A successful dilatation of a supravalvular pulmonary stenosis after banding operation is described in a 19-year-old male. The dilatation was performed during transesophageal echocardiographic monitoring. Dilatation with a 15-mm and a 19-mm valvuloplasty catheter was not successful. Using the "kissing-balloon" technique with a 15 and 19 mm balloon together, the pressure gradient could be reduced from 59 mm Hg to 10 mm Hg (mean 41 and 8 mm Hg). Pulmonary artery diameter increased from 17 to 24 mm without intima damage or dissection. Thus pulmonary artery stenosis caused by banding operation can be dilated successfully. Monitoring during the procedure quickly demonstrates the changes in the dilated vessel. Angiography 6 months later showed slight restenosis of the dilated vessel with a maximum pressure gradient of 27 mm Hg (mean 17).
本文描述了一名19岁男性在束带手术后成功扩张肺动脉瓣上狭窄的病例。扩张过程在经食管超声心动图监测下进行。使用15毫米和19毫米的瓣膜成形导管进行扩张未成功。采用“双球囊”技术，同时使用15毫米和19毫米的球囊，可使压力阶差从59毫米汞柱降至10毫米汞柱（平均分别为41毫米汞柱和8毫米汞柱）。肺动脉直径从17毫米增加到24毫米，未出现内膜损伤或夹层。因此，束带手术所致的肺动脉狭窄可成功扩张。术中监测可快速显示扩张血管的变化。6个月后的血管造影显示扩张血管有轻微再狭窄，最大压力阶差为27毫米汞柱（平均17毫米汞柱）。
