A technique of fetal transfusion using sonographic guidance for needle placement is described. Sixteen patients underwent a total of 43 transfusions. The fetal mortality risk appears to be lower than that encountered in fluoroscopy-directed transfusions. Fetal irradiation has been dramatically reduced from an average of 2.2 rads per transfusion to 0.29 rads per transfusion. The technique allows very precise placement of a needle within the uterus or fetus. We have used it in difficult cases for amniocentesis. The technique could also be adapted to other problems requiring accurate placement of a needle within the body, such as biopsy of masses or aspiration of cysts.
本文描述了一种在超声引导下进行胎儿输血的技术，用于针头定位。16名患者共接受了43次输血。胎儿死亡风险似乎低于荧光镜引导下输血的风险。胎儿辐射量已从平均每次输血2.2拉德大幅降至每次输血0.29拉德。该技术可非常精确地将针头置于子宫或胎儿体内。我们已将其用于羊水穿刺的困难病例。该技术也可适用于其他需要在体内精确放置针头的问题，如肿块活检或囊肿抽吸。
