SSEH is a rare cause of paraplegia. Early radiological diagnosis is crucial for timely neurosurgical management and saving patient from permanent neurological deficit or a fatal outcome.
Objective: To evaluate the efficiency of renal artery Doppler in diagnosis of secondary hypertension among cardiac patients.
Study Design: Analytical Cross-sectional study.
Place and Duration of Study: The present study was performed at Tertiary Care Center, Rawalpindi from Jan 2019 to July 2019.
Methodology: The study comprised of 50 patients with age range of 12-75 years with 90% confidence interval and 10% margin of error with prevalence of hypertension in Pakistan as 26.34%12. The study population included hypertensive patients referred for Doppler assessment of renal artery stenosis (RAS), in order to assess secondary cause of hypertension. The patients underwent angiography of kidneys within 14 days following Doppler assessment of RAS. The positive and negative outcome was presented as frequencies and percentages. The mean age was depicted as means ± standard deviation. The diagnostic features of specificity, sensitivity, negative predictive value and positive predictive values were calculated through a 2x2 table with angiographic findings considered as gold standard.
Results: In only 4(8%) patients bilaterally raised resistive index (RI) were evident. The diagnostic attributes of Doppler showed sensitivity of 48%, positive predictive value of 100% and diagnostic accuracy of 48%.
Conclusion: The role of renal artery Doppler in evaluating secondary hypertension has been over estimated. Thus, its application needs to be restricted for elderly patients to minimize time and cost expenses.
Objective: To assess the diagnostic accuracy of Magnetic resonance cholangiopancreatography (MRCP) in the detection of Choledocholith, taking post-operative findings as the gold standard.
Study Design: Cross-sectional validation study
Place and Duration of Study: Combined Military Hospital, Kharian Pakistan, from Jan 2020 to Jan 2021.
Methodology: Patients presenting with sonographic evidence of choledocholithiasis without any contraindications for magnetic resonance imaging were subjected to MRCP after informed consent. The patients who underwent surgery were followed up, and their per-operative findings were compared with the radiological findings of MRCP.
Results: A total of 87 patients were included in the study. The mean age of patients was 37.04±10.49 years (range of 22-65 years). The sensitivity for MRCP was 95%, specificity was 73.33%, positive predictive value (PPV) was 93.44%, and negative predictive value was 78.57%. The diagnostic accuracy for MRCP was found to be 90.66%.
Conclusion: The study shows that magnetic resonance cholangio-pancreatography is an effective imaging modality in diagnosing choledocholithiasis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
