Evaluation methods of wound size defect in diabetic foot syndrome

Object. The study of the informativeness by various methods of visualizing the dimensions of wound defects and the dynamics of their healing in patients with diabetic foot syndrome (DFS).

Materials and Methods. The descriptive research analyzed various methods for determining the size of wounds in 77 patients with DFS. 63 (81.8 %) patients (1st group) were performed classical planimetry by film using. The wound size at 6 (7.8 %) patients (2nd group) was estimated by using a computer program, 8 (10.4 %) patients (3d group) underwent magnetic resonance imaging (MRI) their feet.

Results. In the course of the study, the median area of wounds in Group 1 patients were 25.0 [16.2; 44.5] cm2, median depth — 3.3 [1.5; 6.5] cm. It was required about 15–20 minutes of the expert work. The median area of wounds by patients Group 2, measured with the mobile application V2F, was 8.95 [6.8; 10.6] cm2. The depth determined by the same method was 0.25 [0.2; 0.5] cm. The study duration amount to 5 minutes approximately. The 3d patients Group that was measured with MRI had wound defects depth equal to 3.2 [2.6; 4.5] cm, wound area - 23.5 [12.3; 55.3] cm2. This study duration was similar to the standard MRI protocol.

Conclusion. The planimetric method of wound size analysis is a routine way for assessing the dynamics of the wound defects state, its size and depth. Determining the size of wounds with special software is rather quick and simple method, but it allows to evaluate only the planar characteristics of the wound and has a high error. The MRI procedure of a wound with an alginate dressing allows to reliably estimate the volume of wound defect and exclude the presence of a hidden infection focus.
