RESUMO
Percutaneous transluminal coronary angioplasty(PTCA) has been widely applied in patients with coronary artery disease since 1977. Although coronary angioplasty has beeb shown to be safe and effective treatment strategy, acute closure & restenosis remain as major limitations of PTCA. Acute occlusion due to intracoronary thrombus accumulation during or immediately after coronary angioplasty is serious complication of PTCA, also, Intracoronary urokinase has been used to treat acute occlusion by intracoronary thrombus that complicated in PTCA and proved to be effective in restoring vessel preventing acute myocardial infarction. We report a case in which embolism of left anterior descending artery was complicated during angioplasty of left circumflex artery and managed with intracoronary infusion of urokinas.
