目的 探讨左心房粘液瘤的诊断和治疗经验 ,以提高手术疗效。 方法 回顾性分析自 1995年 10月至2 0 0 1年 10月收治 5 7例左心房粘液瘤病例 ,术前均经彩色超声心动图确诊 ,均在体外循环下行粘液瘤摘除术 ,同期行二尖瓣成形术 5例 ,二尖瓣机械瓣置换术 2例 ,三尖瓣成形术 37例 ,房间隔缺损修补术 2例 ,隔膜型主动脉瓣下狭窄环切开术 1例。 结果 无围术期及手术死亡 ,随访 1个月～ 6年 ,2例复发再次手术 ,复发率 3.5 %。 结论 左心房粘液瘤一经确诊应尽快手术 ,手术效果满意 ,复发率低 ;彩色超声心动图对诊断及术后随访有重要作用 ,应注意术后随访。
Objective To investigate the diagnosis and treatment of left atrial myxoma in order to improve the curative effect. Methods Retrospective analysis of 57 cases of left atrial myxoma treated from October 1995 to October 2001 were confirmed by color echocardiography before operation. All patients underwent myxoma removal under cardiopulmonary bypass. 5 cases of mitral valve plasty, 2 cases of mitral valve replacement, 37 cases of tricuspid valvuloplasty, 2 cases of atrial septal defect repair, and 1 case of diaphragm-type aortic valve stenosis. Results There were no perioperative and operative deaths. The patients were followed up for 1 month to 6 years. Two patients were recruited for recurrence and reoperation. The recurrence rate was 3.5%. Conclusion Left atrial myxoma should be operated as soon as it is diagnosed. The operation result is satisfactory and the recurrence rate is low. Color echocardiography plays an important role in the diagnosis and postoperative follow-up, and should be followed up.
