1 Use of microcirculatory parameters to evaluate chronic venous insufficiency

Dorigo, PhD, Daniel Alexandre Bottino, MD, PhD, Eliete Bouskela, MD, PhD  Journal of Vascular Surgery  Volume 43, Issue 5, Pages (May 2006) DOI: /j.jvs Copyright © 2006 The Society for Vascular Surgery Terms and Conditions

2 Fig 1 The Cytoscan probe on the perimaleolar region fixed with a robot arm for data acquisition. Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2006 The Society for Vascular Surgery Terms and Conditions

3 Fig 2 The Cytoscan probe is positioned on a rectangular area (7.5 cm2) for microcirculatory observation. Ten windows are placed on a plastic mask to always provide the same position for the Cytsocan probe.

4 Fig 3 An illustration of microcirculatory parameters shows the analysis of one dermal papilla. This scheme shows a “glomerulus like” capillary skein that is normally seen in patients. DDP, Diameter of dermal papilla (μm); DCB, diameter of capillary bulk (μm); CD, capillary limb diameter (μm), and CM, capillary morphology.

5 Fig 4 Microcirculatory images in patients according to CEAP classification. Dashed lines show the diameter of the dermal papilla (DDP) and full lines show the diameter of the capillary bulk (DCB). Note the increasing in DDP and DCB values according to the severity of the venous disease (C0 to C5). Capillaries are more tortuous in C4 and C5 than in C0-C3.
