Abstract:
Objective To explore the clinical value of prenatal ultrasound and magnetic resonance imaging in the vein of Galen aneurysmal malformation. Methods The ultrasonographic characteristics and magnetic resonance imaging features of 17 fetuses who were diagnosed as the vein of Galen aneurysmal malformation in Maternal and Child Heath Hospital of Hubei from January 2011 to December 2016 were compared. Results Fifteen cases of Galen aneurysmal malformation. Were diagnosed by prenatal ultrasound during the third trimester. The sonographic feature was a hypoechogenic structure located in the middle line with arteriovenous fistula waveform in doppler analysis, and the cerebral venous sinus of all cases were dilated. Real time three dimensional power doppler can display the angioarchitecture and the communications between widened vascular sinus. MRI feature was the expansion of venous aneurysm located in the middle line, greater cerebral venous pool and quadrigeminal area and tortuous flow void vessels. Among 17 cases, 2 cases of Galen venous aneurysm malformation were misdiagnosed and 7 cases were diagnosed by MRI. There were 15 terminations and 2 neonatal died after birth. Conclusions Galen aneurysmal malformations have typical sonographic findings, and MRI can show neurologic development and impairment. Combined application of ultrasound and magnetic resonance imaging technology can more accurately and comprehensively observe the pathological features of Galen venous aneurysm malformation and diagnose the related complications early.
