Objective: To determine frequency of sapheno-femoral junction (SFJ) and sapheno-popliteal junction (SPJ) incompetence on duplex ultrasonography in patients with varicose veins.Study Design: Cross-sectional study.Place and Duration of Study: Shaikh Khalifa Bin Zayed Al-Nahyan/Combined Military Hospital, Rawalakot, Azad Jammu & Kashmir, from Aug 2019 to Feb 2020.Methodology: A total of 70 patients were selected using non-probability, consecutive sampling. After ethical approval, informed consent and relevant history taking, duplex ultrasonography (DUS) was done in standing and supine positions in patients with varicose veins, fulfilling inclusion and exclusion criteria. Presence or absence of SFJ and SPJ incompetence was assessed.Results: Mean age was 41.99 ± 11.08 years with 36 (51.43%) patients between 36-50 years. Mean duration of disease was 6.33 ± 2.29 months while 47 (67.14%) patients had symptoms for more than 6 months at the time of presentation. Occupation wise, 40 (57.14%) patients were field workers while 30 (42.86%) were office and domestic workers. Isolated SFJ, SPJ and combined junction incompetence were found in 27 (38.57%), 20 (28.57%) and 23 (32.86%) patients respectively. Both SFJ and SPJ incompetence were more in obese patients (78.6% and 71.4% respectively) as compared to non-obese patients. Conclusion: Frequency of SFJ incompetence was more than SPJ incompetence on DUS. Obesity, male gender and prolonged motionless standing predispose to the development of varicose veins. Preventive measures and early diagnosis can decrease disease burden.

Objective: To determine the diagnostic accuracy of real-time Shear Wave Elastography (SWE) in detecting liver cirrhosis among patients suffering from diseases predisposing to it, keeping histopathology as the reference standard. Study Design: Cross-sectional study. Place and Duration of Study: Armed Forces Institute of Radiology and Imaging, Rawalpindi, from Jan 2018 to Jul 2018. Methodology: A total of 114 patients were recruited, and relevant history taken from patientsreal-time shear wave elastography (SWE) of the liver was performed, followed by USG guided liver biopsy. Patients having clinically suspected diseases predisposing to hepatic fibrosis were sent to the Radiology department for ultrasound or ultrasound-guided liver biopsy. Elasticity values using sheer waves of 14.9 kPa (2.23m/s) or more was taken as suggestive of cirrhosis. Elastography findings were compared with histopathology findings.Results: Real-time SWE showed high diagnostic accuracy for detecting liver cirrhosis with sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of 92.86%, 89.66%, 89.66%, 92.86% and 91.23%, respectively. Conclusion: This study concluded that the diagnostic accuracy of RTSW elastography in detecting liver cirrhosis is relatively high.
