Applications of three-dimensional visualization technology in individualized diagnosis and treatment oh hepatic hemangioma / 实用医学杂志

ABSTRACT

Objective To investigate the values of three-dimensional visualization technology in the diagnosis and surgical treatment of hepatic hemangioma. Methods Thirty two patients with hepatic hemangioma who had been hospitalized during the period from July 2010 to January 2014 in our hospital were scanned by 64-slice spiral computerized tomography (CT) before surgical treatment. Three-dimensional (3D) reconstruction based on the CT data was carried out to achieve dignosis and surgical planning. Assisted with the 3D model , we chose the best surgical procedure for liver resection, protecting the major blood vessels near hemangioma and retaining normal liver tissue as far as possible. Results The location, size and shape of hepatic hemangioma, vascular variation, and spatial relationship with intrahepatic vessel were shown factually by three-dimensional reconstruction. All the hemangiomas were preoperatively assessed to be resectable. The compliance rate for preoperative surgical planning to actual surgery was 100%. Under assistance of the 3D model during surgery , 14 patients received laparoscopic hepatectomy and 18 underwent hepatectomy. Pringle′s maneuver was applied in 18 patients , with blocking time of (15.32 ± 7.12) min and blood loss of (188.63 ± 66.37) mL. The postoperative complications included pleural effusion in 5 patients and incision infection in one patients. Conclusions Three-dimensional visualization technology for the individualized diagnosis and treatment of hepatic hemangioma helps reduce surgical trauma and incidence of postoperative complications.
