The B-mode ultrasound showed an enlarged thickened medio-adventitial echostructure with a slightly heterogeneous and iso or hypoechoic appearance. There was no narrowing. Injection of ultrasound contrast led to significant enhancement in the wall reflecting neovascularization secondary to inflammation. Other imaging methods (MR and CT angiography) found no abnormality. At the 3-month follow-up visit, the surface area of the lesions was greatly decreased and the ultrasound contrast enhancement had disappeared. These two cases illustrate how focal lesions of the carotid wall missed on MR and CT angiography can be detected and visualized with B-mode ultrasound contrast enhancement. Contrast enhanced ultrasound leads to the concept of "active lesions" resulting from inflammatory processes that can be read...

The French Cardiology Society vascular group turned its attention to arteries, veins, hypertension and a more fundamental investigation to analyse the results from some illuminating studies which appeared in 2004, despite some pertinent therapeutic doubts. Examination of the trials discussed here shows the importance, as much in vascular pathology as elsewhere, of founding our practice on evidence based medicine.

The objective was to evaluate interobserver and intraobserver agreement in characterizing the carotid plaques studied by both B mode imaging and color Doppler imaging, which is the only ultrasonic method available for recognizing anechoic lesions. Fifty-three carotid plaques greater than 40% in diameter were selected from four centers and simultaneously analyzed by 9 observers. Five types of plaques were defined by their echo structure: class I = uniformly anechogenic, class II = predominantly hypoechogenic with >50% hypoechogenic area, class III = predominantly echogenic with >50% echogenic area, class IV uniformly echogenic, class V = unclassified plaques. The luminal surface was characterized as either 1 = regular, 2 = recess of more than 2 mm in depth and width, or 3 = unclassified. Agreement of these variables was calculated by using the kappa index, agreement proportion and an intraclass correlation coefficient. Interobserver reproducibility was only fair for type I (kappa = 0.47) and for the luminal surface (class 1, kappa = 0.52 and class 2, kappa = 0.41). Agreement proportion was 0.51 in hypoechoic plaques and 0.64 in the determination of the regular surface. Mean intraobserver agreement was fair (kappa = 0.47 +/- 0. 1) for plaque echogenicity to good (kappa = 0.63 +/- 0.19) for surface. This study shows that the semiquantitative classification, first developed by Gray-Weale, then by Nicolaides, could be improved, thus giving rise to a new outlook in the debated field of ulcerations.

Recommendations are the following if the degree of the stenosis and the precise location of the stenosis are well defined. Ultrasonic Doppler duplex methods describe the composition and the surface topography of carotid plaques. Echogenicity (from anechoic
