“…PSV ratios for this degree of stenosis have been reported from 1.8 to 2.5 in a range of studies for aorto-iliac and femoropopliteal disease, although a ratio of 2.0 is most commonly reported and used. 32,33,39,40 The range reflects differences of interpretation in ultrasound and arteriography measurements and illustrates the problem inherent in defining a stenosis by its diameter. A study to examine progression of femoral artery disease 41 observed that stenoses with velocity ratios >3.0 had a high incidence of early occlusion and that at this level early intervention is advised.…”

“…The utility of aorto-iliac duplex ultrasonography (DUS) in the screening for AI disease has been controversial. Langsfeld et al evaluated DUS in 23 patients with angiographically confirmed aortoiliac stenosis and found a sensitivity of 82% and specificity of 93% for detection of severe occlusive disease by DUS, whereas others have found aortoiliac disease more difficult to diagnose accurately (positive diagnostic value of 60%) compared to the detection of carotid or renal arterial disease (positive diagnositic value of 80%) (24,25). DUS was used in over 1000 candidates for renal transplantation by Voiculescu et al (5), who found that pulsus parvus et tardus waveform, low pulsatility index, and monophasic signal distal to the stenosis were present in all patients with AIOD.…”

As the average age of a renal transplant candidate increases, the challenge of managing recipient vascular disease affecting renal allograft function will become more common. Pre-operative screening can reveal the presence of atheromatous disease that could adversely affect allograft transplantation and function, but parameters for successful screening have not been established. Treatment options include pre-operative revascularization, concurrent therapy or delayed revascularization. Endovascular therapies have burgeoned but surgical correction is still required for some of the more complex, long-segment lesions. Potential surgical interventions range from endarterectomy to aorto-iliac bypasses. We present a case of immediate post-operative revascularization using a femoro-femoral bypass to salvage a renal allograft. The literature is reviewed to assess best practices for detecting peripheral vascular disease in renal transplant candidates and subsequent management options.

“…Other studies using B-mode imaging have compared duplex scanning with intraarterial digital subtraction angiography for the diagnosis of lower limb arterial disease. [7][8][9][10][11] The usefulness of duplex scanning in the selection of patients for endovascular therapy has also been reported. 12,13 The results of a large study 14 further highlighted the efficacy of color-flow duplex imaging of lower limb arteries (iliac, femoropopliteal, and crural) compared to intraarterial angiography.…”
