Interventions
Fetoscopic laser ablation
Under ultrasound guidance, a 2 mm skin incision will be made and a 10Fr Cook Check Flow valve cannula and trocar will be introduced into the amniotic cavity. The communicating vessels will be located endoscopically using a Storz straight or curved semirigid fetoscopes in a fetoscopic sheath, a Humanitarian Use Device, used with permission of the Federal Drug Administration under a Humanitarian Device Exemption agreement with Karl Storz, Inc, and will be ablated with a diode laser fiber that is passed through the operating channel of the endoscope.
