A case report of broken tip of thrombus aspiration catheter (Thrombuster II) in ectatic left circumflex artery of young patient with Kawasaki disease

We describe a 29year old gentleman who presented with acute coronary syndrome, non-ST elevation myocardial infarction. Urgent percutaneous coronary intervention was performed in view of failed medical therapy (ongoing chest pain with dynamic ECG changes). In view of huge thrombus burden in ectatic left circumflex artery, we did thrombus aspiration by using thrombus aspiration catheter (Thrombuster II). After successfully aspirating thrombus, resistance felt on withdrawal of the aspiration catheter from the ectatic coronary artery. Tip of the thrombus aspiration catheter was broken and retained in the guide wire at the level of mid circumflex artery. The broken tip of thrombuster was successfully retrieved percutaneously. This case presents previously unreported complication of thrombus aspiration catheter (Thrombuster II). *Correspondence to: Mon Myat Oo, Cardiology Unit, Department of Medicine, University of Malaya Medical Centre, 59100 Kuala Lumpur, Malaysia, E-mail: myatoo@ummc.edu.my
