[Compartment syndrome of the leg secondary to a muscle tear in an anticoagulated elderly patient].

Compartment syndrome is a clinical-surgical condition characterized by an increase in intracompartmental pressure that leads to progressive tissue damage and can have devastating consequences if not treated promptly. High-energy trauma is the most common cause, though in frail and anticoagulated patients, it can arise from daily activities. We present the case of a 63-year-old man with multiple comorbidities and anticoagulant therapy who developed compartment syndrome secondary to a muscle tear and required decompressive fasciotomy. Early suspicion of compartment syndrome in anticoagulated patients with atypical mechanisms is essential to avoid diagnostic delays and ensure timely, appropriate treatment.
