Objective To observe the blood circulation compensation in the involved area of the liver following ligation of the third grade branches of hepatic artery and portal vein and bile duct enclosed in Glisson’s capsule.
Methods Ligation of the third grade branches of these ducts was carried out in 7 pigs. Uptake of 99mTc-EHIDA in the liver was scanned with SPECT pre-and post-operatively. Liver angiography of hepatic artery and portal vein were taken at regular interval. Corrosion casts of these ducts were made with ABS following extirpation of the liver at the end of experiment. The histological specimens were examined with electronic microscope.
Results Compensatory circulation occurred between involved and noninvolved part of the liver through the sinusoids in 30-60 minutes after ligation. In the 6 weeks following the procedure, there was also blood supply in the affected region of liver, and collateral developed through hepatic aterioles and capillaries.
Conclusion Liver has an ability to establish compensatory blood supply on the condition of ischema in a local region of liver.
