Isolated resection of bemangioma in the cau-date lobe is challenging due to the surgical anatomy of caudate lobe. The caudate lobe consists three portions: Spiegel's lobe, paracaval portion and caudate process. Most of the blood supply of caudate lobe is provided by the posterior segmental branches of the portal vein and left hepatic artery. The hepatic venous drainage encompasses a few sizable and several small branches that join the inferior vena cava. Selection of the ideal route for bepatectomy, adequate mobilization of the liver, preparatory placement of band for hepatic vascular occlusion are key factors during the operation.

Objective To study the effect of flee radical on kidney repedusion injury caused by infra-renal abdominal aorta occlusion in rat model and its possible mechanism. Methods Forty-two healthy Wis-ter rats were randondy divided into 6 groups as following ( n = 7) : the control group( sham group) ; simply isehemia 5 h without reperfusion( group I) ; 2 hours reperfusinn following ischemia 5 h ( I/R 2 h), 4 honrs reperfusion following isebemia 5 h ( I/R 4 h), 8 hours reperfusinn following ischemia 5 h( I/R 8 h) and 12 hours reperfusion following ischemia 5 h ( I/R 12 h). In each group the rats were killed to obtain samples of blood and kidney at the specified time points. The contents of BUN, Cr, MDA, SOD in blood and in renal homogenate were measured in each group. We observed the morphological changes of kidney and muscles of lower limb by light microscope. Results BUN level of serum in model group I, I/R 2 h, I/R 4 h, I/R 12 h were higher obvionsly than those of control group, which were maximal in I/R 4 h, then decreased. MDA level of plasma in model group I, I/R 2 h, I/R 4 h, I/R 8 h, I/R 12 h groups were higher obvionsly than those of control group, which were maximal in I/R4 h group, then decreased. SOD level of plasma in model I/R 4 h, I/R 8 h groups were lower obviously than those of control group; SOD level of renal homogenate in model group I, I/R 2 h, I/R 8 h, I/R 12 h groups were higher obviously than those of group I/R 4 h, which were minimal in I/R 4 h group, then increased. By light microscope: The injury degree of kidney and muscles of lower limb in ischemia group was slight, the injury degree of repedusion group was severer than ischemia group. Conclusion The kidney repedusion injury caused by infrarenal abdominal aorta occlusion in rat model might be concerned with the increase of lipid peroxidatian damage after ischemia-repedusion in-jury of lower limbs.
