Twenty non-diabetic, stage II peripheral arterial occulusive (PAOD) patients were studied by (i) nailfold capillaroscopy, (ii) the evaluation of ankle/arm pressure ratio as measured by Doppler velocimetry, (iii) the measurement of systolic toe pressure using a photoplethysmographic method and (iv) the determination of transcutaneous oxygen tension (TcPO2) before and after an induced ischemia. Capillaroscopic patterns (stage 0 = 8 limbs; stage 1 = 16; stage 2 = 10; stage 3 = 6) correlated significantly (r = 0.688) with the TcPO2 half recovery times. No correlations emerged between the different capillaroscopic patterns, the ankle/arm pressure ratio and the toe systolic pressure even though the ankle/arm pressure ratio correlated with the toe systolic pressure (r = 0.670).

Abstract
Twenty non-diabetic, stage II peripheral arterial occulusive (PAOD) patients were studied by (i) nailfold capillaroscopy, (ii) the evaluation of ankle/arm pressure ratio as measured by Doppler velocimetry, (iii) the measurement of systolic toe pressure using a photoplethysmographic method and (iv) the determination of transcutaneous oxygen tension (TcPO2) before and after an induced ischemia. Capillaroscopic patterns (stage 0 = 8 limbs; stage 1 = 16; stage 2 = 10; stage 3 = 6) correlated significantly (r = 0.688) with the TcPO2 half recovery times. No correlations emerged between the different capillaroscopic patterns, the ankle/arm pressure ratio and the toe systolic pressure even though the ankle/arm pressure ratio correlated with the toe systolic pressure (r = 0.670).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
