Bilateral Carotid Artery Examination: The internal and external diameters of the bilateral common carotid and carotid arteries are normal. The intima of the bilateral carotid arteries is locally thickened and rough, with the intima-media thickness being approximately 1.4mm (right) and 1.3mm (left). There are several plaques on the walls of the bilateral carotid arteries, one of which is approximately 4.1×1.5mm (right) and 2.6×1.3mm (left). CDFI: No abnormal blood flow signals are observed, PW: No abnormal spectral patterns are observed.
Bilateral Vertebral Artery Examination: The course of the bilateral vertebral arteries is normal, with no obvious stenosis or typical plaque echoes on the walls. CDFI: The blood flow in the bilateral vertebral arteries is good, PW: No increase in resistance index.
