title: Pseudo-lesion of internal mammary artery graft and left anterior descending artery during percutaneous transluminal angioplasty--a case report.
abstract: New lesions appearing during coronary angioplasty may be due to spasms, dissection, and thrombosis. Straightening of the tortuous vessels by guidewire may produce transient angiographic pseudo-lesions, which mimic severe artery damage. An additional case is reported, in which simultaneous artifactual lesions involved the internal mammary artery and the left anterior descending coronary artery, mimicking thrombosis and dissection. Recognition of this entity is essential to avoid unnecessary interventions and potentially harmful complications.
