RF ablation has the following advantages in the treatment of hepatic hemangiomas: minimal invasiveness, definite efficacy, high safety, fast recovery, relatively simple operation, and wide applicability. It is necessary to formulate a widely accepted consensus among the experts in China who have extensive expertise and experience in the treatment of hepatic hemangiomas using RF ablation, which is important to standardize the application of RF ablation for the management of hepatic hemangiomas, regarding the selection of patients with suitable indications to receive RF ablation treatment, the technical details of the techniques, therapeutic effect evaluations, management of complications, etc. A final consensus by a Chinese panel of experts who have the expertise of using RF ablation to treat hepatic hemangiomas was reached by means of literature review, comprehensive discussion, and draft approval.展开更多

When the anatomical positions were not ideal, the diagnosis was difficult by SPECT only. So the information of computed tomography (CT) was applied to help in diagnosing. The results were recorded as hemangiomas or not.RESULTS: Of the 54 patients, 31 patients were diagnosed as suffering from hepatic hemangiomas. The anatomical positions of eight patients' hepatic hemangiomas (25.81%)were not ideal. Among these lesions of the eight patients,three patients' hepatic lesions were located near to the abdominal aorta, one to the heart, and four to the inferior cava. In addition, six abnormal radioactivity accumulation regions, adjacent to the heart and inferior cava, with the help of CT, were confirmed to be the imaging of inferior cava other than hepatic hemangiomas.CONCLUSION: When the anatomical positions of hepatic hemangiomas are not good enough for diagnosis, the fusion imaging of SPECT/CT is a simple and efficient method for differential diagnosis.展开更多

Methods： From May 1994 to September 2006, fortythree patients underwent the surgical removal of the cavernous hepatic hemangioma were analyzed retrospectJvely. Enucleation was used for 16 cases and hepatectomy for 27 cases. The relative clinical data and operative factors between the two operative techniques were compared. Results： Statistically significant differences in tumor size, location and intraoperative blood lose between the two groups were observed （P 〈 0.05 ）. Although enucleation was associated with less intraoperative bleeding and transfusion requirement but no significant differences in postoperative liver functional parameter, complication and length of hospital stay were observed. Conclusion： With proper choice, enucleation and hepatectomy both are effective treatments for cavernous hepatic hemangiomas.展开更多

METHODS: The clinical data from 28 patients, who underwent hepatic resection requiring intraoperative autologous transfusion with the cell-saver apparatus, were analyzed retrospectively. The tumors in the 28 patients involved the proximal hepatic veins and inferior vena cava. The diameters of these hemangiomas ranged from 12x15 cm to 18-40 cm. All patients had varying degrees of THVE. ' RESULTS: The 28 patients with hemangioma received integrated resection and recovered. One patient had rupture of tumors resulting in massive hemorrhage of 6000 ml during liver resection; 4 patients had blood transfusions of 400-800 ml; the other 23 patients had no blood transfusion. Only 6 patients underwent the Pringle maneuver with resection. The other 22 patients underwent THVE during the liver resection. The interval of THVE was 5-30 minutes (mean 16 minutes). CONCLUSIONS: Intraoperative autologous transfusion during modified, normal-temperature THVE for extracapsular resection of huge hepatic cavernous hemangioma is feasible.展开更多

The patient had a history of a giant hepatic cavernous hemangioma. Emergency exploratory laparotomy was performed for suspected intra-abdominal bleeding with abdominal compartment syndrome, and more than 4 liters of blood and blood clots were removed. An active bleeding laceration （5 cm） of a hepatic cavernous hemangioma was detected in segment III of the liver. The bleeding was controlled by sutures, Teflon patches and tamponade. The abdomen was closed temporarily using the vacuum-assisted method. Because of the presence of persistent fresh blood through abdominal drainage at a rate of 〉1 L/h, splenectomy was performed to control the bleeding again by sutures and Teflon patches. Finally, the abdomen was closed using a biologic mesh. The patient was discharged home 30 days after trauma. Bleeding of trauma-caused hepatic hemangioma is rare, but splenic injury due to blunt abdominal trauma is common. An in-depth investigation is necessary to avoid second intervention.展开更多

