Abstract:
Objective To establish rabbit model bearing VX2 liver tumor using improved technique,and to analyze the relevant impact factors of hepatic artery and portal vein catheterization.Methods Transplanted liver tumors of 60 healthy New Zealand white rabbits were established through open abdominal puncture and hepatic artery and portal vein catheterization.The rabbits were divided into A group (survival) and B group (death) according to whether a short-term (within 7 days after surgery) death occurred or not.The univariate analysis of the factors which could lead to the death of rabbits were analyzed.The Logistic regression models were established with parameters which were significantly different between the 2 groups,and independent risk factors which could lead to the failure of the experiment were analyzed.Results VX2 tumors were successfully implanted in the liver to all 60 rabbits.Nine (9/60,15.00 %) rabbits died within 7 days,while 51 (51/60,85.00%) rabbits survived,weight < 2.5 kg,additional intraoperative anesthesia,operation time ≥60 min,length of incision ≥5 cm and blood loss of operation ≥25 ml were impact factors (all P<0.05).Weight < 2.5 kg,additional intraoperative anesthesia and the blood loss of operation ≥25 ml were independent risk factors for death (P<0.01).Conclusion Relative high success rate of building rabbit models bearing VX2 liver tumor may achieved using hepatic artery and portal vein catheterization.Larger weight of rabbits,training of surgical skills,less intraoperative blood loss are helpful to avoid intraoperative additional anesthesia,thus reducing mortality of rabbits.
