Abstract
Background; The new clinical entity, known as aorto-iliac atherosclerosis obliterans or aorto-iliac and lower extremities arteries occlusive disease is one of the most frequent clinical problems confronted by vascular surgeons today.
The abdominal aorta and iliac arteries being amongst the arterial segments most commonly affected by atherosclerosis (kumar et al., 2005). Objectives; The aim of this study is to compare the MSCT angiography as a recent non invasive imaging modality for investigating aorto-iliac arterial disease to DSA Methods & Results;Digital subtraction angiography is considered the gold standard technique in assessment of these arteries.
The major advantage of DSA are high spatial resolution images and temporal information regarding delayed filling of the vasculature of interest. However, the invasiveness of the procedure, and radiation exposure led to the need for less and non-invasive imaging techniques .MSCT angiography, has proved to be a less invasive and a reliable method of investigating the lower limb arterial disease with results comparable to DSA . MSCT angiography as a less invasive imaging modality may be used for preoperative assessment of lower limb arterial disease.
Conventional angiography may be spared for patients who are candidate for interventional procedures e.g angioplasty or stent application. Conclusion; MSCT a rapid, relatively non invasive method for assessing the aortic and femoropopliteal segments, It can be performed in fraction of time required for catheter angiography. It can provide view of the aorta and femoropopliteal segment that are simply not possible with any other modalities.
