非体外循环下全腔静脉肺动脉连接术的临床应用

Clinical application of total cavopulmonary connection with off-pump technique

目的 评价非体外循环下全腔静脉肺动脉连接术的临床应用价值。方法 2 0 0 0年 5月至2 0 0 2年 12月 ,9例病人接受了非体外循环下的全腔静脉肺动脉连接术。其中男 5例 ,女 4例。年龄 4～2 4岁 ,平均 (10 3± 6 4 )岁。体表面积 0 6 5～ 1 6 6m2 ,平均 (0 95± 0 35 )m2 。术前经皮血氧饱和度 0 6 0～0 80 ,平均 0 73± 0 0 6。术中测肺动脉压 10～ 16mmHg(1mmHg =0 133kPa) ,平均 (12 7± 2 4 )mmHg。结果 1例死亡。 1例出现乳糜胸 ,2例术后早期循环不稳定又行外管道与右心房开窗术。所有生存病人出院时无明显发绀 ,呼吸空气时经皮血氧饱和度 0 89～ 0 97,平均 0 94± 0 0 3。结论 非体外循环下的全腔静脉肺动脉连接术操作较为简便 ,术后早期效果良好。

Objective: To evaluate the clinical application of total cavopulmonary connection with off-pump technique. Methods: Between May 2000 and December 2002, 9 patients underwent total cavopulmonary connection without cardiopulmonary bypass. The patients were 5 males and 4 females, mean age (10.3±6.4) years, ranged 4～24 years and mean body surface area (0.95±0.35) m 2, range 0.65～1.66 m 2. SpO 2 before operation was (73±6)% (60%～80%). Pulmonary pressure was (12.7±2.4) mmHg (10～16 mmHg) at operation. Results: Patient died after surgery. Chylothorax occurred in 1 patient. 2 patients were reoperated for fenestration between the extracardiac conduit and right atrial during the early postoperative period. All survivors were noncyanotic, the average SpO 2 on breathing air was (94±3)% (89%～97%). On d ischarged. Conclusion: Total cavopulmonary connection with off-pump technique is a useful procedure in management of patients with a functional univentricular heart. It is easy to perform. However, much remains to be studied about this unique physiologic status.
