无损伤血管检查ABI,Duplex,MRA诊断下肢动脉硬化闭塞症

目的:探讨无损伤性血管检查的准确性以及用无损伤性血管检查代替常规血管造影的可能性.方法:本组病例同时采用3种无损伤性血管检查法,包括踝/肱指数测定、彩色超声扫描、磁共振血管显象,并与手术探查结果相对照,以观察无损伤性血管检查的准确性.结果:在本组14例中,用3种不同的无损伤性血管检查法诊断下肢动脉硬化闭塞症,其结果均相符合,除3例未手术外,余11例经手术探查,结果也完全符合.3种无损伤性血管检查中以MRA最为准确、直观,可显示病变的程度、位置和范围的解剖学图象,提供手术治疗的依据.结论:通过本组观察ABI、Dup-lex、MRA3种无损伤血管检查法的综合检查结果,说明三者的结合可代替常规的下肢动脉造影检查,此是近年血管检查方面的一个突破性进展.

Atherosclerotic Occlusive Disease of the Lower Extremities Diagnosed by Non-invasive Blood Vessel Detection Method-Ankle Brachial Index, Duplex and Magnetic Resonance Angiography

To study the accuracy of non-invasive blood vessel detection methods and the possibility of these detection methods instead of conventional angiography. Methods: In 14 patients with possible atherosclerotic occlusive disease of the lower extremities, non-invasive blood vessel detection methods including ankle brachial index(ABI), Duplex and magnetic resonance angiography-(MRA) have been performed in order to evaluate their accuracy. Results: Overall concordance was evidenced among the three non-invasive blood vessel detection methods and the operative finding in this study. MRA is an accurate blood vessel detection method for severe atherosclerotic occlusive diseases of lower extremity, it can show the stenosis, degree of the location and the length of lesions. Conclusions: Clinical assessment of ABI, Duplex and MRA showed that the use of these methods in combination can take the place of conventional angiography for severe atherosclerotic occlusive disease of the lower extremity. This is a great improvement method in the detection of vascular lesions.
