目的探讨二维血流显示(B-Flow)技术在肾衰血透患者动静脉瘘中的应用价值。方法本文对31例尿毒症患者人工动静脉瘘进行超声检查,分别采用CDFI、PDI和B-Flow三种模式显示瘘口和动静脉侧血管情况,着重观察吻合口和动静脉侧血管形态、管壁情况以及管腔内血流显示情况,并进行血流动力学检测。结果本组病例共31例检查对象,端端吻合23例,端侧吻合3例,侧侧吻合2例,人造血管吻合3例。吻合口平均内径5mm。吻合口狭窄6例、血栓形成4例。B-Flow技术能同时清晰显示血流和邻近背景组织,与CDFI、PDI结合使用可提高异常图像显示率。B-Flow与CDFI、PDI比较,具有更高帧频、高分辨力和全景显示功能。结论B-Flow技术是监测血透患者治疗过程中造瘘血管状况的有效的辅助检测手段之一。动静脉瘘主要并发症是吻合口狭窄、静脉段瘤样扩张和血栓形成。
目的探討二維血流顯示(B-Flow)技術在腎衰血透患者動靜脈瘺中的應用價值。方法本文對31例尿毒癥患者人工動靜脈瘺進行超聲檢查,分彆採用CDFI、PDI和B-Flow三種模式顯示瘺口和動靜脈側血管情況,著重觀察吻閤口和動靜脈側血管形態、管壁情況以及管腔內血流顯示情況,併進行血流動力學檢測。結果本組病例共31例檢查對象,耑耑吻閤23例,耑側吻閤3例,側側吻閤2例,人造血管吻閤3例。吻閤口平均內徑5mm。吻閤口狹窄6例、血栓形成4例。B-Flow技術能同時清晰顯示血流和鄰近揹景組織,與CDFI、PDI結閤使用可提高異常圖像顯示率。B-Flow與CDFI、PDI比較,具有更高幀頻、高分辨力和全景顯示功能。結論B-Flow技術是鑑測血透患者治療過程中造瘺血管狀況的有效的輔助檢測手段之一。動靜脈瘺主要併髮癥是吻閤口狹窄、靜脈段瘤樣擴張和血栓形成。

Purpose To explore and understand the practical value with B-Flowin arteriovenous fistula hemodialysis patients with uremia.Methods 31 cases were examined with upper limbs arteriovenous fistulas with uremia and analyzed by CDFI,PDI and B-Flow.It is important to observe conformation of fistula and blood vessel and examine changes on hemodynamics.Results Among 31 patients,23 patients were operated with end-to-end anastomoses,3 cases with end-to-side anastomoses,2 cases with manmade blood vessels.The average diameter of anastomoses orifice is 5mm.Six cases with anastomoses stenosis and 4 cases with thrombus formation.B-Flow technique can display blood flow and background tissue distinctly at the same time.B-Flow include wide bandwidth,high frame rate and high dynamic range for high spatial,temporal and contrast resolution imaging,respectively.Conclusion B-Flow is an effective supplementary detective methods in treating hemodialysis patients with uremia.The main complication involved in is anastomoses stenosis,venus dilatation and anastomoses stricture associated with thrombus happened in individual case.
