it aleays DVT? evaluation of leg swelling with color doppler sonography

ABSTRACT

The aim of this study was to assess the value of duplex ultrasound examination in establishing diagnosis in swollen lower limbs. This study was conducted at the Department of Diagnostic radiology Mayo hospital Lahore. 50 consecutive patients presenting with leg swelling, submitted for colour Doppler sonography of the lower extremities were examined for deep vein thrombosis [DVT]. 46% of the patients were detected as having DVT, when examined through Doppler Ultrasonography. While 28% of the patients were not having any pathology in the limb.26% of the patients were having pathology other than DVT. The veins of the calf muscles are a common site of acute DVT and a source of pulmonary embolism. They should always be investigated in patients with leg swelling. Complete venous evaluation with duplex imaging can be very helpful in determination of underlying cause of the swelling
