[Intraluminal ultrasound echotomography: a new method in the study of arterial angioplasty. Evaluation of a case].

Intravascular ultrasound angioscopy allows to better define the structure of arterial wall and the effect of angioplasty. We report the case of a patient previously treated by coronary angioplasty, who underwent peripheral angioplasty for a stenosis of the left iliac artery. Intravascular ultrasound imaging performed before and after balloon dilatation clearly identified the plain of dissection and the partial resolution of the stenosis in a better way compared to digital angiography.
