Catheter-induced in-stented segment coronary dissection

Coronary angiography can lead to different kinds of complications. Catheter-induced coronary dissection is one of the most feared of them. It is uncommonly reported and may result in ischemic events ranging from angina to death. We report a case of a woman admitted to the hospital due to progressive effort angina who had a complication during percutaneous coronary intervention not previously reported. It is a usual thinking that a coronary artery stented segment would not be prone to dissect either spontaneously or catheter-induced. This report describes a catheter-induced in-stented segment coronary dissection and a discussion if the dissection line involving the left anterior descending coronary artery stented segment occurred between the stent and the intimal hyperplasia or between the stent and the adventitia.
