Abstract
PURPOSE To evaluate duplex US findings of the HA in all three postoperative vascular (HA, PV, HV and IVC) complications of paediatric LT for early detection and some helpful secondary signs to determine these vascular complications. MATERIALS AND METHODS We collected data from 44 post-LT paediatric patients who underwent daily duplex US for seven consecutive days and three months after LT during January 2017-June 2020. Four duplex US parameters of the HA (extrahepatic PSV, intrahepatic PSV, RI and AT) were compared in patients with and without complications. RESULTS The PSV of the extrahepatic HA in patients with HA complications was higher than that in patients without complications (P value = 0.019). The PSV at 107.7 cm/s is the optimal cut-off parameter associated with HA complications [a sensitivity of 88.9% and a specificity of 80.0% (ROC area is 0.84)]. The intrahepatic RI was higher on the first day than on the last day and gradually decreased in patients without vascular complications (P value = 0.000). The intrahepatic PSV significantly decreased with time when comparing the first and last days in patients without PV and HV-IVC complications (P value = 0.014 and 0.038). In contrast, patients with vascular complications showed no significant decrease. CONCLUSION The extrahepatic PSV relates to HA complications after paediatric LT but not PV and HV-IVC complications. Non-significantly decreased intrahepatic RI and PSV from the first day to the day of complication diagnosis may correlate with the occurrence of vascular complications.

Abstract
PURPOSE Cholangiocarcinoma (CCA) is the second most common primary malignant hepatic tumor originating from bile duct epithelia. Bone metastasis is uncommon and less documented. The aim of this study was to characterize the imaging features of bone metastasis from CCA. METHODS A retrospective descriptive imaging characteristics in 199 patients (1465 lesions) diagnosed as CCA with bone metastasis were evaluated based on plain radiography, computed tomography (CT), magnetic resonance imaging (MRI) and Tc-99 m methylene diphosphonate bone scan. RESULTS The common vertebral metastatic sites were lumbar spines (94 [47.2 %], 95 %CI 40.1-54.4), upper thoracic spines (89 patients [44.7 %], 95 % CI 37.7-51.9), and lower thoracic spines (80 [40.2 %], 95 % CI 33.3-47.4). On plain radiograph, most of lesions had osteolytic pattern (68 %) with pedicular destruction (45.3 %) whereas on CT had mixed osteolytic and osteosclerotic destruction (40.8 %). The common non-vertebral metastatic sites were ribs and pelvis (80 patients [40.2 %], 95 % CI 33.3-47.4 and 60 [30.2 %], 95 % CI 23.9-37). On plain radiograph, in the long bones, usually had permeative destruction (58.9 %), whereas on CT showed mixed osteolytic and osteosclerotic (34.6 %). On bone scan, increased-uptake was the common pattern, found in the vertebral and non-vertebral sites (93.6 % and 92.4 %). CONCLUSIONS Bone metastasis from CCA usually occurred in the axial skeleton. The common patterns of destruction were osteolytic or mixed osteolytic and osteosclerotic. Periosteal reaction was scant in the appendicular long bones. On bone scan commonly had increased-uptake.
