Abstract:

        Objective: To explore the method for constructing the model of vascular network of uterus with cervical cancer and discuss its clinical significance. Methods: A set of specimens, including uterus, vagina and uterine adnexa from a cervical cancer patient were infused with 15% perchloroethylene through the uterine artery and the ovarian artery, and then casted. The CT data of the specimen obtained before and after infusion were used to reconstruct 3D uterine arterial network, using the maximum intensity projection (MIP) and volume rendering (VR). Results:(1) The cast specimen and 3D model of uterine arterial vascular network can clearly display the major blood supply of diseased region. (2) The imaging features and anatomical structures of the uterine vascular network could be shown through different points of view on the reconstructed model.  Conclusions: It is an effective way to construct vascular network of uterus through vascular cast combined with CT scan. Basing on the uterine arterial vascular network of cervical cancer patient, we can understand the size of the lesion and its blood supply, which is useful for the diagnosis and treatment of cervical cancer.
