Purpose/aim: This study aims to compare efficacy and safety of Low-profile Visualized Intraluminal Support (LVIS) stent and Pipeline Embolization Device (PED)-assisted endovascular interventions in patients with middle cerebral arterial aneurysms.
Materials And Methods: This retrospective study included a total of 144 MCA patients, who went to our hospital from January 2013 to December 2017. These patients were divided into two groups: LVIS group, 81 cases; PED group, 63 cases. Then, the basic clinical characteristics were collected. The Raymond grade was used to evaluate the embolism immediately after the surgery and at six months after surgery. The Glasgow Outcome Scale (GOS) and modified Rankin scale were used at six months after surgery, and the recurrence rate was also recorded.
Results: The mean aneurysm diameter was 7.7 ± 5.1, which range from 2-25 mm. There were 25 cases with ruptured aneurysms. The results revealed that 57 (70.4%) cases in the LVIS group and 41 (65.1%) cases in the PED group presented with complete embolisms immediately after the surgery. The mean GOS score after six months was 4.6 ± 0.9 in the LVIS group and 4.6 ± 0.9 in the PED group. Furthermore, a total of 86.4% cases had a good prognosis in the LVIS group, while 87.3% cases had a good prognosis in the PED group. Moreover, recurrence was found in six (7.4%) cases in the LVIS group and in five (7.9%) cases in the PED group.
Conclusion: Both these two methods are effective and safe, with a high good prognosis rate and low recurrence. However, there was no significant difference between the PED and LVIS stent methods.

Three-dimensional spatial distribution of lumbar paraspinal intramuscular fat revealed by spatial parametric mapping.
Eur Spine J

Department of Computer Engineering and Software Engineering, Polytechnique Montreal, Montreal, Canada.
Purpose: Lumbar paraspinal intramuscular fat (IMF) has emerged as a biological factor in low back pain (LBP). Traditional assessments measure IMF across the entire muscle or at specific levels and may miss key information on the role of IMF in LBP. Despite known variations across the lumbar spine, the three-dimensional (3D) distribution of IMF has not been characterized across people.

Article Synopsis
- The study compares the safety and efficacy of two stent types, LVIS and Enterprise, in treating ruptured intracranial aneurysms (RIA) using data from 231 patients admitted between 2018 and 2021.
- Before adjusting for other variables, Enterprise showed a higher rate of poor prognosis after 12 months compared to LVIS.
- After thorough analysis, the LVIS group had a significantly lower occurrence of delayed cerebral ischemia (DCI) compared to the Enterprise group, suggesting similar overall efficacy but differing risks for complications.*
Short-Term Impact of Seizures and Mitigation Opportunities.
Curr Neurol Neurosci Rep
August 2024
Neurelis, Inc, San Diego, CA, USA.
Purpose Of Review: The burden of epilepsy is complex and consists of elements directly related to acute seizures as well as those associated with living with a chronic neurologic disorder. The purpose of this systematic review was to characterize short-term burdens of seizures and to explore the potential value of acute treatments to mitigate these burdens apart from reducing the risk of status epilepticus.
Recent Findings: A systematic literature search was conducted using PubMed to identify articles published from January 1, 2017, to June 22, 2023, that described short-term burdens and acute treatments of seizures.
Use of the Neuroform Atlas Stent or LVIS Jr Stent for Treatment of Unruptured Intracranial Aneurysms in Parent Arteries of <2 mm in Diameter: A Multicenter Experience.

Background And Purpose: The Neuroform Atlas stent and the LVIS Jr stent are intracranial microstent systems for the treatment of wide-neck intracranial aneurysms. Hence, this study aimed to compare the efficacy and safety of the Neuroform Atlas stent and the LVIS Jr stent for the treatment of unruptured intracranial aneurysms in parent arteries of <2 mm in diameter.
Materials And Methods: From March 2022 to April 2023, the clinical and imaging data of 135 patients with unruptured intracranial aneurysms treated with stent-assisted coiling using the Neuroform Atlas or LVIS Jr stent in parent arteries of <2 mm in diameter were retrospectively analyzed.
Vasoactive Management of Pulmonary Hypertension and Ventricular Dysfunction in Neonates Following Complicated Monochorionic Twin Pregnancies: A Single-Center Experience.

Objectives: Twins resulting from a complicated monochorionic (MC) twin pregnancy are at risk for postnatal evolution of pulmonary hypertension (PH) and cardiac dysfunction (CD). Both pathologies are important contributors to short- and long-term morbidity in these infants. The aim of the present retrospective single-center cohort study was to evaluate the need for vasoactive treatment for PH and CD in these neonates.
