摘　　要：BACKGROUND In the development of coronary stent technology,bioresorbable scaffolds are promising milestones in improving the clinical treatment of coronary artery disease.The“leave nothing behind”motto is the premise of the fourth revolution in percutaneous coronary intervention(PCI).Studies proving the safety and efficacy of the magnesium-based resorbable scaffolds(MgBRSs)include the BIOSOLVE-I and BIOSOLVE-II trials and the latest BIOSOLVE-IV registry.However,spontaneous retrograde dissection of a partially absorbed MgBRS may still occur,albeit rarely.CASE SUMMARY We describe an unusual case of coronary artery disease in a patient who had undergone a successful PCI 8 mo earlier,where an MgBRS was implanted into the left anterior descending artery(LAD)and left circumflex artery with drug-coated balloons for a ramus intermedius branch stenosis to achieve the“leave nothing behind”therapeutic intention and was currently presenting with a gradual worsening of chest tightness.The distal edge vascular response,during subsequent attempts with balloon angioplasty was performed smoothly.However,spontaneous retrograde dissection of a partially absorbed MgBRS in the LAD ensued.Successful bailout stenting was performed with revascularization of the entry and exit sites created by spontaneous dissection and complete sealing of the intramural hematoma.The patient recovered well and was discharged after 2 d of intervention.When followed up in August 2020(7 mo later),the patient showed uneventful recovery.CONCLUSION Spontaneous retrograde dissection of a partially absorbed MgBRS was successfully treated using bailout sirolimus-eluting coronary stent strategy.
