Abstract：
Twin-to-twin transfusion syndrome (TTTS) could be treated with fetoscopic laser photocoagulation. For patients with placenta located on the anterior wall of uterus, surgical procedures are difficult. To solve this problem, a flexible fetoscope was designed in our department.
The flexible fetoscope was made up of polyurethane, fiberglass and stainless steel coils. The specular body was soft and could bend encountering obstacles, which reduced the possibility of injury to the fetus and placenta. The distal tip of the body could curve from -180° to +270° with the control of the handweel. Three pregnant women of TTTS with anterior placenta was operated with this instrument.
All pregnant women were treated smoothly and gave live twins birth at term. Through angiography, it was demonstrated that the vascular connections on the surface had been coagulated.
The flexible fetoscope was a novel instrument in treating TTTS, especially for the anterior placenta.
