Background And Purpose: Symptomatic intracranial hemorrhage (sICH), potentially associated with poor prognosis, is a major complication of endovascular thrombectomy (EVT) for ischemic stroke patients. We aimed to develop and validate a risk model for predicting sICH after EVT in Chinese patients due to large-artery occlusions in the anterior circulation.
Methods: The derivation cohort recruited patients with EVT from the Endovascular Treatment for Acute Anterior Circulation Ischemic Stroke Registry in China. sICH was diagnosed according to the Heidelberg Bleeding Classification within 24 hours of EVT. Stepwise logistic regression was performed to derive the predictive model. The discrimination and calibration of the risk model were assessed using the C index and the calibration plot. An additional cohort of 503 patients from 2 stroke centers was prospectively enrolled to validate the new model.
Results: We enrolled 629 patients who underwent EVT as the derivation cohort, among whom 87 developed sICH (13.8%). In the multivariate adjustment, Alberta Stroke Program Early CT Score (odds ratio [OR], 0.85; =0.005), baseline glucose (OR, 1.13; =0.001), poor collateral circulation (OR, 3.06; =0.001), passes with retriever (OR, 1.52; =0.001), and onset-to-groin puncture time (OR, 1.79; =0.024) were independent factors of sICH and were incorporated as the Alberta Stroke Program Early CT Score, Baseline Glucose, Poor Collateral Circulation, Passes With Retriever, and Onset-to-Groin Puncture Time (ASIAN) score. The ASIAN score demonstrated good discrimination in the derivation cohort (C index, 0.771 [95% CI, 0.716-0.826]), as well as the validation cohort (C index, 0.758 [95% CI, 0.691-0.825]).
Conclusions: The ASIAN score reliably predicts the risk of sICH in Chinese ischemic stroke patients treated by EVT.

Background: Radiation-induced sarcoma (RIS) is an exceptionally rare occurrence following radiation therapy, and manifestation usually occurs after a several-year latency period. Herein, the authors report the development of a radiation-induced osteosarcoma of the frontoparietal calvaria following treatment for an oligodendroglioma in an 84-year-old woman.
Observations: The patient had been diagnosed with a grade III anaplastic oligodendroglioma when she was 78 years old.

Background And Objectives: Although previous trials have established the efficacy and safety of endovascular thrombectomy (EVT) in large ischemic core strokes, most of them excluded patients with extracranial internal carotid artery (e-ICA) occlusion. We aimed to compare outcomes in patients with e-ICA occlusion and large ischemic core infarcts treated with EVT vs medical management (MM).
Methods: This was a secondary analysis of the SELECT2 trial, a randomized controlled trial conducted at 31 international sites.

Background: Acute ischemic stroke treatment typically involves tissue-type plasminogen activator (tPA) or tenecteplase, but about 50% of patients do not achieve successful reperfusion. The causes of tPA resistance, influenced by thrombus composition and timing, are not fully clear. Neutrophil extracellular traps (NETs), associated with poor outcomes and reperfusion resistance, contribute to thrombosis.

Background: Sex-specific differences in stroke risk factors, clinical presentation, and outcomes are well documented. However, little is known about real-world differences in transient ischemic attack (TIA) hospitalizations and outcomes between men and women.
Methods: This was a retrospective cohort study of the 2016 to 2021 Nationwide Readmissions Database in the United States.
