In order to explore the imaging diagnosis methods and interventional treatment effects of
hepatocellular carcinoma combined with hepatic
arteriovenous fistula (HAVF), a total of 120 patients, who were diagnosed as hepatic
carcinoma with arteriovenous shunting and underwent medical imaging diagnosis and interventional surgery
therapy at a designated hospital by this study from December 2014 to December 2018, were chosen as study subjects. Digital subtraction angiography was performed to analyze the imaging features of
hepatocellular carcinoma combined with HAVF in each patient; then, according to these imaging diagnosis results,
gelatin sponge or coil was used to block the
fistula;
mitomycin,
carboplatin powder, and
lipiodol mixed
emulsion was combined or separately utilized for hepatic
tumor embolization, in which
iodized oil embolization
chemotherapy was used for patients with mild
paralysis;
gelatin sponge granule embolization
chemotherapy was used for moderate
paralysis patients at their first intervention, and, after about 1 month, if the sputum disappeared,
iodized oil embolization was used again; and hepatic arterial infusion
chemotherapy was used only for patients with severe
paralysis. The results show that the central type of HAVF is characterized by early angiography of portal vein and large branches and
tumor staining after portal vein's angiography; the peripheral type of HAVF is characterized by portal vein branching in hepatic
tumor and double rail sign accompanied by the arterial branch; 112 cases of patients completed embolization
chemotherapy; 8 cases of patients only received
chemotherapy perfusion; in 109 cases of patients sputum disappeared or shunt decreased at first treatment; and in 113 cases of patients
iodine oil was well deposited or the
tumor was stably reduced; most of the symptoms of refractory
ascites,
diarrhea, and upper gastrointestinal
bleeding were controlled or improved, and there were no complications such as
pulmonary embolism and
hepatic failure. Therefore, HAVF increases the difficulty of interventional
therapy, but, as long as the positive and appropriate treatment measures are taken, it can still achieve better curative effect without serious complications, which can effectively alleviate the clinical symptoms of patients and improve the quality of life of patients. The results of this study provide a reference for the further researches on imaging diagnosis and interventional treatment for
hepatocellular carcinoma combined with
arteriovenous fistula.
