摘要: 目的 总结动脉导管未闭合并其他心脏畸形的外科治疗经验, 以提高手术效果。 方法 2004 年11 月~2006 年12 月手术治疗动脉导管未闭合并其他心脏畸形44 例, 40 例采用正中切口, 上、下腔静脉插管, 转流前游离动脉导管, 双10 号线结扎; 对导管粗大者可在并行转流下分离导管并结扎, 4 例患者实行分期手术。 结果 本组无手术死亡。术后发生低心排血量综合征3 例, 经积极治疗治愈; 2 例发生血红蛋白尿, 均在2d 内恢复。44 例术后超声心动图复查均无再通, 无灌注肺发生。术后随访36 例, 均在3 个月~ 2 年顺利恢复, 活动正常。 结论 经胸部正中切口手术是一种简单、有效的方法, 可同时修补其他心内畸形。分离、结扎动脉导管时应熟练掌握导管及其邻近解剖关系, 根据生命体征及导管直径的大小决定是否应用并行心肺转流。

Abstracts: Objective To summarize clinical experience and surgical outcomes of congenital coronary arterial fistula (CAF). Methods We retrospectively analyzed clinical records of 12 patients (6 males, 6 females), aged from 4 to 77 (50.90±23.8) years, who underwent surgical repair of CAF in Nanjing First Hospital between February 2005 and June 2011. There were 3 CAF patients associated with coronary artery aneurysms, one with patent foramen ovale and 2 with coronary artery disease (CAD). One CAD patient had concomitant severe aortic valve stenosis. One patient underwent surgical repair without cardiopulmonary bypass (CPB) and 11 patients underwent surgery under CPB, among whom 3 patients underwent surgery with beating heart. One patient underwent concomitant aortic valve replacement and coronary artery bypass grafting.?Results?All the patients recovered uneventfully. Operation time was 151.25±42.65 min (ranging from 90 to 245 min), cardiopulmonary bypass time was 65.06±29.16 min (ranging from 31 to 116 min), mean aortic cross-clamping time was 43.00±33.41 min (ranging from 18 to 97 min) and postoperative hospital stay was 12.50±1.45 d (ranging from 10 to 15 d). There was no early or late death. All the patients were followed up from 4 months to 6 years and no patient had symptom recurrence, myocardial ischemia or residual fistula during the follow-up. Conclusions All CAF patients should be surgically treated once diagnosis are made with satisfactory surgical outcome.

目的 探讨三尖瓣关闭不全(TI)外科治疗时机、手术方式与疗效的关系。 方法 回顾性分析中山大学附属第一医院2003年1月至2010年10月手术治疗的282例TI患者的临床资料,其中男115例,女167例;年龄(42.00±15.90) 岁。按手术方式分为三尖瓣置换术(TVR)34例,三尖瓣成形术(TVP)248例(包括改良De Vega成形术、Kay’s成形术、瓣裂修补术、人工瓣环成形术),评价患者疗效。 结果 术后早期死亡13例,死于低心排血量综合征7例,室性心律失常3例,感染性休克2例,心脏破裂1例。早期死亡率为4.61% (13/282)。手术时间(167.47±37.34) min,体外循环时间(109.67±27.98) min,主动脉阻断时间(66.20±18.42) min,住院时间(16.46±5.29) d。术后1年随访249例,三尖瓣反流改善总有效率为90.76% (226/249)),其中改良De Vega成形术有效率为91.41% (117/128),Kay’s成形术为80.49% (33/41),瓣裂修补术为92.31% (24/26),人工瓣环成形术为96.00% (24/25),TVP为96.55%(28/29)。术后肺动脉压较术前明显降低(P<0.01),右心室内径缩小。 结论 对中-重度TI或瓣环明显扩大者,应积极手术干预;Kay’s成形术后三尖瓣反流复发率较高,人工瓣环成形术效果良好;对于瓣膜发育不良或毁损者应首选TVR。
