Background: The best management of carotid artery dissection (CAD) is still controversial ranging from antiplatelet medication to open surgery or endovascular treatment. In this retrospective study, we assessed the safety and efficacy of endovascular stent angioplasty for the treatment of CAD.
Methods: From February 2006 to February 2016, 44 patients (28 women and 16 men, age range 25-65 years, mean 42) with CAD were included in this study. The internal carotid artery dissection was spontaneous in 32 patients and posttraumatic in the remaining 12 (in 1 case, it was bilateral). Twenty-eight patients were treated by intravenous heparin infusion followed by standard oral anticoagulation. Carotid artery stenting was carried out in 14 cases with recurrent ischemic events despite optimal anticoagulation management. Two patients with an open trauma of the neck were submitted to a common carotid to internal carotid bypass (CC-CI bypass). The follow-up ranged from 6 to 60 months and was performed clinically first and with Doppler ultrasound and computed tomography or magnetic resonance at 6, 12, and 24 months.
Results: Follow-up ranged from 6 to 60 months. Mortality was nil. All patients submitted to the endovascular or surgical management had an immediate relief of their neurologic symptoms with no procedure-related complications. No thrombosis or restenosis of the CC-CI bypass or of carotid artery stents occurred during intraoperative and postoperative period and follow-up.
Conclusion: An alternative therapeutic option is mandatory in a subset of patients regarded as being at high risk for stroke because anticoagulant therapy was either contraindicated or failed clinically with recurrent transient ischemic attacks/transient symptoms associated with brain infarction. In these selected cases, endovascular stent placement seems to be a safe and effective option to restore vessel lumen integrity and prevent stroke.
