The degree of circulatory insufficiency in Raynaud's phenomenon, Buerger's disease or digital replantation has been evaluated only by clinical symptoms and signs or angiograms. Objective evaluation methods of the disability of digits are crucial for proper management of patients with circulatory insufficiency of digits. Angiogram, Doppler, electromagnetic flowmeter, laser blood flowmetry, mechanical blood flowmetry has been used for the evaluation of the circulatory insufficiency, however, the data was affected by time, place, room temperature and patient's emotional state. In fact, many methods are unreliable, expensive and difficult to perform. Photo plethysmography can measure the absorption amount of light at different wavelength. Summation of the absorbed and emitted amount of light evenly match the input amount. Photo plethysmography evaluates qualitative blood flow differences by comparing normal fingers and replanted fingers.
So we designed the two channel photo plethysmography to compare digital blood flow between dominant hand to non dominant hand and replanted fingers to opposite normal fingers in 202 pairs of fingers in 44 patients. The average digital blood flow in both hands showed no difference but replanted digits showed 53% compare to opposite normal digits. In each patient, the blood flow of each digit showed significant difference. In conclusion, photo phlethysmography is a sensitive, reliable, and useful tool for evaluating blood flow for circulatory insufficiency of tissues such as fingers and toes.
