浅低温体外循环心脏不停跳下心房黏液瘤手术分析

目的探讨浅低温体外循环（CPB）心脏不停跳下心房黏液瘤的手术方法及效果。方法回顾性分析2003年1月-2009年3月原发性心房黏液瘤患者的临床资料及手术方法，所有患者均在全麻浅低温CPB心脏跳动中手术。结果CPB时间19～69（42．2±14．9）min，施行左房黏液瘤摘除37例、右房黏液瘤摘除5例、双房黏液瘤摘除2例，无脑栓、气栓等并发症及围术期死亡，均痊愈出院。随访1个月～6a，38例得到有效随访，6例失访，均未见复发。结论心房黏液瘤诊断明确后应尽早手术，采用浅低温CPB心脏跳动中手术是切实可行的方法。

Clinical analysis of atrial myxoma surgery under superficial hypothermia and extracorporeal circulation without heart beating cease

Objective To investigate the effects of surgical treatment of atrial myxoma under superficial hypothermia and eardiopulmonary bypass （CPB） without heart beating cease. Methods Clinical data of 44 patients with primary atrial myxoma from January 2003 to March 2009 were retrospectively analysised. All of atrial myxoma was excised under general anesthesia with superficial low temperature extraeorporal circulation on beating heart. Results CPB time was 19-69 （42.2 ±14.9） rain. All of 37 cases of left atria/myxoma and 5 cases of right atrial myxoma and 2 eases of double atrial myxoma were reseeted sueeessfully without cerebral or gas embolism, postoperative complications and death in period of operation. Patients were followed up for 1 month to 6 years with the follow-up rate of 86.4%. All cases didn＇ t relapsed after opera- tion. Conclusions Atrial myxoma should be early performed operation after diagnosis, and intraeardiae procedures on pump beating-heart with superficial hypothermia CPB is safe and available in patients with atrial myxoma
