The Application Of Multislice Spiral Computed Tomographic Angiography (MSCTA) In The Evalution Of Pelvis Tumor

Objective:To evaluate the effect of multislice spiral computed tomographic angiography (MSCTA) and it subsequent processing in preoperative of pelvis tumor assessment.Materials and methods:eleven patients with pelvic tumors from 2007 to 2011 were scanned by 64-section CT and reconstructed with volume rending (VR) and maximum intensty projection (MIP) before operation and assessed tumor area and the information of tumor vessels compared to surgical results. Operation time, the volume of bleeding, blood transfusion, and changes of electrolyte, RBC/HBG before and after operation were recorded in the groups.Results:four cases with bilateral internal iliac artery ligation, one case with unilateral internal iliac ligation, one case with abdominal aorta block, one case with arteria iliaca communis block and two cases with abdominal aorta block + bilateral internal iliac artery ligation.The operation time was (197±62) minutes, the volume of bleeding and blood transfusion were (2927±1488) ml and (2172±1572) ml.The blood electrolyte and RBC/HBG had no obvious differences before and after operation, the visual analogue scale (VAS) of average pain before and after operation were (5.18±2.35) and (1.54±1.12)(P<0.05), that was statistically significant.Conclusion:The MSCTA and it subsequent processing provide more clear image on the details of pelvic tumors, which can stereoscopically, easily, understandably display the relationship between the lesion and surrounding structure, so it can help clinical doctors for accurate diagnosis and making operation plan.
