[Delayed occurrence of compartment syndrome of the upper arm after shovelling snow by a patient under oral anticoagulation].

This article reports the case of an 81-year-old male patient under treatment with oral anticoagulation who suffered delayed compartment syndrome of the upper arm from arterial capillary hemorrhage after shovelling snow. The diagnosis was made 48 h after the initial symptoms in the emergency surgical department of the Klinikum rechts der Isar (München) with the presence of clear neurological deficits. Following computed tomography angiography (CTA) imaging an emergency dermatofasciotomy was carried out as well as a vascular ligature via a medial approach. Compartment syndromes are the result of pathologically elevated tissue pressure and as a rule with a rapid clinical course. A delayed diagnosis can therefore lead to irreversible tissue and nerve damage up to the loss of the extremity. Compartment syndromes are particularly frequent in the lower extremities whereas those of the upper extremities are rare. This case report is intended to raise awareness for an insidiously occurring compartment syndrome of the upper arm due to repetitive microtrauma (in this case shovelling snow) and arterial peripheral vascular hemorrhage with simultaneous anticoagulation. The necessary diagnostic and treatment steps are also elucidated.
