THE USE OF MULTISPIRAL COMPUTED TOMOGRAPHY IN THE DIAGNOSIS OF OBLITERATING DISEASES OF THE ARTERIES OF THE LOWER EXTREMITIES

Obliterative arterial disease of the lower extremities (OALD) is one of the most common forms of vascular pathology,leading to chronic tissue ischemia, pain, and significantly increasing the risk of patient disability.Multislice computed tomography (MSCT) is currently considered one of the most accurate, informative, and accessible methods for visualizing the vascular system.It not only identifies the presence and degree of arterial stenosis but also allows for a detailed assessment of the extent of the lesion and collateral circulation.The aim of this study is to evaluate the diagnostic efficacy of MSCT in OAD,as well as a comparative analysis with other imaging methods, such as duplex ultrasound (US) and traditional angiography.下肢闭塞性动脉疾病（Obliterative arterial disease of the lower extremities, OALD）是最为常见的血管病理类型之一，可引发慢性组织缺血、疼痛，并显著提升患者的致残风险。多层计算机断层扫描（Multislice computed tomography, MSCT）目前被公认为可视化血管系统的精准度最高、信息最丰富且可及性最强的检查方法之一。该技术不仅可明确动脉狭窄的存在情况与狭窄程度，还能详细评估病变范围及侧支循环状态。本研究旨在评估MSCT用于OAD诊断的效能，并与双功超声（duplex ultrasound, US）、传统血管造影等其他影像学检查方法开展对比分析。
