ABSTRACT
Background and Aims: Cesarean scar pregnancy (CSP) is a rare medical condition accounting for 1:2000 of all pregnancies with prior history of cesarean deliveries (CS). As the rate of CS is increasing worldwide, it is important to know the nature of CSP and its complications. Methods: In this retrospective case-control study, we evaluated 264 pregnant women; 86 cases with ultra-sonographic findings of CSP and 178 controls: normal pregnancies with gestational age less than 12 weeks. The variables consisted of demographic characteristics, the features and causes of the prior CS, the time distance to the current pregnancy, sonographic features, and the final management. All data analyzed using SPSS version 21. Results: There was a significant difference between the two study groups regarding to parity, abortions and D&Cs (p < 0.001). In the case group, 19.8% of patients had positive results for STDs versus 16.3% in the control group (p > 0.990). The mean average of intervals between the last CS and current pregnancies were 48.22 ± 37.03 in the case group versus 61.25 ± 36.25 months in the control group (p < 0.001). Regression Logistic analysis showed advanced maternal age (p < 0.001), positive history of abortions and D&C (p < 0.001), elective type of prior c/s (p < 0.001) and the short time interval between prior CS and current pregnancy (p < 0.001) could significantly predict the patients at higher risk of presenting CSP in the case group. Conclusions: Based on our findings, advanced maternal age, positive history of abortion, the elective type of the former CS, and short time intervals between previous CS and current pregnancy are the main risk factors of CSP.
ABSTRACT
BACKGROUND: This study was designed to evaluate and compare the diagnostic value of magnetic resonance imaging (MRI) and indirect magnetic resonance arthrography (I-MRA) imaging with those of arthroscopy and each other. METHODS: This descriptive-analytical study was conducted in 2020. All patients who tested positive for labrum lesions during that year were included in the study. The patients underwent conservative treatment for 6 weeks. In the event of no response to conservative treatment, MRI and I-MRA imaging were conducted, and the patients underwent arthroscopy to determine their ultimate diagnosis and treatment plan. Imaging results were assessed at a 1-week interval by an experienced musculoskeletal radiologist. Image interpretation results and arthroscopy were recorded in the data collection form. RESULTS: Overall, 35 patients comprised the study. Based on the kappa coefficient, the results indicate that the results of both imaging methods are in agreement with the arthroscopic findings, but the I-MRA consensus rate is higher than that of MRI (0.612±0.157 and 0.749±0.101 vs. 0.449±0.160 and 0.603±0.113). The sensitivity, specificity, negative predictive value, positive predictive value, and accuracy of MRI in detecting labrum tears were 77.77%, 75.00%, 91.30%, 50.00%, and 77.14%, respectively, and those of I-MRA were 88.88%, 75.00%, 92.30%, 66.66%, and 85.71%. CONCLUSIONS: Here, I-MRA showed higher diagnostic value than MRI for labral tears. Therefore, it is recommended that I-MRA be used instead of MRI if there is an indication for potential labrum lesions.
