title: Spontaneous disappearance of coronary pseudoaneurysm due to coronary artery perforation following percutaneous coronary intervention.
abstract: In recent years, while therapeutic outcome after percutaneous coronary intervention is improving due to the introduction of drug-eluting stent and device development, procedure-related complications including coronary perforation may ineluctably occur though at low-frequency, even if careful manipulations are performed under IVUS guidance. Meanwhile, coronary pseudoaneurysm subsequent to coronary perforation is one of the complications at chronic phase infrequently experienced following percutaneous coronary intervention. To date, the incidence and natural history of pseudoaneurysm following coronary artery perforation remain unclear. We experienced a case with coronary pseudoaneurysm developed 2 weeks after Ellis II-type coronary artery perforation which spontaneously disappeared 4 months later. As the mechanism of disappearance, thrombotic occlusion was confirmed upon intravascular ultrasound.
