Prognostic Analysis of a Hypoxia-Associated lncRNA Signature in Glioblastoma and its Pan-Cancer Landscape J. Neurol. Surg. Part A Central Eur. Neurosurg. (IF 1.0) Pub Date : 2023-07-31 Yue Qin, Xiaonan Zhang, Yulei Chen, Wan Zhang, Shasha Du, Chen Ren
Background Hypoxia is an important clinical feature of glioblastoma (GBM), which regulates a variety of tumor processes and is inseparable from radiotherapy. Accumulating evidence suggests that long noncoding RNAs (lncRNAs) are strongly associated with survival outcomes in GBM patients and modulate hypoxia-induced tumor processes. Therefore, the aim of this study was to establish a hypoxia-associated

Laminoplasty in Motion: Evolving Techniques and Complications J. Neurol. Surg. Part A Central Eur. Neurosurg. (IF 1.0) Pub Date : 2023-07-28 Ian M. Singleton, Amit S. Piple, Ben Crawford, Ashish Mittal, Alexander A. Rosinski, Dimitriy G. Kondrashov
Cervical laminoplasty is an increasingly popular surgical option for the treatment of cervical spondylotic myelopathy (CSM) and ossification of the posterior longitudinal ligament (OPLL). Over the past few decades, there have been substantial developments in both surgical technique and hardware options. As the field of cervical surgery rapidly evolves, there is a timely need to reassess the evolving

PEEK Cages versus Titanium-Coated PEEK Cages in Single-Level Anterior Cervical Fusion: A Randomized Controlled Study J. Neurol. Surg. Part A Central Eur. Neurosurg. (IF 1.0) Pub Date : 2023-07-28 Johannes Schröder, Thomas Kampulz, Sonunandita K. Bajaj, Arnd Georg Hellwig, Michael Winking
Background The implantation of a spacer is a common practice after anterior diskectomy in cervical spine. Polyether ether ketone (PEEK) cages have replaced titanium implants due to their better radiologic visibility and appearance in postoperative magnetic resonance imaging (MRI) scans. However, PEEK showed apparently higher nonunion rates than titanium cages. The aim of the study was to evaluate the

Effect of Sleep Deprivation on Simulated Microsurgical Vascular Anastomosis J. Neurol. Surg. Part A Central Eur. Neurosurg. (IF 1.0) Pub Date : 2023-07-28 Yoshiro Ito, Ahmad Hafez, Hisayuki Hosoo, Aiki Marushima, Yuji Matsumaru, Eiichi Ishikawa
Background The effects of sleep deprivation on surgical performance have been well documented. However, reports on the effects of sleep deprivation on microneurosurgery are limited. This study aimed to investigate the effects of sleep deprivation on microneurosurgery. Methods Ten neurosurgeons participated in the anastomosis of a vessel model using a microscope in sleep-deprived and normal states.

The Early Postoperative Course of Cognitive Function and Preoperative Cerebrovascular Reserve J. Neurol. Surg. Part A Central Eur. Neurosurg. (IF 1.0) Pub Date : 2023-07-28 Masashi Ikota, Mami Ishikawa, Gen Kusaka
Background Patients with severe steno-occlusive disease of a main cerebral artery without causative lesions on magnetic resonance imaging (MRI) often develop cognitive impairment. However, the effects of revascularization surgery and the source of the cognitive impairment remain unclear. Therefore, we investigated the early postoperative course of cognitive function and its association with cerebral

Neuroendoscopic Lavage and Third Ventriculostomy for the Treatment of Intraventricular Hemorrhage and Hydrocephalus in Neonates. A Prospective Study with 18 Months of Follow-Up J. Neurol. Surg. Part A Central Eur. Neurosurg. (IF 1.0) Pub Date : 2023-07-28 Mario Islas Aguilar, Jaime Gerardo Torrez-Corzo, Juan Carlos Chalita-Williams, Dominic Shelby Cervantes, Juan Vinas-Rios
Background Neonatal intraventricular hemorrhage (IVH) may evolve into posthemorrhagic hydrocephalus and cause neurodevelopmental impairment, becoming a common complication of premature infants, occurring in up to 40% of preterm infants weighing less than 1,500 g at birth. Around 10 to 15% of preterm infants develop severe (grades III–IV) IVH. These infants are at high risk of developing posthemorrhagic

