A 90-year-old women died with acute peritonitis. After she died, the coronary artery was imaged by intravascular ultrasound (IVUS) (Atlantis SR Pro, 40 MHz, Boston Scientific, Natick, Massachusetts). IVUS visualized a small tubular, low-echoic structure exterior to media (Fig. 1A, arrowhead). Histology confirmed vasa vasorum formation in the corresponding sections (Figs. 1B and 1C).
The vasa vasorum of the coronary artery is a network of small blood vessels that supply coronary vessel wall and is known as 1 of the morphological characteristics of vulnerable plaque. The majority of vasa vasorum arises from the adventitia and penetrates the outer side of the coronary plaque. In general, the depth in IVUS images is around 8 to 10 mm and, therefore, is sufficient for visualizing vasa vasorum. The size of the vasa vasorum varies widely and IVUS could detect several hundred micrometers of the vasa vasorum as a tubular, low-echoic structure at the outer side of the coronary plaque.
