Intracoronary urokinase was used to treat flow-limiting intracoronary thrombus accumulation that complicated successful percutaneous transluminal coronary angioplasty (PTCA) during acute ischemic syndromes in 48 patients who were followed up through the acute phase of their illness. The study group with 63% of all patients studied before discharge), and in no patient was there angiographic evidence of reocclusion, although two patients showed angiographic evidence of stenosis; improved vessel percent stenosis persisted, averaging 32±17%. In all patients studied, the coronary flow was TIMI grade 3 at follow-up. Thus, in patients with acute ischemic syndromes with flow-limiting intracoronary thrombus accumulation that complicated PTCA, intracoronary urokinase with repeated PTCA proved to be highly effective in restoring vessel patency and avoiding early complications.
