Influence of arterial disease, age and active ulceration on venous refilling time measured by photoplethysmography

This study investigated the influence of arterial disease, patient age and the presence of a venous ulcer on venous refilling time as measured by photoplethysmography. Refilling time was evaluated in 157 control limbs, in 133 limbs with venous disease, in 17 limbs with arterial disease and in 20 limbs with mixed disease (arterial and venous disease) as the cause of ulceration. Refilling time reduced progressively with age in control subjects …
