[Application value of Revolution CT combining three-dimensional visualization technique in precision resection of hepatic alveolar echinococcosis].

OBJECTIVE: To explore the application value of Revolution CT combining three -dimensional visualization technique in the precision resection of hepatic alveolar echinococcosis. METHODS: Totally 12 patients with surgical treatment and pathologically confirmed hepatic alveolar echinococcosis in Qinghai Provincial People's Hospital were retrospectively analyzed. All the patients underwent the Revolution CT plain and enhancement scan before surgery, and the 0.625 millimeter scan data were obtained. The DICOM format data were imported into MI-3DVS for three-dimensional reconstruction, simulated cutting, volume measurement, and surgical planning. RESULTS: The data of 12 patients were reconstructed successfully, and the sizes and locations of the lesions as well as the hepatic vascular systems were clearly displayed. The liver volume, hydatid volume, simulated resection volume, and residual liver ratio were measured accurately. The average whole liver volume and the lesion volume of the 11 surgical treated patients were (2 429.8 ± 335.9) mL and (919.6 ± 262.8) mL respectively. The average actually removed volume was highly associated with the average simulated resection volume (r = 0.979, P < 0.01). CONCLUSIONS: Revolution CT combining three-dimensional visualization technique can achieve accurate diagnosis as well as optimal surgical planning before operation, which is of great value for the precision resection of difficult hepatic alveolar echinococcosis.
