the incidence of emergency neurosurgical cases, which was impelled by a reduced number of traumatic brain injuries (TBI), spine conditions, and chronic subdural hematomas (CSDH). This appeared to be associated with restrictions imposed on mobility within countries but also to possible delayed patient introduction and interdisciplinary medical counseling. In response to one year of COVID-19 experience, also mapping the third wave of COVID-19 in 2021 (i.e. March 16 to April 15, 2021), we aimed to reevaluate the current prevalence and outcomes for emergency non-elective neurosurgical cases in COVID-19-negative patients across Austria and the Czech Republic. The primary analysis was focused on incidence and 30-day mortality in emergency neurosurgical cases compared to four preceding years (2017-2020). A total of 5077 neurosurgical emergency cases were reviewed. The year 2021 compared to the years 2017-2019 was not significantly related to any increased odds of 30 day mortality in Austria or in the Czech Republic. Recently, there was a significant propensity toward increased incidence rates of emergency non-elective neurosurgical cases during the third COVID-19 pandemic wave in Austria, driven by their lower incidence during the first COVID-19 wave in 2020. Selected neurosurgical conditions commonly associated with traumatic etiologies including TBI, and CSDH roughly reverted to similar incidence rates from the previous non-COVID-19 years. Further resisting the major deleterious effects of the continuing COVID-19 pandemic, it is edifying to notice that the neurosurgical community ́s demeanor to the recent third pandemic culmination keeps the very high standards of non-elective neurosurgical care alongside with low periprocedural morbidity. This also reflects the current state of health care quality in the Czech Republic and Austria.

BACKGROUND: Transsphenoid meningoencephalocele is a congenital anomaly formed by herniation of an ependyma delimited sac through a bony defect into the sphenoid sinus. The sac contains cerebrospinal fluid and neurovascular structures. The prevalence of transsphenoid meningoencephalocele in the adult population is rare. It usually manifests as nasal liquorrhoea. METHODS AND RESULTS: This case report presents an adult male who underwent surgery due to suspected pituitary macroadenoma. The surgery was performed endoscopically via the transnasal approach with a surprising finding of true transsphenoid meningoencephalocele. Ectopic solid tissue was found in the sphenoid sinus in which pituitary adenoma was histologically confirmed. CONCLUSION: This paper presents a previously unpublished combination of true transsphenoid meningoencephalocele and pituitary adenoma in an adult individual.

The world currently faces the novel severe acute respiratory syndrome coronavirus 2 pandemic. Little is known about the effects of a pandemic on non-elective neurosurgical practices, which have continued under modified conditions to reduce the spread of COVID-19. This knowledge might be critical for the ongoing second coronavirus wave and potential restrictions on health care. We aimed to determine the incidence and 30-day mortality rate of various non-elective neurosurgical procedures during the COVID-19 pandemic. A retrospective, multi-centre observational cohort study among neurosurgical centres within Austria, the Czech Republic, and Switzerland was performed. Incidence of neurosurgical emergencies and related 30-day mortality rates were determined for a period reflecting the peak pandemic of the first wave in all participating countries (i.e. March 16th-April 15th, 2020), and compared to the same period in prior years (2017, 2018, and 2019). A total of 4,752 emergency neurosurgical cases were reviewed over a 4-year period. In 2020, during the COVID-19 pandemic, there was a general decline in the incidence of non-elective neurosurgical cases, which was driven by a reduced number of traumatic brain injuries, spine conditions, and chronic subdural hematomas. Thirty-day mortality did not significantly increase overall or for any of the conditions examined during the peak of the pandemic. The neurosurgical community in these three European countries observed a decrease in the incidence of some neurosurgical emergencies with 30-day mortality rates comparable to previous years (2017-2019). Lower incidence of neurosurgical cases is likely related to restrictions placed on mobility within countries, but may also involve delayed patient presentation.

