Guidance of Multislice Helical Computed-tomography Angiography of Abdomen in Interventional Operation of Liver Tumors

Objective:Investigate the value of the multislice helical computed-tomography angiography used before the interventional operation of the fiver tumors.Materials and Methods:37 cases liver tumors were made angiographies by MSCT before they were interventional operated.The angiographies pictures could display the position of abdomen blood vessel,the branch of blood vessel,and the relation of vessel and tumor.And these could guide the interventional operation. Results:16 cases of the norm coeliac trunk artery were displayed by MSCTA.9 cases of the coeliac trunk artery location were misregistration.4 cases superior mesenteric artery,debounch from celiac trunk.2 cases coelical trunk artery were imperforation.32 cases clear displayed the coelical trunk artery,common hepatic artery,proper hepatic artery and left and right hepatic artery.29 cases displayed tumor feeding artery,2 cases display mutation feeding artery.Conclusion:With the guidance of MSCT angiography,the time of interventional operation decreased and it got easy to intubate.MSCT angiography of abdomen was valuable to guide the liver tumor interventional operation.
