Can Extravasation Injury Cause Subcutaneous Compartment Syndrome of the Hand?

Abstract

Background: Compartment syndrome of the hand is a well-described phenomenon with potentially devastating consequences. Although numerous mechanisms have been proposed, the extravasation of peripheral intravenous (IV) fluids remains a relatively rare etiology. Objective: Surgical dogma mandates emergent decompressive fasciotomies in the presence of hand dysfunction and impending tissue loss from supraphysiologic compartment pressures. The role of the subcutaneous space in acute compartment syndrome remains unclear. Methods: In this report, we present a case of a dorsal hand IV extravasation leading to an acute compartment syndrome of the subcutaneous space. Results: An emergent skin-only incision was used for decompression, with immediate improvement in symptoms and no long-term adverse sequelae. Discussion: The subcutaneous space appears capable of sustaining supraphysiologic pressures that impair cutaneous perfusion. This closed anatomic space can be readily decompressed, resulting in rapid improvement in soft tissue perfusion. However, its role in contributing to acute compartment syndrome of the hand requires further research. Conclusion: We propose consideration of the subcutaneous space as a distinct hand compartment and advocate selective compartment release when prudent.
