经皮球囊主动脉缩窄扩张术9例疗效观察

Effect and follow up of balloon dilatation angioplasty for the treatment of coarctation of the aorta in children

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。

To evaluate the effect of balloon dilatation angioplasty for the treatment of coarctation of the aorta (mem-brane type) in children who never undertaken surgery, balloon dilatation angioplasty were performed in 9 children with coarctation of the aorta at a average age of(4. 92±3. 99)years. The diameter of balloon used was greater 3-4 times than that of the coarctation area, or was not greater than that of aorta located on the proximal end of coarctation area. The results showed that hypertension in all patients were soon controlled after successful surgery. The gradient pressure decreased significantly from 46. 80±15. 30 mmHg to 8. 4±8. 33 mmHg (P<0. 005). The blood pressure of lower extremities were over or similar to that of upper ones (mean pressure gradient was 11. 25mmHg-19. 5 mmHg). No aneurysm was formed in any case. It is concluded that balloon dilatation angioplasty was an effect, safe and simple method for the treatment of coarctation of the aorta (membrane type).
