Predictive factors for pre-intervention rebleeding in aneurysmal subarachnoid haemorrhage: a systematic review and meta-analysis.

Rebleeding before intervention is a devastating complication of aneurysmal subarachnoid haemorrhage (aSAH). It often occurs early and is associated with poor outcomes. We present a systematic review and meta-analysis to identify potential predictors of rebleeding in aSAH.

Elective intervention for unruptured cranial arteriovenous malformations in relation to ARUBA trial: a National Inpatient Sample study.

Background: In 2014, A Randomized Trial of Unruptured Brain Arteriovenous Malformations (ARUBA) concluded that medical management alone for cranial arteriovenous malformations (AVMs) had better clinical outcomes than interventional treatment. The impact of the ARUBA study on changes in the rates of intervention and outcomes is unknown. Thus, we investigated whether the conclusions from ARUBA may have influenced treatment modalities and outcomes of unruptured AVMs.

Determining the Difference in Clinical and Radiologic Outcomes Between Expandable and Nonexpandable Titanium Cages in Cervical Fusion Procedures: A Systematic Review and Meta-Analysis.

Background: Expandable cages have been increasingly used in cervical and lumbar reconstructions; however, there is a paucity in the literature on how they compare with traditional nonexpandable cages in the cervical spine. We present a systematic review and meta-analysis, comparing the clinical and radiologic outcomes of expandable versus nonexpandable corpectomy cage use in the cervical spine.

Methods: A database search identified studies detailing the outcomes of expandable and nonexpandable titanium cage use in the cervical spine.

Internal maxillary artery to middle cerebral artery bypass for a complex recurrent middle cerebral artery aneurysm: case report and technical considerations.

We report the case of a 41-year-old male who presented with an enlarging aneurysm neck one year after clipping. The patient underwent an IMAX-MCA bypass followed by endovascular coil occlusion of the aneurysm neck incorporating an MCA branch origin. To our knowledge, this case represents the first documented IMAX-MCA bypass from a European centre.

Is postoperative atelectasis following lumbar fusion more prevalent among patients with chronic opioid use?

Objective: Chronic opioid use (COU) remains on the rise globally, acting as a marker for patient morbidity and a risk factor for adverse health outcomes. Opioid use is a risk factor for respiratory depression, which may lead to dysfunctional breathing, a known cause of atelectasis. The objective of this study was to determine whether COU is associated with increased rates of postoperative atelectasis among patients undergoing lumbar fusion.

Chronic opioid use is associated with increased postoperative urinary retention, length of stay and non-routine discharge following lumbar fusion surgery.

Background: The incidence of chronic opioid use (COU) is increasing with health related complications impacting both patients and healthcare services.

Objective: The aim of this study was to identify the impact of COU on postoperative urinary retention (PUR) in patients following lumbar fusion surgery as well as its impact on length of stay (LOS) and non-routine discharges (NRD).

Materials & Methods: The State Inpatient Databases were utilised to identify patients undergoing elective lumbar fusion procedures.

Moyamoya disease and moyamoya syndrome in Ireland: patient demographics, mode of presentation and outcomes of EC-IC bypass surgery.

Background: There are no previously published reports regarding the epidemiology and characteristics of moyamoya disease or syndrome in Ireland.

Aims: To examine patient demographics, mode of presentation and the outcomes of extracranial-intracranial bypass surgery in the treatment of moyamoya disease and syndrome in Ireland.

Methods: All patients with moyamoya disease and syndrome referred to the National Neurosurgical Centre during January 2012-January 2019 were identified through a prospective database.
