目的 :介绍新生儿主动脉缩窄切除和传统的或扩大的端端吻合术经验。方法 :对 2 5例主动脉缩窄新生儿 ,行主动脉缩窄段切除和传统的或扩大的端端吻合术 ,手术均经左胸后外侧第 3肋间进胸。结果 :全组患儿无手术死亡 ,无神经系统并发症。随访 2～ 2 4个月 ,平均 8.2个月。术后多普勒超声测定跨修复点压力阶差 (1 .6± 0 .8) k Pa较术前 (6 .8± 2 .1 ) k Pa有显著性降低 (P<0 .0 5 )。结论 :主动脉缩窄段切除和端端吻合术是矫治新生儿主动脉缩窄的有效方法 ,扩大的端端吻合术适用于主动脉弓发育不良的患儿。
OBJECTIVE: To introduce neonatal aortic constriction resection and traditional or enlarged end-stage anastomosis experience. Methods: Twenty-five neonates with aortic stenosis underwent aortic stenosis resection and conventional or enlarged end-to-end anastomosis. The operations were all performed through the left intercostal third intercostal space. Results: All patients had no surgical death and no neurological complications. All cases were followed up for 2 ~ 24 months with an average of 8.2 months. The postoperative Doppler echocardiographic pressure gradient (1.66 ± 0.88) kPa was significantly lower than that of the preoperative (6.2 ± 2.1) kPa (P <0.05) . CONCLUSION: Aortic banding and anastomosis are effective methods for the treatment of neonate aortic constriction. An enlarged end-to-end anastomosis is suitable for children with aortic arch dysplasia.
