RESUMO

Intravenous leiomyomatosis is a rare type of tumor that is histologically benign but biologically invasive. It originates from the smooth muscle of the uterine or the uterine vein. It can grow through the uterus and extend into the pelvic cavity, or grow along the veins without invading the wall of the venous vessel itself. The tumors are estrogen-dependent and can metastasize through the bloodstream. Thus, in addition to continuous growth, some tumors exhibit isolated growths in the venous system and heart chambers or show disseminated growth in the lungs, although distant metastasis to other regions usually do not occur. Currently, there is limited research on this disease, the majority of which are case reports, surgical experience summaries, and differentiation from ordinary gynecological myomas in terms of pathogenesis and radiological diagnostic experience. There are two main theories on the origin of the disease: uterine smooth muscle and smooth muscle of the uterine veins. Some studies have verified the role of estrogen, progesterone receptor-related pathways, and angiogenesis in the development of the disease. The clinical symptoms of this disease are varied, depending on the affected area. In the early stages, when the tumor only affects the pelvic cavity, patients show mild symptoms resulting from pelvic organ compression. When it progresses to the inferior vena cava and heart, patients show more complex symptoms resulting from venous return obstruction, cardiac obstruction, and hemodynamics appearing. Different institutions have proposed different disease staging and classification strategies for different clinical purposes. Some are based on the affected area of the lesion; others are based on the size of the tumor. Although surgery remains the main treatment for this disease, the specific surgical approach, adjuvant drug therapy, and prognosis still need further exploration.

RESUMO

Objective: To analyze the clinical and prognosis of children with kidney retransplantation. Methods: Clinical data of 11 children who underwent kidney retransplantation from January 2011 to December 2020 in Department of Nephrology, Children's Hospital of Fudan University were retrospectilely analyzed. The clinical data including demographic parameters, primary diagnosis, characteristics in the follow-up of renal allograft were analyzed. Results: Totally 11 cases received secondary renal transplantation (male 6, female 5). They were initially diagnosed with chronic kidney disease at the age of 11.9 (7.4, 13.3) years. The median duration of dialysis was 22.1 (3.5, 36.5) months. In the first transplantation, recipient age was 13.9 (11.1, 15.2) years. Ten cases received donation from cardiac death donor (DCD) (9 cases received donors aged less than one year, 5 of them received whole kidney transplantation and one case received donor aged one to three years) and 1 case with living-related donor. Ten graft failures occurred within 1 month after renal transplantation and the other one occurred at the fifth month after transplantation. The causes included vascular factors (9 cases), rejection (1 case) and primary non-function (1 case). In the second transplantation, recipient age was 14.7 (11.7, 16.2) years. All the 11 children received dialysis (7 with PD and 4 with HD) and successfully completed the second transplantation. The median time between the two transplants was 210 (16, 1 041) days. Donors were all DCD donors from 3 years of age or older. The mean follow-up duration was (42±15) months. The estimated glomerular filtration rate was (85±34)ml/(min·1.73 m2) when the last investigation after kidney retransplantation with the kidney and patient all survived. Conclusions: Kidney retransplantation may have better prognosis in children. Dialysis transition during waiting period and DCD donor from 3 years of age or older can effectively ensure the success of kidney retransplantation.

RESUMO

BACKGROUND: Adenosquamous carcinoma (ASC) of the lung is a heterogeneous disease that is composed of both adenocarcinoma components (ACC) and squamous cell carcinoma components (SCCC). Their genomic profile, genetic origin, and clinical management remain controversial. PATIENTS AND METHODS: Resected ASC and metastatic tumor in regional lymph nodes (LNs) were collected. The ACC and SCCC were separated by microdissection of primary tumor. The 1021 cancer-related genes were evaluated by next-generation sequencing independently in ACC and SCCC and LNs. Shared and private alterations in the two components were investigated. In addition, genomic profiles of independent cohorts of adenocarcinomas and squamous cell carcinomas were examined for comparison. We have also carried out a retrospective study of ASCs with known EGFR mutation status from 11 hospitals in China for their clinical outcomes. RESULTS: The most frequent alterations in 28 surgically resected ASCs include EGFR (79%), TP53 (68%), MAP3K1 (14%) mutations, EGFR amplifications (32%), and MDM2 amplifications (18%). Twenty-seven patients (96%) had shared variations between ACC and SCCC, and pure SCCC metastases were not found in metastatic LNs among these patients. Only one patient with geographically separated ACC and SCCC had no shared mutations. Inter-component heterogeneity was a common genetic event of ACC and SCCC. The genomic profile of ASC was similar to that of 170 adenocarcinomas, but different from that of 62 squamous cell carcinomas. The incidence of EGFR mutations in the retrospective analysis of 517 ASCs was 51.8%. Among the 129 EGFR-positive patients who received EGFR-TKIs, the objective response rate was 56.6% and the median progression-free survival was 10.1 months (95% confidence interval: 9.0-11.2). CONCLUSIONS: The ACC and SCCC share a monoclonal origin, a majority with genetically inter-component heterogeneity. ASC may represent a subtype of adenocarcinoma with EGFR mutation being the most common genomic anomaly and sharing similar efficacy to EGFR TKI.

