Background. The adoption of technical variant grafts has expanded the donor pool for pediatric liver transplantation, but it also poses a risk of portal vein thrombosis (PVT). This study evaluated risk and prognostic factors of PVT in children undergoing liver transplantation with technical variant grafts. Methods. A total of 3137 pediatric patients from 19 centers were included: 470 received split/reduced deceased donor grafts and 2667 received living donor grafts. Multivariable logistic regression was used to identify risk factors, whereas time-dependent Cox models were used to assess the impact on survival. Results. PVT occurred in 102 patients (3.3%) and was associated with increased mortality (adjusted hazard ratio, 2.86; 95% confidence interval [CI], 1.13-7.25; P = 0.027) and graft loss (adjusted hazard ratio, 9.97; 95% CI, 4.90-20.3; P < 0.001). Risk factors included younger age, lower weight, higher Pediatric End-Stage Liver Disease score, longer cold ischemia and operation times, higher graft-to-recipient weight ratio, increased red blood cell transfusions, and biliary atresia. After adjusting for center, lower weight (odds ratio, 0.84 per kg; 95% CI, 0.71-1.00; P = 0.047) and biliary atresia (odds ratio, 2.34; 95% CI, 1.10-5.00; P = 0.027) remained predictors. Five-year patient (88.4% versus 93.1%) and graft survival (82.7% versus 96.3%) were significantly inferior in patients with PVT. Conclusions. Low-weight children with biliary atresia constituted a high-risk group, highlighting the necessity for early detection and management.

Abstract Patient preferences for communication of breast imaging results are heterogeneous and depend on the clinical context and perceived severity of findings. The 21st Century Cures Act, which mandates immediate electronic release of most medical records, has fundamentally altered result reporting and patient communication in breast imaging. Although this policy enhances transparency and timely access to information, it may conflict with established preferences for how patients receive screening mammography results, diagnostic evaluations, breast biopsy results, and breast cancer risk assessment information. Prior studies—largely conducted before widespread patient portal use—demonstrated that breast imaging patients consistently prioritize timely communication, while preferred delivery methods vary based on result acuity and emotional impact. However, much of this literature pre-dates implementation of the 21st Century Cures Act and widespread use of patient portals. This review examines the current literature to summarize evidence-based patient preferences for breast imaging result communication. As adoption of immediate result release continues to evolve across institutions, understanding contemporary patient preferences is essential to guiding radiologists in optimizing patient-centered communication strategies to inform best practices in breast imaging.
