64-slice computed tomography as an adjunct to aortography in suspected iatrogenic aortocoronary dissection

摘要

latrogenic aortic dissection is an uncommon but potentially fatal complication. We present a case of iatrogenic coronary dissection following percutaneous coronary intervention to the right coronary artery. Aortography initially suggested coronary dissection complicated by type A aortic dissection, however, 64-slice computed tomography excluded classical aortic dissection and instead demonstrated widespread pericardial extravasation secondary to coronary perforation/rupture. This article reviews the pathophysiology, diagnosis and management of aorto-coronary dissection.