RESUMO

Objective: To analyze the clinical, radiologic characteristics, and outcome of consecutive patients with primary cardiac angiosarcoma. Methods: The medical records of patients with primary cardiac angiosarcoma diagnosed through pathology at Peking Union Medical College Hospital between January 2001 and May 2018 were obtained. The results of echocardiography, coronary artery CT angiography (CTA), cardiac magnetic resonance (CMR), positron emission computed tomography (PET-CT), operation, postoperative treatment and prognosis of the patients were analyzed. Results: A total of 16 patients were included, 9 were male, 7 were female, the median age was 42.5 years (31.7, 52.5). The interval from symptoms onset to diagnosis was 4.5 months (0.5-18.0 months). Eight patients were diagnosed at non-metastatic phase, while 8 patients were in metastatic phase. The main complaints were dyspnea, short breath, chest pain, hemoptysis, syncope, edema, fever, fatigue, and cough. Three patients (18.8%) had pericardial tamponade in the course of the disease. Echocardiography was performed on all 16 patients, cardiac mass was found in 12 patients, and pericardial effusion or pericardial thickening was observed in 4 patients. In 8 cases with results of coronary CTA, 5 cases presented signs of right atrium occupation, 1 case presented sign of right ventricle occupation, and 1 case presented isolated massive pericardial effusion. None abnormality was found in 1 case. Of the 7 patients who underwent CMR, 6 presented with right atrium mass occupation and 1 mediastinal mass. Four patients received PET-CT examination and results showed that all presented with hypermetabolic lesions: 2 in right atrium, 1 in pericardium, and 1 in mediastinum, and lung metastasis was found in 2 cases. Among the 16 patients, 13 received surgical treatment, 2 received adjuvant chemotherapy, and 1 received chemotherapy and radiotherapy after biopsy. The median overall survival was 3.0 months. Conclusion: Cardiac angiosarcoma is a rare malignancy with poor prognosis, and echocardiography has only limited diagnostic value for angiosarcoma. CMR, CTA or PET-CT examinations could provide valuable clues for the diagnosis of this rare disease.

RESUMO

Objective: The study was designed to analyze the clinicopanthologic characteristics, treatments and outcomes of a series of patients with primary angiosarcoma. Methods: The clinical, surgical and pathological data and treatment of 68 patients with pathologically confirmed angiosarcoma admitted to Peking Union Medical College Hospital from January 1990 to June 2017 was retrospectively analyzed. Kaplan-Meier method and Log rank test were used for univariate survival analysis and Cox regression model was used for multivariate survival analysis. Results: A total of 68 patients were enrolled, 38 were male, 30 were female. The median age at diagnosis was 50.5 years. The time from symptom onset to diagnosis was (7.5±7.5) months. The primary sites included face and scalp, breast, chest wall, lung, heart, liver, spleen, extremities, bones and so on. At diagnosis, the mean size of tumors were (7.4±7.3) cm, 28 patients (41.2%) had localized disease (stage Ⅰ+ Ⅱ) and 40 patients had metastatic disease (stage Ⅲ+ Ⅳ). There were 37 patients treated with surgery alone, three receiving radiotherapy alone, five receiving chemotherapy alone and sixteen receiving comprehensive treatment with 5 underwent surgery plus radiotherapy, three treated by surgery plus chemotherapy, four had surgery plus interventional therapy, two had chemoradiotherapy, one had radiotherapy and interventional therapy and 1 had surgery plus chemoradiotherapy and targeted therapy. Five patients received only palliative treatment, and 2 patients lost follow-up after diagnosed. Fifty patients were followed up with a median overall survival time of 8.5 months. The median survival time of patients with metastatic angiosarcoma was 6.6 months, significantly shorter than that of patients with localized disease (15.0 months, P=0.020). The median survival time of patients with cardiac angiosarcoma was 3.0 months, significantly shorter than that of patients with angiosarcoma at other sites (11.5 months, P=0.010). The median survival time of patients receiving comprehensive treatment was 31.0 months, significantly longer than that of patients without comprehensive treatment (5.6 months, P=0.007). Multivariate analysis showed that staging, heart occurrence and comprehensive treatment were independent factors for the prognosis of primary angiosarcoma (all P<0.05). Conclusions: Angiosarcoma is a rare malignancy, and patients with metastatic disease or cardiac occurence have poor prognosis. Comprehensive treatment can improve the prognosis of patients with angiosarcoma.

