Percutaneous transluminal angioplasty (PTA) was used successfully to treat coarctation restenosis in seven patients. The patients were 10 months to 17 years old at the time of the angioplasty, and the initial coarctation repair had been performed 10 months to 16 1/2 years previously. PTA reduced the systolic pressure gradient across the coarctation from a mean of 58 mm Hg before the procedure to a mean of 13 mm Hg immediately after PTA. Follow-up has been from 1 to 14 months and indicates that the decrease in the systolic pressure gradient is persistent.
经皮腔内血管成形术（PTA）成功用于治疗7例缩窄性再狭窄患者。血管成形术时患者年龄为10个月至17岁，最初的缩窄修复手术在10个月至16.5年前进行。PTA使缩窄部位的收缩压梯度从术前平均58 mmHg降至PTA术后即刻平均13 mmHg。随访时间为1至14个月，结果表明收缩压梯度的降低持续存在。
