경피적 관동맥 성형술의 임상적 경험 - 최초 성공율을 중심으로 - = Primary Success Rate of Percutaneous Transluminal Coronary Angioplasty

다국어 초록 (Multilingual Abstract)

Background: Percutaneous transluminal coronary angioplasty (PTCA) has been applied to some patients with symptomatic coronary artery disease and become recently an alternative to coronary artery bypass graft in selected cases. So we reviewed the results of our cases of PTCA. Method: PTCA was performed for 103 coronary arterial lesions in 78 patients (66 male, 12 female: 56.4±9.1 years) at Chonnam University Hospital from Aug. 1987 to April 1991. The acute results were assessed. Subjects: Eleven patients had stable angina, 32 unstable angina, 31 acute myocardial infarction, and four old myocardial infarction. Fortyfour patients had single vessel disease, 21 two vessel disease, and 13 three vessel disease. Results: Primary angiographic success rate was 74.8% (77/103) in the total 103 attempted lesions: 82.6% (38/46) in type A, 71.7% (38/53) in type B, and 25.0% (1/4) in type C according to ACC/AHA classification of the attempted coronary arterial lesions. The angiographic diameter stenosis reduced from 70.7±17.2% to 19.2±13.8% after successful PTCA. Complications associated with PTCA were seven intimal dissections (1 occlusive, 6 non-occlusive), one coronary occlusion by thrombosis, one coronary artery rupture, one guide wire impaction and fracture, and two deaths. There was no case requiring emergency CABG. Conclusion: Percutaneous transluminal coronary angioplasty (PTCA) can be an effective treatment in variable coronary artery disease and become an alternative to coronary artery bypass graft.
