Journal of Neurointervention and Stroke (JNeViS) is a peer-reviewed journal dedicated to publishing clinical, epidemiological, basic science, and translational research in vascular and interventional neurology. The journal also welcomes contributions on other neurological and neurosurgical conditions that may benefit from minimally invasive and innovative approaches across specialties such as Neurology, Radiology, and Neurosurgery. Suitable submissions for this Journal include Original Article (observational studies, clinical trials, epidemiological research, health services and outcomes studies, basic and translational research, and innovative techniques in vascular and interventional neurology), and Case Reports or Case Series.

Abstract

Highlight: Radiation dose declined progressively during early neurointerventional training Radiation dose has a clearer temporal trend than fluoroscopy time in early training ABSTRACT Introduction: Radiation safety is a fundamental component of neurointerventional practice and competency-based fellowship training. While fluoroscopy time has traditionally been used as a surrogate marker of procedural efficiency, it may not accurately reflect total radiation exposure. Dose-related metrics may better represent technical maturation and radiation-conscious procedural behavior during fellowship progression. Objective: This study compared fluoroscopy time and radiation dose to characterize the early learning curve of neurointerventional fellowship training. Method: This retrospective observational study analyzed 108 consecutive DSA-based brain angiograms performed during the first six months of a supervised fellowship. Chronological case-sequence linear regression was employed to evaluate longitudinal changes in radiation dose and fluoroscopy time. Result: The mean fluoroscopic radiation dose decreased by 42.8%, dropping from 170.17 mGy in month 1 to 97.36 mGy in month 6. Linear regression revealed a significant negative association between case sequence and radiation dose (B = -0.468 mGy/case; p = 0.012; R2 = 0.058). In contrast, fluoroscopy time showed only modest fluctuations and no significant linear association (p = 0.780). Conclusion: During early fellowship training, fluoroscopic radiation dose demonstrates a clearer temporal trend than fluoroscopy time, suggesting it is a more informative marker of procedural maturation. However, the low explanatory power and the absence of adjustment for procedural complexity require cautious interpretation. These findings warrant further research incorporating complexity-adjusted designs to better define technical maturation.

Abstract

Highlight: Primary hypertensive ICH is the most common etiology of ICH in our study Primary ICH has a higher admission ICH score than secondary ICH Elevated admission BP is associated with higher ICH severity ABSTRACT Introduction: Intracerebral hemorrhage (ICH) is a stroke subtype associated with a high case-fatality rate despite being less prevalent than ischemic stroke. Spontaneous ICH is broadly classified into primary and secondary etiologies, yet clinical evidence remains conflicting regarding which group presents with greater initial severity. Objective: To compare admission ICH scores between primary hypertensive and secondary vascular ICH. Method: This retrospective study included adults with non-traumatic ICH who presented within 48 hours at an Indonesian stroke center. All patients underwent cross-sectional imaging and angiography; those with coagulopathy, anticoagulant use, or recurrent strokes were excluded. The primary outcome was clinical severity, dichotomized using an admission ICH score of ≥3 versus <3. Bivariate tests and multivariate logistic regression were used to identify independent predictors of high severity. Result: Of the 306 patients analyzed, 267 (87.25%) were diagnosed with primary ICH and 39 (12.75%) with secondary ICH. Secondary etiologies included ruptured arteriovenous malformations (n=21), intracranial aneurysms (n=16), and dural arteriovenous fistula (n=2). Patients with primary ICH were significantly older and exhibited higher admission blood pressure and more frequent infratentorial hematoma locations. Conversely, those in the secondary ICH group were typically younger and more likely to present with seizures or concomitant subarachnoid hemorrhage. Primary ICH was independently associated with greater clinical severity, as indicated by an admission ICH score of ≥3 (29.59% vs 7.69%; aOR 5.04, 95% CI 1.51–16.86, p=0.009). Conclusion: Primary ICH exhibits higher admission severity than secondary ICH. Prospective research is required to evaluate long-term functional outcomes.
