Compared with conventional MRI, pMRI is less resource-intensive with regard to operational costs and scan time. The application of pMRI in neurosurgical oncology has not been previously described. The goal of this study was to demonstrate the efficacy of pMRI in assessing optic nerve decompression after endoscopic endonasal surgery for sellar and suprasellar pathologies.METHODS Patients who underwent endoscopic endonasal surgery for sellar and suprasellar lesions at a single institution and for whom pMRI and routine MRI were performed postoperatively were retrospectively reviewed to compare the two imaging systems. To assess the relative resolution of pMRI compared with MRI, the distance from the optic chiasm to the top of the third ventricle was measured, and the measurements were compared between paired equivalent slices on T2-weighted coronal images. The inter- and intrarater correlations were analyzed.RESULTS Twelve patients were included in this study (10 with pituitary adenomas and 2 with craniopharyngiomas) with varying degrees of optic chiasm compression on preoperative imaging. Measurements were averaged across raters before calculating agreement between pMRI and MRI, which demonstrated significant interrater reliability (intraclass correlation coefficient [ICC] = 0.78, p < 0.01). Agreement between raters within the pMRI measurements was also significantly reliable (ICC = 0.93, p < 0.01). Finally, a linear mixed-effects model was specified to demonstrate that MRI measurement could be predicted using the pMRI measurement with the patient and rater set as random effects (pMRI beta coefficient = 0.80, p < 0.01). CONCLUSIONS The results of this study suggest that resolution of pMRI is comparable to that of conventional MRI in assessing the optic chiasm position in relation to the third ventricle. Portable MRI sufficiently demonstrates decompression of the optic chiasm after endoscopic endonasal surgery. It can be an alternative strategy in cases in which cost, scan-time considerations, or lack of intraoperative MRI availability may preclude the ability to assess adequate optic nerve decompression after endoscopic endonasal surgery for sellar and suprasellar lesions.}, keywords = {MRI; craniopharyngioma; pituitary surgery; endoscopic endonasal surgery; low Tesla}, year = {2023}, eissn = {1933-0693}, pages = {1664-1670} } @article{MTMT:34586120, title = {Brain plasticity and age after restoring elbow flexion with distal nerve transfers in neonatal brachial plexus palsy and nonneonatal traumatic brachial plexus injury using the plasticity grading scale}, url = {https://m2.mtmt.hu/api/publication/34586120}, author = {Socolovsky, Mariano and Lovaglio, Ana and Bonilla, Gonzalo and Di Masi, Gilda and Barillaro, Karina and Malessy, Martijn}, doi = {10.3171/2023.5.JNS23673}, journal-iso = {J NEUROSURG}, journal = {JOURNAL OF NEUROSURGERY}, volume = {139}, unique-id = {34586120}, issn = {0022-3085}, abstract = {OBJECTIVE Ulnar and/or median nerve fascicle to musculocutaneous nerve (MCN) transfers are used to restore elbow flexion following severe neonatal and nonneonatal brachial plexus injuries (BPIs). Restoring volitional control requires plastic changes in the brain. To date, whether the potential for plasticity is influenced by a patient's age remains unknown.METHODS Patients who had presented with a traumatic upper (C5-6 or C5-7) BPI were divided into two groups: neonatal brachial plexus palsies (NBPPs) and nonneonatal traumatic BPIs (NNBPIs). Both groups underwent ulnar or median nerve transfers to the MCN for elbow flexion restoration between January 2002 and July 2020. Only those who attained a British Medical Research Council strength rating of 4 were reviewed. The primary comparison between the two groups was the plasticity grading scale (PGS) score to determine the level of