What is Cervical internal carotid artery tortuosity: A morphologic analysis of patients with acute ischemic stroke about?

## Background and purpose: Cervical 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. ## Methods: A 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. ## Results: Of 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
