Abstract
The evaluation of the whole arterial system is necessary before peripheral vascular intervention. To judge the run off. And to plan the localization of the peripheral anastomosis.
Although, angiography is generally safe, it is an invasive technique and is associated with complications. The complication rate varies depending on whether a transfemoral or transaxillary approach is used.
Today, color Doppler sonography is the first choice for the diagnosis of vascular disorders.
Duplex imaging provides information on both the anatomical site and hemodynamic impact of individual atherosclerotic lesions. whereas the arteriography gives only anatomical information.
The accuracy of clinical decision base on duplex imaging compared with that based on intra-arterial DSA was 94% this suggests that preoperative arteriography provides no additional diagnostic benefit over color Doppler sonography.
The use of intraoperative duplex scanning reduces the incidence of surgical technical defects that could threaten graft patency. Occasionally, duplex ultrasound is unable to differentiate between a very tight stenosis and total occlusion. In high grade stenosis the flow velocity falls to a lower level and may be undetected unless the Doppler detecting system is adjusted correctly by the investigator.
MRA has higher incidence to detect distal runoff vessels which can be explained by non dependence on delivery of contrast media which sometimes prevents visualization of distal vessels in cases of severe proximal vascular disease, image