Microsurgical Clipping after Failed Contour Device Embolization of an Anterior Communicating Artery Aneurysm: Technical Note J. Neurol. Surg. Part A Central Eur. Neurosurg. (IF 1.0) Pub Date : 2023-07-26 Christoph J. Griessenauer, Monika Killer-Oberpfalzer, Carlos M. Beredjiklian, Manuel Lunzer
Background Endovascular therapy has revolutionized the treatment of cerebral aneurysms in recent years and decades. So-called intrasaccular devices (i.e., Woven EndoBridge [WEB], MicroVention, Aliso Viejo, California, United States; or Contour, Cerus Neurovascular, Fremont, California, United States) are a promising endovascular technology, especially for wide-based aneurysms. However, long-term outcome

A Review of Strategies Associated with Surgical Decompression in Traumatic Spinal Cord Injury J. Neurol. Surg. Part A Central Eur. Neurosurg. (IF 1.0) Pub Date : 2023-07-26 Ying-kang Zhu, Fa-tai Lu, Guo-dong Zhang, Zun-peng Liu
Traumatic spinal cord injury (TSCI) is frequent. Timely diagnosis and treatment have reduced the mortality, but the long-term recovery of neurologic functions remains ominous. After TSCI, tissue bleeding, edema, and adhesions lead to an increase in the intraspinal pressure, further causing the pathophysiologic processes of ischemia and hypoxia and eventually accelerating the cascade of secondary spinal

Survey on Training Satisfaction among German Neurosurgical Trainees J. Neurol. Surg. Part A Central Eur. Neurosurg. (IF 1.0) Pub Date : 2023-07-26 Anna Cecilia Lawson McLean, Stefanie Maurer, Dorothea Nistor-Gallo, Ina Moritz, Meriem Tourbier
Background There has been a fivefold increase of neurosurgeons over the last three decades in Germany, despite a lesser increase in operations. Currently, there are approximately 1,000 neurosurgical residents employed at training hospitals. Little is known about the overall training experience and career opportunities for these trainees. Methods In our role as resident representatives, we implemented

Endovascular Treatment of Brain Arteriovenous Malformations in Pediatric Patients: A Single Center Experience and Review of the Literature J. Neurol. Surg. Part A Central Eur. Neurosurg. (IF 1.0) Pub Date : 2023-07-26 Gonçalo Borges de Almeida, Jaime Pamplona, Mariana Baptista, Rui Carvalho, Carla Conceição, Rita Lopes da Silva, Amets Sagarribay, João Reis, Isabel Fragata
Background Brain arteriovenous malformations (bAVMs) are abnormal vascular connections with direct arteriovenous shunts, generally symptomatic in the adult life. However, a small number of bAVMs may manifest in pediatric patients, with higher bleeding risk and mortality rates when compared to adults. The purpose of this study is to review our experience with endovascular treatment of bAVMs in pediatric

Growth of Flow-Related Aneurysms Following Occlusion of Cerebral Arteriovenous Malformation J. Neurol. Surg. Part A Central Eur. Neurosurg. (IF 1.0) Pub Date : 2023-07-26 Wojciech Świątnicki
Background Flow-related aneurysms (FRAs) associated with cerebral arteriovenous malformations (AVMs) pose a significant therapeutic challenge. Both their natural history and management strategy are still unclear and underreported. FRAs generally increase the risk of brain hemorrhage. However, following AVM obliteration these vascular lesions are expected to disappear or remain stable. Methods We present

Comparison of ALIF and PLIF in Isthmic Lumbosacral Spondylolisthesis. A Multicenter Surveillance Study of 602 cases from the German Spine Registry (DWG Register) J. Neurol. Surg. Part A Central Eur. Neurosurg. (IF 1.0) Pub Date : 2023-07-10 Lore Marie Bock, Michael Rauschmann, Vincent Heck, Richard Sellei, Juan Manuel Vinas-Rios
Background Isthmic spondylolisthesis most commonly occurs in the lumbosacral junction and can cause backpain and radicular pain as well as stiffness with progressive immobilization, with a negative impact on an individual's ability to work and quality of life. Multiple operative treatments are currently available. This study aims to compare complications, demography, and clinical features between anterior
