title: Frequency, management and follow-up of patients with acute coronary occlusions after percutaneous transluminal coronary angioplasty.
abstract: Angiograms from 1,500 consecutive patients undergoing percutaneous transluminal coronary angioplasty (PTCA) at the Cleveland Clinic were reviewed to determine the frequency of acute coronary occlusion after successful PTCA. Thirty-two patients (2%) had acute coronary occlusions. Of these, 27 (84%) presented within 6 hours. Compared with control group, only the presence of eccentric lesions (72% vs 24%) and intimal tears (78% vs 34%) was more predominant in the group with acute occlusion. Redilation was attempted in 31 patients and was successful in 27 (87%). Nine of these patients eventually required coronary bypass surgery and 18 were discharged and followed for 11 to 34 months (mean 18). Thus, redilation is a safe and effective approach to manage patients in whom coronary occlusion develops after PTCA.
