Аннотация
OBJECTIVE: Our goal was to demonstrate the efficacy of transabdominal embryoscopy in the first trimester of pregnancy.
STUDY DESIGN: A patient at risk for Smith-Lemli-Opitz syndrome, type II, was referred for prenatal diagnosis at 11 weeks 5 days of gestation.
RESULTS: A transvaginal ultrasonographic examination revealed the presence of a nuchal membrane and bilateral polydactyly. A transabdominal embryoscopy confirmed the diagnosis of polydactyly. The patient had an unremarkable postprocedure course before termination of pregnancy 5 days later. In a second pregnancy embryoscopy revealed a normal fetal hand despite a suggestion on transvaginal ultrasonography that there was polydactyly. On the basis of this information the patient elected to continue the pregnancy, and a normal baby was delivered at 35 weeks.
CONCLUSION: This case validates the efficacy of noninvasive and invasive techniques, used adjunctively, in the first-trimester diagnosis of a lethal fetal condition composed of subtle phenotypic manifestations.
