COMPARATIVE EVALUATION OF COLOR DOPPLER AND CONVENTIONAL DIGITAL SUBSTRACTION ANGIOGRAGRAPHY IN SUPRGENICULAR ARTERIAL DISEASE: A PROSPECIVE COMPARATIVE STUDY

Le résumé fourni par la source

AIMS AND OBJECTIVES:To evaluate and correlate the findings of CD with arteriography as the gold standard, in PAOD of the lower extremities in supra-genicular part and to define whether color Doppler, is an alternative or an adjunct to DSA.SETTINGS AND DESIGN: This prospective study was designed in the department of Radiodiagnosis G.R. Medical college Gwalior Madhya-Pradesh.+ Patients were subjected to CFD scan followed by arteriography, to evaluate the lower limb arteries.MATERIALS AND METHODS: Those Patients who were due for DSA were subjected to CD scan followed by arteriography, to evaluate the lower limb arteries.50patients of PAOD formed the subjects and their affected lower limbs evaluated by CD and arteriography, for localization and grading of lesion in the arteries, into normal/insignificant stenosis, significant stenosis and occlusion.The results were analyzed in a blind fashion in a total of 58 limbs comprising of 300 vascular segments.Statistical Analysis: Results were analyzed by two way contingency tables, using calculator, and SSP software.RESULTS: There was good statistical agreement and sensitivity of CD was 91%specificity was 97%, PPV was 87%, and NPV was 98%in supragenicular part.CONCLUSION: The agreement between CD and DSA was generally good, irrespective of the severity of ischemia.CD performed well compared with DSA.Hence color Doppler can be an alternative to DSA in diagnosing peripheral arterial occlusive diseases in supragenicular part of lower limb arteries.
