[Carotid loops and folds, one of the limitations of the Doppler examination (author's transl)].
Lesions in the form of loops and folds occur frequently in carotid pathology. Different authors have assessed their responsibility for the occurrence of ischaemic cerebral accidents at between 20% and 16%. Diagnosis of the condition by Doppler exploration of such abnormal cases is certainly of value, but is subject to numerous sources of error. The present authors have defined the different types of lesions, their pathogenic aetiology and their repercussions on the blood indices. The various changes occurring in Doppler tracings have been discussed in relation to these anatomical types of carotid lesions and in relation to the arteriographic pictures.
