Introduction. Chronic venous insufficiency (CVI) has an important impact on the public health system in particular due to the occurrence of chronic venous ulcers (UCV) and infections.
Objective. To evaluate cultures of biopsies of chronic venous ulcers of patients who suffered an acute change in the intensity of pain of the lesion.
Method. Antibiograms of the cultures of chronic venous ulcer biopsies of patients who suffered an acute change in the lesion with significant pain for 24 hours were evaluated. All patients were treated between 2011 and 2015 in the Vascular Surgery Outpatient Clinic of the Medical School in São José do Rio Preto. Other causes of pain such as chronic arterial insufficiency and problems with the dressings were ruled out.
Results. Positive cultures were detected in 34 of the 35 patients whose pain was resolved by antibiotic therapy.
Conclusion. Acute changes in the intensity of pain associated with chronic venous ulcers seem to be related to local infectious disease.
