From: Takayasu’s arteritis: a case with relapse after urgent coronary revascularization
After successful left main stem stenting, intravascular sonography was performed with a coronary guide wire in the left anterior descending artery. This intravascular sonographic view depicts several hypoechogenicities in the vessel wall of the proximal left anterior descending artery (arrowheads). In other frames, there was very prominent thickening of the intima in this coronary segment. One example is given as Additional file 2
