IVUS is valuable for diagnosing unusual angiographic results such as extramural vessel wall hematoma after coronary stenting, which can be successfully treated with further stent implantation.
May support IVUS use in rare post-stenting hematomas; leaves open prospective validation before broader adoption.
An extramural vessel wall hematoma occurred immediately after implanting a coronary stent in an in-stent-restenosis of the intermedius branch. Angiography showed a significant luminal reduction distal to the intervention site. Intravascular ultrasound revealed an extramural echolucent zone compressing the vessel lumen. Stent implantation compressed the hematoma and allowed adequate myocardial perfusion. This demonstrates the value of intravascular ultrasound (IVUS) in cases of unusual angiographic results which can help to manage complications after coronary intervention.
