Utilization of Lrinec Score for Early Diagnosis of a Necrotizing Soft Tissue Infection by Serratia Marcesens Complicated with Deep Vein Thrombosis

Abstract

Necrotizing fasciitis (NF) has a rapid clinical course and is associated with high mortality. Moreover, it involves a high index of suspicion and early aggressive intervention to reduce the risk of mortality. The overlap in clinical presentation in similar pathologies like abscesses, cellulitis, and deep vein thrombosis, can mask underlying NF, making the diagnosis even more challenging. This case presents multiple comorbidities that expedited the development of NF, while demonstrating a pragmatic approach to treating NF while balancing anticoagulation and emergent surgical intervention. The utilization of clinical judgement and a risk stratification score can help identify early cases of NF allowing for aggressive intervention.
