摘　　要：62例自体动静脉瘘行彩色多普勒超声检查中，13例有静脉血栓表现，3例为较大的局部血肿表现。静脉血栓增宽的内径范围约（1．8±0．7）cm，而局部血肿增宽的内径范围约（2．0±0．8）cm，两者内径增宽没有统计学意义（t=1．63，P〉0．05）。根据边缘形态、是否有血流信号及瘘口等影像特征，可鉴别血液透析动静脉内瘘静脉血栓形成和局部血肿，为临床医生提供可靠的诊断依据。A total of 62 cases with autogenous arteriovenous fistulas were examined by 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.
