How fluorescence angiography illuminates the potential for limb salvage
from Podiatry Today
Having an adequate vascular supply is a key tenet in wound care and limb salvage. Proper vascular assessment begins with pulse palpation and Doppler evaluation of the major arteries supplying the foot. Absent or weakly palpable pulses in conjunction with weak or non-Dopplerable signals should prompt referral to a vascular surgeon and ordering noninvasive vascular studies. The assessment of tissue perfusion is critical to predicting healing, predicting if an amputation is required and predicting the level that an amputation will most likely heal. Traditional methods of assessing tissue perfusion include clinical judgment, an ankle brachial index, toe pressures and a toe brachial index, toe arterial pulse waveforms, forefoot pulse volume recordings, duplex scanning, transcutaneous oxygen pressure measurements and skin perfusion pressure.
