超声造影在移植肾血管并发症中的应用

目的 探讨超声造影技术在移植肾血管并发症中的应用价值.方法 对12例肾移植未后血管异常患者的超声造影图像进行观察与分析,全部病例经手术、病理或血管造影证实.结果 移植肾动脉狭窄5例,肾动脉血栓2例,假性动脉瘤3例,假性静脉瘤1例,肾内广泛微血栓1例.12例移植肾血管并发症的超声造影符合率达100%.结论 超声造影无肾毒性损害,是一项很有潜力的诊断移植肾血管并发症的方法 .

Application of contrast-enhanced ultrasound in the diagnosis of vascular complications of renal transplantations

Objective To evaluate contrast-enhanced ultrasound(CEUS) in the diagnosis of vascular complications of transplanted kidneys.Methods Twelve patients with vascular abnormalities after renal transplantation were observed and analyzed using CEUS, and the diagnosis of all cases was confirmed by means of operation,pathology or angiography.Results Five patients with renal artery stenosis,2 patients with renal artery thrombosis,3 patients with pseudoaneurysm, 1 patient with pseudophlebangioma, and 1 patient with intrarenal extensive microthrombus were found.The coincidence of CEUS was 100%.Conclusions CEUS is a new method with the characteristics of non-nephrotoxic damage to kidney and comparable with angiography in terms of dynamic imaging.
