There has been an increase in the use of cryoablation in the management of musculoskeletal lesions, in particular fibromatosis. Aim  This study aimed to measure the average and relative increase in size of the cryoablation ice ball after the first (10 minutes) and second freeze cycles (20 minutes) to accurately predict the size of the ice ball between first and second freezes to help prevent any unwanted damage of the nearby skin and neurovascular structures. This is especially important when ablating in relatively small body parts such as in the appendicular skeleton. Material and Methods  Eight patients treated with cryoablation over a 12-month period for fibromatosis were, included in the study. The size and volume of the ice ball were measured during the first and second cycle of cryoablation. Results  The average patient age of the cohort was 35.6 years old (min 28 and max 43). There was female predominance in the study (3:2, F:M). There was a significant increase (26%) in the linear dimensions and almost doubling in the volume of the ice ball between freeze cycles ( p -value = 0.0037 for dimensions and p -value = 0.0002 for volumes). Conclusion  This pilot study is a preliminary attempt to predict the eventual size of the ice ball during cryoablation procedures when treating cases of fibromatosis. This should help in planning cryoablation to ensure decrease morbidity by preventing injury to adjacent critical structures (neurovascular bundle and skin).","PeriodicalId":51597,"journal":{"name":"Indian Journal of Radiology and Imaging","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/fb/6b/10-1055-s-0043-1764466.PMC10289866.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10075350","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}

A multivariate logistic regression model was used to explore associations of abnormal Doppler and AFV with preterm birth. The diagnostic effectiveness of Doppler and amniotic fluid measurements for preterm births was assessed. <b>Results</b>  One hundred and sixty-one (25.6%) of the 630 women had a preterm birth before 37 gestational weeks. Eighty (21.1%) of the 379 women with normal AFV and normal fetal Doppler studies in the third trimester had a preterm birth. The proportion of preterm birth declined from 35.14% in 2019 to 19.53% in 2022 (chi-square test <i>p</i>  = 0.009). Preterm birth was associated with preterm PE (adjusted odds ratio: 3.66, 95% confidence interval: 1.42, 9.44) in a multivariate logistic regression model. Both abnormal fetal Doppler and AFV did not have a good discriminatory ability for preterm births. <b>Conclusion</b>  Integration of fetal Doppler studies helped reduce the preterm birth rate by providing an objective measure of fetal well-being, contrary to a common belief that the use of color Doppler in the third trimester may result in iatrogenic increased preterm birth. Preterm births are associated with preterm PE and early identification of high-risk women and early initiation of low-dose aspirin may have an added benefit on preterm birth rates.</p>","PeriodicalId":51597,"journal":{"name":"Indian Journal of Radiology and Imaging","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/2f/5f/10-1055-s-0043-1764465.PMC10289862.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9715040","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}

Postbiopsy and prior to withdrawing the coaxial cannula a CT data set was obtained to detect and quantify pneumothoraces as mild, moderate, and severe. In all asymptomatic cases of mild pneumothorax simple observation was done. In all asymptomatic cases of moderate pneumothorax, immediate needle aspiration was performed. In all symptomatic cases, cases with severe pneumothorax, and cases with progressively enlarging pneumothorax small caliber 6 to 8F pigtail catheters were inserted. <b>Results</b>  Ninety-one cases had mild pneumothorax, 42 had moderate pneumothorax, and 18 had severe pneumothorax. In the 91 patients of mild pneumothorax only 1 (1%) patient showed increase in size of pneumothorax on follow-up requiring catheter insertion. In the 42 cases of moderate pneumothorax, which were managed by simple aspiration of pneumothorax, 4 (9.5%) cases showed increase in size of pneumothorax on follow-up.

The mean duration of catheterization in our study was 3.74 ± 1.09 days. <b>Conclusion</b>  Majority of pneumothoraces are benign and do not require any intervention, just observation. Manual aspiration is an effective way of treating moderate pneumothoraces with success rate of 90%, thereby reducing the number of cases requiring catheter insertion; however, close observation is required as few cases may progress to severe pneumothorax and require pigtail insertion.
