RESUMO
BACKGROUND: To introduce a transjugular retrograde approach for AngioJet rheolytic thrombectomy (RT) just after transjugular placement of inferior vena cava filter (IVCF) to treat acute deep vein thrombosis (DVT). METHODS: From September 2018 to April 2019, transjugular Angiojet RT using pulse spray method was performed just after transjugular placement of IVCF in five patients (M:F = 3:2, mean age 70 years). Patients less than 165 cm in height with acute (<14 days) iliofemoral DVT were unable to assume a prone position. All patients underwent pre- and postprocedural venography to estimate thrombus reduction grade. Computed tomography angiograms at 3 and 6 months postoperative were compared with baseline scans. Post-thrombotic syndrome (PTS) symptoms were evaluated according to Villalta score during 12-month follow-up. RESULTS: Mean procedure time for all procedures was 1.4 h. Thrombus was completely reduced in three patients and 50% to 99% reduction was noted in the other two. No patients had major complications during the hospital stay and follow-up period. Distal migration of IVCF occurred in one patient during the procedure and immediate IVCF repositioning was performed. No DVT remained in follow-up computed tomography scans of all patients. PTS did not develop in any patients during the follow-up period. CONCLUSION: In patients who are unable to assume a prone position, a transjugular retrograde approach with AngioJet RT just after transjugular placement of IVCF to treat acute lower extremity DVT was a time-saving and easy alternative. During the procedure, attention to the guiding catheter position and AngioJet device movement was required to avoid affecting the IVCF.

PURPOSE: Lateral meniscus allograft transplantation (LMAT) is a feasible surgical option for young meniscus-deficient patients. Although several studies have explored the factors that contribute to graft extrusion, they have not been fully elucidated. The aim of this study was to determine the various factors that contribute to graft extrusion. METHODS: Patients with knees that had received LMAT using a keyhole technique (n = 87 knees in 82 patients) were reviewed. The median age of these patients was 22 years (range 19-54 years), and the median postprocedural follow-up interval was 5 days (range 1-136 days). Twelve magnetic resonance imaging (MRI) measurement parameters (axial and coronal location of the bone block) that could potentially influence graft extrusion were evaluated, along with absolute graft extrusion and relative percentage of extrusion (RPE). RESULTS: A significant correlation was found between 8 of the 12 MRI measurement parameters and both the absolute extrusion and RPE (r = 0.241-0.438, p < 0.05). The absolute middle distance and depth of the bone block were independent predictors of the absolute extrusion (ß = 0.30 and 0.15, respectively; p < 0.05), and the relative middle distance and relative bone-block elevation were found to be predictors of RPE (ß = 2.29 and 1.44, respectively; p < 0.05). CONCLUSION: The rate of graft extrusions after LMAT was high in this study. Both the coronal and axial locations of the bone block were found to influence graft extrusion in LMAT. Therefore, correct positioning of the bone block, including in both the axial and coronal planes, is essential to minimize graft extrusion. Future studies need to investigate the long-term clinical outcome and longevity of extruded menisci after transplantation. LEVEL OF EVIDENCE: Therapeutic case series, Level IV.

OBJECTIVE: To investigate the outcomes of percutaneous unilateral metallic stent placement in patients with a malignant obstruction of the biliary hila and a contralateral portal vein steno-occlusion. MATERIALS AND METHODS: Sixty patients with a malignant hilar obstruction and unilobar portal vein steno-occlusion caused by tumor invasion or preoperative portal vein embolization were enrolled in this retrospective study from October 2010 to October 2013. All patients were treated with percutaneous placement of a biliary metallic stent, including expanded polytetrafluoroethylene (ePTFE)-covered stents in 27 patients and uncovered stents in 33 patients. RESULTS: A total of 70 stents were successfully placed in 60 patients. Procedural-related minor complications, including self-limiting hemobilia (n = 2) and cholangitis (n = 4) occurred in six (10%) patients. Acute cholecystitis occurred in two patients. Successful internal drainage was achieved in 54 (90%) of the 60 patients. According to a Kaplan-Meier analysis, median survival time was 210 days (95% confidence interval [CI], 135-284 days), and median stent patency time was 133 days (95% CI, 94-171 days). No significant difference in stent patency was observed between covered and uncovered stents (p = 0.646). Stent dysfunction occurred in 16 (29.6%) of 54 patients after a mean of 159 days (range, 65-321 days). CONCLUSION: Unilateral placement of ePTFE-covered and uncovered stents in the hepatic lobe with a patent portal vein is a safe and effective method for palliative treatment of patients with a contralateral portal vein steno-occlusion caused by an advanced hilar malignancy or portal vein embolization. No significant difference in stent patency was detected between covered and uncovered metallic stents.

PURPOSE: The objective of this study was to evaluate the course of clinical stability in patients with acute eosinophilic pneumonia (AEP) who did not receive corticosteroid treatment. METHODS: Secondary analysis included 19 consecutive patients with AEP who did not receive corticosteroid treatment from a cohort of 310 patients newly diagnosed with AEP between October 2007 and December 2013. RESULTS: All patients presented with dyspnea, fever, or cough with diffuse pulmonary infiltration. All but one patient (95 %) had elevated C-reactive protein (CRP), and 11 (58 %) patients had peripheral eosinophilia at the time of diagnosis. During the follow-up period, the dyspnea improved within a median of 4 (3-6) days and defervescence occurred within a median of 5 (4-7) days. Median time to clinical stability (defined as disappearance of all initial presenting symptoms) was 9 (7-12) days. In addition, the majority of pulmonary infiltrates on chest radiographs completely disappeared within 14 days after diagnosis. However, the peripheral eosinophil count and the frequency of peripheral eosinophilia increased up to 10 days and then decreased during the follow-up period. All patients experienced peripheral eosinophilia during hospitalisation. CONCLUSION: AEP-associated symptoms and radiographic abnormalities were resolved completely within 2 weeks after diagnosis even when corticosteroid treatment was not initiated. However, these findings might be limited to relatively mild cases of AEP.

Hepatic involvement of amyloidosis is common. Diffuse infiltration with hepatomegaly is a usual radiologic finding of hepatic amyloidosis. To our knowledge, this is the first case of amyloidosis involving the liver that presented as a mass.
