ABSTRACT
Objective To assess the safety and effectiveness of yttrium-90 (90Y) radioembolization for patients with hepatocellular carcinoma (HCC) and portal vein tumor thrombosis (PVTT).Methods The PubMed was searched for all clinical reports from 1991 to 2017.Results A total of 17 clinical studies including 662 patients were qualified for the analysis.The median time to progression was 5.8 months,and median disease control rate was 68.4％.The median survival was 10 months in all patients,including the median OS of 13.8,6.5 months of Child-Pugh class A and B patients,respectively,the median OS were 13.4,5.4 months respectively in branch and main PVTT patients,and the median OS were 3.7,9.5 months of patients who received resin and glass based microspheres,respectively.The median radioembolization induced liver disease was 36.3％.The median abdominal pain,nausea/vomiting,fatigue,and fever were 18.8％,17.6％,11.1％,and 1.4％.Conclusion 90y radioembolization is an effective treatment for HCC and PVTT,which is an alternative treatment choice for HCC and PVTT.
ABSTRACT
Objective To investigate the CT and MRI manifestations of intra-abdominal aggressive fibromatosis and correlation with pathology.Methods The CT and MRI manifestations of 26 cases with intra-abdominal aggressive fibromatosis confirmed by pathological examination were analyzed retrospectively.Results 26 cases showed single solid mass,13 cases showed well-circumscribed and round-like,9 cases wrapped around the common bile duct,intestine or ureter,4 cases were lobulated which had unclear margin with surrounding tissues in pelvic.All the lesions displayed isodensity or slightly low density non-enhanced CT appearance,heterogenous high intensity FS T2WI,some larger tumors showed mixed signal.CT/MRI enhanced scan showed gradual enhancement in 26 cases.Conclusion Intra-abdominal aggressive fibromatosis have some certain imaging features,MRI can offer the histo logical features of tumors and have some correlation with pathology.
ABSTRACT
Objective@#To evaluate the correlation between bile duct injury after transcatheter arterial chemoembolization and the level of hepatic arterial embolization, and to analyze the clinical prognosis of hepatocellular carcinoma patients.@*Methods@#From January18, 2012 to December18, 2014, 21 patients underwent TACE for HCC were retrospectively reviewed, including patients′ clinical and pathological data. The clinical outcome and relevant factors for bile duct injury were analyzed.@*Results@#A total of 21 patients were identified with bile duct injury at our single institution. All patients received 48 TACE treatments, including proper hepatic artery (14), left hepatic artery (3), the right hepatic artery (10), left and right hepatic artery (9) and tumor artery branches (12). Thirty-five bile duct injury occurred in 21 patients: 7 cases was close to the tumor, 2 distant to the tumor, 7 at right liver, 2 left liver, 11 both lobes of liver and 6 hepatic hilar. After medical conservative treatment and biliary tract inside and outside drainage, liver function of 10 cases were improved. In four patients with hepatic bile duct stricture and biloma, the effect of drainage was not obvious, which subsequently caused biliary complications such as infection, gallbladder and common bile duct stones. Three patients with liver cirrhosis at decompensation stage developed complications, and one of them died of hepatic encephalopathy. Four patients experienced tumor recurrence during the follow-up period.@*Conclusions@#The location of bile duct injury after transcatheter arterial chemoembolization is quite consistent with the level of hepatic arterial embolization. There may be some blood vessels mainly involved in blood supply of biliary duct. Complete embolism of these vessels may lead to bile duct injuries. Biliary drainage is ineffective in patients with hilar bile duct stricture, and can lead to complications of biliary tract later on.
ABSTRACT
Transcatheter arterial chemoembolization (TACE) has been widely applied in palliative treatment of unresectable primary and metastatic liver cancer,and its efficiency and safety also have been widely acknowledged.However,there is a wide range of related complications,such as upper gastrointestinal hemorrhage,liver failure,pulmonary embolism,embolic cholecystitis and so on.As a serious complication of TACE,bile duct injury has been reported intermittently since the introduction of hepatic arterial embolization therapy.However,the exact pathogenesis,predisposing factors and clinical implications of the injuries remain to be clarified.As we find,by far there is no literature review about the bile duct injury after TACE for liver malignant tumors both at home and abroad.Thus the purpose of our study was to discuss such current issue of bile duct injury,and 26 articles have been included and analyzed.
