Flow-diverter stents in the early management of acutely ruptured brain aneurysms: effective rebleeding protection with low thromboembolic complications
CONCLUSIONS: Flow diversion is an effective therapeutic strategy for the management of select acutely ruptured aneurysms. Despite low rates of immediate aneurysm occlusion after FDS implantation, the device exerts an important protective effect. The authors' experience confirmed no aneurysm rerupture, high rates of delayed complete occlusion, and complication rates that compare favorably with the rates obtained using other techniques.PMID:33862594 | DOI:10.3171/2020.10.JNS201642 (Source: Journal of Neurosurgery)

Online ahead of print.ABSTRACTOBJECTIVE: To date, muscular and bone pain have been studied in domestic swine models, but the only neuropathic pain model described in swine is a mixed neuritis model. Common peroneal nerve injury (CPNI) neuropathic pain models have been utilized in both mice and rats.METHODS: The authors developed a swine surgical CPNI model of neuropathic pain. Behavioral outcomes were validated with von Frey filament testing, thermal sensitivity assessments, and social and motor scoring. Demyelination of the nerve was confirmed through standard h...

Microsurgical anatomy of the lateral posterior choroidal artery: implications for intraventricular surgery involving the choroid plexus
CONCLUSIONS: The LPChA typically runs in the medial border of the choroid plexus, which may facilitate its recognition during surgery. The distance between the AChA at the inferior choroidal point and the LPChA is a valuable reference during surgery, but there are cases of posterior choroidal entrance. Most frequently, there are 2 or more LPChA trunks, which makes possible the sacrifice of one trunk feeding the tumor while preserving the other that provides supply to relevant structures. The intraventricular approaches can be selected based on the tumor location and the LPChA anatomy.PMID:33836500 | DOI:10.3171/2020.8.JNS2...

Outcomes for various dural graft materials after posterior fossa decompression with duraplasty for Chiari malformation type I: a systematic review and meta-analysis
CONCLUSIONS: Autograft was the dural graft material that most frequently had the lowest rate of complications and was associated with significantly lower rates of pseudomeningocele compared to collagen-based graft, allograft, and nonautologous graft materials. Autografts and nonautologous grafts yielded similar outcomes for revision surgery, symptoms, and syrinx size. Large prospective studies comparing different graft materials are needed to accurately and precisely characterize outcomes for individual graft types.PMID:33836504 | DOI:10.3171/2020.9.JNS202641 (Source: Journal of Neurosurgery)

Tumor location and reduction in functional MRI estimates of language laterality
CONCLUSIONS: Patients with tumors close to Broca's area showed more bilateral fMRI language maps independent of known confounders. The authors caution against the assumption that this reduced language laterality suggests no or little risk to language function following tumor resection in the left inferior frontal gyrus. Their results address how to interpret fMRI data for neurosurgical purposes, along with theoretical questions of contralesional functional compensation and disinhibition.PMID:33799298 | DOI:10.3171/2020.9.JNS202036 (Source: Journal of Neurosurgery)

Charcot's motor brain map and 19th-century neurosurgery
J Neurosurg. 2021 Apr 2:1-6. doi: 10.3171/2020.10.JNS202651. Online ahead of print.ABSTRACTNeurosurgery is predicated on the knowledge of the structure-function relationship of the brain. When the topic is broached in its historiography, it begins with Fritch and Hitzig's report on the localization of motor function in the cortex of the dog and skips rapidly to Wilder Penfield's homunculus. In that gap are found the origins of modern neurosurgery in 3 papers published by Jean-Martin Charcot and Albert Pitres between 1877 and 1879 in which they describe the somatotopic organization of the human motor cortex and draw the fir...

Opioids are the mainstay of treatment, but opioid abuse has led to an epidemic in the United States. Nonpharmacological treatment strategies like deep brain stimulation could be applied to refractory chronic pain if safe and effective brain targets are identified. The anterior insula is a putative mediator of pain-related affective-motivational and cognitive-evaluative cerebral processing. However, the effect of anterior insula stimulation on pain perceptio...

Endovascular treatment for calcified cerebral emboli in patients with acute ischemic stroke
CONCLUSIONS: While patients with CCE had significantly lower reperfusion rates and less improvement on the NIHSS after EVT, CCE were not significantly associated with worse functional outcome or higher mortality rates.

Charcot's motor brain map and 19th-century neurosurgery
J Neurosurg. 2021 Apr 2:1-6. doi: 10.3171/2020.10.JNS202651. Online ahead of print.ABSTRACTNeurosurgery is predicated on the knowledge of the structure-function relationship of the brain. When the topic is broached in its historiography, it begins with Fritch and Hitzig's report on the localization of motor function in the cortex of the dog and skips rapidly to Wilder Penfield's homunculus. In that gap are found the origins of modern neurosurgery in 3 papers published by Jean-Martin Charcot and Albert Pitres between 1877 and 1879 in which they describe the somatotopic organization of the human motor cortex and draw the fir...

Anterior insula stimulation increases pain threshold in humans: a pilot study
J Neurosurg. 2021 Apr 2:1-6. doi: 10.3171/2020.10.JNS203323. Online ahead of print.ABSTRACTOBJECTIVE: Chronic pain results in an enormous societal and financial burden. Opioids are the mainstay of treatment, but opioid abuse has led to an epidemic in the United States. Nonpharmacological treatment strategies like deep brain stimulation could be applied to refractory chronic pain if safe and effective brain targets are identified. The anterior insula is a putative mediator of pain-related affective-motivational and cognitive-evaluative cerebral processing. However, the effect of anterior insula stimulation on pain perceptio...

Endovascular treatment for calcified cerebral emboli in patients with acute ischemic stroke
CONCLUSIONS: While patients with CCE had significantly lower reperfusion rates and less improvement on the NIHSS after EVT, CCE were not significantly associated with worse functional outcome or higher mortality rates. Therefore, EVT should still be considered in this specific group of patients.PMID:33799302 | DOI:10.3171/2020.9.JNS201798 (Source: Journal of Neurosurgery)

Endoscope-assisted far-lateral transcondylar approach for craniocervical junction chordomas: a retrospective case series and cadaveric dissection
CONCLUSIONS: The EA-FLTA provides a safe and effective corridor to resect extensive and complex CCJ chordomas, allowing the surgeon to reach the anterior, lateral, and posterior portions of the tumor, and to treat CCJ instability in a single stage.PMID:33799304 | DOI:10.3171/2020.9.JNS202611 (Source: Journal of Neurosurgery)

The Stanford stereotactic radiosurgery experience on 7000 patients over 2 decades (1999-2018): looking far beyond the scalpel
J Neurosurg. 2021 Apr 2:1-17. doi: 10.3171/2020.9.JNS201484. Online ahead of print.ABSTRACTOBJECTIVE: The CyberKnife (CK) has emerged as an effective frameless and noninvasive method for treating a myriad of neurosurgical conditions. Here, the authors conducted an extensive retrospective analysis and review of the literature to elucidate the trend for CK use in the management paradigm for common neurosurgical diseases at their institution.METHODS: A literature review (January 1990-June 2019) and clinical review (January 1999-December 2018) were performed using, respectively, online research databases and the Stanford Resea...

Tumor location and reduction in functional MRI estimates of language laterality
CONCLUSIONS: Patients with tumors close to Broca's area showed more bilateral fMRI language maps independent of known confounders.
