Therapeutic techniques for in utero release of amniotic bands have relied on transecting instruments. We present an additional technique, blunt dissection, to release a constriction band in utero. The lower extremity that had detectable abnormalities during prenatal ultrasound had improved outcome after blunt in utero release of the amniotic band compared to the contralateral (control) leg. These findings support two conjectures: first, the degree of band adherence to the fetus is an important factor influencing the surgical approach to in utero lysis of the bands; second, that in utero release of constriction bands can result in improvement in outcome.
子宫内羊膜带松解的治疗技术一直依赖于切割器械。我们提出了一种额外的技术——钝性分离，用于在子宫内松解束带。与对侧（对照）腿相比，产前超声检查可检测到异常的下肢在子宫内钝性松解羊膜带后预后有所改善。这些发现支持了两种推测：第一，束带与胎儿的粘连程度是影响子宫内束带松解手术方式的重要因素；第二，子宫内松解束带可改善预后。
