Background: There are limited therapeutic options in cases of failed reperfusion (modified thrombolysis in cerebral infarction [mTICI] score < 2b) after stent-retriever and/or aspiration based endovascular treatment (EVT) for acute ischemic stroke. Despite the absence of data supporting its use, rescue therapy (balloon angioplasty and/or stent implantation) is often utilized in such cases. Studies are limited to large vessel occlusions, while the outcomes and complications after rescue therapy in medium/distal vessel occlusions (MDVOs) have not been reported.

Objective: Malalignment following cervical spine deformity (CSD) surgery can negatively impact outcomes and increase complications. Despite the growing ability to plan alignment, it remains unclear whether preoperative goals are achieved with surgery. The objective of this study was to assess how good surgeons are at achieving their preoperative goal alignment following CSD surgery.

The Woven EndoBridge (WEB) device has become a prominent treatment for wide-neck bifurcation intracranial aneurysms since its FDA approval in 2018. However, the impact of anticoagulant therapy on its efficacy and patient outcomes remains underexplored. This study aims to evaluate the effects of postoperative anticoagulant use on aneurysm occlusion, retreatment rates, and functional outcomes following WEB device implantation.

Background: Patients receiving standard treatment for chronic subdural hematoma have a high risk of treatment failure. The effect of adjunctive middle meningeal artery embolization on the risk of treatment failure in this population remains unknown.

Methods: We randomly assigned patients with symptomatic chronic subdural hematoma to undergo middle meningeal artery embolization as an adjunct to standard treatment (embolization group) or to receive standard treatment alone (control group).

Background: The duration of mechanical thrombectomy (MT) is a negative predictor of outcomes in acute ischemic stroke (AIS), yet the precise mechanisms are unclear. We investigated whether the placement of large-bore catheters intracranially reduces blood flow to the ischemic penumbra and diminishes the efficacy of MT.

Methods: We investigated the impact of different catheter sizes on flow through the intracranial circulation using an in vitro model.

Background: Endovascular treatment of internal carotid artery (ICA) pathology includes reconstructive or deconstructive options. One reconstructive option is covered stent placement, although this is limited by a lack of devices designed specifically for neurointervention. The PK Papyrus is a balloon-mounted covered coronary stent that has a lower profile and is more flexible than other stent grafts, which makes it more suitable for treating ICA lesions.

Article Synopsis
  • Researchers aimed to create and validate a prediction score for futile recanalization (FR) in patients with low Alberta Stroke Program Early Computed Tomography Scores (ASPECTS) who underwent endovascular thrombectomy (EVT) for large vessel occlusions (LVO).
  • The study analyzed data from 219 patients with anterior circulation LVO and identified key predictors of FR, resulting in the development of the SNAP score, which considers factors like the site of occlusion and patient age.
  • The SNAP score successfully predicted FR with an area under the curve of 0.79 in both training and validation cohorts, indicating its potential usefulness for guiding expectations in patients undergoing EVT for severe strokes.

Background: An estimated 185,000 patients per year undergo an extremity amputation in the United States (over 500 amputations/day). Prolonged postoperative opioid use, defined as the presence of a filled opioid prescription between 90 and 180 days following the operative amputation procedure, affects nearly 50% of amputees. Moreover, the use of preoperative benzodiazepines, muscle relaxants, anticonvulsants, and antidepressants is strongly linked to prolonged opioid use suggesting new therapeutic strategies are needed.

Article Synopsis
  • The study explores the impact of revision surgery on patient-reported outcomes (PROs) following initial surgeries for grade 1 spondylolisthesis, comparing decompression-only and decompression plus fusion (D+F) treatments.
  • Data was collected from over 600 patients, revealing that 13.3% of decompression-only patients and 9.8% of D+F patients required revision surgery within 5 years, with revision patients reporting worse outcomes.
  • The findings indicate that while revision surgery affects PROs adversely, patients undergoing D+F see a more significant decline in their reported outcomes compared to those who only had decompression surgery.

  • - The study investigates the link between county-level air pollution, specifically PM2.5, and stroke mortality rates in U.S. residents aged 65 and older, focusing on how these effects differ based on race and socioeconomic status.
  • - An analysis of data from 2016-2020 shows a significant increase in ischemic stroke deaths correlating with higher PM2.5 levels, with the most severe impact observed in counties with predominantly Black populations and those facing persistent poverty.
  • - Findings highlight that counties with larger Black populations are more likely to exceed EPA air quality standards, experiencing greater increases in stroke mortality with rising air pollution levels compared to other demographic groups.

Article Synopsis
  • The study looked at whether a medical procedure called thrombectomy helps patients who have a large stroke as seen on a specific type of scan called a noncontrast CT within 24 hours of having the stroke.
  • It involved 300 patients from different hospitals who were split into two groups; one group received the thrombectomy treatment, while the other only received regular care.
  • The main goal was to see if those who had thrombectomy had better recovery after 90 days compared to those who didn’t, along with checking if there were any serious side effects.

  • Posterior fossa tumors in adults are rare, accounting for 6% to 20% of all brain tumors, and their treatment is complex, necessitating this review of their clinical and surgical features.
  • A ten-year study analyzed 66 adult patients diagnosed and surgically treated for posterior fossa tumors, revealing a mean age of 63, with metastatic tumors being the most common type.
  • Symptoms typically included vegetative and cerebellar issues, and timely surgical intervention is essential for improving outcomes, with total tumor resection being the preferred option.

Background: A higher number of recanalization attempts reduces the efficacy of endovascular thrombectomy (EVT) for acute ischemic stroke secondary to large vessel occlusion (LVO). We assessed the impact of switching EVT techniques after a failed first pass on procedural and clinical outcomes.

Methods: This multicenter international study, conducted between January 2013 and December 2022, included patients undergoing EVT for anterior circulation LVO (internal carotid artery or M1 segments) with failed first pass recanalization.

Objective: Depression and anxiety are associated with poor outcomes following spine surgery. However, the influence of these conditions on achieving a minimal clinically important difference (MCID) following lumbar spine surgery, as well as the potential compounding effects of comorbid depression and anxiety, is not well understood. This study explores the impact of comorbid depression and anxiety on long-term clinical outcomes following surgical treatment for degenerative lumbar spondylolisthesis.

Hashimoto's encephalopathy (HE), a rare immune-mediated disorder, manifests as altered mental state, cognitive and psychological dysfunction, seizures, and myoclonus. Little is known, however, about the neuropsychological profiles of individuals with HE due to the sparse amount of research. This report overviews HE, summarizes findings from available published neuropsychological evaluations, and details neuropsychological examinations of a 57-year-old White woman with a confirmed HE diagnosis evidencing persistent neuropsychological impairment at two discrete timepoints.
