“…IVUS is useful to identify intramural hematoma [5,9,10]. In our case, IVUS imaging also revealed the dissection into the media with extension into the medial space without reentry, and demonstrated a significant stenosis and obstruction of the distal LAD with a semilunar echo-dense intramural hematoma.…”

“…9,11,17 The echogenicity of blood depends on the flow rate, red cell aggregation, and fibrin content. 18 -20 Yamada et al 18 reported that the backscatter intensity of blood increased dramatically with stagnant flow.…”

“…Several cases of intra- or extra-mural hematomas after PCI have been reported, which were successfully treated with coronary stenting 2)11-13). In our case, the blood entry site appeared as a dissection within the media and adventitia and resulted in combined intra- and extra-mural hematomas as detected by IVUS, although there was no evidence of extravasation of contrast media into the pericardium by coronary angiogram.…”

“…Compared with an intramural hematoma, the incidence and mechanism of extramural hematomas are not well established. Mahr et al2) reported a case of an extramural hematoma causing a reduced distal vessel diameter after coronary stenting, which was treated with another coronary stent. Similar to the mechanism of an intramural hematoma, dissection into the adventitia plays a beginning point of blood entry, which can be detected by IVUS.…”
