Iatrogenic post-surgical tension pneumosyrinx-a first reported case.

Acta Neurochir (Wien) 2022 Jun 27. Epub 2022 Jun 27.

Department of Neurosurgery, King's College Hospital NHS Foundation Trust, Denmark Hill, London, SE5 9RS, UK.

We describe the first ever-reported occurrence of a post-operative tension pneumosyrinx occurring after a resection of an intradural intramedullary spinal tumour in a 40-year-old patient. Post-operatively, he developed sudden onset paraplegia and imaging revealed a tension pneumosyrinx which was subsequently surgically decompressed. He made a gradual neurological recovery. Read More

Lariboisiere Hospital pre-operative surgical checklist to improve safety during transpetrosal approaches.

Acta Neurochir (Wien) 2022 Jun 25. Epub 2022 Jun 25.

Department of Neurosurgery, I.R.C.C.S. Neuromed, Pozzilli, IS, Italy.

Background: Transpetrosal approaches are technically complex and require a complete understanding of surgical and radiological anatomy. A careful evaluation of pre-operative magnetic resonance imaging and computed tomography scan is mandatory, because anatomical or pathological variations are common and may increase the risk of complications related with the approach.

Methods: Pre-operative characteristics of venous and petrous bone anatomy were analysed and correlated with intraoperative findings, using injected magnetic resonance imaging and thin-slices computed tomography scan. Read More

Subthalamic nucleus deep brain stimulation programming settings do not correlate with Parkinson's disease severity.

Acta Neurochir (Wien) 2022 Jun 25. Epub 2022 Jun 25.

Department of Clinical Neurosciences, University of Calgary, 1403 29 Street NW, Calgary, AB, T2N 2T9, Canada.

Background: Deep brain stimulation (DBS) is a well-established treatment for Parkinson's disease (PD). While the success of DBS is dependent on careful patient selection and accurate lead placement, programming parameters play a pivotal role in tailoring therapy on the individual level. Various algorithms have been developed to streamline the initial programming process, but the relationship between pre-operative patient characteristics and post-operative device settings is unclear.

Genetic predisposition to central nervous system tumors in children - what the neurosurgeon should know.

Acta Neurochir (Wien) 2022 Jun 3. Epub 2022 Jun 3.

The Pediatric Oncology Research Laboratory, Department of Pediatrics and Adolescent Medicine, Rigshospitalet University Hospital, Blegdamsvej 9, 2100, Copenhagen, Denmark.

Background: Historically, few pediatric central nervous system (CNS) tumors were thought to result from genetic predisposition.

Sevoflurane anesthesia rather than propofol anesthesia is associated with 3-month postoperative hypocortisolism in patients undergoing endoscopic transsphenoidal surgery for non-functional pituitary adenoma with preoperative normal hypothalamic-pituitary-adrenal axis.

Acta Neurochir (Wien) 2022 May 31. Epub 2022 May 31.

Department of Anesthesiology and Pain Medicine, Seoul National University Hospital, Seoul National University College of Medicine, 101 Daehak-ro, Jongno-gu, Seoul, 03080, Korea.

C-reactive protein elevation predicts in-hospital deterioration after aneurysmal subarachnoid hemorrhage: a retrospective observational study.

Acta Neurochir (Wien) 2022 Jul 26;164(7):1805-1814. Epub 2022 May 26.

Division of Anaesthesiology, Intensive Care, Rescue and Pain Medicine, Kantonsspital St. Gallen, St. Gallen, Switzerland.

Background: There is increasing evidence that inflammation plays a role in the pathogenesis of aneurysmal subarachnoid hemorrhage (aSAH) and in the development of delayed cerebral ischemia (DCI). However, the assessment and interpretation of classically defined inflammatory parameters is difficult in aSAH patients. The objective of this study was to investigate the relationship between easily assessable findings (hyperventilation, fever, white blood cell count (WBC), and C-reactive protein (CRP)) and the occurrence of DCI and unfavorable neurological outcome at discharge in aSAH patients.

Variations of perforating arteries of anterior communicating artery in cases with anterior communicating artery aneurysms: a cadaveric anatomical study.

Acta Neurochir (Wien) 2022 May 26. Epub 2022 May 26.

Department of Neurosurgery, Uludag University Medical Faculty, Bursa, Turkey.

Purpose: In terms of postoperative morbidity and mortality, preservation of the perforating arteries branching from the anterior communicating artery (ACoA) during clipping is particularly imperative in patients with ACoA aneurysm. In the present study, we aimed to investigate whether perforating arteries originated from ACoA were pushed away in a different location in patients with ACoA aneurysm. Furthermore, if they did so, we aimed to identify the direction in which they were dislocated and how the perforating arteries could be preserved during clipping. Read More
