Saphena varix is very rare disease that characterized by isolated distention of the saphenous vein below the sapheno-femoral junction. Saphena varix must be differentiated from other medical problems that can cause a groin mass. A 49-year-old man presented with a palpable mass on the right upper thigh and he'd had the mass for 6 months. There was no history of trauma, and the mass was especially noticeable when he was standing. On the physical examination, a 5 cm-sized soft, nontender, compressible mass was detected at the right upper medial thigh near the femoral foramen. Doppler sonography showed a saccular venous dilatation of the great saphenous vein just below the saphenofemoral junction. On computed tomography, there were superficially dilated veins in the right thigh and calf, a focal saccular aneurysm at the proximal segment of the right greater saphenous vein and no evidence of deep vein thrombosis. Aneurymal excision and stripping of the greater saphenous vein were performed. No complication was observed at the 2 week follow-up.

The aim of this project was to use 3D scanning data collected at incident scenes and various evidence to 1) develop surveying methods based on 3D data consisting of overall and detailed scene evidence, captured by long-range and micros-canner, which can be shared by personnel working in different fields such as forensic medicine, video analysis, physical analysis, traffic engineering, and fire investigation; 2) create digital storage for human skeletons and set the foundation for virtual anthropology; and 3) improve the credibility of 3D evidence by virtual remodeling and simulation of incident scenes and evidence to provide a basis for advanced and high-tech scientific investigation. Two complete skeletons of male and female were scanned using 3D micro-scanner. Each bone was successfully reproduced and assembled in virtual space. In addition, recreating evidence scheduled for invasive examination by creating RP (rapid prototype) was possible. These outcomes could play an important role in setting up the new field of virtual anthropology. Case-specific surveying methods were developed through analysis of 3D scanning data collected by long-range surface scanners at the scenes of vehicular accidents, falls, shootings, and violent crimes. A technique and recording method was also developed for detecting forged seals by micro-scanning the pressure exerted on the seal. Appraisal methods developed in this project could be utilized to secure 3D data of human skeletal remains and incident scenes, create a standard for application, and increase objectivity, reproducibility, and accuracy of scanning methods. We plan to develop case-specific 3D data analysis techniques to improve the credibility of analysis at the NFS and to establish a 3D data collection and analysis team.