RESUMO

Objective: To explore the clinicopathological features of anti-mitochondrial antibody (AMA) negative and positive patients with primary biliary cholangitis-autoimmune hepatitis overlap syndrome (PBC-AIH OS). Methods: Seventy-four cases diagnosed as PBC-AIH OS from June 2017 to April 2018 were enrolled in this study. Among them, forty cases were AMA negative (negative group) and thirty-four cases were AMA positive (positive group). The clinical manifestations, serum biochemical indexes, immunological indexes and histological data of the negative group were compared with the positive group. Mann-Whitney U test and theχ (2)test were used for statistical analysis. Results: There was no significant difference in sex, age, clinical manifestations and major liver function indexes (ALT, AST, ALP, GGT, TB, DB) between the negative group and positive group (P> 0.05). The level of IgM in the negative group (1.68 ± 0.87) was significantly lower than positive group (3.77 ± 2.88)(P< 0.05). The positive rates of antinuclear antibodies (ANA) and gp-210 antibodies was lower than positive group (P< 0.05). There were no significant differences in the stages of inflammation and fibrosis between the two groups (P> 0.05), and the bile duct injury was more significant in the negative than positive group (P< 0.05). Conclusion: The serum IgM level of AMA-negative PBC-AIH OS is low, and immunological antibody is often negative, which makes bile duct injury apparent in liver histology. A liver biopsy should be carried out as soon as possible for early diagnosis and treatment.

RESUMO

Objective: To probe into the mechanism and interventional effects of silybin-phospholipid complex on amiodarone-induced steatosis in mice. Methods: Eight-week-old male C57BL/6 mice were divided into three groups (5 mice in each group): a control group (WT) with normal diet, a model group with amiodarone 150mg/kg/d by oral gavage (AM), and an intervention group on amiodarone 150mg/kg/d combined with silybin-phospholipid complex(AM+SILIPHOS. All mice were fed their assigned diet for one week. Then, one week later, serum alanine aminotransferase, aspartate aminotransferase, triglyceride, total cholesterol and high-density lipoprotein were detected of each group. A liver pathological change was observed by oil red O and H&E staining. Ultrastructural pathological changes of hepatocytes were observed to evaluate the intervention effect by transmission electron microscopy. RT-q PCR was used to detect the expression of peroxisome proliferator-activated receptor alpha and its regulated lipid metabolism genes CPTI, CPTII, Acot1, Acot2, ACOX, Cyp4a10 and Cyp4a14 in liver tissues. Intra-group comparison was done by paired t-test. One-way ANOVA was used for comparison between groups and semi-quantitative data were tested using Mann-Whitney U test. Results: Oil Red O and H&E staining results of liver tissue in the intervention group showed that intrahepatic steatosis was significantly reduced when compared to model group. Transmission electron microscopy showed that the model group had pyknotic nuclei, mitochondrial swelling, structural damage, and lysosomal degradation whereas the intervention group had hepatic nucleus without pyknosis, reduced mitochondrial swelling and slight structural damage than that of model group. RT-q PCR results showed that the expression of peroxisome proliferator-activated receptor alpha, CPTI, CPTII, Acot1, Acot2, ACOX, Cyp4a10 and Cyp4a14 were increased in the model group but the expression of CPTI, Cyp4a14, Acot1 and peroxisome proliferator-activated receptor alpha were decreased in the intervention group (P < 0.05). Conclusion: Silybin-phospholipid complex can alleviate amiodarone-induced steatosis, and its mechanism may play a role in protecting mitochondrial function and regulating fatty acid metabolism. Thus, silybin-phospholipid complex has potential intervention effect on amiodarone-induced fatty liver.

