Extracorporeal membrane oxygenation cannula-related chronic wound with a retained suture in a neonate.

Extracorporeal membrane oxygenation (ECMO) is often employed to manage persistent pulmonary hypertension of the newborn where non-invasive therapies have failed. Delivery of ECMO requires insertion of indwelling catheters into central or peripheral vasculature; and this predisposes the recipient to development of catheter-associated skin infection; however, chronic non-healing wounds with granuloma formation are rare. We describe a case of an 8-month-old child who presented to our Plastic Surgery Services with a chronic left groin wound at ECMO cannula insertion site that failed medical management. The patient underwent wound exploration and debridement during which an old non-absorbable suture localized at the base of the wound was discovered. The foreign material as well as granuloma was removed, leading to the resolution of the chronic skin lesion and patient recovery without major complications. To our knowledge, this is the first case report describing an ECMO-associated paediatric chronic wound. Published by Oxford University Press and JSCR Publishing Ltd. All rights reserved.
