The use of duplex ultrasound arterial mapping as an alternative to conventional arteriography for primary and secondary infrapopliteal bypasses

Evaluation of various image reconstruction parameters in lower extremity stents using multidetector-row CT angiography: initial findings

“…Duplex ultrasound of arteries is the most commonly used technique for follow-up examinations after artery stenting and peripheral bypass surgery [4,5]. It is a cost-effective method and available almost everywhere, but the reproducibility of the ultrasound results may be difficult.…”

New simple image overlay system using a tablet PC for pinpoint identification of the appropriate site for anastomosis in peripheral arterial reconstruction

“…The target artery and its branches are overlaid as a red (a) or blue (b) line on a study done to evaluate the potential of an image overlay system in peripheral vascular surgery. The advantages of US include that it is noninvasive, it does not involve radiation exposure, and it provides hemodynamic information as well as morphological data [9][10][11]. On the other hand, its utility is limited because it requires more time than other imaging modalities and its quality is operator-dependent [6][7][8][9]12].…”

“…The incision site for distal anastomosis in crural or pedal bypass surgery is often established preoperatively using color-assisted duplex ultrasonography (US) with reference to the results of these imaging examinations [3][4][5][6][7][8][9][10][11]. However, precise identification of the arterial portion for distal anastomosis using US is sometimes difficult, because of severe arterial calcification or the depth of the target vessel [10], and its accuracy is dependent on the skills of the operator [6][7][8]12].…”

Ultrasound Imaging in Vascular Diseases

“…However, in recent years, duplex ultrasonography (DA) has gained a major role in the pre-operative evaluation of patients undergoing lower extremity bypass (Ascher et al, 1999;Grassbaugh et al, 2003;Ligush et al, 1998;Pemberton et al, 1996;Proia et al, 2001). Mazzariol et al reported that the use of dupplex ultrasonography can provide enough information for surgery in more than 83% of patients with arterial stenosis and that an abnornal femoral artery waveform was 100% predictive for detecting stenosis greater than 80% (Mazzariol et al, 2000) Proia et al have also confirmed these results (Proia et al, 2001).…”
