title: [Coronary angioplasty immediately after intracoronary thrombolysis during the acute phase of myocardial infarction].
abstract: Since the introduction of intracoronary thrombolysis in the acute phase of myocardial infarction, all workers have observed a high incidence of coronary reocclusion (about 20%) essentially in the first hours and days after coronary recanalisation (CR). This had led to some groups carrying out transluminal coronary angioplasty (TCA) at the same time as CR by thrombolysis in situ to treat significant residual postthrombolysis stenosis. This french multicentre study carried out in 5 centres concerned 9 men (average age: 46.1 years) with 5 anterior infarcts (total thrombosis of the LAD artery) and 4 inferior infarcts (total thrombosis of the right coronary artery-RCA). Intracoronary trinitrate was ineffective in relieving the occlusion in all cases. In 5 cases, the thrombolytic protocol was streptokinase (SK) 3 000 u/min for 60 minutes; in the other 4 cases, the plasminogen-urokinase (Pg-UK) protocol was used. Thrombolysis was successful in all 9 cases. The results of TCA performed at the same time were also good (8/9 successes; 4 LAD and 4 RCA) without any complications during the procedure. There was only one immediate post-TCA reocclusion on a LAD artery. In all cases the initial ECG appearances of infarction remained, CR only appearing to prevent extension of the necrosis. The successful results of CR + TCA were maintained in 6 out of 7 patients reinvestigated 2 days to 6 months (average 6 months) after the initial procedure: the only case of reocclusion occurred after 48 hours on a RCA. The overall procedure never exceeded 2 hours.
