双向Glenn手术治疗儿童功能性单心室68例分析

目的总结1998年4月至2005年12月行双向Glenn手术治疗68例儿童功能性单心室的经验。方法本组男47例,女21例;年龄5个月～14岁（中位年龄3．7岁）;体重6．7～30．0kg（中位体重12．5kg）。右侧双向Glenn手术39例,左侧双向Glenn手术13例,双侧者16例。同期行肺动脉环束3例、肺动脉结扎1例、主动脉-肺动脉分流管道切断缝合术1例、动脉导管结扎6例、大侧支循环切断4例、全肺静脉异位引流矫治1例、部分肺静脉异位引流矫治2例、房室瓣整形4例。结果68例患者死亡3例,病死率4．4％。术后上腔静脉压力（15．9±2．4）mmHg（1mmHg=0．133kPa）,较术前的（8．3±1．8）mmHg显著上升（P〈0．01）。术后安静时经皮血氧饱和度（89．3±4．2）％,较术前的（78．4±6．0）％显著上升（P〈0．01）。结论双向Glenn手术治疗功能性单心室效果满意;双向Glenn手术宜保留肺动脉的搏动性血流。

The application of bidirectional Glenn procedure on 68 pediatric cases with functional univentricle heart

OBJECTIVE: To analyze 68 pediatric cases with functional univentricle heart who underwent bidirectional Glenn procedure during from April 1998 to December 2005. METHODS: There were 47 males and 21 females in this group, aged from 5 months to 14 years old and weighed from 6.7 to 30.0 kg. Among them, 39 cases were received bidirectional Glenn procedure on the right side, 13 cases on the left side and 16 cases on both sides. Three cases had the pulmonary artery banded; one case had the pulmonary artery ligated;one case had the original A-P shunt cut off; six cases had the PDA ligated; four cases had the MAPCAs cut off; one case had TAPVC corrected contemporarily; two cases of PAPVC were also corrected; four cases had the atrial-ventricular valve repaired. RESULTS: Three cases died. The mortality was 4.4%. The mean post-operative pressure of super vena cava was (15.9 +/- 2.4) mm Hg (1 mm Hg = 0.133 kPa), higher than the pre-operative one (8.3 +/- 1.8) mm Hg (P < 0.01). The mean post operative SpO(2) was (89.3 +/- 4.2)%, higher than the pre-operative one (78.4 +/- 6.0)% (P < 0.01). CONCLUSIONS: Bidirectional Glenn procedure is of satisfied effect on surgical treatment for functional univentricle heart. The persistent forward flow from pulmonary artery should be reserved in bidirectional Glenn procedure.
