In utero limb salvage: fetoscopic release of amniotic bands for threatened limb amputation

The natural history of extremity amniotic band syndrome (ABS) is a progression to deformity or amputation. Fetoscopic laser release of amniotic bands in extremity ABS offers the potential to prevent limb amputation. The authors report on 2 patients with isolated extremity ABS who underwent fetoscopic release. Both patients had isolated extremity ABS with compromised extremity perfusion and no other significant structural abnormality diagnosed sonographically. The first patient underwent fetoscopic release of bands of the left wrist, and the second patient underwent lysis of bands around the right wrist and an unsuspected band around the right lower extremity. Both patients had restoration of blood flow by color Doppler to the affected extremity. There were no perioperative complications. In select patients with isolated extremity ABS, early fetoscopic release may prevent amputation and allow improved limb development.
