Complete regeneration of large bone defects in rats with commercially available fibrin loaded with BMP-2.
In conclusion, commercially available fibrin is a very efficient carrier for rhBMP-2 to graft critical-size cortical bone defects and might be a more optimal delivery vehicle for BMP-2-induced bone regeneration than currently available collagen sponges. PMID: 31529455 [PubMed - in process]
ConclusionAs PDH can lead to major and life threatening complications, it must remain in our minds as a possible cause of intestinal obstruction.
The objective of this study was to analyze the utility of cone beam computed tomography (CBCT) for technical assessment of standard and complex endovascular aneurysm repair (EVAR).
man P Abstract BACKGROUND: The Fontan procedure is performed in patients with congenital heart diseases and abnormal anatomy which preclude intracardiac repair separating the systemic and pulmonary circulation. The role of computed tomography (CT) imaging in assessing patients after total cavopulmonary connection (TCPC) is not well defined. AIMS: Aim of the study was to determine potential role and capability of CT imaging in functional assessment of adults after TCPC. METHODS: Data of eighteen patients (10 women, mean age 27.9±6.3 years) after TCPC procedure were retrospectively analyzed. All und...
Abstract Femoroacetabular impingement is a cause of hip pain in young adults as a result of premature dynamic contact between the femur and acetabulum that occurs within the physiological range of hip motion. Diagnosis is made by patient history, clinical examination and radiographic findings. Cross-sectional imaging with computed tomography and magnetic resonance arthrography may be necessary in selected patients. Femoroacetabular impingement can be treated non-operatively with physiotherapist-led conservative care including analgesia and intra-articular steroid injections. Arthroscopic hip surgery aiming to rest...
Conclusion: The zygomaticosphenoidal angle is a useful reference, in conjunction with stereotactic navigation, for reduction of zygomaticomaxillary complex fractures. Contralaterally obtained patient-specific data may be used to guide unilateral repair. Normative values may serve as reference in bilateral injury.
In conclusion, intraoperative CT allows real-time assessment of fracture reduction and immediate orbital implant revision, especially at posterior ledge. As a result, no postoperative imaging was indicated in any of the patients. Long-term follow-ups for orbital fracture patients managed with intraoperative CT is suggested.
Abstract In recent years, the prevalence of invasive Streptococcus dysgalactiae subsp. equisimilis (SDSE) infections has increased gradually throughout the world, including Japan. Here, we report the case of an abdominal aortic graft infection caused by stG485.0, ST29 SDSE in an elderly patient with diabetes. An 86-year-old man who had undergone an abdominal aortic aneurysm (not infected) repair with a bifurcated graft 10 years ago was referred to our hospital after being suspected of having abdominal aortic graft infection through computed tomography. He underwent surgery, and the pus developed between the aneury...
CONCLUSIONS AND CLINICAL RELEVANCE: Articular surface models derived from CT images had dimensional errors that approximately matched the voxel size. Thus, CT cannot be used to plan conforming arthroplasties in small joints and could lack precision when used to plan the correction of a limb deformity or repair of a fracture.

CONCLUSIONEven if rarely symptomatic, the Spigelian Hernia is an entity to consider in the differential diagnosis of small bowel obstruction in a virgin abdomen. Preoperative diagnosis, when available, is mandatory to guide a correct surgical approach.
The dynamic endovascular environment of stent grafts may influence long term outcome after endovascular aneurysm repair (EVAR). The sealing and fixation of a stent graft to the aortic wall is challenged at every heartbeat, yet knowledge of the cardiac induced dynamics of stent grafts is sparse. Understanding the stent –artery interaction is crucial for device development and may aid the prediction of failure in the individual patient. The aim of this work was to establish quantitative stent graft motion in multiphasic electrocardiogram (ECG) gated computed tomography (CT) by image registration and segmentation techniques.
