【摘要】 目的:探討超聲對快速二期大動脈調轉術治療完全性大動脈轉位(D—TGA)的臨床應用價值。方法:總結分析2005年8月—2011年6月15例施行快速二期大動脈調轉術的D—TGA患兒超聲心動圖表現,比較術前、術中、術后左心室的變化及手術結果,總結分析一期肺動脈環縮術后行二期手術的最佳時機。結果:15例患者一期術后,評估解剖左室,顯示室間隔凸向右室面,左心室呈圓形,提示實行二期手術時機已到。二期術后一個月內死亡4例,手術成功率約73.3%。術后3個月隨訪,1例死于重癥肺炎,其余10例主動脈、肺動脈吻合口血流通暢。結論:超聲心動圖對快速二期大動脈調轉術治療D—TGA的評估手術時機、術中監測以及術后隨訪均發揮著十分重要的作用。

Clinical Study of Echocardiography in Rapid Two—stage Arterial Switch Operation for Patients with Transposition of Great Arteries/CHU Wen.//Medical Innovation of China,2012,9(29):030—031
【Abstract】 Objective:To evaluate the value of echocardiography in rapid two—stage arterial switch operation for patients with transposition of great arteries(D—TGA).Method:15 patients of D—TGA underwent rapid two—stage arterial switch operation from August 2005 to June 2011.Trace above 15 cases during every phrases of surgery with echocardiography.Result:For 15 cases of rapid two—stage ASO,we could find a left to right bulging of the interventricular when the left ventricule had a circular shape and left ventricule diastolic dimension(LVDD) increased after pulmonary artery banding.Above reminded to two—stage AS0.4 patients died among 1 month after rapid two—stage arterial switch operation.3 months later after operation,1 patient died for lung inflammation.Conclusion:Echocardiography plays an important role in studying ASO during every phrases of surgery.

完全性大動脈轉位(D—transposition of the great arteries,D—TGA)是新生兒期最易發生心力衰竭、死亡率最高的紫紺型先心病。大動脈調轉術(arterial switch operation,ASO)治療D—TGA要求患兒在出生后3周內。若患兒診治時年齡稍大,左心室心肌退化,直接行ASO成功率較低[1],可行快速二期大動脈調轉術。本研究總結分析施行快速二期大動脈調轉術的患兒超聲心動圖表現,探討超聲對該手術的術中檢測及術后療效評估的應用價值。
