"Pseudo" intramural injection following percutaneous transluminal angioplasty.
An angiographic appearance of "pseudo" intramural injection is commonly produced following intraluminal balloon dilatation resulting from the dehiscence of the atheromatous intima that is an unavoidable consequence, and not a complication of angioplasty. These angioplasty-induced changes differ from true intramural dissections in that they are confined to the dilatation site and do not extend beyond this area.
