ABSTRACT

Diagnosis: Carotid artery stenosis secondary to atherosclerotic disease. Based on an ICA PSV of 315, degree of stenosis is most likely greater than 70%.

History: Asymptomatic. Patient presents for routine wellness visit. Past medical history significant for diabetes mellitus and dialysis dependent ESRD

Findings: Gray scale and color Doppler images demonstrate a large echogenic lesion with posterior shadowing which greatly narrows the lumen of the proximal right internal carotid artery at the level of the carotid bifurcation. Spectral Doppler images demonstrate increased peak systolic velocity to 315 cm/sec in the region of the lesion with loss of the acoustic window and spectral broadening. The ICA/CCA PSV ratio is 3.79.

Ddx: Atherosclerotic carotid artery disease Carotid vasculitis (very unlikely given the patient's history and the echotextures of the plaques)

Dxhow: The location of the lesion and the heterogenous echotexture characteristics of the lesion are diagnostic of atherosclerotic plaque.

Exam: Audible bruit over right carotid artery system.

No MeSH data available.


Longitudinal gray-scale ultrasound image at the level of the right carotid bulb demonstrates a lesion with heterogeneous echotexture, an echogenic component anteriorly, and posterior acoustic shadowing.