RESUMO

OBJECTIVE: Baculoviral inhibitor of apoptosis repeat-containing 5 (BIRC5) is a member of apoptosis inhibition family which suppresses caspase activity. Osteosarcoma tissues have significantly higher BIRC5 and lower microRNA-218 (miR-218) level than adjacent tissues, indicating tumor suppressor role of miR-218 in osteosarcoma. Bioinformatics analysis showed satisfactory targeting correlation between miR-218 and 3'-UTR of BIRC5 mRNA. This study, thus, investigated if dysregulation of miR-218 and BIRC5 affected apoptosis of osteosarcoma cells U2OS. PATIENTS AND METHODS: A total of 42 osteosarcoma patients were collected for tumor and adjacent tissues to compare miR-218 and BIRC5 expressions. Dual-luciferase reporter gene assay examined targeted regulation between miR-218 and BIRC5. In vitro cultured U2OS cells were treated with miR-218 mimic and/or si-BIRC5. Caspase-3 activity was measured by spectrometry while flow cytometry was used to test cell apoptosis, plus protein expression assay by Western blot assay. RESULTS: Compared to adjacent tissues, osteosarcoma tissues had significantly depressed miR-218 expression and elevated BIRC5 expression (p<0.05). miR-21 targeted 3'-UTR of BIRC5 to suppress its expression. The elevation of miR-218 and/or silencing BIRC5 significantly depressed BRIC5-induced inhibition on caspase-5, and facilitated U2OS cell apoptosis (p<0.05). CONCLUSIONS: We observed that miR-218 was significantly down-regulated in osteosarcoma tissues, which had elevated BIRC5 expression. MiR-218 targeted and inhibited BIRC5 expression, weakened caspase-5 inhibition by BIRC5, and facilitated U2OS osteosarcoma cell apoptosis.

RESUMO

AIMS: Guidelines recommend the discussion of adjuvant radiotherapy post-prostatectomy for prostate cancer patients with high-risk pathology to consider all of their treatment options. We determine whether patterns of radiotherapy referral and treatment post-prostatectomy reflect guideline-based use in a contemporary prostatectomy cohort. MATERIALS AND METHODS: Electronic treatment records were linked to Ontario's cancer registry. Multivariable regression was used to evaluate clinical and health systems factors associated with referral and the use of adjuvant radiotherapy within 6 months post-prostatectomy. RESULTS: Among 2663 patients treated with prostatectomy between 1 January 2012 and 30 November 2012, 1261 (47%) were found to have adverse pathology and 492 were referred to radiation oncology ≤6 months post-prostatectomy, of whom 51% received adjuvant radiotherapy. Multivariable analysis showed that patients were more likely to be referred to radiation oncology from a low-volume surgical facility (≤50 versus >50 radical prostatectomy cases, odds ratio 2.50 [1.80-3.48]), if they lived farther from a radiotherapy centre (>50 km versus <10 km, odds ratio 1.73 [1.22-2.46]), if they were seen by radiation oncology preoperatively (odds ratio 1.95 [1.51-2.52]), or if they had adverse pathology: high T-category (pT3b/T4 versus pT2, odds ratio 17.87 [12.14-26.30]; pT3a versus pT2, odds ratio 5.24 [3.95-6.97]), positive margins (non-apex positive versus negative, odds ratio 4.20 [3.19-5.53]; apex only positive versus negative, odds ratio 2.60 [1.71-3.94]) and high Gleason score (8-10 versus ≤6, odds ratio 11.32 [5.37-23.84]; 7 versus ≤6, odds ratio 4.18 [2.16-8.10]). Wide geographic variation in radiotherapy referral rates persisted (range 6-66%; P < 0.0001). After radiotherapy referral, only high T-category (pT3b/T4 versus pT2, odds ratio 5.37 [3.01-9.60]; pT3a versus pT2, odds ratio 2.72 [1.59-4.65]) and non-apex positive margins (odds ratio 2.81 [1.86-4.23]) remained significantly predictive of treatment. CONCLUSIONS: Variations in referral for a discussion of radiotherapy post-prostatectomy are not mainly explained by patient characteristics. After seeing radiation oncology, treatment decisions correlated most strongly with pathological findings. Understanding the reasons for the tremendous non-clinical variations in care is needed to ensure access to potentially curative radiotherapy post-prostatectomy for high-risk prostate cancer patients.

