title: [Acute vascular occlusion caused by percutaneous transluminal coronary angioplasty: early and late results of repeat-PTCA].
abstract: Acute vascular occlusion after percutaneous transluminal coronary angioplasty (PTCA) often necessitates a prompt aortocoronary bypass-operation (CABG). Alternatively, a re-PTCA can be attempted. In 1500 consecutive patients there was acute symptomatic occlusion due to PTCA 5 min to 16 h after the operation in 47 cases (3.1%). An immediate re-PTCA was attempted in all cases.
  
  
  RESULTS
  Reopening was successful in 43 of 47 cases (91%): in 15 patients (30%) within 30 min, in 36 patients (68%) within 60 min and in 42 patients (89%) within 90 min. In eight patients there was early re-occlusion 30 min to 20 h after re-PTCA, necessitating acute CABG in four patients. In 35 patients with re-PTCA the vessel remained open. Re-stenosis occurred within 1 to 10 days in 10 patients, and in additional 12 patients after 2-4 months. In most cases an additional PTCA was successful.
  
  
  RESULTS
  Six patients had an emergency CABG (three with an exchange wire as a stent in the dissected coronary artery). Three patients died (one after CABG); 14 patients experienced myocardial infarction (30%) (in three of these 14 the infarct was large).
  
  
  CONCLUSIONS
  Acute vascular occlusion after PTCA can successfully be treated by re-PTCA in four of five cases. However a rate of re-stenosis of about 60% is to be anticipated. Reperfusion with re-PTCA is fast and in these patients with transmural ischemia there are obviously less complications in comparison to emergency CABG after PTCA. 60% of the patients remain symptom free or markedly improved and without infarction or emergency CABG after 4 months.
