超微血流成像术用于肾移植患者术后评估的临床价值分析

Analysis of the Clinical value of Ultramicro-flow Imaging for the Postoperative Evaluation of Renal Transplant Recipients

目的:探讨超微血流成像术用于肾移植患者术后评估的临床价值。方法:选取我院2019年2月-2019年8月收治的60例肾移植患者的临床资料,根据术后恢复情况分为A、B、C三组,A组(27例,术后肾功能恢复良好)、B组(20例,术后发生过敏肾功能异常病变但治疗后肾功恢复正常)、C组(13例,术后血肌酐水平持续增高肾功能异常者),三组均采用超微血管流成像术检测血管指数,比较不同组患者的血管指数并分析其与血肌酐水平的关系。结果:三组患者的肾移植长径、前后径、左右径、皮质厚度、叶间动脉阻力指数比较无显著差异(P>0.05)。C组患者的肾皮质血管指数(23.34±6.03%)明显低于A组(33.23±3.45%)、B组(31.23±4.23%)(P<0.05)。肾功能异常患者肾皮质的血管指数较低,且随着血肌酐水平的升高而下降,两者呈显著负相关(r=-0.23,P<0.05)。结论:超声微血流成像术用于肾移植患者术后评估可较好地反映肾皮质血供及术后肾功能的变化。

Objective: To evaluate the feasibility of ultramicro-flow imaging for the postoperative evaluation of renal transplantation patients. Methods: The clinical data of 60 renal transplant patients admitted to our hospital from February 2019 to August 2019 were retrospectively analyzed. According to the recovery after operation, they were divided into three groups: A, B and C. Group A(27 cases had good recovery of renal function after operation) and Group B(20 cases with abnormal allergic renal function after operation, but recovery of renal function after treatment), group C(13 patients with postoperative serum creatinine levels continued to increase renal dysfunction). All three groups used ultra-microvascular flow imaging was used to detect vascular index, and the vascular index of different groups was compared and analyzed for its relationship with serum creatinine level. Results: There were no significant difference in the length, anterior and posterior diameters, left and right diameters, cortical thickness and resistance index of interlobar artery between the three groups(P>0.05). The renal cortical vascular index in the group C(23.34±6.03%) was significantly lower than that in the group A(33.23±3.45%) and the group B(31.23±4.23%)(P<0.05). The renal vascular index of renal dysfunction was lower, and it decreases with the increase of serum creatinine level, which was negatively correlated between them(r=-0.23, P<0.05). Conclusion: Ultrasound micro-blood flow imaging for postoperative evaluation of renal transplant patients can better reflect changes in renal cortical blood supply and postoperative renal function.
