【摘要】：目的通過產(chǎn)前超聲診斷探討胎兒不同下腔靜脈變異的發(fā)病率及變異的下腔靜脈內徑和血流峰速與正常下腔靜脈相比是否有差異。方法回顧性分析37 448例行產(chǎn)前超聲檢查的胎兒資料,篩查出下腔靜脈變異的病例,計算其發(fā)病率;比較變異組與正常組胎兒的下腔靜脈內徑及S波血流峰速有無差異。結果在所有受檢胎兒中,左位下腔靜脈54例(1.44‰),雙下腔靜脈14例(0.37‰)。正常胎兒下腔靜脈內徑為(2.71±0.42)mm,血流峰速為(36.25±6.30)cm/s;左位下腔靜脈內徑為(2.70±0.45)mm,血流峰速為(36.55±7.53)cm/s,與正常組相比差異均無統(tǒng)計學意義(t=6.78,P0.05;t=3.56,P0.05);雙下腔靜脈內徑為(2.72±0.50)mm,血流峰速為(36.18±7.49)cm/s,與正常組相比差異均無統(tǒng)計學意義(t=10.43,P0.05;t=7.01,P0.05)。結論左位下腔靜脈發(fā)病率為1.44‰,雙下腔靜脈發(fā)病率為0.37‰,兩種變異的下腔靜脈內徑和血流峰速與正常組相比無明顯差異。
[Abstract]:Objective to investigate the incidence of fetal variation of inferior vena cava (IVC) and whether there are differences in the diameter of IVC and peak velocity of blood flow between fetus and normal IVC by prenatal ultrasound diagnosis. Methods 37 448 cases were analyzed retrospectively. Sonographic fetal data, The incidence of IVC variation was calculated, and the differences of IVC diameter and S wave blood flow peak velocity between the variant group and the normal group were compared. Results among all the tested fetuses, there were no significant differences in the diameter of IVC and the peak velocity of S-wave blood flow. Left inferior vena cava (IVC) was found in 54 cases (1.44 鈥，