OBJECT: Deep brain stimulation (DBS) is a very useful procedure for the treatment of idiopathic Parkinson's disease (PD), essential tremor, and dystonia. The authors evaluated the accuracy of the new method used in their center for the placing of DBS electrodes. Electrodes are placed using the intraoperative O-armTM (Medtronic)-controlled frameless and fiducial-less system, NexframeTM (Medtronic). Accuracy was evaluated prospectively in eleven consecutive PD patients (22 electrodes). METHODS: Eleven adult patients with PD were implanted using the Nexframe system without fiducials and with the intraoperative O-arm (Medtronic) system and StealthStationTM S8 navigation (Medtronic). The implantation of DBS leads was performed using multiple-cell microelectrode recording, and intraoperative test stimulation to determine thresholds for stimulation-induced adverse effects. The accuracy was checked in three different steps: (1) using the intraoperative O-arm image and its fusion with preoperative planning, (2) using multiple-cell microelectrode recording and counting the number of microelectrodes with the signal of the subthalamic nucleus (STN) and finally, (3) total error was calculated according to a postoperative CT control image fused to preoperative planning. RESULTS: The total error of the procedure was 1.79 mm; the radial error and the vector error were 171 mm and 163 mm. CONCLUSIONS: Implantation of DBS electrodes using an O-arm navigated frameless and fiducial-less system is a very useful and technically feasible procedure with excellent patient toleration with experienced Nexframe users. The accuracy of the method was confirmed at all three steps, and it is comparable to other published results.

PURPOSE OF THE STUDY Minimally invasive posterior lumbar interbody fusion and percutaneous instrumentation were introduced in the clinical practice with the aim to reduce the damage to musculoligamentous structures associated with open surgeries. The purpose of the study is to evaluate the clinical outcomes, radiological results and complications of the group of patients operated with the use of the minimally invasive posterior lumbar interbody fusion technique. MATERIAL AND METHODS The group of 31 patients operated for lumbar degenerative disc disease was followed-up prospectively. The surgical technique included a unilateral microsurgical decompression of the spinal canal with the insertion of interbody cages supplemented by percutaneous transpedicular fixation. The clinical outcomes were evaluated by means of the Oswestry Disability Index (ODI), Macnab classification, VAS score for low back pain (VAS LBP) and lower extremity pain (VAS LE) at 2, 6, 12 and 24 months postoperatively. The success rate of interbody fusion and complications was also assessed. RESULTS The inclusion criteria were met by 29 patients. The mean preoperative ODI score of 68.4 decreased to 25.1 at two-year follow-up (p 0.001). Based on the modified Macnab scale excellent and good outcomes were achieved at two-year-followup by 82.4% patients. The mean value of VAS LBP score decreased from 6.2 to 2.1 and in case of VAS LE from 5.38 to 1.34 (p ˂ 0.001). The mean time of operation was 157 minutes. Solid interbody fusion was achieved in 80% of patients. In one case, revision surgery for dislocation of the interbody cage was performed one year after the operation. A total of five misplaced transpedicular screws (5.2%) were recorded. DISCUSSION Dorsal minimally invasive spinal operational techniques, when compared with the open surgery, result in less iatrogenic injury to paravertebral muscles. From a short-term perspective, there is also less blood loss and lower frequency of infectious complications. Together with the reduction of postoperative pain and shorter hospital stay, they enable faster recovery and rehabilitation with comparable clinical effectiveness of the procedure. Apart from the above-mentioned benefits, also some shortcomings are discussed such as higher frequency of complications, longer time of operation, higher occurrence of implant malposition and higher exposure of the patient and the surgeon to radiation. CONCLUSIONS The minimally invasive posterior lumbar interbody fusion technique resulted in a statistically significant clinical improvement in the ODI, Macnab scale, VAS LBP and VAS LE scores. The percutaneous instrumentation technique shows an acceptable rate of incorrectly inserted screws. Key words: degenerative disc disease, minimally invasive spinal surgery, posterior lumbar interbody fusion, spine stabilization, lumbar interbody fusion complications.
