【摘要】 目的探讨舒张期反向血流RI及收缩期峰值流速与舒张末期流速比(S/D)在移植肾中的价值。方法 22例移植肾患者出现舒张期反向血流,其原因包括急性排斥(12例),肾小管坏死(5例),肾动脉血栓(1例),肾静脉血栓(2例),感染(2例)。根据22例移植肾舒张期反向血流患者保。肾是否成功将其分为手术组(4例)和非手术组(18例),对其RI和S/D比值进行统计学处理。结果手术组RI高于非手术组(P=0.041),手术组S/D值低于非手术组(P=0.048)。结论移植肾舒张期反向血流RI,S/D值有助于判断移棺肾预后。更多还原

【Abstract】 Objective To study the significance of resistance index (RI) and systolic/diastolic ratio (S/D ratio) in reversed diastolic flow in renal allografts. Methods Rversed diastolic flow was found in 22 patients. The cause of reversed diastolic flow was acute rejection (n=12), acute tubular necrosis (n= 5), arterial thrombosis (n=1), venous thrombosis (n=2) and infection (n=2). Acoridng to the operation falied or not, 22 patients were classified into two groups:surgical group (n=4) and non-surgical group (n=18). Results Statistical analysis revealed that RI in surgical, group was higher than that in non-surgical group (P= 0. 041), and S/D ratio in surgical group was lower than that in non-surgical group (P=0. 048). Conclusions RI and S/D ratio in reversed diastolic flow may help to judge the prognosis in renal allografts.更多还原
