Value of ultrasonography in diagnosing peripheral intraneural vascular anomalies / 中华超声影像学杂志

ABSTRACT

To evaluate the value of ultrasonography in diagnosing peripheral intraneural vascular anomalies . Methods The ultrasonographic images of 10 patients with peripheral intraneural vascular anomalies confirmed by surgery or pathology were retrospectively analyzed . T he ultrasonographic features were summarized . Results T he ultrasonographic images could not only clearly show the location , involvement and blood supply of peripheral intraneural vascular anomalies , but also determined the classification of them . Ultrasonography showed enlarging nerves ,within w hich tubular structures could be observed ,and the boundary between the vascular malformations and the perineurium was not clear . Abundant arteriovenous blood flow ( arteriovenous malformation) or low velocity venous blood flow ( venous malformation) within the vascular anomalies could be detected by color Doppler examination . Conclusions Ultrasonography is the preferred imaging method for diagnosis of peripheral intraneural vascular anomalies .
