Abstract

BackgroundIn this study, we evaluated the accuracy of the indocyanine green angiography (ICGA) test to diagnose peripheral arterial disease (PAD) with isolated infrapopliteal lesions.MethodsThis study was undertaken from a retrospective review of PAD patients with isolated infrapopliteal lesions who underwent ICGA between November 2012 and July 2013. We calculated the ICGA parameters while comparing the findings with the ankle-brachial index (ABI) and toe-brachial index (TBI) in patients with infrapopliteal lesions.ResultsTwenty-three limbs with isolated infrapopliteal lesions in 14 PAD patients and 15 limbs without arterial lesions in 9 control patients were examined using ABI, TBI, and ICGA. The Td 90% (the time elapsed from the maximum intensity to 90% of the maximum intensity) correlated most significantly with the ABI value. A cutoff value of Td 90% >25 sec also significantly correlated with the presence of PAD (sensitivity, 82.6%).ConclusionsICGA might therefore be useful for assessing the peripheral perfusion quantitatively, even in PAD patients with isolated infrapopliteal lesions. The use of Td 90% on ICGA may also be effective for accurately estimating the presence of PAD.
