AM J PHYS MED REHABIL , 2004, vol. 83, n° 6, p. 486-491 Doc n°: 114191 Localisation : Documentation IRR Descripteurs : EB31 - AMPUTATION TRANSFEMORALE, EC16 -PROTHESE DE MEMBRE INFERIEUR Videocapillaroscopy is a new technique allowing a noninvasive examination of the capillary framework of the skin by using a contact probe with magnifying lenses and a cold-light epiluminescence system. The aim of this article was to investigate, by videocapillaroscopy, the microcirculation of the skin of the stump In 70 consecutive patients with unilateral transfemoral amputation. Patients were divided into two subgroups according to their tolerance (A) or intolerance (B) to a prosthesis with an Icelandic-Swedish-New York socket. Subgroup A included 48 patients, 17 diabetic and 31 nondiabetic, and subgroup B included 22 patients, 16 diabetic and 6 nondiabetic. In subgroup B, the caliber of capillary loops was significantly larger (mean +/- standard deviation, 23.6 +/- 2.04 vs. 16.2 +/- 1.96 mum; P < 0.001), neoangiogenesis was significantly more frequent (82% vs. 25%, P < 0.001), and the presence of microaneurysms (64% vs. 15%, P < 0.001) and microhemorrhages (36% vs. 4%, P < 0.001) was also more frequent. Surprisingly, some such diabetes-like microvascular changes were also found in the six nondiabetic patients of subgroup B. By using multiple logistic regression analysis, intolerance to the prosthesis was significantly related to microvascular changes (P = 0.001) but not to diabetes (P = 0.601), although diabetes was unequally distributed in the two subgroups.
