The aim of this study was to evaluate the feasibility and effectiveness of multi-slice computed tomography (MSCT) angiography for the assessment of traumatic lesions involving the arteries of the lower limbs.
Forty-seven patients with suspected arterial post-traumatic lesions of lower limbs underwent MSCT angiography (4 x 2.5-mm collimation, 3-mm slice width). The standards of reference were: digital subtraction angiography (DSA; patients with inconclusive/doubtful or positive MSCT angiography indicating a need for intravascular treatment), surgical findings (patients with positive MSCT angiography indicating a need for surgery), or clinical/investigational follow-up (patients with negative MSCT angiography and no need for further diagnostic procedures or surgery).
All CT exams were technically adequate. Sensitivity, specificity, and overall diagnostic accuracy of MSCT angiography were 96.3, 90, and 93.6%, respectively, relative to the reference of standard findings. In 44 out of 47 patients, MSCT angiography allowed a correct continuation of the diagnostic work-up.
MSCT angiography is a reliable fast tool for diagnosing traumatic vascular lesions, providing results comparable to DSA.
本研究旨在评估多层螺旋计算机断层扫描(MSCT)血管造影术在评估下肢动脉创伤性病变中的可行性和有效性。
47例疑似下肢动脉创伤后病变的患者接受了MSCT血管造影检查(准直4×2.5毫米,层厚3毫米)。参考标准为:数字减影血管造影(DSA;MSCT血管造影结果不确定/可疑或阳性且表明需要血管内治疗的患者)、手术结果(MSCT血管造影阳性且表明需要手术的患者)或临床/研究随访(MSCT血管造影阴性且无需进一步诊断程序或手术的患者)。
所有CT检查在技术上均足够。相对于标准检查结果参考,MSCT血管造影的敏感性、特异性和总体诊断准确性分别为96.3%、90%和93.6%。47例患者中有44例,MSCT血管造影能够使诊断检查正确延续。
MSCT血管造影是诊断创伤性血管病变的可靠快速工具,其结果与DSA相当。
