目的、方法 :采用 UM4型超声心动图仪床边监测引导球囊房间隔造口术(BAS)姑息治疗新生儿重症先天性心脏病 10例 ,其中完全性大动脉转位 5例 ,完全性肺静脉畸形引流 3例 ,解剖纠正型大动脉转位和左心发育不良并肺静脉引流异常各 1例。结果 :10例中 8例造口成功 ,效果满意。超声测量房间隔缺损口径 4.5～10 mm,平均 7.5 mm;多普勒测穿隔血流速度由 1.87± 0 .2 m/ sel降至 0 .71± 0 .2 m/eel;压力阶差由 12 .70± 3.0降至 2 .0 6± 1.46 mm Hg(P <0 .0 1)。 5例完全性大动脉转位血氧饱和度由 5 3.6± 15 .96 %升至 78.0± 12 .5 5 % (P <0 .0 1)。2例不成功因合并卵圆孔早闭及心室反位罕见畸形引起。结论 :BAS在超声引导下更加简便易行 ,安全可靠 ,对改善依赖卵圆孔开放维持生命的先心病患儿临床症状、延长生命有重要帮助
PURPOSE AND METHOD: A UM4 echocardiograph was used to monitor and guide bedside septostomy (BAS) in palliative treatment of 10 cases of severe neonatal congenital heart disease. Among them, complete transposition of the great arteries in 5 cases, complete pulmonary venous malformation Drainage in 3 cases, anatomical aortic transposition and left ventricular dysplasia and pulmonary anomalies in 1 case. Results: In 10 cases, 8 cases were successful in stoma. The results were satisfactory. Ultrasound measurement of atrial septal defect diameter 4.5 ~ 10 mm, an average of 7.5 mm; Doppler measured through the blood flow velocity decreased from 1.87 ± 0.2 m / sel to 0.71 ± 0. 2 m / eel; pressure gradient from 12 .70 ± 3.0 to 2.06 ± 1.46 mm Hg (P <0.01). Five cases of complete aortic transmigration oxygen saturation increased from 53.6 ± 15.96% to 78.0 ± 12.55% (P <0.01). 2 cases were unsuccessful due to merger foramen ovale early closure and ventricular anti-rare cause of abnormal. CONCLUSIONS: BAS is more simple and reliable under ultrasound guidance and safe and reliable. It is of great help to improve the clinical symptoms and prolong life of children with congenital heart disease who depend on open foramen ovale to maintain their life.
