Restenosis after percutaneous transluminal coronary angioplasty was demonstrated in 61 (29%) of 210 successfully treated patients. Mostly it occurred within 4 months after treatment and in arteries less than 3 mm in diameter. Careful clinical follow-up is therefore particularly important early after angioplasty of smaller arteries. Redilation can be performed without increased risk of restenosis.
在210例成功接受经皮腔内冠状动脉成形术的患者中，有61例（29%）出现了再狭窄。再狭窄大多发生在治疗后的4个月内，且多见于直径小于3毫米的动脉。因此，在对较小动脉进行血管成形术后早期，仔细的临床随访尤为重要。再次扩张可在不增加再狭窄风险的情况下进行。
