Management of Purpura Fulminans Skin Loss at a Regional Burns Centre: Sixteen-year Experience

Introduction: Purpura fulminans (PF) is a rare syndrome of cutaneous purpura which is the consequence of severe circulatory shock causing intravascular thrombosis, haemorrhagic necrosis, and consequent tissue loss. The aim of this study was to present our 16-year experience of managing PF in a regional burns centre. Methods: We performed a single-centre retrospective case series of all patients admitted to the St Andrews Burns Centre at Broomfield Hospital, Chelmsford, Essex, UK, between June 2006 and July 2022 with a diagnosis of PF. Data were extracted by retrospectively searching hospital case notes. Results: Thirteen individuals were identified [five children (mean age 5, range 1-14) and eight adults (mean age 39, range 24-54)]. The total body surface area of cutaneous necrosis ranged from 5% to 80%, with a mean of 27.2%. Patients were treated with an established surgical sequence of total wound debridement and immediate coverage with a cadaveric allograft, followed by staged wound autografting. The mean time from disease onset to wound autografting was 37.3 days (range 20-64 days). Eight individuals (61.6%) required major amputation of at least one limb (proximal to the ankle or wrist joint). Only one mortality (of 80% total body surface area skin loss) was observed in the identified cohort. Conclusions: The large body surface areas often involved in PF cases make management of these wounds well suited for burns centres, wherein established facilities and multidisciplinary teams exist that are familiar with managing large cutaneous burns. We provide a suggested algorithm to aid the management of PF. (c) 2023 British Association of Plastic, Reconstructive and Aesthetic Surgeons. Published by Elsevier Ltd. All rights reserved.
