Percutaneous transluminal balloon angioplasty has been documented as a useful procedure in the treatment of recurrent coarctation of the aorta. In this project we present our experience and results.
Percutaneous transluminal balloon angioplasty was performed in 7 children with postsurgical coarctation of the aorta. Six of them had previous coarctation of the aorta and one had a iatrogenic result of a persistent ductus arteriosus operation.
Mean pressure difference across the coarctation decreased from mean = 51 +/- 16 mmHg to mean = 14 +/- 6 mmHg after the angioplasty and mean diameter of the aortic lumen at the coarctation site increased from mean = 3.6 +/- 1.4 to mean = 8.7 +/- 1.2 mm. All patients are asymptomatic and normotensive at least during the following two years after the procedure. Only the patient who had iatrogenic coarctation still has a residual gradient of 30 mmHg. There were not any major complications during the procedure or after it.
Percutaneous transluminal balloon angioplasty is a safe and effective procedure in the treatment of postsurgical coarctation of the aorta.
经皮腔内球囊血管成形术已被证明是治疗复发性主动脉缩窄的一种有效方法。在本项目中，我们展示了我们的经验和结果。
对7例主动脉缩窄术后患儿进行了经皮腔内球囊血管成形术。其中6例曾有主动脉缩窄，1例为动脉导管未闭手术的医源性结果。
血管成形术后，缩窄部位的平均压差从平均51±16 mmHg降至平均14±6 mmHg，缩窄部位主动脉腔的平均直径从平均3.6±1.4 mm增加到平均8.7±1.2 mm。所有患者在术后至少两年内均无症状且血压正常。只有医源性缩窄的患者仍有30 mmHg的残余压差。术中及术后均未出现任何严重并发症。
经皮腔内球囊血管成形术是治疗主动脉缩窄术后的一种安全有效的方法。
