对未经外科手术的隔膜型主动脉缩窄9例患儿进行了经皮球囊扩张术,其平均年龄(4.92±3.99)岁,均经临床、心电图、X线及超声心动图检查确诊,采用比缩窄部直径大于3倍～4倍或不超过缩窄近端的主动脉直径的球囊予以扩张治疗。结果:手术全部成功,高血压即刻得到控制,跨缩窄部压差由(46.80±15.30)mmHg降至(8.40±8.33)mmHg。随访下肢血压超过或接近上肢,跨缩窄压差11.25mmHg～19.50mmHg,无动脉瘤形成。我们认为经皮球囊治疗未经外科手术的隔膜型主动脉缩窄是一种疗效好、安全、操作简单的方法。
Percutaneous balloon dilatation was performed in 9 children without diaphragm aortic stenosis. The mean age (4.92 ± 3.99) years old were all confirmed by clinical examination, electrocardiogram, X-ray and echocardiography. The balloon is dilated with a balloon larger than 3 to 4 times the diameter of the constriction or up to the constricted aortic diameter. Results: All operations were successful. Hypertension was immediately controlled and the pressure across the constriction decreased from (46.80 ± 15.30) mmHg to (8.40 ± 8.33) mmHg. Follow-up lower limb blood pressure over or close to the upper limb, across the narrowing pressure 11.25mmHg ~ 19.50mmHg, no aneurysm formation. We believe that percutaneous balloon treatment of non-surgical septal aortic constriction is a good effect, safe and easy to operate.
