The integrated network image printing system can realize rapid transmission and printing for image data,and significantly enhance printing efficiency,which has been a main trend in future development of printing system.In addition,the integrated network image printing system can provide more precise and efficient solution for printing tasks that need process medical imaging,professional photographs or other high-quality images.This study strengthened the process technique on the basis of image denoising and contrast with wavelet transform,which improved the existing integrated network image printing system and tested the improved system.The result indicated that this system can effectively improve image quality.This study summarized the cases of maintaining failure in the application of this system,which target was to provide references for the application of the integrated network image printing systems.

Objective To evaluate the clinical outcome of bleeding control by preoperative embolization of internal iliac artery with DSA and intra?operative presetting abdominal aorta balloon, combine with the operation techniques of exposure, reduc?tion and internal fixation of pelvic fracture through lateral?rectus approach. Methods From March 2012 to May 2015, 7 patients with type C3 pelvic fractures admitted to our department from March 2012 to May 2015, treated with preoperative embolization of internal iliac artery under digital subtraction angiography 2 h before surgery and presetting abdominal aorta balloon were retrospec?tively reviewed. There were 3 males and 4 females, with an average age of 34 years (range, 16 to 61 years). According to AO classi?fication, all 7 cases belonged to type C3 (3.2:5 cases;C3.3:2 cases), including 5 cases with limb fracture, 2 cases with craniocere?bral trauma, 4 cases with pulmonary contusion, 2 cases with injury of abdominsal organs. Time from injury to operation was 19 days on average (10 to 33 days). Patients received damage control surgery treatment including bleeding control and temporary ex?ternal fixation, and ipsilateral tractions with heavy weight, intensive care and corrections of general situation before operation. The fracture model was manufactured by 3D printing and fracture reduction was simulated on computer preoperatively. Embolization of internal iliac artery was performed in the side of severe displaced sacroiliac joint with DSA 2 hours preoperatively. Reduction was performed to stabilize anterior-posterior pelvic ring and acetabular fractures via the intraoperative lateral?rectus approach. And 2 cases were performed by temporary balloon occlusion of abdominal aorta (≤60 min) for bleeding control in reduction of in the side of sacroiliac joint fractures. Results All the 7 cases had undergone the operations successfully, and the operating time was from 135-320 min with blood loss from 440-3 350 ml. According to Matta radiological evaluation postoperatively, reduction of pelvic fracture was rated as anatomic in 5 cases, satisfactory in 2, without complications. All 7 cases were complicated with lumbosacral plexus injury or lumbosacral trunk injury at different degrees (M0 2 cases, M1 2 cases, M2 2 cases, M3 1 case). According to the BMRC scoring system, 5 cases had well recovered and the other 2 cases had no improvement after three months (M4 2 cases, M5 3 cases). Conclusion Surgical management of pelvic fracture through preoperative internal iliac artery embolization and intra?oper?ative occlusion of abdominal aorta could effective control bleeding and achieve favorable conditions for reduction. Lateral?rectus approach can provide adequate exposure of the anterior and posterior ring, and this approach could also provide excellent visual control of reduction and fixation.
