Abstract “Arteries within the artery” is a particular image suggesting spontaneous recanalization after coronary thrombotic events in Kawasaki disease and it appears as multiple channels with highly echoic, thick divisions on intravascular ultrasound (IVUS) images. On the other hand, antiphospholipid syndrome (APS) can clinically manifest as arterial thrombosis, including coronary thrombotic events. We describe a 32-year-old male patient who presented with anteroseptal acute myocardial infarction (AMI) due to APS. Examination by IVUS revealed a multiple channel appearance similar to that of “arteries within the artery” associated with Kawasaki disease but low-echoic division in the non-culprit right coronary artery. We speculated that the multiple channel appearance was due to spontaneous recanalization after thrombotic events due to APS.
