目的探究分析血管CT联合彩色 多普勒超声检查不同成熟程度动静脉内 瘘的临床应用价值。方法 选择2015年6 月-2017年6月期间来院就诊的行造瘘术尿 毒症患者60例作为临床研究对象，所有患 者造瘘术前、后均行血管CT及彩色多普勒 超声检查，比较不同影像学检查方式对患 者可用静脉的选择情况以及患者行造瘘术 治疗后不同时点内瘘管内径、内瘘血流速 度、内瘘血流量变化等动静脉内瘘成熟情 况。结果 血管CT和彩色多普勒超声均可 用于显示可建立动静脉内瘘的静脉，但 血管CT检查对可用静脉数的显示明显低 于采用彩色多普勒超声检查的选择结果 (P<0.05)，组间差异具有统计学意义。接 受造瘘术治疗后4周及8周时，患者内瘘管 内径、内瘘管血流速度以及内瘘血流量均 明显高于术后1周状态(P<0.05)，相较于 术后4周状态，术后8周时患者内瘘管内 径、内瘘管血流速度以及内瘘血流量也明 显增高(P<0.05)，组间差异显著，具有统 计学意义。结论 血管CT联合彩色多普勒 超声检查有助于帮助选择需行人工动静脉 造瘘术患者的手术静脉，同时在辅助评估 造瘘术后患者的动静脉瘘成熟情况中也具 有重要意义。

Objective To explore the clinical application value of analysis of vascular CT combined with color doppler ultrasonography to examine the use of intravenous fistula in different maturation. Methods A total of 60 patients with uremia who came to the hospital in June 2015-2017 June were selected as clinical subjects, all patients underwent vascular CT and color Doppler ultrasonography before and after ostomy. The choice of the available vein for patients with different imaging methods and the internal fistula internal diameter of the internal fistula, the velocity of internal fistula blood flow and the change of internal fistula blood flow were compared. Results The blood vessels CT and color doppler ultrasound can be used to demonstrated arteriovenous fistula of the vein, but the vascular CT examination usable vein number was lower than that using the choice of color doppler ultrasound examination results (P<0.05), statistically significant difference between the groups. Accept colostomy at 4 weeks and 8 weeks after treatment, patients with fistula in diameter, internal fistula blood flow velocity and internal fistula state of blood flow were significantly higher than that of postoperative 1 week (P<0.05), compared with 4 weeks after surgery, postoperative 8 weeks in patients with fistula diameter, internal fistula blood flow velocity and internal fistula blood flow also increased significantly (P<0.05) and significant difference between groups, with statistical significance. Conclusion Vascular CT combined with color Doppler ultrasonography is helpful to select the operating veins of patients who need to be operated by artificial arteriovenous fistulas, and it is also of great significance in assisting the assessment of arteriovenous fistula maturity in patients after stomaostomy.
