Carotid Artery Plaque Rupture and Floating Thrombus Formation: A Case Study and Treatment

In summary, the CEUS diagnosis revealed a ruptured vulnerable plaque in the right carotid artery, leading to ulcer formation. Additionally, there was fibrous cap thickness (FFT) formation with moderate stenosis at the right internal carotid artery's origin. DSA, CTA, and MRA imaging confirmed moderate stenosis and a floating thrombus at the same location. The patient's MRI also showed acute lacunar infarction in the right caudate nucleus, linking the cerebrovascular event to plaque rupture and thrombus formation. To address this, a neurologist performed a procedure involving stent placement and balloon angioplasty. This was done after placing a protective umbrella in the distal end of the patient's FFT in the carotid artery. Post-surgery, the patient experienced no new neurological symptoms and was discharged following condition improvement.
