Objective To assess the diagnostic value of DSA for nontumorous arterioportal shunt in cirrhosis.Methods One hundred seventy cirrhotic patients without HCC under going transhepatic artery self bone marrow stem cell transplantation were taken liver arterial DSA together with 165 CT data.Arterioportal shunt(APS)appearance phase,persisting time and characteristics of liver parenchyma staining caused by APS were analyzed dynamically.Small HCC was differentiated from nontumorous APS.TACE procedure was done when HCC lesion was confirmed by DSA findings.Results 31.7%(54/170)DSA presented the sign of APS. Among the 142 cases with no evidence of APS on CT examinations,but APS was seen in DSA of 31 cases (21.8%).All patients with CT findings of liver abnormal enhancement of APS,23 cases including 16 cases as nontermorous and 7 cases whose CT arterial phase showing local persistant enhancement without declination in portal venous phase which were recognized to be HCC later by DSA characteristics with only one having tumorous APS.Conclusions DSA has a comparative high visualization rate of nontumorous APS in liver cirrhosis and benefits the differentiation with malignant lesions guiding the interventional procedure.
