Intermittent dizziness due to a diaphragm of the common carotid artery successfully treated by stenting.

Carotid diaphragm is considered a form of fibromuscular dysplasia (FMD) that may result in the narrowing of blood vessels, potentially increasing the risk of stroke. More than 50 cases of carotid diaphragm have been reported, most cases of which are located in the internal carotid artery. Patients are usually middle-aged and initially manifest as syncope, tinnitus, and ischemic stroke. In this paper, we report a rare case of septal aneurysm in the common carotid artery (CCA). This is the fourth case reported in the literature.
