Abstract
OBJECTIVE: We describe a new technique to achieve permanent umbilical cord occlusion. METHODS: A 3 mm in diameter bipolar diathermy forceps was built to house a 1.2 mm fetoscope, emerging between the blades of the forceps. The device can be inserted percutaneously through a 10 Fr Trocar into the amniotic cavity under local analgesia and ultrasound guidance. A monochorionic (MC) twin pregnancy with a twin reversed arterial perfusion sequence at 18 weeks of gestation underwent cord occlusion of the acardiac twin using this new device in 2004. RESULTS: The instrument allowed cord coagulation under direct visual control. The pregnancy continued until 33 weeks of gestation when a male infant of 1980 g was delivered by cesarean section following preterm labor. CONCLUSION: This new instrument might allow easier access to the cord and reduce operation time by direct visualization of the target and, therefore, improve the outcome after the procedure.
