摘　　要：支架成形术在介入治疗中占有非常重要的地位。目前临床应用主要以永久性支架为主,具有炎性增生和再狭窄等并发症存在,难以在良性狭窄性病变及儿童病例中广泛应用。生物可降解支架从理论上克服了永久性支架的缺点,具有很大的临床应用前景。目前生物可降解支架技术已经日趋成熟,通过动物实验和初步临床应用,取得了较为满意的效果。相信在不久的将来,生物可降解支架在许多良性疾病中都将得到广泛应用,从而成为永久性支架以外很好的补充治疗手段。Stent implantation plays an significant role in the interventional therapy, mainly with permanent stent, possessing many disadvantages such as restenosis and inflammatory hyperplasia and can thus hardly be used in children and nonmalignant stenosis. Biodegradable stent has theoretical capability to solve these problems and acquires a bright future. Nowadays, with the development of material industry and manufacture craft, biodegradable stent technique has turned up to be mature in last decades. Through the strict animal experiments and prophase of clinic application, satisfactory result has been acquired. We believe that bioabsorbable stent will be widely used in many benign diseases which would be a good supplement for permanent stent in the near future.
