Purpose: Acute intracranial internal carotid artery (ICA) occlusion has high clot burden and poor outcomes. No consensus exists on optimal first-line mechanical thrombectomy (MT) using direct aspiration first pass technique (ADAPT), stent retriever (SR) alone, or combined thrombectomy (non-ADAPT). We compared outcomes between ADAPT and non-ADAPT strategies for ICA occlusion. Materials and Methods: Data were collected from a comprehensive stroke center between January 2019 and August 2024. Patients with intracranial ICA occlusions were divided into ADAPT and non-ADAPT groups. Demographic, clinical, angiographic, and clinical outcomes (National Institute of Health Stroke Scale [NIHSS] score at 24 hours and modified Rankin Scale [mRS] score at 3 months) were compared. Good functional outcome was defined as a mRS score of 0–2. Results: Of 85 patients (mean age, 75 years; 47% females), 60 (70.6%) received ADAPT and 25 (29.4%) non-ADAPT (18 with aspiration and SR combined and 7 with SR alone). ADAPT achieved successful recanalization with shorter procedure time (median, 32 minutes vs. 60 minutes, P=0.001), higher modified Treatment In Cerebral Ischemia (mTICI) recanalization rates (final mTICI 2c-3, 75% vs. 52%; P=0.038; mTICI 2b-3, 98.3% vs. 88%; P=0.074), and better outcomes at 3 months (mRS ≤2, 47% vs. 22%; P=0.039). Multivariate analysis showed NIHSS at discharge as the only significant predictor of good functional outcome at 3 months (odds ratio [OR] 0.68, P<0.001), while ADAPT exhibited a trend toward significance (OR 5.10, P=0.075). Conclusion ADAPT exceeded other strategies for intracranial ICA occlusion as first-line technique, achieving faster recanalization and potentially impacting long-term functional outcome.

Background: and Purpose Stroke impairs cognition and movement. Although clinical severity and infarct volume can predict functional outcomes, variability in patient responses requires advanced structural and functional connectivity methods. Disconnection markers were tested to predict functional outcomes after acute ischemic stroke using diffusion tensor imaging. Methods: A probabilistic approach was used to quantify brain damage from white matter (WM) disconnections affecting cortical areas, using lesion masking on a tractography atlas and parcellation of gray matter into functional network nodes. Forty-three patients with acute ischemic stroke were grouped according to functional improvement (change in modified Rankin Scale score from 3–5 at discharge to 0–2 at 3-month follow-up). Significantly different structural disconnection measures between the groups were combined into a principal component and included in a logistic regression model to evaluate prediction accuracy. Fractional anisotropy (FA), radial diffusivity (RD), axial diffusivity, and mean diffusivity of the disconnected WM tracts were analyzed. Results: Baseline structural disconnections in the mid-posterior and central corpus callosum predicted poor functional outcomes at 3 months, and increased somatomotor network (SMN) disconnection severity correlated with poor recovery. Age, National Institutes of Health Stroke Scale score, and structural disconnections significantly predicted functional outcomes in logistic regression models. The first principal component analysis of the dysconnectivity measures explained 88% of the total variance and improved prediction accuracy from 53.8% to 76.9%. Differences in FA and RD in the region of interest of the corpus callosum between outcome groups were statistically significant. Conclusions Predictive outcome markers from probabilistic structural disconnection mapping in acute stroke emphasize preserving interhemispheric corpus callosum and SMN connections.

Arthroscopic meniscectomy of the knee is generally a safe and effective procedure with a low rate of vascular complications. We report here on a unique case of a 55-year-old man with a lateral inferior genicular artery pseudoaneurysm and a concomitant arteriovenous fistula that developed after arthroscopic meniscectomy; this was successfully treated with selective angiographic embolization. This case illustrates the effectiveness of an endovascular approach as a minimally invasive treatment for this uncommon complication that occurs after an arthroscopic procedure.