RESUMO

BACKGROUND: Although high-dose interferon (hd-ifn) is the sole approved adjuvant systemic treatment for melanoma in many jurisdictions, it is toxic. We sought to assess the population-level effects of hd-ifn toxicity, particularly neuropsychiatric toxicity, hypothesizing that such toxicity would have the greatest effect on mental health services use in advanced resected melanoma. METHODS: This retrospective population-based registry study considered all melanoma patients receiving adjuvant hd-ifn in Ontario during 2008-2012. Toxicity was investigated through health services use compatible with hd-ifn toxicity (for example, mental health physician billings). Using stage data reported from cancer centres about a subset of patients (stages iib-iiic), a propensity-matched analysis compared such service use in patients who did and did not receive hd-ifn. Associations between early hd-ifn discontinuation and health services use were examined. RESULTS: Of 718 melanoma patients who received hd-ifn, 12% were 65 years of age and older, and 83% had few or no comorbidities. One third of the patients experienced 1 or more toxicity-associated health care utilization events within 1 year of starting hd-ifn. Of 420 utilization events, 364 (87%) were mental health-related, with 54% being family practitioner visits, and 39% being psychiatrist visits. In the propensity-matched analysis, patients receiving hd-ifn were more likely than untreated matched controls to use a mental health service (p = 0.01), with 42% of the control group and 51% of the hd-ifn group using a mental health service in the period spanning the 12 months before to the 24 months after diagnosis. In the multivariable analysis, early drug discontinuation was more likely in the presence of pre-existing mental health issues (odds ratio: 2.0; 95% confidence limits: 1.1, 3.4). CONCLUSIONS: Stage iib-iiic melanoma patients carry a substantial burden of mental health services use whether or not receiving hd-ifn, highlighting an important survivorship issue for these patients. High-dose interferon is associated with more use of mental health services, and pre-treatment use of mental health services is associated with treatment discontinuation. That association should be kept in mind when hd-ifn is being considered.

RESUMO

The localization of prenylated Ras at the plasma membrane promotes activation of Ras by receptor tyrosine kinases and stimulates oncogenic signaling by mutant Ras. The Nogo-B receptor (NgBR) is a transmembrane receptor that contains a conserved hydrophobic pocket. Here, we demonstrate that the NgBR promotes the membrane accumulation of Ras by directly binding prenylated Ras at the plasma membrane. We show that NgBR knockdown diminishes the membrane localization of Ras in multiple cell types. NgBR overexpression in NIH-3T3 fibroblasts increases membrane-associated Ras, induces the transformed phenotype in vitro, and promotes the formation of fibrosarcoma in nude mice. NgBR knockdown in human breast cancer cells reduces Ras membrane localization, inhibits epidermal growth factor (EGF)-stimulated Ras signaling and diminishes tumorigenesis of xenografts in nude mice. Our data demonstrate that NgBR is a unique receptor that promotes accumulation of prenylated Ras at the plasma membrane and promotes EGF pathways.

RESUMO

OBJECTIVE: To identify risk factors of neurological complications (NC) in left-sided infective endocarditis (IE) and to assess its impact on the outcome and cardiac surgery. METHODS: Clinical data, NC, treatment and outcome of patients with definite left-sided IE admitted to our hospital during 2001-2012 were retrospectively analyzed. RESULTS: A total of 308 patients with age of (45.3±15.9) years were enrolled. Among them, 65 (21.1%) experienced at least one NC. Independent risk factors associated with NC were large vegetation (HR=1.681, 95%CI 1.013-2.788, P=0.044), non-neurologic embolism (HR=1.820, 95%CI 1.068-3.100, P=0.028), mitral valve involvement (HR=1.888, 95%CI 1.089-3.274, P=0.024), Staphylococcus aureus infection (HR=2.054, 95%CI 1.097-3.846, P=0.044), and uncontrolled infection (HR=4.680, 95%CI 2.563-8.546, P<0.001). During a median follow-up for 17 months, 70 (22.7%) patients died. NC had a negative impact on long-term outcome (HR=2.292, 95%CI 1.274-4.122, P=0.006). Valve replacement surgery was performed in 156(50.6%)patients, which was associated with a lower rate of 1-year IE-related death (HR=0.160, 95%CI 0.063-0.405, P<0.001). Among patients with NC, valve replacement surgery was associated with lower rates of in-hospital mortality and 1-year IE-related mortality (14.8% vs 5.3%, 18.5% vs 73.7%, respectively, P<0.001). CONCLUSIONS: Independent risk factors of NC include large vegetation, non-neurologic embolism, mitral valve involvement, Staphylococcus aureus infection, and uncontrolled infection. Neurologic complications link to the poor prognosis in patients with left-sided IE. Valve surgery is considered as a safe procedure and improves the survival.

