Changjiang Business Daily, December 24, 2014. Wuhan Sixth Hospital (Jianghan University Hospital), director of the Department of Nail and Breast Surgery, Li Rong, saw such a patient in the specialist clinic: 71-year-old Granny Shi, who had a large tumor on her neck, was found to be connected to the jugular vein by CT-enhanced examination, a rare case of jugular vein tumor with internal thrombus formation, and the thrombus was at risk of wandering at any time to cause fatal pulmonary embolism. The tumor of Shi’s mother-in-law is like a “time bomb”, one is adjacent to the submandibular gland and the cervical plexus, if there is a mistake during the operation, it will lead to salivary leakage and sensory impairment; the second is that the vein wall is very thin, if there is a mistake during the operation, the tumor may rupture, and once it ruptures, it may cause a fatal air embolism. Two “ifs” were placed in front of Director Li, which made him extremely cautious. Director Li Rong invited Director Wang Xiaoyan from the CT room to consult with him, and they made a realistic 3D reconstruction model through 64-row multi-layer spiral scan, and carefully studied on this model to design the operation plan, and finally operated successfully according to this. Director Wang Xiaoyan of the CT room introduced that after the CT scan, a three-dimensional image of the surgical site is created by computer to realistically restore the local anatomical structure. In the past, the patient’s CT scan was a flat screenshot, and the doctor could only restore it to a three-dimensional image in his head, while the three-dimensional reconstruction model system allows the doctor to see the contour shape and structure of the surgical site before the operation, like GPS navigation for the operation. For complex conditions can help doctors make accurate judgments, which can improve the adoption rate and success rate of surgery. More importantly, with the help of the simulation system, accurate resection can be achieved, and the diseased tissue can be removed more cleanly to minimize surgical misuse of surrounding normal tissues and organs, and also reduce the probability of massive blood loss during surgery and reduce complications and postoperative recurrence rate.
