Prenatal sonographic features of congenital vascular ring / 中国基层医药

ABSTRACT

Objective To analyze prenatal sonographic features and clinical diagnostic evaluation of congenital vascular ring.Methods The clinical data of 52 children with congenital vascular ring were analyzed to explore the characteristics and prenatal sonographic diagnosis mainly in congenital vascular ring.Results 52 cases of fetuses with vagus right subclavian artery 7 cases,right aortic arch with the left artery catheter in 38 cases,2 cases of pulmo-nary artery sling,5 cases of double aortic arch,and there were different types of ultrasound performance.In 52 cases of fetus,16 patients with malformations,accounting for 30.77%.Among them,the top three were ventricular septal defect,tetralogy of fallot,fetal polycystic kidney agenesis,which accounted for 50.00%,12.50% and 12.50%. 52 cases confirmed by autopsy,12 cases chose to terminate the pregnancy,24 cases choice of delivery.Among them, 20 cases of right aortic arch with the left side of the ductus arteriosus,pulmonary artery sling choose one case of child-birth and vagus right subclavian artery three cases,post -natal ultrasonography right aortic arch in 16 cases,and the remaining 16 patients were lost.Conclusion Prenatal sonography in diagnosis of congenital vascular ring has desired effect,three -vessel trachea view through accurate diagnosis and identification of congenital vascular ring,and it should be widely applied.
