Abstract:
Objective To investigate the value of clinical follow-up in prenatal diagnosis of isolated double aortic arch (DAA) . Methods The clinical follow-up materials were retrospectively reviewed in 17 fetuses . Of all the isolated DAA fetuses ,the accuracy rate of prenatal diagnosis was confirmed by CT ,MRI , autopsy or echocardiography ,and pregnant outcomes were summarized . Results A total of 17 fetuses had a sonographic diagnosis of isolated DAA in our centers at a mean gestational age of 23 -32(27 ± 3) weeks , with mother mean age 19 -44 (28 ± 6) years old . One case of DAA type-A was misdiagnosed ,15 cases were delivered with 2 cases occurred respiratory distress or mild dysphagia ,who received surgical treatment , and 13 cases clinical findings were unremarkable at the fellow-up of 24 months ,the silent-rate of clinical symptoms was 86％ . Termination of pregnancy happened in 2 cases ,with 1 (6％ ) had additional ventricular septal defects ,another ( 6％ ) had additional anomalies of congenital high airway obstruction syndrome . In 17 cases of fetuses with isolated DAA ,there were 15 ( 88％ ) cases with dominant right-sided arch ,1 case (6％ ) with dominant left arch ,and 1 case (6％ ) with equal arches in size .Karyotyping prenatal testing was offered to 15 parents with normal results . Conclusions Prenatal ultrasound can accurately diagnose isolated DAA by multiple sections scan ,expanding diagnostic ideas by combination with other medical imaging data to prevent apparent life-threatening event ,or to guide for ex-utero intrapartum treatment . Isolated DAA clinical follow-up results in good outcome .
