BackgroundCoronary pseudoaneurysm (CPA) are associated with iatrogenic coronary artery dissection or perforation, which rarely reported formation early after percutaneous coronary intervention (PCI) for chronic total occlusion (CTO). This study reported a case of CPA that developed 4 weeks after PCI for CTO.Case ReportA 40-year-old man was admitted with unstable angina and diagnosed with CTO of the left anterior descending artery (LAD) and right coronary artery. The CTO of the LAD was successfully treated by PCI. However, reexamination by coronary arteriography and optical coherence tomography after 4 weeks confirmed a CPA at the stented middle segment of the LAD. The CPA was treated surgically by the implantation of a Polytetrafluoroethylene-coated stent. reexamination at the 5-month follow-up revealed a patent stent in the LAD and no CPA-like manifestations. Intravascular ultrasound showed no intimal hyperplasia or in-stent thrombogenesis.ConclusionCPA might develop within weeks after PCI for CTO. While it could be successfully treated by the implantation of a Polytetrafluoroethylene-coated stent.Copyright © 2023 the Author(s). Published by Wolters Kluwer Health, Inc.
