This disorder includes both HV and IVC obstructions and hepatopathy. This study aimed to conduct a systematic review of the survival rate and clinical success of different types of endovascular treatments for Budd-Chiari syndrome (BCS). All participant studies were retrieved from four databases and selected according to the eligibility criteria for systematic review of patients with BCS. The survival rate, clinical success of endovascular treatments in BCS, and survival rates at 1 and 5 years of publication year were calculated accordingly. A total of 3398 patients underwent an endovascular operation; among them, 93.6% showed clinical improvement after initial endovascular treatment. The median clinical success rates for recanalization, transjugular intrahepatic portosystemic shunt (TIPS), and combined procedures were 51%, 17.50%, and 52.50%, respectively. The median survival rates at 1 and 5 years were 51% and 51% for recanalization, 17.50% and 16% for TIPS, and 52.50% and 49.50% for combined treatment, respectively. Based on the year of publication, the median survival rates at 1 and 5 years were 23.50% and 22.50% before 2000, 41% and 41% in 2000‒2005, 35% and 35% in 2006‒2010, 51% and 48.50% in 2010‒2015, and 56% and 55.50% after 2015, respectively. Our findings indicate that the median survival rate at 1 and 5 years of recanalization treatment is higher than that of TIPS treatment, and recanalization provides better clinical improvement. The publication year findings strongly suggest progressive improvements in interventional endovascular therapy for BCS. Thus, interventional therapy restoring the physiologic hepatic venous outflow of the liver can be considered as the treatment of choice for patients with BCS which is a physiological modification procedure.</p>","PeriodicalId":15512,"journal":{"name":"Journal of Clinical Imaging Science","volume":"13 ","pages":"5"},"PeriodicalIF":0.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/dc/0d/JCIS-13-5.PMC9899460.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9243997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Material and Methods: Two hundred and eighteen lumbar MRIs from the Picture Archiving and Communication System were reviewed. These were collected from three main governmental hospitals, in North, Central, and South of Jordan. The mid-sagittal diameters of the vertebral body, spinal canal, and dural canal area were measured at all levels. Patients’ gender and age were documented as well. Exclusion criteria were kyphoscoliosis alignments disorders, lumbar spinal canal compression regardless of the cause, vertebral bony disease (including fractures), and the presence of technical artifacts. Statistical analyses used descriptive and correlational methods. Comparisons were made between genders, age groups, lumbar level, dural sac area in the study population using independent t-test and one-way ANOVA tests, and between ethnicities by reviewing previous reports on subjects of different ethnicities. Results: The mean TPR ratio for the study participants was 0.4502 ± 0.097. The value of TPR was widest in the 20–29-year-old group at all vertebral levels and in both males and females. Females had a significantly wider TPR than males (P = 0.003) in all age groups. TPR differed significantly between the five vertebral levels (P = 0.026). The difference in TPR between age groups was not statistically significant. TPR showed a positive significant correlation with dural sac (r = 0.203, P = 0.003). Comparison with the previous literature demonstrated variation in the TPR where Jordanian population had a lower TPR in comparison with Negros and Caucasoids whereas similar to Koreans, especially in females. Conclusion: There are significant differences in TPR according to gender, dural sac area, lumbar spinal level (except between L1 and L2), and ethnic group, but no significant difference with the age was found. The present study has identified normal values of Torg’s ratio in the Jordanian population. Although the study may not be able to provide clear guidelines for use in clinical practice, it has still highlighted possible between countries variations and has identified differences in these values to different factors. Implications on clinical practice could be reflected on the diagnosis of lumbar spinal stenosis or on predicting the prognosis of lumbar spine injury.","PeriodicalId":15512,"journal":{"name":"Journal of Clinical Imaging Science","volume":" ","pages":"53"},"PeriodicalIF":0.9,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/5a/77/JCIS-12-53.PMC9610521.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40677862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
