Intramural collection caused by contrast extravasation into the ascending aortic wall.


ABSTRACT: Cardiac catheterization is a procedure routinely performed worldwide, with an estimated amount of 61,000 coronary angioplasties performed in the UK annually. Associated mortality--in the region of 0.1-0.2%--is minimal and complication rate approximately 1.5%. The most serious complications described are embolic stroke, cardiac chamber perforation, aortic dissection, coronary occlusions or dissection, and major peripheral vascular complications, including retroperitoneal haematoma and life-threatening haemorrhage. We report the case of a 75-year old patient who had inadvertent contrast agent injection into the aortic wall, leading to a localized contrast collection within the tunica media. This complication has been described before but only in association with coronary artery dissection. It is important to diagnose and manage such a situation, as most iodinated intravascular contrast agents exert a high osmotic load and thereby lead to tissue oedema and necrosis on extravasation. We describe the management of the case and discuss relevant therapeutic strategies.
