From October 1985 to February 1992 we performed 80 percutaneous transluminal angioplasty (PTA) in 76 patients with coarctation of the aorta (CoAo). Sixteen of them with ages ranging from 12 to 62 years (mean = 21.1). We describe the experience in these cases. Fifteen with native and one with post-surgical coarctation. The gradient decreased from 72 +/- 33 to 18 +/- 17 mmHg immediately after dilation, in the follow-up (1 to 69 months m = 25) was 23 +/- 20 mmHg. In one patient we performed simultaneously angioplasty of CoAo and mitral valvuloplasty with excellent results in both lesions. We redilated two cases for residual gradient successfully. We had one failure in a patient with long coarctation. He needed surgery. In the initial experience we had one severe complication (cerebral stroke). No deaths or aneurysms. In conclusion we believe that PTA is an adequate alternative in adolescents and adults with native or post-surgical coarctation of the aorta with minimum incidence of complications.
1985年10月至1992年2月，我们对76例主动脉缩窄（CoAo）患者进行了80次经皮腔内血管成形术（PTA）。其中16例年龄在12岁至62岁之间（平均 = 21.1岁）。我们描述了这些病例的经验。15例为原发性，1例为手术后主动脉缩窄。扩张后即刻，压力阶差从72±33 mmHg降至18±17 mmHg，随访（1至69个月，平均 = 25个月）时为23±20 mmHg。在1例患者中，我们同时进行了主动脉缩窄血管成形术和二尖瓣成形术，两个病变均取得了良好效果。我们对2例残留压力阶差患者成功进行了再次扩张。1例长段主动脉缩窄患者手术失败，需要接受外科手术。在最初的经验中，我们发生了1例严重并发症（脑卒）。无死亡或动脉瘤发生。总之，我们认为PTA是青少年和成人原发性或手术后主动脉缩窄的一种合适替代方法，并发症发生率最低。
