The applications of negative-pressure wound therapy (NPWT) have achieved remarkable diversification. Initially used in the therapy of soft tissue wounds related to open fractures, this technique led to the understanding of the complex mechanisms underlying it. This paper aims to analyze the evolutionary scenarios of a group of patients with heterogeneous lesions under negative pressure aspiration treatment. We aimed to identify and analyze various associated pathologies that have the potential to negatively influence the healing process under negative pressure treatment and implicitly analyze the particularities of representative cases for the group whose evolution under treatment proved to be unfavorable. Retrospective, observational study, type series of cases focused on a group of 17 hospitalized patients, who received treatment by negative aspiration, between 2015-2019 in the Surgery Department of the University Emergency Hospital Bucharest. Regarding the obtained results, diabetes mellitus, obliterating arteriopathy, and anemia had a prevalent distribution in the group with unfavorable evolution. The glycemic value can predict 17% of the evolutionary scenario of a patient (favorable/unfavorable) being necessary an integrative therapeutic conduct. Concluding, although an extremely promising therapeutic option, NPWT can prove to be disappointing given its impact in the background of suboptimally managed comorbidities.
