传统的胸腺瘤(liu)手(shou)术要从正中劈开(kai)胸骨,出(chu)血多(duo),创伤(shang)大,术后留(liu)下一条长长的疤(ba)痕,病人痛不(bu)堪言。而常规经肋间(jian)胸腔镜无(wu)法进行对侧纵膈(ge)脂(zhi)肪(fang)的清扫。而与(yu)开胸手术相(xiang)比,经剑突下胸腔镜(jing)纵隔肿(zhong)瘤切(qie)除术是(shi)在(zai)胸(xiong)骨(gu)和心(xin)包之(zhi)间的间隙进行,通(tong)过形成(cheng)人工气(qi)胸,为(wei)手术操作提供(gong)了(le)宽阔清(qing)晰的(de)视(shi)野,避免了胸骨切开。
