“…Blagojevic et al., 23 Haigang et al., 24 and Abd-Elgawad et al. 25 highlighted the clinical diagnosis, treatment, and research of lower extremity artery disease, in which DSA technology could be used to accurately assess blood circulation and define the location of the affected vessels and affected areas of tissue. These capabilities play an indispensable role in the formulation of treatment plans, even in the case of amputation, since DSA can provide a more reliable reference standard, thus reducing the amount of amputated tissue and allowing as much limb function to be preserved as possible.…”

Objectives Research in the field of lower extremity vascular disease has increased in popularity over the years. To adequately characterize and validate the effectiveness of vascular interventions, in vivo experimentation in large animals is required. Thus, it is necessary to find a method to detect the shape and density of blood vessels in the lower extremities that can evaluate and verify the treatment measures’ effectiveness and have high accuracy and repeatability. This study characterized factors that determined both the accuracy and overall value of digital subtraction angiography in lower limb arteriography using a canine animal model. Methods Six beagle dogs were anesthetized and immobilized on the motorized table. The femoral artery was accessed using an indwelling needle. A bolus of contrast agent was injected into the access site, and digital subtraction angiography with bolus chase technology was used to collect contrast images for analysis. At the end of the procedure, the anesthetized dogs were euthanized using an overdose of potassium chloride. After confirming the euthanasia of the dogs, the cadavers were taken to the experimental animal center of Xinjiang Medical University and processed by qualified institutional personnel. Results The final arteriographic images of the hind limbs from all six dogs were precise, and the branches of small vessels could be distinguished without any visible artifacts. Conclusions These results suggested that arteriography using digital subtraction angiography could reveal the shape and density of blood vessels in canine animal models. This method has great potential to significantly improve research related to limb ischemia due to its simple and reproducible results.

“…Computed tomographic (CT) angiography is increasingly used for diagnostic imaging in patients with peripheral arterial disease. The use of multidetector row technology has resulted in shorter acquisition time, increased volume coverage, lower dose of contrast medium, and improved spatial resolution for assessing small arterial branches (5) .…”

Purpose: To assess the diagnostic accuracy of multi-detector CT angiography in the assessment of lower extremity arterial diseases by comparing the results with the standard of reference, conventional angiography. Patients and Methods: The studied group included 140 patients with suspected diagnosis of lower limb arterial disease on the basis of clinical examination or Doppler study with no age or sex predilection between March 2011 and November 2013. All patients were evaluated with lower limb angiography by multi-detector computed tomography and conventional angiography. The data obtained was statistically analysed to assess the accuracy of diagnosis of lower limb arterial diseases by MDCT angiography compared to conventional angiography that described in terms of count and percentage. Results: MDCT angiography findings showed 90.3% overall agreement with CA findings regarding the degree of stenosis while regarding the stenosis length MDCT angiography results showed 87.5% overall agreement with CA results. The overall sensitivity of MDCT angiography was 94.5%, specificity was 92.2%, and accuracy was 95.3%. Conclusion: Multi-detector row CT angiography can be used as an alternative to conventional angiography in the evaluation of aortoiliac and lower extremity arteries in patients with peripheral arterial disease.

Background: CT Angiography (CTA) of aortoiliac and lower extremity arteries is a relatively recent innovation of CT imaging that has changed after the introduction of multi-detector row scanners. Objective: The study aimed to evaluate the diagnostic accuracy of Multidetector Computed Tomographic Angiography (MDCTA) in the assessment of arterial tree in patients with Peripheral Arterial Occlusive Disease (PAOD), as compared to Digital Subtraction Angiography (DSA). Methods: A single-center nonrandomized prospective study was conducted on 50 patients complaining of peripheral arterial disease (chronic stage) from February 2017 to October 2017. All the patients were exposed to DSA and CTA prior to definitive treatment. The images were then analyzed using maximum intensity projection, volume-rendered, and curved multiplane reformation techniques. Results: All the patients involved in this study were susceptible according to their clinical presentation. The statistical analysis exposed a highly significant difference between CTA and DSA in the assessment of stenosis at the level of Femoropopliteal segment (P<0.01), while for infrapopliteal segment, there was no statistically significant difference between CTA and DSA having 8% versus 14% insignificant stenosis and 62% versus 47% significant stenosis in CTA and DSA, respectively. The overall accuracy of CT angiography in the femoropopliteal segments was 95.20% while in the infrapopliteal segment it was 94.5%. Conclusion: Multidetector CT angiography was found to be a reliable alternative mean for pathoanatomical description of the arterial lesions in critical lower limb ischemia and its subsequent management in comparison to digital subtraction angiography.
