Factores de riesgo en la infección protésica vascular

we conducted a study for identifying the risk factors for vasular prosthetic infections. we carried out a biostatistical analysis using logistic regression, chi-square test, and relative risk estimations. risk factors found were post-operative femoral thrombectomy occlusion, diabetes mellitus, arteriography by seldinger method, and femoral anastomosis in the inguinal region. they were considered independent variables for infections in vascular protheses. in a multivariate analysis, the 4 risk fcators showed a relative risk over 1 with significant values (p 0,05). in a univariate, detected risk factors kept the same structure and the same statistical results were found. the outcome of the study was as follows: infested protheses, 12 of 318 protheses (3.8 %), femoral anastomosis, 281 of 318 (88 %); diabetes, 12 of 318 (4 %); femoral arteriography, 39 of 318 (12 %); femoral thrombectomy, 23 of 318 (7 %); aortic enteric fistulae, 2 of 318 (0.6 %); amputations due to sepsis, (0.3 %) and early mortality from prosthetic sepsis, 4 (1 %). we agreed with the world literature as to the prophylactic use of antimicrobial agents. we set forth the main measures to be considered for the profilaxis of vascular prosthetic infections.