independence of elbow flexion (target) from forearm motor muscle movement (donors). The authors also assessed patient compliance with rehabilitation using a 4-point Rehabilitation Quality Scale. Bivariable and multivariable analyses were used to identify intergroup differences.RESULTS In total, 66 patients were analyzed: 22 with NBPP (mean age at surgery 10 months) and 44 with NNBPI (age range at surgery 3-67 years, mean 30.2 years; mean time to surgery 7 months, p < 0.001). All NBPP patients obtained a PGS grade of 4 at the final follow-up versus just 47.7% of NNBPI patients (mean 3.27, p < 0.001). On ordinal regression analysis, after nature of the injury was excluded because of excessive collinearity with age, age was the only significant predictor of plasticity (beta = -0.063, p = 0.003). Median rehabilitation compliance scores were not statistically different between the two groups.CONCLUSIONS The extent of plastic changes that occur for patients to regain volitional control over elbow flexion after upper arm distal nerve transfers following BPI is influenced by patient age, with complete plastic rewiring more likely in younger patients and virtually ubiquitous in infants. Older patients should be informed that elbow flexion after an ulnar or median nerve fascicle transfer to the MCN might require simultaneous wrist flexion.}, keywords = {peripheral nerve; brain plasticity; Nerve transfer; brachial plexus injury; neonatal brachial plexus palsy; Plasticity Grading Scale; Neuroplasticity Score}, year = {2023}, eissn = {1933-0693}, pages = {1568-1575} } @article{MTMT:34583605, title = {The ivy sign as a radiological marker for follow-up of postoperative cerebral perfusion status in adult moyamoya disease}, url = {https://m2.mtmt.hu/api/publication/34583605}, author = {Lee, Sung Ho and Cho, Won-Sang and Lee, Hee Chang and Oh, Hansan and Bae, Jin Woo and Choi, Young Hoon and Paeng, Jin Chul and Gil, Joonhyung and Kim, Kangmin and Kang, Hyun-Seung and Kim, Jeong Eun}, doi = {10.3171/2023.4.JNS23294}, journal-iso = {J NEUROSURG}, journal = {JOURNAL OF NEUROSURGERY}, volume = {139}, unique-id = {34583605}, issn = {0022-3085}, abstract = {OBJECTIVE Little is known about the relationship between postoperative changes in cerebral perfusion and the ivy sign representing leptomeningeal collateral burden in moyamoya disease (MMD). This study aimed to investigate the usefulness of the ivy sign in evaluating cerebral perfusion status following bypass surgery in patients with adult MMD.METHODS Two hundred thirty-three hemispheres in 192 patients with adult MMD undergoing combined bypass between 2010 and 2018 were retrospectively enrolled. The ivy sign was represented as the ivy score on FLAIR MRI in each territory of the anterior, middle, and posterior cerebral arteries. Ivy scores, as well as clinical and hemodynamic states on SPECT, were semiquantitatively compared both preoperatively and at 6 months after surgery.RESULTS Clinical status improved at 6 months after surgery (p < 0.01). On average, ivy scores in whole and individual territories were decreased at 6 months (all p values < 0.01). Cerebral blood flow (CBF) postoperatively improved in three individual vascular territories (all p values <= 0.03) except for the posterior cerebral artery territory (PCAt), and cerebrovascular reserve (CVR) improved in those areas (all p values <= 0.04) except for the PCAt. Postoperative changes in ivy scores and CBF were inversely correlated in all territories (p <= 0.02), except for the PCAt. Furthermore, changes in ivy scores and CVR were only correlated in the posterior half of the middle cerebral artery territory (p = 0.01).CONCLUSIONS The ivy sign was significantly decreased after bypass surgery, which was well correlated with postoperative hemodynamic improvement in the anterior circulation territories.