RESUMO

AIMS: Adjuvant radiotherapy post-prostatectomy has been shown to benefit patients with adverse pathology. It remains unclear whether salvage radiotherapy confers equivalent outcomes. Practice guidelines recommend referral to radiation oncology within 6 months after prostatectomy to discuss adjuvant and salvage radiotherapy. The study objectives were to assess, at a population level: (i) post-prostatectomy referral patterns for radiotherapy; (ii) adjuvant and salvage radiotherapy utilisation; and (iii) time trends in relation to clinical trials and guidelines. These findings provide indications of access to quality care. MATERIALS AND METHODS: This was a retrospective cohort study. Electronic radiotherapy consultation and treatment records were linked to the population-based Ontario Cancer Registry. The population included prostate cancer cases treated with prostatectomy in Ontario between 2003 and 2012. Radiotherapy referral and treatment rates over time were analysed using the chi-squared trend test. RESULTS: Over the study period, 30 447 prostate cancer patients received prostatectomy. The proportion seen by radiation oncology within 6 months after prostatectomy doubled from 10.7% in 2003-2004 to 21.7% in 2011-2012 (P < 0.0001 for trend), with the largest annual percentage difference in 2009-2011 (3.4%). Among 4641 patients seen within 6 months, adjuvant radiotherapy rates remained at 51.0% ± 3.0%. Contemporaneous with radiation oncology referral trends, overall adjuvant radiotherapy use increased from 6.2% in 2003-2004 to 11.0% in 2011-2012 (P < 0.001), while salvage radiotherapy remained at 8.4% ± 0.4%. Consequently, the total proportion receiving radiotherapy within 24 months increased from 14.1% in 2003-2004 to 17.7% in 2009-2010 (P < 0.0001). CONCLUSIONS: There was an increase in access to early radiation oncology referral post-prostatectomy and adjuvant radiotherapy in Ontario between 2003 and 2012, following guideline publication.

RESUMO

OBJECTIVE: To analyze the efficacy and safety of surgery and endovascular management in treating Takayasu arteritis. METHODS: The data of 116 patients (24 males and 92 females; mean age (32±12) years) with Takayasu arteritis and underwent surgery or endovascular therapy was retrospective analyzed. According to the two different surgical procedures, the patients were divided into two groups: open repair group and endovascular repair group. One hundred and fifty-four surgical procedures were done including 69 cases of open repair and 85 cases of endovascular repair. A total of 211 arterial lesions were revascularized (open repair 114; endovascular repair 97). RESULTS: Among the 154 surgical procedures, 11(7.1%) presented a complication during perioperative period including 6(8.7%) of open repair and 5(5.9%) of endovascular repair. After a median follow-up of 38.5(0.5-142.0) months, three(4.3%) cases of stroke and death were observed in open repair group, two(2.3%) cases of stroke and 4(4.7%) cases of death were observed in endovascular repair group. At 1, 3, 5 and 10 years of follow-up, primary patency rate of open repair and endovascular repair were 95.0% and 89.3%, 84.3% and 69.8%, 73.3% and 56.3%, 53.4% and 48.1%, respectively; Primary assisted patency rate were 100% and 97.5%, 90.4% and 78.2%, 79.1% and 72.8%, 60.7% and 54.0%, respectively; Secondary patency rate were 100% and 98.8%, 95.6% and 92.7%, 85.8% and 78.1%, 74.8% and 58.0%, respectively. Cumulative survival rate were 97.0% and 100%, 97.0% and 97.6%, 97.0% and 90.6%, 91.3% and 84.5%, respectively (χ(2)=0.182, P=0.669). CONCLUSIONS: Both of the surgical revascularization and endovascular management are safe and effective in the treatment of Takayasu arteritis. Although long-term patency of endovascular therapy is low, it can be performed repeatedly and can be used as a preferred approach in treating a short stenosis. Surgical repair shows excellent long-term durability, it seems to be more suitable for complex lesions and failure cases of endovascular management.
