Fulminant Necrotizing Soft Tissue Infection Following Abdominal Liposuction: Comprehensive Literature Review and Case Report

Necrotizing soft tissue infection (NSTI) is a rapidly progressive, life-threatening soft tissue infection that involves the skin, subcutaneous tissue, and fascia, with a natural evolution to septic shock and death if not treated. NSTI is typically associated with trauma, and rarely reported as a complication of aesthetic procedures such as liposuction. We report the case of a previously healthy 34-year-old woman who developed fulminant necrotizing soft tissue infection shortly after undergoing abdominal liposuction in a suspected non-accredited facility. She arrived at our institution with severe thoracoabdominal pain, ecchymosis, and refractory shock within hours postoperatively. Imaging studies performed in the emergency department revealed gas in the soft tissues, confirming the diagnosis. Emergent surgical debridement exposed extensive necrosis affecting a large body surface area. The patient required multiple surgeries, intensive care support, and broad-spectrum antibiotics to achieve infection control. Reconstructive treatment was initiated once stabilization was achieved, leading to full wound closure and a favorable clinical outcome. In addition, we provide a comprehensive review of the current literature regarding necrotizing soft tissue infection, emphasizing this condition as a postoperative complication, including its epidemiology, microbial etiology, pathophysiology, diagnostic challenges, treatment strategies, and reported cases. This review aims to contextualize this rare but severe postoperative complication and to guide clinicians in its early recognition and management, while also raising awareness about the potential consequences of aesthetic procedures performed in unregulated settings.
