The clinical effect of hemihepatic blood flow occlusion in combination with proper hepatic artery temporary occlusion applied to hemihepatectomy

Objective To explore the clinical effects of combining of total hemihepatic vascular exclusion with proper hepatic artery temporary exclusion.Methods From June 2001 to December 2006,the average bleeding volume during operation and liver function grade deterioration after operation were retrospectively analyzed in 35 cases subject to hemihepatic blood flow occlusion combined with proper hepatic artery temporary occlusion applied to hemihepatectomy(group A)vs 36 cases subject to hemihepatic blood flow occlusion alone applied to hemihepatectomy(group B).Results The average bleeding volume in group A and group B was (390±80)ml and (320±50)ml respectively with the difference being significant between them(P0.05).The occurrence of postoperative hepatic function deterioration in groups A and B was 17.1% and 16.6% respectively(P0.05).Conclusion Hemihepatic blood flow occlusion combined with proper hepatic artery temporary occlusion significantly reduces bleeding volume in hemihepatetomy and dose not increase hepatic function grade deterioration occurrence after hemihepatectomy.
