【摘要】 目的 探讨多排螺旋CT行CT灌注(CTP)成像和彩色编码DSA(ccDSA)成像在评估兔后肢急性缺血-再灌注(I- R)损伤中的诊断和临床应用价值。方法 50只新西兰大白兔随机分为实验组(n=40)和对照组(n=10)。兔右后肢缺血3 h后,实验组接受再灌注,对照组仅作假手术;分别在0、6、12、24 h作双后肢影像学评估(n=10)。实验组每一时点进一步随机均分为CTP亚组和ccDSA亚组,分别获取双后肢CTP相关参数血流量(AF)、血容量(BV)、对比剂清除率(C)和ccDSA参数对比剂峰值(peak),计算双后肢各参数比值AF- R/L、BV- R/L、C- R/L和peak- R/L;检测血清肌酸激酶(CK)、乳酸脱氢酶(LDH)、丙二醛(MDA)、超氧化物歧化酶(SOD)并分别与AF- R/L、BV- R/L、C- R/L、peak- R/L比值作相关性分析,对AF- R/L与peak- R/L作相关性分析。结果 再灌注过程开始后,AF- R/L、BV- R/L、C- R/L、peak- R/L平均比值分别由1.07±0.08、1.03±0.06、0.93±0.15和1.09±0.04下降至0.75±0.11、0.85±0.14、0.71±0.18和0.45±0.08。AF- R/L与CK、LDH、MDA、SOD血清水平间相关系数分别为-0.60、-0.44、-0.62、0.57(P<0.05);peak- R/L与CK、LDH、MDA、SOD血清水平间相关系数分别为-0.68、-0.71、-0.66、0.59(P<0.05),与AF- R/L间相关系数为0.70(P<0.05)。结论 320排螺旋CT行CTP成像与ccDSA成像,均可在一定程度上量化反映兔后肢骨骼肌I- R损伤发生及严重程度。
