Résumé
With the technologic advancement in vascular ultrasound imaging, surgeons are now encouraged to perform their own examinations. The vascular surgeons run the vascular laboratory in Suez Canal University hospital.The aim of this study to determine the efficiency and advantages of the arterial duplex scanning performed by the surgeon. A prospective comparative study between the results of colour duplex [performed by vascular surgeon], arteriogram and operative finding in 105 limbs [96 lower and 9 upper] from 63 patients, with chronic arterial occlusive disease or peripheral arterial emergencies, was performed. The arterial vessels were divided into 13 segments. A total of 858 segments were examined. Duplex scan was able to detect significant disease with sensitivity 83%, specificity 100% positive predictive index 100%, negative predicative index 93%, accuracy 95% and K value of 0.85. Accuracy for final therapeutic decision was 83% in arteriography, 80% in duplex and combination of both was 100%.Surgeon performed duplex is reliable and should be an integral part of vascular surgeon's practice. Our practice recommends performing arteriogram as well in the lower limb to maximize preoperative information. This paper is accepted for presentation in the first congress of the North African and Middle East chapter of the international union of angiology. Cairo, Egypt- October 2001
