Abstract

Background: Definitive treatment of carotid dissection-related strokes is currently unproved. The best endovascular technique in this setting remains to be established. Objective: To report our experience in endovascular treatment of internal carotid artery dissection presenting with acute strokes. Methods: Consecutive patients with acute strokes due to internal carotid artery dissection treated with endovascular therapy at our hospital between January 2008 and July 2019 were included. Patients were assigned to endovascular treatment according to clinical-radiologic mismatch, NIHSS greater than or equal to 5, and within 6 hours after symptom onset. The endovascular technique is described. Intracranial recanalization, carotid dilatation, and clinical outcomes were retrospectively analyzed. Results: Seven patients met the inclusion criteria. The mean age was 55 years; 5 patients (71.4%) were male. 71.4% had tandem occlusion strokes, while 28.6% had hemodynamic strokes. The mean onset-to-puncture time was 3.92 hours. Stent-assisted angioplasty for internal carotid artery was done for 85.7% of patients with a mean of 1.6 deployed stents. Dilatation was successful in 83.3% of them. Successful overall recanalization rate was 85.7%. No major complications were encountered. Minor complications occurred in 42.8% of cases. The mean NIHSS score decreased from 13.7 preoperative to 5 after 3 days. Good functional outcome (mRS 0-2) was found in 85.7% of patients at 3 months. No recurrent strokes identified over an average of 40.86 months follow-up. Conclusion: Our study provides evidence that endovascular therapy for internal carotid artery dissection-related strokes has high rates of reperfusion and favorable outcomes. Stent-assisted angioplasty of carotid dissection is thought to be safe and effective.
