The Added Value of Multislice CT Venography in Pre-Operative Assessment of the Deep Venous System of Both Lower Limbs; Correlation with the Doppler/US Findings

Abstract
Background: Deep venous thrombosis is very common disease affecting the public health, so proper assessment and treatment improve the quality of patient's life. In addition DVT may cause pulmonary arterial thrombo-embolism.
Aims of the Study: To assess the value of CT venography in detailed assessment of the lower extremities deep venous system in comparison with the Doppler US findings for patients with swollen limbs referred from vascular clinics.
Patients and Methods: The study was carried over sixty patients (19 males and 41 females, age range 21-56 year old) from November 2016 to December 2017. Detailed evaluation of all examined patients was done using Doppler/US by experienced sonologist and multislice CT venography with calculation of the body mass index for each patient.
Results: Sixty patients (19 males and 41 females, age range 21-56 year old), body mass index range (20-34), Doppler findings showed that 54 patients were free of deep venous thrombosis and 6 patients with chronic deep venous thrombosis. However, multislice CT venography showed that 48 patients were free of deep venous thrombosis and 12 patients with chronic deep venous thrombosis. Also according to these results patients are classified as primary and secondary varicose veins.
Conclusion: Based on our results, multislice CT venog-raphy is a non operator dependant technique adding great clinical value in assessment of the patency and detailed delineation of the deep venous system, especially the abdominal and pelvic veins.
