Spina bifida echocardiography and ultrasound

Introduction

Overview

Overview

Compared with the general population, the prevalence of congenital heart disease in newborns with myelomeningocele is increased , however critical disease is uncommon. When the myelomeningocele is prenatally diagnosed, antenatal cardiac screening is complete and normal, and the newborn is clinically well, preoperative echocardiography is unnecessary. Ultrasound is the imaging modality of choice for characterisation of the open spina bifida spinal lesions. On two and tree-dimensional ultrasound, spina bifida is characterized by: Vertebral defect, splayed vertebral pedicles and disrupted vertebrae. The ultrasound must be performed when a positive alpha-fetoprotein is detected in the triple screening test between the 15th and 20th week of pregnancy to confirm the diagnosis.
