Application value of multi-slice spiral CT angiography in liver cancer patients interventional treatment

Objective To investigate the application value of multi-slice spiral CT angiography (MSCTA) in liver cancer patients interventional treatment.Methods Fifty-four liver cancer patients were selected,all patients underwent MSCTA examination,after the image post-processing,and with 17 cases of patients with the same period digital subtraction angiography (DSA) examination results for comparison,in order to analyze the application value of MSCTA in liver cancer patients interventional treatment.Results The patients with liver cancer were seen MSCTA arterial phase varying degrees of tumor staining,2 cases had hepatic arteriovenous fistula.Some patients in the portal vein and hepatic vein were found vein tumor thrombus.MSCTA showed 10 cases of hepatic artery variation,variation rate of 18.5％ (10/54),in line with the DSA rate of 100.0％.MSCTA showed 11 rami liver cancer parasitic artery,1 case of DSA was not found for the right phrenic artery of liver cancer,there was no significant difference in showed liver cancer parasitic artery between the two methods (P ＞ 0.05).Conclusion MSCTA as a minimally invasive diagnostic method of tumor blood supply,can clearly show the origin of the hepatic artery and its branches and walk the line,liver cancer feeding artery,liver cancer parasitic artery with DSA showed highly consistent results,interventional treatment of liver cancer with important guiding significance.
