Abstract:
A total of 62 cases with autogenous arteriovenous fistulas were examined bv color Doppler ultrasonography.Venous thrombotic manifestations (n =13) and large local hematoma (n =3) were detected.The diameter ranges were around (1.8 ± 0.7) cm for arteriovenous fistula and (2.0 ± 0.8) cm for local hematoma.And there was no statistical significance (t =1.63,P ＞ 0.05).According to edge shape,presence or absence of flow signal and fistula searching,it could be used to identify venous thrombosis and local hematoma of arteriovenous fistula.Color Doppler ultrasound is helpful for the differential diagnosis and the mass properties of arteriovenous fistula so that it provides useful diagnostic information for the clinicians.
