Cervical internal carotid artery tortuosity: A morphologic analysis of patients with acute ischemic stroke.
Article in Interventional neuroradiology : journal of peritherapeutic neuroradiology, surgical procedures and related neurosciences, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 19 papers.
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
background and purposeCervical internal carotid artery (ICA) tortuosity is thought to impede distal catheterization during attempted mechanical thrombectomy in patients with acute ischemic stroke. This study sought to assess the morphologic characteristics of ICAs and the effects of tortuosity on thrombectomy attempts.
methodsA retrospective review was completed of neck CTAs of patients with acute ischemic stroke due to a large vessel occlusion that underwent attempted endovascular recanalization. Significant tortuosity of ICAs was defined as the presence of kink(s) (acute (<90°) angulation), loop(s) (C- or S-shaped curvature with 2+ areas of acute (<90°) angulation), or coil(s) (full 360° turn arterial bend). Findings were statistically compared to procedure time, successful recanalization rate, patient demographics, and co-morbidities.
resultsOf 120 included patients, 47 (39.2%) had some form of tortuosity of one or both ICAs. Twenty-eight patients (23.3%) had a kink of one or both ICAs; this was followed in frequency by loops (n = 20; 16.7%) and coils (n = 8; 6.7%). Kinks were associated with lower rates of successful recanalization (p = 0.02). The presence of any tortuosity (kinks, loops, or coils) was not associated with number of passes during thrombectomy (p = 0.88), successful recanalization (p = 0.11), or total procedure time (p = 0.22). No association was noted between the presence of tortuosity and age (p = 0.96) or prior or current tobacco use (p = 0.75 and p = 0.69, respectively).
conclusionAmong patients referred for urgent revascularization for large vessel occlusion, approximately 40% exhibit some tortuosity. Kinks may portend lower likelihood of recanalization success, although tortuosity as a whole seems to have little effect on endovascular thrombectomy.
