Endovascular stent placement for cervical internal carotid artery aneurysmcausing cerebral embolism: Usefulness of neuroradiological evaluation

We present a case of a cervical internal carotid artery aneurysm that cause d cerebral embolism. This lesion was supposed to be a dissecting aneurysm d ue to blunt neck injury. The large aneurysm with intramural thrombus was tr eated with endovascular placement of a balloon-expandable stent. Both CT an d MRI were useful for evaluating the size and characteristics of the aneury smal wall. Intravascular ultrasound imaging was also useful for evaluation of the satisfactory stent deployment and identification of the neck of the aneurysm. We disscuss effectiveness of endovascular stenting for cervical i nternal carotid artery aneurysm with intramural thrombus and the usefulness of a combination of the neuroradiological imaging before, during and after the interventional procedure.
