Study Of Medical Imaging To Pelvic Tumors Feeding Artery

Objective:To more effectively guide clinical application for selective arterial infusion and embolization of the pelvic tumor feeding artery by statistically analyzing its origin and composition.Methods:Abdominal imaging data was collected from55pelvic tumor patients. According to the condition of patients, volumetric representation.(VR) was used to carry out CTA vascular reconstruction;3D-TOF and MPR (multi planar reconstruction) were applied to MRA vascular reconstruction; DAS imaging displayed the pelvic tumor feeding artery.Results:Among the12cases of ovarian tumors, the research shows5cases of ovarian artery (OA) and ovarian branch artery (OB) supply blood together,5cases of OA blood supply and2cases of OA blood supply. Among the11cases of exogenous uterine fibroids, bilateral uterine artery branch (UB) supply blood in all16lumps;3cases of OA are also involved in blood supply; sigmoid arteries supply blood in all7cases of sigmoid colon cancer. Of the9cases of rectal cancer are3cases of upper rectal artery blood supply,5cases of upper and under rectal artery blood supply and1case of upper and under rectal artery together with median sacral artery blood supply. Uterine arteries supply blood in all7cases of pelvic metastases;2cases of OA are also involved in blood supply. Bladder arteries supply blood in all9cases of bladder cancer.Conclusion:The feeding arteries for pelvic tumor are diverse, mainly including ovarian artery, uterine artery, uterine artery branch, ovarian branch, sigmoid artery, upper and under rectum artery, bladder artery and median sacral artery. Blood can be supplied by each artery alone or together. Therefore it is necessary to fully check the feeding artery before conducting selective arterial perfusion and embolization in interventional treatment.
