Fig. 5. Application of virtual simulation in performing the superior hypogastric plexus block. (A) Coronal view of the patient’s magnetic resonance image. Metastasis to the right sided L5 vertebra and sacral ala seems to cause the pain. (B) Three-dimensional virtual procedural planning. The virtual needle is placed at the most appropriate position. (C) Oblique view of the virtual X-ray image is saved where the needle presents as a pinpoint. (D) Anteroposterior view of the simulated virtual X-ray. (E) The patient’s oblique X-ray image during the procedure. (F) The patient’s X-ray image in the anteroposterior view during the procedure. White asterisk: needle, TP: transverse process, SAP: superior articular process, Dotted lines: contour of anatomical structures.
