左心房黏液瘤的急救治療
【摘要】 目的 探討左心房黏液瘤的診斷和治療經(jīng)驗(yàn),以提高手術(shù)療效。方法 回顧分析2002年1月至2007年6月我院收治的15例左心房黏液瘤病例,術(shù)前均經(jīng)彩色超聲心動(dòng)圖確診,均在體外循環(huán)下行黏液瘤摘除術(shù),同期行二尖瓣成形術(shù)1例,三尖瓣成形術(shù)5例,房間隔缺損修補(bǔ)術(shù)2例。結(jié)果 1例于術(shù)前死亡,余無(wú)圍術(shù)期及手術(shù)死亡,隨訪1個(gè)月~5年,1例復(fù)發(fā)再次手術(shù)。其余均達(dá)到臨床治愈。結(jié)論 左心房黏液瘤一經(jīng)確診應(yīng)盡快手術(shù),手術(shù)效果滿(mǎn)意,復(fù)發(fā)率低;彩色超聲心動(dòng)圖對(duì)診斷及術(shù)后隨訪有重要作用,應(yīng)注意術(shù)后隨訪。

[Abstract] Objective To study the experiences of diagnose and therapy on left atrial myxoma,for improving surgical results.Methods To investigate the clinical results,from January 2002 to June 2007,15 cases diagnosed left atrial myxoma by Doppler echocardiography were operated under cardiopulmonary bypass.Mitral valve proplasty were operated on one patien and tricuspid valve proplasty were operated on five patients,atrial septal defect were repaired on two patients.Results One case died before operation,the others got a successful results,no death happened on preoperative period and operative course.Follow-up for one month to five years was done,one case was admitted to reoperation for recurrence of left atrial myxoma.The other cases got a better clinical results.Conclusion early diagnosis and timely operation are very important to the patients of left atrial myxoma.Doppler Echocardiography would have an important usefulness to diagnose and postoperative follow-up.
[Key words] left heart atrium;myxoma;surgery operation
心臟黏液瘤是最常見(jiàn)的原發(fā)性心臟腫瘤,約占心臟腫瘤的25%,心臟良性腫瘤的50%[1]。左心房黏液瘤占心臟黏液瘤75%,雖多為良性病變,但可引起嚴(yán)重的血流動(dòng)力學(xué)改變,體、肺循環(huán)栓塞甚至猝死,危及患者的生命。因此,應(yīng)及早發(fā)現(xiàn)、及時(shí)手術(shù)治療。我科自2002年1月至2007年6月共收治15例左心房黏液瘤患者,均在體外循環(huán)下行手術(shù)摘除,術(shù)中經(jīng)過(guò)順利、術(shù)后恢復(fù)良好,現(xiàn)總結(jié)報(bào)告如下。
1 資料與方法
1.1 一般資料 本組15例,男10例,女5例,年齡18~59歲,平均(30.5±12.6)歲,病史36 h~2年。全組均有活動(dòng)后心悸、氣促、頭暈。1例有暈厥史,1例有腦栓塞偏癱,2例入院時(shí)不能平臥、咳粉紅色泡沫痰。心尖部聞及舒張期隆隆樣雜音8例,收縮期雜音3例,雙期雜音4例,癥狀和雜音隨體位改變而變化10例。胸部X線照片:心胸比率0.50~0.68,肺淤血11例,呈“二尖瓣型”心影9例。超聲心動(dòng)圖示左心房?jī)?nèi)有異常回聲光團(tuán),邊界清楚,可隨心臟舒縮而上下活動(dòng);有2例舒張期可見(jiàn)光團(tuán)進(jìn)入左心室。
1.2 手術(shù)方法 全組均在全麻、低溫、體外循環(huán)下行手術(shù)。采用胸骨正中劈開(kāi),右心房——房間隔切口,體外循環(huán)時(shí)間20~51 min,平均(27.6±11.9)min。術(shù)中見(jiàn)腫瘤位于左心房?jī)?nèi),有1例瘤體已嵌入二尖瓣口;有完整包膜12例,無(wú)完整包膜3例。瘤體呈葡萄狀類(lèi)圓形或橢圓形,顏色多樣,質(zhì)脆,膠凍樣。瘤體大小1.5 cm×1.5 cm×2.0 cm至(未完,下一頁(yè))
