Prenatal diagnosis of isolated interrupted inferior vena cava with azygos continuation to superior vena cava.

Giang do TC, Rajeesh G, Vaidyanathan B - Ann Pediatr Cardiol (2014)

Bottom Line: Absence of inferior vena cava is an uncommon congenital abnormality.Detailed ultrasound examination of the fetal anatomy failed to demonstrate other anomalies.The neonatal course of this fetus was uneventful.

ABSTRACT
Absence of inferior vena cava is an uncommon congenital abnormality. It is usually associated with other structural anomalies, typically left isomerism. We report a case of interrupted inferior vena cava with azygos continuation diagnosed as an isolated finding during routine prenatal ultrasound scan, confirmed by post-natal echocardiography. Detailed ultrasound examination of the fetal anatomy failed to demonstrate other anomalies. The neonatal course of this fetus was uneventful.

Figure 5: Post-natal echocardiography sub-xiphoid view showing a dilated SVC with the venous channel (azygos vein) running parallel to the descending aorta (arrow) and joining the SVC. SVC = superior vena cava; RA = right atrium; Az = azygos vein

Mentions: A female baby weighing 2.8 Kg was delivered by elective caesarian section at 38 weeks. Clinical evaluation of the cardio-vascular system was unremarkable. A detailed cardiac evaluation was performed at 6 weeks post-natal age. ECG was unremarkable and showed sinus rhythm with normal atrio-ventricular conduction. Echocardiography confirmed the prenatal diagnosis of isolated inferior vena cava with azygos continuation to superior vena cava [Figure 5]. No other cardiac/extracardiac abnormalities were detected. The patient was advised follow-up and periodic monitoring for the development of any rhythm anomalies in future.