Bleeding of trauma-caused hepatic hemangioma is rare, but splenic injury due to blunt abdominal trauma is common. An in-depth investigation is necessary to avoid second intervention.
文摘Differential diagnosis of pediatric vascular liver tumors can be challenging due to inconsistent nomenclature,histologic overlap and the rarity of some entities.Here we give an up-to-date overview of the most important entities.We discuss the clinic,histology and pathophysiology of hepatic congenital and infantile heman-gioma,hepatic epithelioid hemangioendothelioma and hepatic angio-sarcoma.
文摘Benign liver tumors are common lesions that are usually asymptomatic and are often found incidentally due to recent advances in imaging techniques and their widespread use.Although most of these tumors can be managed conservatively or treated by surgical resection,liver transplantation(LT)is the only treatment option in selected patients.LT is usually indicated in patients that present with life-threatening complications,when the lesions are diffuse in the hepatic parenchyma or when malignant transformation cannot be ruled out.However,due to the significant postoperative morbidity of the procedure,scarcity of available donor liver grafts,and the benign course of the disease,the indications for LT are still not standardized.Hepatic adenoma and adenomatosis,hepatic hemangioma,and hepatic epithelioid hemangioendothelioma are among the most common benign liver tumors treated by LT.This article reviews the role of LT in patients with benign liver tumors.The indications for LT and long-term outcomes of LT are presented.

文摘Background and Aims:Hepatocellular carcinoma(HCC)is the most common primary hepatic malignancy.This study was designed to investigate the value of computed tomography(CT)spectral imaging in differentiating HCC from hepatic hemangioma(HH)and focal nodular hyperplasia(FNH).Methods:This was a retrospective study of 51 patients who underwent spectral multiple-phase CT at 40–140 keV during the arterial phase(AP)and portal venous phase(PP).Slopes of the spectral curves,iodine density,water density derived from iodine-and water-based material decomposition images,iodine uptake ratio(IUR),normalized iodine concentration,and the ratio of iodine concentration in liver lesions between AP and PP were measured or calculated.Results:As energy level decreased,the CT values of HCC(n=31),HH(n=17),and FNH(n=7)increased in both AP and PP.There were significant differences in IUR in the AP,IUR in the PP,normalized iodine concentration in the AP,slope in the AP,and slope in the PP among HCC,HH,and FNH.The CT values in AP,IUR in the AP and PP,normalized iodine concentration in the AP,slope in the AP and PP had high sensitivity and specificity in differentiating HH and HCC from FNH.Quantitative CT spectral data had higher sensitivity and specificity than conventional qualitative CT image analysis during the combined phases.Conclusions:Mean CT values at low energy(40–90 keV)and quantitative analysis of CT spectral data(IUR in the AP)could be helpful in the differentiation of HCC,HH,and FNH.

文摘Background:Infantile hepatic hemangioma(IHH)as a benign liver tumor in infancy and childhood is commonly associated with high output cardiac failure.The present study aims to describe the imaging findings in a patient who was diagnosed as having multiple IHH with congestive cardiac insuffi ciency.Methods:The imaging findings and clinical manifestations of the patient with multiple IHH associated with cardiac insuffi ciency were retrospectively reviewed.Results:Ultrasonography showed multiple intrahepatic lesions with mixed echoes and markedly expanded hepatic veins and the inferior vena cava of the patient.Echocardiography revealed right heart insufficiency and pulmonary hypertension.Contrast-enhanced MRI showed early mild enhancement of lesions and more obvious delayed enhancement.The patient died after combined therapy of surgery and hormone.Conclusions:The imaging findings of multiple IHH associated with cardiac insufficiency are typical and diagnostic.Early imaging assessment may facilitate the diagnosis and treatment of the disease.
