We tested the feasibility of treating placental vascular anomalies with a fetoscopically delivered neodymium-yttrium-aluminum-garnet laser in pregnant ewes. This laser provided sufficient power in an amniotic fluid medium to occlude placental vessels as large as 7 mm in diameter within 6 seconds at a power density of 2000 W/cm2.
我们在怀孕母羊身上测试了用经胎儿镜递送的钕钇铝石榴石激光治疗胎盘血管异常的可行性。这种激光在羊水介质中提供了足够的能量,在功率密度为2000 W/cm2时,能在6秒内封闭直径达7毫米的胎盘血管。
