Background and Purpose: Internal carotid artery dissection (ICAD) is relatively rare in Japan. We investigated the characteristics of ICAD patients after non-hemorrhagic onset in our department. Methods: We reviewed and analyzed the clinical records of 16 patients (18 lesions) treated between January 2011 and December 2017. We analyzed the background and treatment methods, complications, clinical course and outcome of 16 patients. Results: Patient age was ranged from 20 to 72 years (average, 48.5 years). Fifteen patients were male (93.8%). Fifteen lesions located on the extracranial and 3 lesions located on the intracranial. Nine lesions were cerebral infarction onset and 7 lesions were headache and neck pain onset, 2 lesions were incidental. Nine lesions were performed only medical treatment and 9 lesions underwent endovascular treatment. Medical treatment was blood pressure management and antithrombotic therapy, and in all cases of endovascular treatment, the stent placement was made in the dissection part. In the course after treatment, good outcome [modified Rankin Scale (mRS): 0–2] were 13 patients and poor outcome [mRS: 3–6] were 3 patients. Conclusion: Depending on the case, 9 patients who underwent intravascular treatment for cases of acute occlusion and symptoms worsening obtained relatively good outcome.
