Necrotizing Fasciitis Causing Acute Compartment Syndrome after Radial Artery Catheterization

Necrotizing fasciitis is a rare but potentially fatal infection involving the subcutaneous tissue and fascia with the development of necrosis of these structures. Acute compartment syndrome occurs when increased pressure within a closed muscle compartment compromises the circulation and function of the tissues within that space. We report the case of a male patient who was admitted to the intensive care unit for the management of urosepsis due to an acute obstructive pyelonephritis complicated by cardiopulmonary arrest. A radial arterial catheter in the left arm was urgently inserted, under suboptimal aseptic technique. His clinical condition progressively deteriorated, and swelling of the left arm with extension to the forearm with incipient signs of compromised perfusion were observed. The diagnosis of necrotizing fasciitis with acute compartment syndrome was made and an emergency fasciectomy performed. Following this, the patient gradually improved, organ dysfunction resolved, and he was discharged without sequelae. LEARNING POINTS: Necrotizing fasciitis is a rare but potentially fatal infection that can cause substantial tissue destruction and lead to sepsis. In rare cases, it can cause acute compartment syndrome, which occurs when increased pressure within a closed muscle compartment compromises the circulation and function of the tissues within that space. Both necrotizing fasciitis and acute compartment syndrome can be a complication of an arterial catheterization performed under suboptimal aseptic technique; hence, rigorous daily physical examination of the site is crucial for timely diagnosis.
