METHODS: Prospective study of eight cases diagnosed with TTTS evaluated in our service from january 2001 to june 2005. Through percutaneous introduction of a 2,0mm diameter fetoscope in the uterine cavity, placental surface vessels where directly visualized. Those identified as responsible for the transfusion were laser coagulated. The procedure combines ultrasonography and fetoscopy, in a so-called sonoendoscopic technique (FETENDO). RESULTS: Among the eight pregnancies evaluated, five cases were submitted to the procedure (10 fetuses). All fetuses survived for at least five weeks after surgery. A total of eight fetuses were born alive and five survived the neonatal period. In a 18 months follow-up after birth, all five are still alive and well and their mean age is now 10,6 months. The total survival rate was 50% and in three pregnancies, at least one fetus survived. CONCLUSIONS: Laser fetoscopy is actually the \"gold-standard\" treatment of TTTS. Nevertheless is a sophisticated technique that epends of proper training. Our service is the first in our country to offer this therapeutic technique. Our success rate is comparable with the international literature.<\/jats:p>","DOI":"10.1590\/s0102-86502005000600015","type":"journal-article","created":{"date-parts":[[2006,1,9]],"date-time":"2006-01-09T12:26:48Z","timestamp":1136809608000},"page":"478-481","source":"Crossref","is-referenced-by-count":7,"title":["Laser