Minimally invasive endoscopic evacuation is a promising therapeutic approach for ICH. In this study the authors examined prognostic factors associated with long-term functional dependence (modified Rankin Scale [mRS] score >= 4) in patients who had undergone endoscopic evacuation of basal ganglia hemorrhage.Methods: In total, 222 consecutive patients who underwent endoscopic evacuation between July 2019 and April 2022 at four neurosurgical centers were enrolled prospectively. Patients were dichotomized into functionally independent (mRS score <= 3) and functionally dependent (mRS score >= 4) groups. Hematoma and perihematomal edema (PHE) volumes were calculated using 3D Slicer software. Predictors of functional dependence were assessed using logistic regression models.Results: Among the enrolled patients, the functional dependence rate was 45.50%. Factors independently associated with long-term functional dependence included female sex, older age (>= 60 years), Glasgow Coma Scale score <= 8, larger preoperative hematoma volume (OR 1.02), and larger postoperative PHE volume (OR 1.03, 95% CI 1.01-1.05). A subsequent analysis evaluated the effect of stratified postoperative PHE volume on functional dependence. Specifically, patients with large (>= 50 to < 75 ml) and extra-large (>= 75 to 100 ml) postoperative PHE volumes had 4.61 (95% CI 0.99-21.53) and 6.75 (95% CI 1.20-37.85) times greater likelihood of long-term dependence, respectively, than patients with a small postoperative PHE volume (>= 10 to < 25 ml).Conclusions: A large postoperative PHE volume is an independent risk factor for functional dependence among basal ganglia hemorrhage patients after endoscopic evacuation, especially with postoperative PHE volume >= 50 ml.}, keywords = {EXPANSION; MANAGEMENT; GUIDELINES; OUTCOMES; ANTIPLATELET THERAPY; Minimally invasive; Intracerebral hemorrhage; Clinical Neurology; early surgery; perihematomal edema; basal ganglia hemorrhage; Hematomas; endoscopic evacuation; ACUTE INTRACEREBRAL HEMORRHAGE; INITIAL CONSERVATIVE TREATMENT}, year = {2023}, eissn = {1933-0693}, pages = {1784-1791} } @article{MTMT:34322253, title = {Effectiveness of immune checkpoint inhibitors in combination with stereotactic radiosurgery for patients with brain metastases from renal cell carcinoma: inverse probability of treatment weighting using propensity scores}, url = {https://m2.mtmt.hu/api/publication/34322253}, author = {Yomo, Shoji and Oda, Kyota and Oguchi, Kazuhiro}, doi = {10.3171/2022.9.JNS221215}, journal-iso = {J NEUROSURG}, journal = {JOURNAL OF NEUROSURGERY}, volume = {138}, unique-id = {34322253}, issn = {0022-3085}, abstract = {OBJECTIVE Stereotactic radiosurgery (SRS) is the mainstay for treating brain metastases (BMs) from renal cell carcinoma (RCC). In recent years, immune checkpoint inhibitors (ICIs) have been applied to metastatic RCC and have contributed to improved outcomes. The authors investigated whether SRS with concurrent ICIs for RCC BM prolongs overall survival (OS) and improves intracranial disease control and whether there are any safety concerns.METHODS Patients who underwent SRS for RCC BMs at the authors' institution between January 2010 and January 2021 were included. Concurrent use of ICIs was defined as no more than 3 months between SRS and ICI administration. The time-to-event analysis of OS and intracranial progression-free survival (IC-PFS) between the groups with and without ICIs (ICI+SRS and SRS, respectively) was performed using inverse probability of treatment weighting (IPTW) based on propensity scores (PSs) to control for selection bias. Four baseline covariates (Karnofsky Performance Scale score, extracranial metastases, hemoglobin, and number of BMs) were selected to calculate PSs.RESULTS In total, 57 patients with 147 RCC BMs were eligible. The median OS for all patients was 9.1 months (95% CI 6.0-18.9 months), and the median IC-PFS was 4.4 months (95% CI 3.1-6.8 months). Twelve patients (21%) received concurrent ICIs. The IPTW-adjusted 1-year OS rates in the ICI+SRS and SRS groups were 66% and 38%, respectively (HR 0.30, 95% C 0.13-0.69; p = 0.005), and the IPTW-adjusted 1-year IC-PFS rates were 52% and 16%, respectively (HR 0.30, 95% CI 0.14-0.62; p = 0.001). Severe tumor hemorrhage (Common Terminology Criteria for Adverse Events [CTCAE] grade 4 or 5) occurred immediately after SRS in 2 patients in the SRS group. CTCAE grade 2 or 3 toxicity was observed in 2 patients in the ICI+SRS group and 5 patients in the SRS group.CONCLUSIONS Although the patient number was small and the analysis preliminary, the present study found that SRS with concurrent ICIs for RCC BM patients prolonged survival and provided durable intracranial disease control, with no apparent increase in treatment-related adverse events.}, keywords = {Oncology; Renal cell carcinoma; brain metastases; stereotactic radiosurgery; immune checkpoint inhibitors; Gamma knife; inverse probability treatment weighted analysis}, year = {2023}, eissn = {1933-0693}, pages = {1591-1599}, orcid-numbers = {Yomo, Shoji/0000-0001-7426-7654} }
