Endovascular treatment of a basilar artery dissecting aneurysm

basilar artery (ba) dissecting aneurysms pose difficulties to treatment because both bleeding and thrombosis can happen in the same patient, clinical course is unpredictable and high morbidity is usual. we report the case of a 37-year-old woman with a ba aneurysm probably caused by arterial dissection, presenting embolic and hemorrhagic complications. the aneurysm was submitted to endovascular treatment with stenting and coil embolization. clinical and radiological results were excellent and no complications were observed, suggesting that ba stenting and coil embolization may be a safe and effective treatment for this condition.
