Patient description: A 46-year-old man presents with dizziness and frequent headaches. He has a family history of CAD, but no other cardiovascular risk factors such as smoking, high blood pressure, and diabetes mellitus and is physically active. The patient's LDL-C and HDL-C levels were 545 and 53 mg/dL, respectively. His fasting glucose and triglyceride levels (85 and 158 mg/dL, resp.) were within normal limits. The patient reported no use of lipid-lowering medications. Neck auscultation revealed a systolic murmur 3+/6+ in the neck, radiating to the skull. Ultrasonography of the carotid arteries, revealed severe stenosis in the left internal carotid artery (LICA), as well as moderate stenosis in the right internal carotid artery (RICA) estimated between 40% and 50%. For the LICA, the peak-systolic (PSV) and end-diastolic velocity (EDV) cutoff values were 208.5 cm/s and 54.5 cm/s, respectively; RICA PSV was 91.72 cm/s and RICA EDV was 37.37 cm/s. Plaque was observed in the anterior and posterior walls of the internal carotid artery and common carotid artery, which were characterized as bulky plates extending to the middle third of the internal coronary arteries (ICAs) and as predominantly echogenic and hyperechoic, with less than 50% of the area being echolucent with uneven surfaces.
