Direct Aspiration as First-Line Technique for Acute Intracranial Internal Carotid Artery Occlusion: Preliminary Results.
Article in Neurointervention, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeAcute 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
methodsData 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.
resultsOf 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).
conclusionADAPT exceeded other strategies for intracranial ICA occlusion as first-line technique, achieving faster recanalization and potentially impacting long-term functional outcome.
