RESUMO
BACKGROUND Coronary artery perforation is a rare complication of percutaneous coronary intervention for coronary artery occlusion. This report is of 2 cases of coronary artery perforation during percutaneous coronary intervention that were managed successfully using injection of combined Histoacryl (n-Butyl-2-Cyanoacrylate) and Lipiodol (ethiodized oil). CASE REPORT Case 1 was a 51-year-old man with a past medical history of hypertension, dyslipidemia, and multivessel coronary disease. He was admitted to our hospital with inferior wall myocardial infarction, and a stent was placed in the proximal right coronary artery. He also had chronic total occlusion (CTO) of the left anterior descending artery (LAD). The planned LAD CTO intervention was complicated by balloon-induced coronary perforation and was managed successfully with intracoronary injection of Histoacryl-Lipiodol mixtures via microcatheter. He was discharged in stable condition without any serious consequences. Case 2 was a 72-year-old man with underlying hypertension who was admitted to the hospital with diagnosis of unstable angina. The diagnostic angiography showed occlusion of the LAD, CTO of the left circumflex artery, and minor atherosclerosis in right coronary artery. A stent was placed in the mid-LAD without any complications. Subsequently, a planned left circumflex artery CTO intervention was complicated by wire-induced coronary perforation, which was treated successfully with injection of Histoacryl-Lipiodol mixture. The patient was discharged in good condition. CONCLUSIONS Histoacryl and Lipiodol injection was a rapid and effective management method in 2 rare cases of coronary artery perforation during percutaneous coronary intervention.
