【摘要】：目的探討二維超聲診斷胎兒主動脈縮窄(COA)的直接和間接指標(biāo)的應(yīng)用價值。方法回顧性分析經(jīng)胎兒超聲心動圖檢查診斷、并經(jīng)出生后或尸體檢查證實為COA的中孕期胎兒18胎。以主動脈峽部Z分?jǐn)?shù)(Z-AoI)-2、主動脈峽部內(nèi)徑(AoId)≤2.0 mm、主肺動脈內(nèi)徑/升主動脈內(nèi)徑(MPAd/AAOd)≥1.6、二尖瓣環(huán)橫徑/三尖瓣環(huán)橫徑(MVd/TVd)0.6為診斷標(biāo)準(zhǔn),分別分析其診斷符合率,同時測量主動脈瓣環(huán)內(nèi)徑(AOd),計算中孕期COA胎兒AOd的參考范圍。結(jié)果在18胎COA胎兒中,Z-AoI、AoId、MPAd/AAOd、MVd/TVd的診斷符合率分別為94.44%(17/18)、61.11%(11/18)、66.67%(12/18)、44.44%(8/18),差異有統(tǒng)計學(xué)意義(P0.05)。COA胎兒AOd的參考范圍為2.60~2.98mm。結(jié)論 Z-AoI診斷COA的符合率最高;中孕期COA胎兒AOd為2.60~2.98mm。
[Abstract]:Objective to evaluate the value of two-dimensional ultrasound in the diagnosis of direct and indirect indexes of fetal aortic coarctation (COA). Methods 18 fetuses diagnosed by fetal echocardiography and confirmed as COA by postnatal or cadaveric examination were analyzed retrospectively. The diagnostic criteria were Z fraction of aortic isthmus (Z-AoI)-2, aortic isthmus diameter (AoId) 鈮，
