139例PTCA,成功率为86.3%。未成功者19例中7例PTCA导管未能通过或达到狭窄区;6例因狭窄病变弥散伴钙化,扩张后压力阶差和狭窄减少不明显;6例为严重的急性血管闭塞,其中一例死亡。作者详细讨论了上述并发症的预防和处理,强调术前认真阅读冠脉造影电影片,分析病变性质是否适于扩张这是PTCA获得成功和预防并发症的关键。 139 cases of PTCA, the success rate was 86.3%. Of the 19 unsuccessful cases, 7 cases of PTCA catheter failed to pass or reach the stenosis area; 6 cases of diffuse and calcified calcification due to stenosis lesion, pressure gradient and stenosis was not obvious after dilatation; 6 cases of severe acute vascular occlusion, of which one died . The authors discuss in detail the prevention and management of these complications and emphasize that careful reading of coronary angiograms before surgery and analysis of the appropriateness of the lesion for expansion are the keys to successful and preventable complications of PTCA.
