Background:Numerous studies have compared the accuracy of color Doppler (CD) with that of digital subtraction angiography (DSA) in the diagnosis of peripheral arterial disease (PAD). However, only a few have looked at the influence of these diagnostic tests on the treatment decision in PAD.Aim:This study evaluated the differences in treatment decisions that were based on CD and with those based on DSA findings.Methods and Materials:Findings from CD and DSA studies obtained in 40 patients were entered on line diagrams by two radiologists working separately. These were randomized and sent to three experienced clinicians – two vascular surgeons and one interventional radiologist. The treatment decisions of the clinicians based on each proforma were collected and analyzed to look for the degree of agreement between Doppler-based and DSA-based decisions.Results:There was fair to moderate agreement between CD-based and DSA-based decisions for all three clinicians, with some improvement in agreement with the addition of clinical data. The vascular surgeons showed better agreement with each other on treatment decisions compared to the interventional radiologist who showed a fair-to-moderate level of agreement with the vascular surgeons, which did not significantly change with the addition of clinical data.Conclusion:There is a fair to moderate agreement between treatment decisions based on CD findings and those based on DSA findings. We conclude that CD along with clinical data is sufficient to make decisions in the treatment of PAD.

“…3,4 Other authors recommend that DA be used only as a screening tool to help select patients who should then have CA before performance of any infrainguinal intervention. [5][6][7] Using DA alone to image the infragenicular arteries and plan bypass procedures has received increasing attention recently but is more controversial. Multiple studies have reported equivalent results when comparing DA with CA for imaging of the infrapopliteal arterial tree.…”
