| 目的：回顾性分析106例自体动静脉內瘘(autogenous arteriovenous fistula,AVF)血流量不足的持续性血液透析患者超声诊断特点。方法：对106例AVF血流量不足的血液透析患者进行超声检查,二维超声观察供血动脉、吻合口、引流静脉的管径、管腔内有无血栓形成、其周围有无血肿及侧支静脉扩张等情况；彩色多普勒超声检测管腔内血流充盈情况、血流方向及流速。结果 106例AVF血流量不足的患者中,超声显示上肢引流静脉管腔狭窄67例(54.5％),上肢引流静脉血栓24例(19.5％),吻合口狭窄23例(18.7％),中心静脉狭窄或栓塞5例(4.1％),供血动脉狭窄2例(1.6％),吻合口周围软组织内血肿1例(0.8％),手背静脉网血管增多、增粗1例(0.8％)。结论：彩色多普勒超声检查有助于诊断血液透析AVF血流量不足病因,具有较高的临床应用价值。 |

| Abstract: |
| To retrospectively analyze the characteristics of ultrasonogaphy of 106 cases of flow insufficiency of autogenous arteriovenous fistula （AVF） in hematodialysis patients. Methods Ultrasonography was performed in 106 cases of AVF flow insufficiency in hematodialysis patients，in which the feeding arteries，the anastomotic stomas，the draining veins and the collateral circulation were evaluated by gray-scale ultrasonography and the blood filling，direction and velocity in vessels were evaluated by ultrasonic Doppler imaging. Results Among the 106 cases of AVF flow insufficiency，ultrasonography showed stenosis of draining veins of upper limb in 67 cases （54.5%），thrombosis of draining veins of upper limb in 24 cases （19.5%），anastomotic stenosis in 23 cases （18.7%），stenosis or embolism of central veins in 5 cases （4.1%），stenosis of feeding arteries in 2 cases （1.6%），hematoma of the soft tissue around anastomotic stoma in 1 case （0.8%），and increased dorsal venous rete of hand in 1 case （0.8%），respectively. Conclusion Ultrasonography has definite clinical value that it helps to diagnose the causes of AVF flow insufficiency in hematodialysis patients. |
