Comparing Color Doppler Ultrasonography and Angiography to Assess Traumatic Arterial Injuries of the Extremities

Abstract

Background:Traumatic events are one of the major causes of arterial injuries. Physical examination is not a good predictor of the extent of injuries and arteriography is considered as the gold standard for this purpose. In the recent years, noninvasive modalities are increasingly replacing diagnostic arteriography. Color Doppler ultrasonography (USG) is an excellent method to investigate arterial diseases.Objectives:The present study aimed to evaluate the diagnostic value of color Doppler USG compared to conventional angiography in traumatic arterial injuries of extremities.Patients and Methods:Seventy-five patients with extremity trauma suspicious for arterial injury were examined by color Doppler USG just before angiography. Doppler pattern and flow states were assessed, then angiography was performed. The results of duplex USG were compared with angiography.Results:Color Doppler USG had a sensitivity of 95% and specificity of 98% in diagnosis of arterial injury. Positive and negative predictive values of Doppler USG were 92.5% and 94.2%, respectively.Conclusions:Color Doppler USG can be used as a reliable modality with acceptable sensitivity and specificity values to screen hemodynamically stable patients with limb trauma suspicious for arterial injury.

Diagnostic value of four-dimensional CT angiography in arterial erectile dysfunction using 320-detector row dynamic volume CT

“…A flow rate of 30 cm/s or higher PSV represented normal arterial flow while a rate of 25 cm/s or lower PSV was considered to be arterial insufficient hence causing ED, and together with a normal arterial response, EDV > 6 cm/s and RI < 0.6 were considered to be normal [ 8 ]. In consistency with our findings, Pezeshki Rad et al [ 25 ] demonstrated that both sensitivity and specificity of CDDU in diagnosing traumatic limb vascular injury was much higher, proving that CDDU is a promising tool in screening and diagnosis. Additionally, all patients in the EHS 1/2 group had a single-peak spectrum in systole with no or a rather low spectrum of blood flow in diastole, while patients in the EHS 3/4 group all had an increased blood flow spectrum in both systole and diastole after erection.…”

Limb salvage after delayed arterial repair in compound Grade III C fracture humerus: a case report

“…4,5,7,8 In our case also, the limb survived because of collateral circulation through the profunda brachii artery.…”

“…7 However, this has its own disadvantages like time delay in shifting the patient to radiology department, expensive, etc. The alternative is doppler USG which has sensitivity of 95% and specificity of 92%.…”

Evaluation of sensitivity and the specificity of Canadian CT head rule and New Orleans criteria in patients with head injury

“…20 per cent of individuals who have suffered such damages are hospitalized, of which 200,000 death or permanent disability are created. 11,12 Damage to the head (head trauma) is the main cause of traumatic death in patients less than 25 years old and includes about one third of trauma deaths are. 13 In this study, the variable of trauma mechanism is a qualitative variable in which the highest frequency belongs to automobile driver (35.5 per cent) and the lowest frequency to Falling (9.4 per cent).…”
