[Endovascular stent-assisted angioplasty after cervical arteries dissection]. / Angioplastie-stenting transluminale percutanée après dissection des troncs supra-aortiques.

INTRODUCTION: Spontaneous dissection of cervical arteries is one of the major causes of stroke in young patients. The recommended treatment is curative anticoagulation. However, in selected cases, this treatment could fail or meet contraindications. In such cases, an endovascular stent-assisted angioplasty could be successful. CASE REPORT: We report the case of a 47-year-old patient with spontaneous dissection of the carotid and vertebral arteries. Despite optimized anticoagulant therapy, cerebral perfusion was low. An endovascular stent-assisted angioplasty was performed in the intra- and extracranial segments of the right internal carotid artery. Consequently by improving the intracranial circulation, normal functioning was restored with no immediate complications and the patient remained free of complications at 16-month follow-up. CONCLUSION: Dissections of cervical arteries that lead to a chronic reduction in brain perfusion might benefit from endovascular stent-assisted angioplasty.
