摘要 将健康成年杂种犬11只随机分成两组,观察组5只行上、下腔静脉口超声消融,对照组6只行上、下腔静脉口射频环状消融。分别于插管前,插管后,消融后即刻,消融后0.5h、48h取外周静脉血5m l,用发光底物法测定组织型纤溶酶原激活剂(t-PA)及t-PA抑制物1(PA I-1)的变化。结果两组t-PA、PA I-1插管前后无明显变化;t-PA于消融后即刻达高峰,0.5h后开始下降;PA I-1于消融后0.5h达高峰,消融后48h恢复正常;两组比较,t-PA无明显差异,但PA I-1在消融后即刻及消融后0.5h,对照组明显高于观察组。证实超声消融与射频消融均一过性激活纤溶系统,其对凝血系统的激活占优势,且射频消融更明显;超声消融入心静脉口不易形成血栓,较射频消融更为安全。
