Abstract

Objectives: To establish the accuracy and identify advantages and disadvantages of colour duplex imaging compared with venography in the diagnosis of symptomatic proximal deep vein thrombosis (DVT) in our centre.

 

Design: Prospective study over a 15 month period.

 

Patients: 34 patients with 35 DVT suspected lower limbs were studied. They were first studied with colour duplex ultrasonography and the findings compared with contrast venography of the suspect limb.

 

Results: 17 venograms were positive for DVT and ultrasound was positive in all. There was one false positive ultrasound examination. Sensitivity and specificity for detection of proximal DVT was 100% and 94.4% respectively. Venography resulted in complications in 6 patients (phlebitis 4, skin ulceration 2). Additional diagnoses were possible with sonography (calf haematoma 1, calf neoplasm 1, deep venous reflux 2 and superficial venous reflux 5).

 

Conclusion: Colour coded duplex sonography is highly accurate and safe in detecting femoropopliteal thrombosis. Venography should be reserved only for duplex inconclusive situations.
