Analysis of hepaticarterial blood supply to hepatic tumor in segment IX by DSA

Abstract

：Objective To study thehepatic arterial blood supply to the hepatic tumor in segment IX.Methods CT and DSA imagesof 8 patients with hepatic tumors in segment IX were retrospectively analyzed.The locationof tumor was diagnosed on CT.The hepatic arterial blood supply of the tumors was surveyedon DSA.The branches of hepatic artery were observed at different levels.The cases of eachhepatic artery branch supplying to the tumor were accounted.Therefore,the blood supplyingartery branches of hepatic tumor in segment IX were revealed and analyzed.Scoring wasemployed to quantify the blood supply of the hepatic artery branches.Results There wereseveral branehes of hepatic artery supplying to the tumor in segment IX.The number ofcases in which the tumors were supplied by MHA,RPHA,RAHA.LMHA and CaHA was 7,6,5,5 and2,respectively(X2=2.800,P=0.592,Chi-square test).The scores of MHA,RPHA,RAHA,LMHA and CaHAwere 15,13,11,6 and 2,respectively(X2=9.657,P=0.047,Kendall's W).The total scores of RHAand LHA system were 38 and 9(Z=-2.243.P=0.025,Wilcoxon).No tumor was supplied by CyA orLLHA in these cases.Conclusion Either RHA or LHA system is possible to supply blood to thetumors in segment IX of 1iver.The blood supply from RHA is more than that fromLHA.MHA,RPHA,RAHA and LMHA are the main arteries supplying to the tumor.
